Växjö (Veck-quwere) is half way to becoming a city free from the use of fossil fuels. An incredible 51% of its energy comes from sources such as biomass, renewable electricity, and solar. In little over a decade emissions have been reduced by 30% per person to 3. 232 tons of CO2 annually - well below the European (8 CO2t/a) and world (4 CO2t/a) averages. The city has made this happen through rigorous planning and by closely measuring all CO2 emissions. With this track record the City may well be the world's first fossil free city.
