CO2 emissions

What is a tonne of CO2 and how can we cut our CO2 emissions?

We often hear about CO2 emissions and carbon offsetting in relation to global warming. We also know that each person in Switzerland generates nearly 5 tonnes of CO2 every year. But what exactly constitutes a tonne of CO2, how do these emissions come about, and what can we do in our daily lives to cut CO2 emissions? Our information and tips are designed to give you a better grasp of this topic.

Switzerland aims to halve CO2 emissions by 2030 compared with 1990 and to be carbon neutral by 2050. By changing our consumer habits and our behaviour, we can reduce our personal carbon footprint and help achieve the Swiss goal. In collaboration with enerjoy, we offer you tips on various aspects of life. Let’s make a difference together on a small scale.

Tips on day-to-day mobility and travel

CO2 fact check: transport

When does travelling use up a tonne of CO2? We have compared four selected modes of transport. A return trip to Cyprus generates around a tonne of CO2, whereas a return trip on the TGV from Zurich to Paris only generates 4 kg of CO2.

Tips on living and energy

CO2 fact check: living and energy

What constitutes a tonne of CO2 for a household? We take a look at heating and electricity usage. It takes an average of a tonne of CO2 a year to heat a 1.5-room apartment. For a single-family home with an oil-fired heating system, however, the figure is five times that.
