Carbon Credit Buffer Pool Simulator

Voluntary carbon markets (VCS, Gold Standard) don't just measure how much CO2 a forestry project sequesters — they insure the credits they issue against the risk that the carbon goes back up in smoke. This simulator grows a portfolio of forest projects on a real Chapman–Richards biomass curve, withholds a configurable share of each year's sequestration into a shared, pooled non-permanence buffer, and then rolls the dice on reversal events (fire, drought, disease) that can strike one project or, with correlated regional risk, several at once. Watch whether the pooled reserve stays solvent as you tune the buffer contribution rate, per-project risk, and correlation — the exact mechanism that lets a voluntary-market credit keep meaning "one tonne of CO2, permanently avoided" even when individual projects fail.
