What is a carbon credit?
A carbon credit is a certificate representing one tonne of carbon dioxide equivalent (tCO₂e) that has been kept out of the atmosphere or removed from it. Projects earn credits by reducing emissions (for example, replacing diesel with solar power) or by removing carbon (for example, growing trees or applying biochar to soil).
A credit only exists once an independent verifier has checked the project against a published methodology and a registry has issued it with a unique serial number. When a company uses a credit to count against its own emissions, the credit is retired on the registry so it cannot be sold again.
In India, two kinds of credit matter today: credits issued under international voluntary standards such as Verra and Gold Standard, and Carbon Credit Certificates (CCCs) under India's own Carbon Credit Trading Scheme[2][3].
