About us
Climate change is impacting human lives in a variety of ways. It threatens the essential ingredients of good health – clean air, safe drinking water, food supply, and protection from catastrophic weather conditions.

Each of us is responsible for climate change through our way of life. In particular, CO2 emissions are affected by what we eat, how we transport ourselves, where we live, and the products we buy.

Most of us are aware there are consequences of those lifestyle choices. However, the consequences of each of our individual lifestyle choices are not fully transparent or easy to measure.

We know we should reduce air travel, but we do not know the exact consequence / CO2 footprint of a weekend trip to Barcelona, the impact of becoming vegetarian or flexitarian, or getting an electric car instead of an ICE car. We would like to better understand the impact of these choices and get inspired from like-minded individuals across the globe.

CO2HERO is a movement to better our daily lives.
