That depends on a number of factors such as age, species and environmental conditions but the most common estimates range between 400-900kg of CO2  captured in a tree’s lifetime. We’ve decided to be cautious in our estimation, using 200 kg as a lifetime estimation for each tree planted. As a result we’re confident that 200 kg is very much on the low side by anyone's measure and at Switch2Zero we don’t want to oversell the potential impact.

Switch2Zero only works with projects that have robust, third-party verified approaches to how they calculate costs and offset equivalencies. Working with partners at The United Nations and Gold Standard means we can trust the figures we’re given and be confident our customers’ contributions go where they’re supposed to. 

We don’t believe it would be responsible or accurate to  count a sapling tree’s future carbon capture when calculating the offset of your footprint in today's terms. While trees do reduce atmospheric carbon dioxide (we’ve conservatively estimated 200kg CO2 in a lifetime), we consider the planting of trees a “pay it forward” gift to the next generation, not just capturing CO2 but encouraging biodiversity and providing an economic boost in the communities that plant and tend them. 

The cost per tonne of CO2e captured or reduced can vary significantly depending on the type and location of the project. Each month, we invest in a range of 8 to 15 different projects, aiming for a balance of project types and geographical locations. This allows us to maintain an average cost of £5.50 per tonne of CO2e. We aim for this average price as it strikes the right balance between offering you consistent monthly costs and investing in a broad portfolio.

For tree planting (£0.37 per tree) and plastic waste collection (£0.60 per kg), the costs are simpler as they remain fixed.

CO₂e is shorthand for Carbon Dioxide Equivalent and it’s used  to measure how much carbon is “offset” by different projects and initiatives. kgCO₂e stands for Kilograms of Carbon Dioxide Equivalent and is used to measure CO₂e.
