When carbon emissions are produced, an equal amount of carbon emissions is sequestered elsewhere. Includes residual compensation


Net zero carbon

Carbon emissions are equal to the emissions sequestered by carbon sinks.


Carbon sink

Carbon negative

Carbon emissions are lower than the emissions sequestered by carbon sinks.

Uusiutuva energia

Renewable energy
