Nitrogen fertilization as a source of greenhouse gas emissions

Nitrogen fertilizers are the second largest source of greenhouse gases in Swiss agriculture.

The use of nitrogen fertilizers is the second largest source of greenhouse gas emissions in Switzerland’s agricultural sector. Nitrous oxide, a potent greenhouse gas also known as N2O, is released as a byproduct of the bacterial conversion of nitrogen in agricultural soils, the so-called nitrification and denitrification processes. Further emissions result indirectly from nitrogen lost in the form of ammonia and nitrate through volatilization and leaching.

Modern climate protection in Switzerland’s agricultural sector

Modern additives to fertilizer formulations stabilize the nitrogen in its ammonia form, thereby considerably reducing nitrous oxide emissions. Due to their cost, however, these nitrification inhibitors are rarely deployed in Europe as well as worldwide.

In Switzerland, First Climate operates a unique program to promote the use of climate-friendly fertilizers and help grow their market share. By making climate-friendly fertilizers available at discounted prices, the program will render them more affordable for farmers.

The program makes use of the compensation mechanism established in Switzerland’s CO2-Law. This mechanism allows reductions of greenhouse gas emissions to be certified and transferred to third parties if the underlying project activities meet certain criteria.

Which fertilizers are supported by the program?

At this time, the program is limited to a single product, called ENTEC 26. First Climate launched this program in October 2016 after the Swiss Federal Office of Environment granted the necessary approvals. Further subprograms are currently under development, including for the promotion of nitrification inhibitors used in combination with organic fertilizers (manure).

How can I take advantage of the ENTEC 26 program?

The ENTEC 26 program is targeting Swiss importers of ENTEC 26 as participants. Since October 2016, farmers and other downstream buyers in Switzerland benefit directly from discounted prices for ENTEC 26 without any further ado.
The ENTEC 26 program is financed by the KliK Foundation. Find out more about the KliK Foundation >>
