i4green League is a non-profit organization with a value and mission to educate everyone, that the littlest change in their daily lives can have the biggest impact on the future of the Earth. We have provided a number of “green” calculators, which measure how human behavior affects the world. It is aimed to answer the question that we hear so often: what can I do to fight against climate change if I am not a rocket scientist? Every choice matters. Every one can contribute. Together, we will save our planet.
