This week : calculating our CO2 emissions

Text by Regane RANUCCI

Latest update : 2009-09-21

ENVIRONMENT looks into greenhouse gas emissions. In our daily lives we produce carbon dioxide, we contribute to heating up the planet and we leave what is called a carbon footprint.

Using our car, taking a shower, eating lunch for example leave an impact on the environment. 2 sectors are particularly concerned : agriculture and transportation.

A car emits up to 100 times more carbon dioxide than a bike. When it is made, transporting the oil it needs to the pump and when the car uses up this oil. A bike only emits CO2 when it is made. Manufacturing environmentally friendly vehicles is the latest challenge for car makers. ENVIRONMENT goes to the motor show in Frankfurt.

France has followed the example of Denmark and Sweden. In 2010, the French will pay a carbon tax on oil, natural gas and coal. This measure is supposed to encourage people to use less fossile fuel. ENVIRONMENT sees how it works.

And a town in Belgium has taken an original initiative to significantly reduce the populations carbon footprint. Residents have decided to eat vegetarian one day per week because cattle breading releases a great deal of CO2. Agriculture is responsible for a quarter of global gas emissions.
