The tax status of carbon offsetting measures will depend on the extent to which they are used to generate profit, says Angus Bauer

We have all been offered the chance to do our bit in the fight against climate change by participating in carbon offset schemes sold by airlines and other organisations. But few of us are aware of what actually happens to the money we hand over, or the size of the market for carbon offset trading. Current estimates suggest that carbon offset trading in the UK alone is worth £50m.
