CCAC NDC Watch - Pre-COP Review of the Latest on Non-CO₂ Pollutants in National Climate Plans by Climate and Clean Air Coalition Secretariat (CCAC) - 7 November, 2025 Share SHARE Facebook share Twitter LinkedIn Copy URL Email Print Breadcrumb Home News and Announcements CCAC NDC Watch - Pre-COP Review of The Latest On Non-CO₂ Pollutants In National Climate Plans This blog is part of a series tracking and analysing Nationally Determined Contributions (NDCs) as they are updated and released in the lead-up to COP30. Stay tuned for ongoing insights on how countries are integrating non-CO₂ pollutants, air quality, and public health benefits into their national climate commitments. Last week the UNFCCC Secretariat released a report synthesising information from the 64 new nationally determined contributions (NDCs) released in 2025 to 30th September. The report highlights real and increasing progress on action to address climate change. Super pollutant inclusion is increasing Our analysis finds that countries party to the Paris Agreement are increasingly including action on super pollutants as part of the suite of strategies integrated in their NDCs. Image This is demonstrated in the number of countries covering super pollutants by their overall greenhouse gas mitigation target. Compared to pre-2020 NDCs the number of latest NDCs covering methane, nitrous oxide, HFCs has increased by 22%, 22%, and 61% respectively. While not strictly recommended (see CCAC Guidance) inclusion of black carbon doubled, while the inclusion of non-methane tropospheric ozone precursors tripled, indicating increased ambition on both pollutants. The number of countries including additional quantified targets or assessing the mitigation potential of the measures included in their NDC has also grown significantly from a base of nearly zero in pre-2020 NDCs, with only two NDCs including black carbon in this way. As of 30 September, 35 countries include a quantified methane target or assessment of mitigation potential in their latest NDC, while 23 and 9 include HFCs and black carbon in this way respectively. Image The increasing specificity of super pollutant inclusion is important, not only does it increase the transparency and clarity of how the overall economy wide greenhouse gas reduction target will be achieved, it helps to account for the different effects that super pollutants have compared to CO2 on near term climate and air quality. Clear and transparent inclusion of mitigation ambition in this way also support the tracking of progress towards other international goals, for example, the Global Methane Pledge, or Kigali Amendment to the Montreal Protocol.Included in these numbers are NDCs released since our last NDC watch blog, which covered NDCs submitted to the end of July 2025. See below for a summary of these NDCs. Since 30 September, 19 countries and the EU have released their NDCs, including: Azerbaijan, the Bahamas, Cabo Verde, China, Côte d'Ivoire, Fiji, Guinea, Indonesia, Kyrgyzstan, Malaysia, Mauritania, Mozambique, Paraguay, Peru, South Africa, Thailand, Uzbekistan, Venezuela and Zambia. NDCs submitted in August and September Angola Angola’s NDC underscores the co-benefits of its mitigation activities for public health and air quality. For example, the NDC notes that capturing and using methane from landfills to generates electricity not only reduces emissions but also improves hygiene and public health in urban areas. These co-benefits are also highlighted in relation to the implementation of hydroelectric and solar projects and the electrification of public transport, particularly buses in high-density areas. Australia Methane, nitrous oxides and HFCs are included in Australia’s overall mitigation target. The NDC notes how HFC phase down contribute to its overall mitigation target, toward an 85% reduction from baseline in 2036. The NDC also mentions Australia's commitment under the Global Methane Pledge and notes the air pollution and public health co-benefits (with associated cost savings) of implementation of mitigation measures. Bangladesh Bangladesh’s NDC addresses super pollutants through: methane reductions in rice cultivation, livestock manure management, and wastewater treatment; precision fertiliser use to curb nitrous oxide emissions; and a 10% HFC phasedown in line with its commitment under the Kigali Amendment. Barbados Barbados’ overall mitigation target covers methane, nitrous oxide, and HFCs. Barbados underscores its commitment to the phase down of HFCs under the Kigali Amendment to the Montreal Protocol through a section on Cooling and Short-Lived Climate Pollutant Management. Barbados outlines a number of plans and measures including the 2022 National Cooling Strategy, which advances phase-down of HFCs and transition to low-GWP, energy-efficient refrigeration and air-conditioning technologies in line with the Kigali Amendment. Methane reduction is targeted through waste sector actions - a new landfill with methane flaring by 2028, a 20% reduction in solid waste generation by 2030, and a 9 MW waste-to-energy plant by 2035. Transport electrification and clean-energy transition measures identified in the NDC are also expected to contribute to co-benefits for air quality and reduced black-carbon and ozone-precursor emissions. Bolivia Bolivia includes methane, nitrous oxide and HFCs in its overall mitigation target. The NDC highlights methane as a target of agriculture and waste measures and also highlights the reduction of air pollution in urban areas as a result of a transition to electric vehicles. Cambodia Cambodia’s NDC includes super pollutants in a number of ways: Cambodia commits to phasing down HFCs conditionally by 1.8 MtCO₂e and conditionally 2.4 MtCO₂e over a 10-year period. Cambodia describes its intention to reduce methane through the measures it identifies:Promote improved rice straw management practices by discouraging open-field burning and encouraging alternative uses such as composting, mulching, biochar production, or incorporation into soil, combined with improved water management to avoid long anaerobic periods that could lead to methane emissions.Encourage the adoption of feed additives in cattle production systems to improve feed efficiency, enhance animal health, and reduce enteric methane emissions. Air quality is a major co-benefit identified for many measures. Air quality measures are included as adaptation measures, including strengthening AQ monitoring and regulation, with a goal of extending both to black carbon. Cambodia highlights the role of improved air quality in strengthening health resilience. Chile Not only does Chile's NDC include methane and nitrous oxide and HFCs in the scope of its overall greenhouse gas mitigation target, it sets specific quantified targets for methane and black carbon and makes qualitative statements about how it intends to reduce HFCs. By 2025, Chile commits to reversing the upward trend in national methane emissions (excluding LULUCF). Additionally, it commits to a 10% reduction by 2035, compared to peak emissions.Improve air quality by reducing concentrations of fine particulate matter through targeted actions on black carbon (BC) emissions: (a) by 2030 reduce BC emissions by at least 25% compared to 2016 levels; (b) by 2035, reduce BC emissions by at least 30% compared to 2016 levels; (c) by 2035, achieve PM2.5 concentrations equal to or less than 18 μg/m3 moving towards the levels recommended by the WHO.Chile's NDC 3.0 is also explicit about the link between air pollution and climate change, short-lived climate pollutants (SLCP) and the benefits of integrated action. It links methane to tropospheric ozone formation, and highlights the health effects of air pollution. It outlines air pollution planning and SLCP mitigation as an important component of subnational action. Colombia Colombia’s draft NDC, Transformaciones para la Vida, establishes an economy-wide greenhouse gas reduction pathway toward net-zero emissions by 2050, with intermediate targets for 2035. The NDC does not list the gases covered by the national mitigation goal, and these are expected to be communicated in the final version of NDC. The NDC reaffirms Colombia’s participation in the Global Methane Pledge, and includes measures in the waste, fossil fuel and agriculture sectors that will reduce emissions of methane.The NDC introduces an explicit black carbon reduction target, committing to a 40 percent reduction below 2014 levels by 2030. Three key strategies are identified to achieve this: (1) Implementation of Euro IV (2015) and Euro VI (2023) emission standards for on-road diesel vehicles. (2) Introduction of Tier 4 Interim (Stage IIIB) emission standards for off-road machinery nationwide. (3) Progressive reduction of agricultural residue burning across key crop systems.The NDC also includes a commitment to reduce the use of high-global-warming-potential refrigerants framed under a circular economy approach, described as: “The reduction in the use of ozone-depleting substances with high global warming potential, accompanied by technological advancements in domestic refrigeration and air conditioning.” Cuba Cuba has submitted an updated NDC that specifies a set of policies and measures that represent its commitment to climate change mitigation. Many of these actions, including renewable electricity generation, expanding the share of electric vehicles, will also reduce black carbon and other air pollutants. Two measures identified in the NDC are noteworthy for their SLCP reduction potential. First, Cuba commits to reduce emissions from its dairy cattle. Currently, 36% of Cuba’s greenhouse gas emissions are from methane, the majority of which comes from livestock. Cuba’s NDC notes that the livestock population is projected to double by 2050, which could lead to a substantial increase in methane emissions. Cuba outlines that changes to the dairy cattle diet, improved manure management, and expanding silvopastoral systems will all be implemented to reduce methane emissions from this sector. Secondly, wastewater is an often overlooked methane source that emits as much methane as solid waste but is substantially less covered within NDCs. Cuba commits to improving the treatment of wastewater from sugar refineries. Organic matter in the water effluent from sugar processing plants can decompose and release significant quantities of methane. Cuba commits to implementing improved wastewater management at 11 sugar refineries. CCAC work has shown in Mexico that sugar processing is also a substantial source of black carbon emissions. It may therefore be helpful to consider integrated strategies to deal with both methane and black carbon to multiply the benefits from action in sugarcane processing. Eswatini Eswatini’s NDC 3.0 includes super pollutants within its overall mitigation target, explicitly listing methane, HFCs, black carbon, and other air pollutants such as particulate matter, nitrogen oxides (NOx), sulphur dioxide (SO₂), ammonia (NH₃), carbon monoxide (CO), and non-methane volatile organic compounds (NMVOCs). The NDC contains a quantified HFC phase-down plan aligned with the Kigali Amendment, freezing consumption at 2024 levels, reducing by 10 percent by 2030 and 80 percent by 2045, alongside substitution with low-GWP refrigerants and recovery systems. Methane mitigation measures are included, including improved manure management, adoption of climate-smart agriculture, and methane-reduction strategies in communal grazing areas by 2030. While targets and measures related to black carbon and particulate matter emissions include a 30 percent reduction in open burning of waste by 2035, clean-cooking expansion, non-incineration medical-waste technologies, cleaner transport and fuel standards, and community-based fire management. Ethiopia Ethiopia’s NDC highlights methane as key to mitigation in the livestock sector, highlighting measures to improve productivity, enhance feed efficiency, and shift herds toward small ruminants and poultry to reduce methane intensity. Waste-sector actions include expansion of climate-resilient disposal sites and improved management practices that further lower emissions. Other measures in the energy and transport sectors, including large-scale renewable power generation, promotion of clean cooking, and an electric-vehicle strategy with a ban on new internal-combustion-engine imports, are expected to cut emissions and reduce urban air pollution. Federated States of Micronesia The Federated States of Micronesia's (FSM) includes methane and nitrous oxide within the scope of its overall mitigation target. Although HFCs are not included in this overall target, FSM commits to a 10 percent reduction in HFCs by 2029 and 30 percent by 2035 in line with the Kigali Amendment to the Montreal Protocol. Measures include monitoring imports, preventing refrigerant leaks, and transitioning to low-global-warming-potential alternatives.Methane reduction is a major focus in the waste and agriculture sectors. Waste measures include improving landfill management, promoting composting, and deploying anaerobic biodigesters for household and piggery waste. These actions in the waste sector are expected to achieve a 12 percent reduction in methane emissions below 2020 levels, avoiding approximately 77 kt CO₂e by 2035. In the agriculture sector, measures included enhancing livestock productivity and the use of compost-based organic fertilizers.FSM notes that black carbon reductions are expected from energy and transport actions that replace diesel generation with renewable electricity - targeted to reach 80 percent by 2035, which could reduce black carbon emissions 65%. The Holy See The NDC for Holy See and the Vatican City covers methane, HFCs and nitrous oxide in the scope and coverage of its overall target. To achieve this target, the NDC outlines measures across energy, industrial processes and product use, land use, and forestry. Honduras Honduras’ overall mitigation target includes methane, nitrous oxide and HFCs as well as non-methane volatile organic compounds. The target covers the energy, industry agriculture and waste sectors. Iceland Iceland includes methane and HFCs in its overall mitigation target of “50–55 per cent net reduction of greenhouse gas emissions by 2035 compared to 2005”, in sectors covered by the scope of the EU’s Effort Sharing Regulation (ESR): road transport, energy production, fisheries, product use, agriculture and waste management. Jamaica Jamaica intends to reduce emissions by 16.3% by 2030 and 16.9% by 2035 (compared to 2012 levels). Jamaica’s overall mitigation target includes methane, nitrous oxide and HFCs and covers the energy and industrial sectors as well as land and land use change. Jordan Jordan’s overall mitigation target includes methane, nitrous oxide and HFCs. Jordan aims to achieve its overall target by addressing emissions from power generation, with a focus on scaling up renewable energy, transport (especially e-mobility), and improvement waste management and agriculture practices.The NDC also notes the encouragement of “clean air and clean cooking initiatives around health and education facilities to reduce local pollution and improve child respiratory health.” Lebanon Lebanon’s overall mitigation target includes methane, HFCs and nitrous oxide across the energy, industrial, agriculture and waste sectors. The NDC notes how “air pollution, intensified by higher temperatures and wildfire smoke, is worsening respiratory conditions such as asthma and Chronic Obstructive Pulmonary Disease (COPD), increasing hospital admissions.” Liberia Liberia’s overall mitigation target includes methane, nitrous oxide and HFCs, and covers the energy, transport, agriculture, waste and industrial sectors. The overall mitigation target also includes tropospheric ozone precursors non-methane volatile organic compounds (NMVOCs), carbon monoxide, and nitrogen oxides (NOx) as well as sulphur dioxide (SO2)In the industrial sector Liberia commits to a 20 percent HFC reduction by 2035, explicitly referencing the Kigali Amendment and a national HFC tax. Agriculture measures such as low-emission rice cultivation, organic fertilizers, and improved livestock management, will reduce methane and nitrous oxide in line with Liberia’s National Methane Roadmap (2024). In the transport sector, measures include cleaner bus fleets, and adoption of Euro VI emission standards – measures that will have co-benefits for air quality. Liberia also outlines its ambition to, by 20230, include short-lived climate pollutants in its next national inventory. Liechtenstein Liechtenstein’s overall mitigation target includes methane, nitrous oxide and HFCs across the energy, industry, agriculture and waste sectors. Mitigation measures are implemented through existing legislation, including the CO₂ Act, the Energy Efficiency Act, and the Emissions Trading Act, which establish carbon pricing, fuel-efficiency standards, and participation in the EU Emissions Trading Scheme. Actions include improving building insulation, switching to district heating and heat pumps, electrifying transport, and promoting energy efficiency and renewable energy use. Agriculture and waste are identified as smaller sources where further reductions are planned. Mauritius Mauritius’ NDC includes methane and nitrous oxide through quantified mitigation targets in the agriculture and waste sectors, such as a 10% reduction from animal waste and an estimated 43.8 Gg CO₂e reduction potential in wastewater management. The NDC highlights Mauritius’ commitment to the Kigali Amendment, with HFC phasedown targets of 10% by 2029, 30% by 2030, and 80% by 2045. Air pollution is mentioned as a co-benefit of decarbonisation in the transport and port sectors. Maldives The Maldives has committed in its new NDC to reduce 1.52 million tonnes of greenhouse gas emissions by 2035, about 25% of their projected emissions in a baseline scenario. To achieve this, they have more than doubled their renewable electricity generation target from 15% to 33% of electricity production. Achieving this will also reduce black carbon and other air pollutants from the diesel generators currently providing emissions. Clean air benefits will also result from the measures identified for road transport, including switching to electric vehicles, improving public transport and implementing vehicle emission standards. The CCAC has supported the Maldives through development of a National Action Plan on air pollutants and cost-benefit analyses to understand the clean air benefits of these actions in the transport sector. The Maldives also highlighted links between air quality and adaptation, noting growing concerns about the impact of transboundary air pollution on water quality and security. Moldova Moldova becomes one of only a few countries with a methane-specific target in its NDC. Moldova commits to reduce greenhouse gas emissions by 75% by 2035 compared to 1990 levels, and to achieve climate neutrality by 2050. Moldova highlights their participation in the Global Methane Pledge (GMP) and outlines that achieving its overall GHG target will also reduce its methane emissions by 64% by 2030 and by 68% by 2035 compared to 1990 levels. This target is equivalent to it reducing its methane emissions by 11% by 2030 and 21% by 2035 compared to 2020 levels. To achieve these reductions, Moldova will need to focus on reducing methane emissions from solid waste, which make up about half of national methane emissions; the energy sector, particularly pipeline leaks, which make up 19% of methane emissions; and livestock, which contributes 18%. Moldova’s NDC could further reduce the rate of warming in the near term through reductions in hydroflurocarbons. The updated NDC outlines that Moldova has legislated to phasedown HFCs according to the Kigali Amendment schedule, and specifically highlights this as an opportunity to further reduce greenhouse gas emissions by improving the energy efficiency of refrigeration at the same time. Moldova’s NDC is clear about the burden its citizens suffer from exposure to poor air quality, and the opportunity of the NDC to achieve cleaner air. The NDC states that every year up to 3,000 people die early due to air pollution levels Moldova, and highlights results from a World Bank study that estimates that emission reduction efforts in the energy sector alone could reduce particulate matter concentrations by 84% and prevent 4,100 premature deaths by 2050. Because these actions focus only on the energy sector, the true health benefits from Moldova’s NDC are likely higher. The air pollution benefits from Moldova’s NDC could play an important role in building public support for climate action. According to a public survey cited in the NDC, while 68% of respondents expressed concern about climate change, only 20% were aware of the Moldovan Government’s efforts to address the issue. The same survey highlighted even higher levels of concern (84% of respondents) about air pollution. Emphasising the NDC’s potential to contribute to cleaner air therefore supports climate action while also addressing other issues of significant concern to citizens. Mongolia Mongolia’s overall mitigation target includes methane and nitrous oxide. Mongolia also highlights its participation in the Global Methane Pledge.The impact on human health is described as the “greatest negative impact of climate change on society” and “is directly linked to environmental conditions, including clean air”. The NDC notes challenges related to rapid urbanisation and air pollution, including black carbon emissions, waste management, social services, traffic congestion. Morocco Morocco’s NDC maintains an economy-wide target that covers methane, nitrous oxide and HFCs. Additionally, the target covers tropospheric ozone precursors - nitrogen oxides (NOx), carbon monoxide, and non-methane volatile organic compounds (NMVOCs) – and sulphur dioxide (SO2). Morocco’s NDC introduces its National Methane Roadmap to 2050, which has been developed under Morocco’s participation in the Global Methane Pledge. The NDC sets a target to reduce methane emissions by 23.5% by 2030 and 31.7% by 2050 under a moderate scenario, and by up to 36.2% in 2030 and 56.8% in 2050 under an ambitious scenario. Nepal Nepal’s NDC increases transparency on how it aims to achieve its emissions reduction target. The updated NDC of Nepal commits to reduce greenhouse gas emissions by approximately 27% by 2035 compared to a baseline emissions projection. Nepal’s NDC also provides useful, and detailed, information as to how this goal will be achieved, which in turn allow the impact on Short-Lived Climate Pollutants to be understood. In common with many of the updated NDCs, an upgrade to Nepal’s NDC is the inclusion of sectoral pathways, showing how the overall target will be achieved through reductions in different sectors. For example, achieving Nepal’s NDC will result in emissions from the waste sector being 44% lower in 2035 compared to the baseline – and will require deep cuts in methane emissions. Nepal sets a target to reduce the number of air pollution related deaths. The country’s capital Kathmandu, located in a valley, frequently experiences high pollution episodes and is often reported on as one of the most polluted cities in the world. It is clear that the NDC could achieve substantial air pollution benefits, including a specific target to reduce air pollution-related mortality - to 77 premature deaths per 100,000 people in 2030, and to 60 per 100,000 by 2035. Given that current mortality rates from air pollution are more than 150 premature deaths per 100,000, according to the Global Burden of Disease, these targets would more than halve air pollution’s health burden in Nepal, transforming public health. The NDC includes specific actions and targets that can help achieve its air quality goal alongside greenhouse gas emission reductions. By 2035 Nepal aims to have 2.1 million households cooking using electricity, 1 million households using improved efficiency biomass stoves, which will both contribute to substantial improvements in household air pollution. By, 2035, Nepal aims to have 95% of private vehicles sales being battery electric, reducing greenhouse gas and air pollutant emissions from transport. Finally, Nepal explicitly acknowledges the necessity for its climate plans to achieve other benefits, including for air pollution. To achieve, this, it states that during NDC implementation, ‘co-impact’ analyses will be conducted to ensure that these co-benefits are also being achieved. The Climate and Clean Air Coalition has developed guidance that can be used to monitor climate change plans to ensure they are also achieving reductions in Short-Lived Climate Pollutants, air pollutants and public health. Nicaragua Nicaragua’s overall mitigation target includes methane, nitrous oxide, and for the first time HFC emissions. It notes “the strategic objective of the regulation is to ensure the preservation of the ozone layer and mitigate climate change by limiting the use of substances with high global warming potential, such as HFCs.” Nigeria Nigeria’s overall target covers methane, nitrous oxide and HFCs. In addition the NDC explicitly refer to short-lived climate pollutants noting that it addresses SLCP mitigation in several measures and actions.These measures include phasing out of routine flaring and reduction of fugitive emissions in the oil and gas industry, adoption of renewables and cleaner fossil fuels under fuel combustion, reduction of enteric fermentation, and improved manure management, Systems Rice Intensification, reducing biomass burning, and improved solid and wastewater treatment. The NDC notes that “as a party to the Global Methane Pledge, Nigeria has committed to eliminate routine flaring by 2030 and to reduce fugitive emissions from leaks in the oil and gas industry by 95% by 2050.”Nigeria highlights the contribution of SLCPs to near-term warming and linkins their mitigation to improved air quality. The NDC estimates that over 21,000 premature deaths could be avoided annually as a result of reduced PM2.5 concentrations, with avoided mortality valued at $6–9 billion. Pakistan Pakistan includes methane, HFCs and nitrous oxide in its overall mitigation target. Pakistan emphasises its commitment under the Kigali amendment, which guides mitigation actions to reduce direct and indirect emissions from the Refrigeration and Air Conditioning sector through energy-efficient and environment-friendly cooling technologies. Pakistan references the National Clean Air Policy (NCAP-2023) and notes measures such as the reduction of crop burning, which will improve air quality. Panama Panama included methane mitigation within the scope of its overall target. In the agriculture sector, measures include improved nutrient and nitrogen management, implementation of the NAMA for rice and livestock, and sustainable production practices that reduce methane intensity. In waste, policies aim to decrease per-capita waste generation and increase recycling and circular-economy measures, reducing landfill methane emissions.Panama also commits to implementing the Kigali Amendment Roadmap and the National Cooling Plan, promoting refrigerant substitution and modernization of cooling systems to phase down HFCs.Panama also highlights that mitigation and adaptation actions can generate “positive impacts such as improved air quality and public health.” Russian Federation Russia’s overall greenhouse gas mitigation target covers all IPCC sectors and greenhouse gases, including methane, nitrous oxide and HFCs. Saint Vincent and the Grenadines Saint Vincent and the Grenadines overall target covers methane, nitrous oxide and HFCs. CH₄, N₂O, and HFCs - across the energy, transport, industry, agriculture, LULUCF, and waste sectors. Measures highlighted include plans to reduce landfill emissions and develop waste segregation systems, as well as incentives for low-emissions vehicles. The latter would directly yield co-benefits for air quality and reductions in emission of black carbon. São Tomé and Príncipe São Tomé and Príncipe covers methane and nitrous oxide in its overall mitigation target. The NDC outlines measures in the electricity and transport sectors, which will have cobenefits for air quality. Seychelles The Seychelles also specifically quantifies the methane emission reduction expected in the waste sector under this target, which aims for an 80% reduction in methane emissions by 2035.Due to the national capacity, Seychelles' NDC did not provide details on the mitigation measures in specific sectors. Notably, mobilising international support is one of the priorities to achieve the NDC targets. Serbia Serbia includes methane, nitrous oxide and HFCs in its overall target, covering the energy, industrial, agriculture and waste sectors. Solomon Islands The Solomon Islands sets out how different sectors will contribute to the overall achievement of the target, and specifies the breakdown of pollutants in this overall CO2e target. Methane mitigation in from the livestock subsector and through solid waste management will contribute to 2.4 ktCO2e/yr and 35.8 ktCO2e/yr of mitigation respectively. Somalia Somalia’s overall target addresses methane, HFCs and nitrous oxide. Methane is identified as the largest contributor to national emissions (49%), primarily from livestock, manure management, and waste. The NDC outlines several measures that will reduce methane emissions, including climate-smart agriculture, improved livestock and manure management, rangeland restoration, and waste-to-energy initiatives.HFCs are addressed under the Industrial Processes and Product Use (IPPU) and through a dedicated section on “Advancing Cooling Solutions.” Somalia commits to phasing down high-GWP refrigerants and improving energy efficiency in cooling systems, in line with the Kigali Amendment and the Global Cooling Pledge adopted at COP 28.Air quality is not explicitly mentioned, but measures such as the promotion of clean cooking fuels and technologies, improved cookstoves, sustainable charcoal production, and the reduction of open burning are likely to yield black carbon and air pollutant emissions reductions Sri Lanka Sri Lanka’s overall target addresses methane, HFCs and nitrous oxide, and includes detailed descriptions of the measures to achieve the overall mitigation target. The NDC recognises the importance of methane reduction measures in the waste sector, such as solid waste landfill methane capture and methane-to-energy projects in wastewater treatment. Air quality is mostly considered as a co-benefit of climate mitigation measures. However, notably, climate mitigation has been considered as a co-benefit of one air pollution measure - the Vehicle Emission Testing (VET) programme - originally designed to address urban air pollution has led to a reduction in CO2. Tonga Tonga’s NDC covers methane and nitrous oxide in the scope of its overall greenhouse gas mitigation target. Tonga includes measures to address methane including the introduction of low-methane livestock management programmes, including improved breeding, nutrition, vaccination, and sustainable manure management. In the waste sector, actions include expanding community composting, establishing a national waste database, and upgrading landfills with leachate and gas-monitoring systems to reduce methane from organic waste decomposition.While HFCs are not covered by the overall target, their emissions are addressed through measures in the industrial (IPPU) sector. Tonga commits to a 30 percent reduction in HFC imports by 2035, consistent with the Kigali Amendment to the Montreal Protocol. Measures include establishing a centralized IPPU emissions database, implementing customs-based reporting and quotas, and transitioning to low-GWP refrigerants. Tunisia Tunisia’s preliminary NDC includes methane, nitrous oxide and HFCs in its overall mitigation target. It includes methane measures in the waste and agriculture sectors, such as improved management and treatment systems, and productivity improvements and sustainable land use respectively. Tuvalu Tuvalu’s overall mitigation target covers methane and nitrous oxide. In addition the target covers tropospheric ozone precursors carbon monoxide (CO), nitrogen oxides (NOx) and non-methane volatile organic compounds (NMVOCs) as well as sulphur dioxide (SO2). Methane emissions are addressed through measures including: biogas and waste-to-energy systems, manure management, and scaling up domestic biogas digesters for livestock and piggery waste. Waste-sector measures include composting programs, recycling, hazardous-waste management, and exploring e-waste and circular-economy opportunities to reduce methane and co-pollutant emissions. Vanuatu Vanuatu includes methane and nitrous oxide in its overall mitigation target, covering the energy, transport, agriculture, waste and industrial sectors.Methane is addressed primarily through measures in the agriculture and waste sectors. In agriculture, actions focus on reducing enteric and manure emissions through improved livestock productivity, rotational grazing, and agroforestry and silvo-pastoral systems that enhance carbon sinks and lower methane intensity. In the waste sector, methane abatement is targeted through expanded composting, anaerobic biodigesters, improved landfill management, and waste diversion from open burning and disposal sites. Zambia The provisional NDC of Zambia commits to reducing greenhouse gas emissions by 25% unconditionally, and 47% conditionally compared to a business as usual scenario. These targets are overall greenhouse gas reduction targets, but methane, hydrofluorocarbons and nitrous oxide are considered within the scope of these targets, alongside other greenhouse gases like carbon dioxide. The inclusion of Short-Lived Climate Pollutants like methane and HFCs that are also GHGs, as well as nitrous oxide, within the scope of a NDC greenhouse gas target is an important starting point to action on Short-Lived Climate Pollutants. It means that the Government is incentivised to implement actions to reduce these SLCPs, because their reduction will contribute to achieving their climate change mitigation commitment. Zambia is a net carbon sink, because of the carbon its forests and other vegetation sequesters every year. When these sinks are excluded, 63% of the remaining GHG emissions are methane. Reducing methane therefore needs to be a key component of its climate change mitigation strategy if it is to achieve the greenhouse gas reduction target it has set.
