What does it really mean to work towards a low-carbon, small footprint lifestyle?The carbon footprint is an index indicating the – direct and indirect – greenhouse gas emission of an event, product, company, etc. The bigger your carbon footprint is, the more damaging effect it has on the environment. There are many factors influencing our carbon footprint: the flat/house where we live, the amount of energy we use, the goods we buy, the food we eat, the means of transport we travel with. Obviously, it is best to avoid the emission, i.e. to organise our company life and events with the least possible CO2 emission. If we cannot avoid emissions, there are ways to offset and compensate for them. The most natural way is probably planting trees.
