Extended Data Fig. 4: The effects of discount rate and years of growth on carbon costs of harvesting secondary forest in Scenario 1.

This figure includes different carbon cost estimates of harvesting secondary forests not plantations in Scenario 1 varying discount rates from 0% to 6% and discounting over 40 or 100 years. Red (left) bars show discount effects of each year’s harvest on changes in carbon pools for 40 years; Green (right) bars discount these effects on changes for 100 years. Percentage changes are relatively modest except for applying a 0% discount rate over 100 years. These indicate similar valuing of the costs of wood harvest so long as there is even a modest social preference for earlier rather than later mitigation of emissions. Source: CHARM.
