1 Domestic and International Forestry: Implications for the Carbon Market Ruben N. Lubowski Senior Economist, EDF EPA/RFF Workshop on Modeling the Costs and Volumes of GHG Offsets Washington, DC, May 12, 2009

2 What is the likely impact on GHG allowance prices of allowing forest carbon credits? How many such credits are likely to be available at prevailing prices? What is the profile of those credits over time? How could REDD work in practice? Hypothetical scenario for Brazil.

3 METHODOLOGY Our model solves for an intertemporal equilibrium for the period Two conditions are met in every year: The market clears. The price rises at the market rate of interest. Policy scenario U.S. adopts Waxman-Markey targets: 4% below 1990 by 2020 and 69% below by Group 1 (EU, Japan, Canada, Australia, NZ): 60% below 1990 levels by Group 2: BAU until 2020, steady decrease to 1990 levels by No restrictions on trading.

10 How Could REDD Work? Hypothetical Example based on Brazil Announcement ENVIRONMENTAL DEFENSE FUND

11 ENVIRONMENTAL Cap and DEFENSE Trade FUND Scenario for Brazil * EDF projections. If Brazil and the US trade exclusively through 2020, US could reduce 4-10% below 1990 levels by 2020, rather than reaching 1990 by 2020, at no added cost to US companies compared to no REDD.

12 Summary Forest carbon from developing countries could lower the global allowance price by 12%-32% if deforestation only is included, and by about 16%-45% if all forest carbon is included, depending on realized potential of 25%-100%. Average US purchases over range from billion tons/year if deforestation only is included, and if all forest carbon is included, depending on realized potential of 25%-100%. International forest carbon could be used to induce broader participation in the global carbon market to achieve greater and faster overall reductions for the same cost as a regime without forest carbon.
