Carbon offsetting explained in 2 minutes

Carbon offsetting will be a major point of tension at the COP26 climate summit in Glasgow. How does it work and who makes use of it?

Countries participating in the Paris Agreement are expected to update their pledges at the United Nations Climate Change conference that will be held in Scotland between October 31 and November 12. The aim of the agreement is to substantially reduce greenhouse gas emissions in an effort to limit the global temperature increase to well below 2 degrees Celsius above pre-industrial levels.

Countries can become carbon neutral by limiting the amount of greenhouse gases they produce and by compensating the emissions that can't be cut. The carbon offsetting market has become increasingly attractive for countries, companies and individuals, who finance projects that will either suck CO2 out of the atmosphere, or reduce the CO2 release. 

Compulsory versus voluntary compensation

In Switzerland, power stations and companies with high greenhouse gas emissions, such as cement or chemical producers, are obliged to participate in the EU emissions trading system. The companies receive or buy emission allowances, and they can trade them with one another. Medium-sized companies can join the scheme voluntarily.

Carbon offsetting is also available at the individual level. Many platforms - such as the UN Carbon offset platform or - allow people to calculate their carbon footprint and choose to donate to reforestation or renewable energy projects, for example. 

Switzerland's pledge and actions

Switzerland aims to halve its emissions overall by 2030 and become climate neutral by 2050. The government's roadmap covers industry sectors, energy efficiency in buildings as well as investments in projects that reduce the CO2 released into the atmosphere.

Switzerland failed to meet its intermediate goal of reducing emissions to 20% below 1990 levels: It only managed a 14% reduction by 2020. To fulfil obligations under the Paris Agreement, the Swiss government suggested a set of measures. The so-called "CO2 law" is one of them. It was put to a nationwide vote, but rejected in June 2021.

Switzerland has so far signed deals with Peru, Ghana, Senegal, Georgia, Dominica and Vanuatu to offset its carbon emissions. Investments will finance biogas plants, solar panels and geothermic energy, as well as programs aimed at increasing energy efficiency in buildings and electrifying public transport.
