Question 1

What does "Buffer Pool" mean in the carbon market?

Accepted Answer

Reserve of carbon credits set aside to cover potential reversals or overestimation in carbon projects. Provides insurance against project risks and uncertainties. Buffer pools are the market’s insurance policy: a share of every issuance is set aside in a communal reserve, and if a project reverses through a fire, a flood, or a failure, credits are cancelled from the buffer to keep claims whole. When comparing projects with reversal risk, check how large the buffer contribution is and whether the registry’s pool has historically covered losses.
