Carbon Cost Calculator

Purchase certificates here taking responsibility for your carbon emissions with this carbon calculator.


Carbon Damage Mitigation Certificates are linked to smallholder macadamia trees and fund the smallholder Malawian farmers who plant &maintain the trees for their own food security while the trees produce oxygen &absorb CO2 from the Earth's atmosphere.

Enter emissions from flights, driving and domestic energy consumption &/or an annual amount of CO2. Single or regular payment options are available.

Annual Carbon Footprint ?

We use an average U.K. citizen CO2 emission value of approximately 7 tonnes CO2 per person per year.

For extensive information about carbon footprints see International CO2 emissions (Wikipedia) data.

Carbon values are rounded to the nearest 0.02 tCO2 which caters for the units we use in our allocation to trees.

Single Person

Air Flight Footprint ?

Factors used for calculating flight CO2 cost are between 1.4 and 1.45 tonnes per 10,000 km per person depending on flight distance.

Driving Footprint ?

Vehicle CO2 emissions are calculated from standard petrol/diesel/LPG carbon content and electrical charging CO2 emissions from average data from

Your vehicle fuel economy

Domestic Energy Footprint ?

Approximate emission factors used:
Electricity 0.25 tCO2 / MWh;   Gas 0.25 tCO2 / MWh;   Oil: 0.25 tCO2 / 100 litres
