Agriculture Hub

Addressing major sources of methane and black carbon, while improving productivity

The Agriculture Hub is a voluntary network of governments and key stakeholders working together to reduce the sector's short-lived climate pollutant (SLCP) emissions from livestock, paddy rice cultivation, open burning of agricultural residue, and food loss and waste. 

The Hub supports action in the sector by: 

  • Matching governments, inter- and non-governmental organisations, and private sector actors to tackle SLCPs from every angle 
  • Providing access to technical expertise, advice, and training that are central to successful transformation in the sector 
  • Facilitating the exchange of knowledge and best practices

Opportunities for action

By 2030, agriculture methane emissions need to be reduced by 20-25% to limit warming to 1.5°C.

The agriculture and forestry sectors (including land use change) contribute around 24% of all global greenhouse gas emissions. 


Achieving the Paris Agreement target to limit global temperature rise to 1.5°C will require major transitions in the agriculture sector. Large-scale methane and black carbon emissions reductions can be achieved in the sector and deliver benefits for biodiversity, farmers' livelihoods, and food and water security.

The CCAC aims to drive action in the agriculture sector in line with the IPCC Special Report: Global Warming of 1.5°C and the Global Methane Assessment to reduce global methane emissions by 20-25% and black carbon by 35% by 2030.

 The CCAC is pursuing two main goals for the agriculture sector:

  • By 2030, all CCAC partners collectively ensure that agricultural SLCPs are fully considered in national climate policy and that many countries contribute to achieve the 20-25% methane reduction goal
  • By 2030, the top ten agricultural burning nations commit to eliminate unnecessary agricultural burning, with detailed implementation plans and buy-in at the subnational level

We focus on locally appropriate and technically feasible measures that ensure food security and livelihoods are protected.  

Existing measures to address methane emissions in the agricultural sector can achieve reductions of around 30 million tonnes per year by 2030.  These include paddy rice cultivation (6-9 Mt/yr), livestock enteric fermentation (4-42 Mt/yr), and individual behavioural changes (65-80 Mt/yr).

Reducing black carbon from open burning involves raising awareness of alternative crop residue management and uses for crop residues for frequently burned staple crops (maize, rice, wheat and sugar cane).

Our work also leverages the agricultural sector’s linkages to other climate forcers like fertilizers (N2O) to increase the sector’s contribution to midcentury net-zero climate change mitigation.

Foundations for action

The CCAC follows a set of tailored principles and approaches to achieving its goals. This means we:

  • Consider the national context, examining national production and consumption trends, and stakeholders
  • Involve stakeholders at all levels, including small-scale farmers, indigenous peoples, women, and local communities
  • Ensure current goals and policies are streamlined with other relevant plans and sustainable development policies
  • Support regional approaches and knowledge exchange
  • Collaborate with other initiatives on research and innovation, policy and practice implementation, and technical support and capacity


The Agriculture Hub is co-led by Costa Rica, United States, Brazil, and Vietnam. Co-leadership by countries ensures government engagement and ownership of the solutions. Co-leads provide valuable insights into the policy process to help ensure implementation is practical from a national perspective.

The Agriculture Leadership Group consists of both state and non-state members that provide guidance and expertise, and connect the Hub to activities underway beyond the CCAC.
