SettleUp Earth 

A great organisation doing great things, quick and easy to calculate my carbon footprint and offset it, would definitely recommend.

I offset my carbon each month with Settle Up Earth and receive a really handy update each month with how many trees I've planted. Their newsletter is really interesting and I like the company's focus on other issues apart from environmental ones - like providing jobs for people in developing countries and creating diverse ecosystems.
Also the price is really reasonable considering.

Very well run organisation with an easy to use website. The cause is excellent- I feel like not only am I helping out with the fight against climate change but also having an impact on local communities . The team are very friendly to deal with and always keen to help

Great experience offsetting my carbon with Settle Up Earth. Having looked at the options I decided that they have by far the best portfolio as far as ethics and impact is concerned. Highly recommended!

First of all it's an easy-to-use carbon calculator; with just two minutes you can get a pretty good estimates of your carbon foot print, which you can then choose to offset monthly. The price is very affordable even for a student, and because of the transparency you know exactly how much is used for planting trees.
It also weirdly made me feel good about cycling and being on a plant-based diet. Paying less than average to be carbon neutral never felt more rewarding.
