By working out your monthly footprint below you will see the number of trees required to offset your carbon footprint this year.

Notes;

1. Wood is carbon nuetral. This means that although wood emitts C02 on combustion this C02 was already taken out of the atmosphere when growing.
2. If you are flatting, work these out for yourself and then divide the power and heating sections by the number of flatmates.
3. One newspaper weighs about 0.3 kgs while a ream (500 sheets) of standard A4 paper weighs about 2.5kg.
