Switzerland has a robust national clean air policy and is committed to continue reducing short-lived climate pollutants (SLCPs) at the national level and assist such efforts in its international collaboration. Further, Switzerland is committed to combat climate change at both national and international levels, engaged in the UN Framework Convention on Climate Change and in its Kyoto Protocol. Therefore Switzerland supports the efforts under the Climate and Clean Air Coalition to promote international actions and cooperation on SLCPs.

Domestic Activities

With a total of more than 20,000 retrofitted vehicles and machines, Switzerland has carried out pioneering work to reduce emissions of diesel soot / Black Carbon (BC). Indeed Swiss environmental legislation requires emissions of carcinogen substances to be minimised. To protect the population, the Federal Council (the Executive) initiated an action plan against particulate matter (PM) in 2006, introducing a variety of measures aimed primarily at reducing the high level of soot / BC emissions from diesel engines. While Switzerland requires road vehicles to abide by the exhaust standards of the European Union, in the non-road sector it imposes various more stringent technical requirements for each type of diesel engine wherever workers, nearby residents and passers-by are at risk. The approved particle filter systems on the list published by the Federal Office for the Environment (FOEN) have for years provided a highly-developed technological solution for diesel engines and the abatement of the carcinogenic soot / BC.

Switzerland has introduced already in 2004 strong restrictions for the use of HFCs as well as other synthetic greenhouse gases in all sectors (refrigeration, air conditioning, foams, solvents, spray cans, fire extinction) based on the assessment of availability of climate friendly alternatives and with the purpose of stabilising their emissions. In November 2012, these restrictions have been strengthened particularly in the refrigeration – air conditioning sector as climate friendly alternatives commercial availability has rapidly increased these last years.

International Activities

Switzerland is active at the international level through two agencies, SDC and SECO, that work, where required, in close collaboration with other concerned line ministries. Areas of support include the following:

Black carbon from brick production

Ongoing projects: Energy Efficiency Program in small-scale brick production in Latin America (EELA, Spanish acronym) and the Vertical Shaft Brick Kiln (VSBK) project in South Africa.


Switzerland has gathered since beginning 1990’s significant experience about implementation of climate friendly alternatives to CFCs – HCFCs - HFCs in the refrigeration and air conditioning sector in developing countries, particularly in India and Indonesia.

Air quality and diesel filters

A diesel filter project in China has started and covers diesel filter pilot tests (fix and mobile sources) and supporting the drafting of clean air legislation. In Chile, an air quality and diesel filter project has been completed successfully. A regional project is being planned in Latin America covering Argentina, Colombia and Chile.

Domestic cooking and kerosene lanterns

Switzerland is supporting the Energising Development Partnership (EnDev). EnDev is an impact-oriented initiative of 6 donors. It promotes the supply of modern energy technologies (improved cock stoves, solar lanterns, solar home systems, mini-grids and grid access) to households and small-scale businesses in Africa, Asia and Latin America.


Switzerland supports energy production from organic waste (methane) in developing countries, e.g. under the Resource Efficient and Cleaner Production Program with UNIDO.


The aim of the Heavy-Duty Diesel Initiative of the Climate and Clean Air Coalition is to virtually eliminate black carbon and fine particulate emissions from the on-road vehicle fleet by 2030. The...
