An Econometric Analysis of the Costs of Sequestering Carbon in Forests
用计量经济学土地利用模型估算美国三个州的造林碳汇边际成本，发现造林仍是低成本减排方式，但早期研究低估了成本，且人口变化对成本影响显著。
Abstract The Kyoto Protocol and the U.S. Climate Change Plan recognize afforestation as a potential means of reducing atmospheric CO 2 concentrations. To examine the cost‐effectiveness of afforestation, we use econometric land use models to estimate the marginal costs of carbon sequestration in Maine, South Carolina, and Wisconsin. Our findings include the following: ( a ) earlier studies of afforestation programs tend to underestimate carbon sequestration costs, ( b ) afforestation still appears to be a relatively low‐cost approach to reducing CO 2 concentrations, ( c ) Wisconsin offers the lowest‐cost opportunties for carbon sequestration, and ( d ) projected population changes have the largest effect on costs in South Carolina.
