Offsetting my carbon footprint for flying to Sierra Leone this summer cost me about £10, but I feel better for having done it.
Carbon offsets are a form of trade. When you buy an offset, you fund projects that reduce greenhouse gas (GHG) emissions. The projects might restore forests, update power plants and factories or increase the energy efficiency of buildings and transportation. Carbon offsets let you pay to reduce the global GHG total instead of making radical or impossible reductions of your own.
So that’s my carbon footprint reduced!
