Part of the emission reductions are generated in Switzerland, namely through the operation of biogas plants. These use agricultural farmyard manure such as dung and liquid manure for the production of electricity and heat and at the same time reduce climate-damaging methane emissions. The other part of the portfolio contains emission reduction certificates from a carbon offset project in Brazil. There, forests, not least a supplier of raw materials for the paper industry, are sustainably managed in accordance with FSC guidelines and the wood waste produced is used to generate electricity from renewable raw materials.
By building and operating these two agricultural biogas plants in Switzerland, power and heat are produced and methane emissions are prevented simultaneously. It is very difficult for smaller agricultural biogas plants to become profitable. Only revenues from CO₂ certificates, which are issued in this project for the prevention of methane only, allow the implementation of these agricultural biogas plants and guarantee sustainable and profitable operation. In the project’s biogas plants, animal excrement from farmyards and organic waste from other sources are fermented in a fermentation tank. The thereby produced biogas is converted into power and heat in a combined heat and power plant. The power generated is fed into the grid; the heat is used in the fermentation process of the biogas plant and to heat buildings. Finally, the fermentation residue is distributed as valuable fertiliser on the surrounding fields. But agricultural biogas plants do not only generate renewable energy, they also prevent methane emissions.
In the Brazilian Amazonas region, myclimate supports the switch from diesel to climate-friendly FSC woodchips for the production of electricity. The project replaces several diesel generators and helps to supply the approximately 80,000 inhabitants of the city with climate-friendlier power. For the production of the electricity, around 100,000 tonnes of wood are required annually. These are delivered in the form of wood waste and sawdust from the sawmill. All this wood waste comes from sustainable forestry in accordance with FSC guidelines. Prior to start-up of the plant, this wood waste was rotting in large piles on the property. Through the sustainable use of the waste, a reduction of the greenhouse gas methane was therefore also possible.
