The current year began with the revised Swiss CO₂ Act, which came into force on 1 January 2025. With the Swiss CO₂ Ordinance adopted in April, the Federal Council has brought the implementing provisions of the law into force retroactively from the beginning of the year. The concrete implications this has for the work of the KliK Foundation up to 2030 can be read here.
With a view to the 2030 funding horizon, the application period for some domestic programmes has been closed. Numerous other programmes continue as usual and delivered highlights in 2025: in agriculture, for example, the KliK Foundation, together with its partner Ökostrom Schweiz, supports biogas plants – both large projects, such as EcoBioVal in Courtemelon (JU), and smaller farm fertiliser plants, such as those of the Ruckli brothers in Sins, Aargau.
In the building sector, the KliK Foundation continues to offer attractive supported programmes for sustainable heating solutions with wood or heat pumps in collaboration with Renera AG, and in the area of energy efficiency with the intelligent, AI-based supported programme ECCO2 heating control system, whose application is nicely explained here in a housing estate in Winterthur.
The KliK Foundation and its project partners made significant progress in international mitigation activities, particularly in the last quarter of 2025: Switzerland and the respective partner countries authorised four new activities, which are now being implemented at full speed. These include the first Article 6 activity in Latin America and the Caribbean, in which a Chilean sugar producer will use biomass from wood industry residues instead of fossil fuels as an energy carrier. In Morocco, an activity was authorised that supports to accelerate the adoption of solar energy technologies, thereby promoting the expansion of renewable energies in the country. In Ghana, two clean cooking activities received the green light from partner countries, scaling up the use of both electric cooking stoves and improved cookers in rural areas. The KliK Foundation and its business partners were able to sign 22 new contracts for the purchase of ITMOs, known as Mitigation Outcome Purchase Agreements (MOPAs), in 2025 alone. All mitigation activities already in implementation or in authorisation can be found at klik.ch/activities.
Since early May, Switzerland has concluded bilateral climate agreements with three additional countries: Kenya, Zambia and Mongolia. There are now a total of 16 partner countries in which the KliK Foundation is able to support ambitious climate protection efforts.
Another milestone in international climate action was the first issuance of ITMO credits from Africa. To strengthen understanding of the positive impact of mitigation activities under Article 6 of the Paris Agreement in Switzerland's partner countries, the KliK Foundation has launched a new information page along with a thematic series highlighting selected technologies, regions and sectors. The aim is to provide an evidence-based representation of how the Swiss compensation instrument works, including its effectiveness, quality standards and experiences from partner countries.
