Carbon Footprint & Tree Offsetting FAQ
Everything you need to know about calculating your emissions, understanding tree absorption rates, and taking meaningful climate action.
On average, a mature tree absorbs about 21 to 22 kg of CO2 per year. Therefore, it takes approximately 45 to 50 trees one year to absorb 1 metric tonne of carbon dioxide. Keep in mind that trees take time to grow and reach their maximum absorption rate.
A typical mature tree absorbs approximately 21 to 22 kilograms (about 48 lbs) of CO2 per year. This rate varies significantly based on the tree species, age, health, climate, and soil conditions. Fast-growing species like pine or eucalyptus may absorb more initially, while hardwoods store carbon more densely over time.
The average carbon footprint for a person in the UK is around 5 to 6 tonnes of CO2 equivalent per year. This is significantly lower than the global average (which includes consumption of imported goods) and much lower than the US average, which is around 14 to 16 tonnes per person.
Newly planted saplings absorb very little CO2 in their first few years. Trees reach their peak carbon sequestration rate when they are mature (typically between 10 to 20 years old). When calculating offsets, it’s important to account for the time it takes for trees to grow and reach their maximum absorption capacity.
The most effective ways to reduce your carbon footprint include: switching to renewable energy providers, improving home insulation, reducing meat and dairy consumption, flying less or choosing direct flights, using public transport or cycling, and buying fewer, longer-lasting products. Reducing emissions at the source is always more effective than offsetting them.
