Many people think that if they travel by plane or car on a regular basis then they can cure the carbon emissions they contribute to by doing something green or environmentally friendly.
The truth is that the phrase carbon offsetting means to assist in the funding of an environmental project like a wind farm. This then neutralises the emissions caused by your flight to America, for example.
Carbon offsetting isn’t a cure although it can help, but I suggest you think about what you can do in the first place to reduce the amount of carbon you produce or contribute to. There are many ‘carbon footprint’ calculators that can use to see how you can reduce your output.
