So, what can you do about it? Carbon Footprint offers a number of carbon offset options from a variety of different projects – and for a variety of different prices. For £12.90, for example, you can pay to have trees planted in a UK region of your choice, or for £9.50, you can support a reforestation project in Kenya.

Other carbon offset organisations allow you to donate to projects which provide efficient cooking stoves to women in Kenya, or offset your emissions by helping small farms in Nicaragua with reforestation.

However, carbon offsetting does not fix the problem. In fact, it’s more of a plaster for the time being: the UN Environment programme supports carbon offsets as a “temporary measure” until 2030, and stresses that we must continue to transition away from carbon as much as possible, by “embracing renewable energy, eating less meat and wasting less food”.
