There are a lot of factors that impact how much carbon a certain activity generates. 

An online tool can never be 100% accurate but we hope you can use this as a general guideline. 

The amount of carbon absorbed by a tree depends on the tree type, location and life.

Our tree planting partner plants mangroves – one of the most effective and economic methods of offsetting carbon emissions. 

Each mangrove tree removes approximately 0.3 tonnes of CO2 from the atmosphere over its growth life – approximately 25 years.
