Designing an effective incentive scheme for climate change mitigation in energy forests

Area of Science:

• Forestry science
• Environmental economics
• Climate change mitigation

Background:

• Energy forests are vital for carbon sequestration and biodiesel production, crucial for climate change mitigation and energy security.
• Current incentive schemes for private forest owners are inefficient due to short durations and lack of consideration for forest heterogeneity, leading to suboptimal budget use.
• Private forest owners' heterogeneity significantly impacts forest management decisions and their contribution to climate goals.

Purpose of the Study:

• To introduce and evaluate an innovative "carrot and stick" incentive scheme for energy forests.
• To optimize carbon sequestration and biodiesel production by private forest owners through integrated subsidies and taxation.
• To account for soil quality and forest heterogeneity in incentive design for sustainable forest management.

Main Methods:

• Integration of the social carbon price concept and a principal-agent mechanism into the Land Expectation Value model.
• Development of a unified framework combining subsidies and taxation for private forest owners.
• Empirical analysis using data from Pistacia chinensis forests to assess the scheme's impact on rotation ages and carbon emissions.

Main Results:

• The proposed "carrot and stick" scheme effectively extends optimal rotation ages, particularly for forests on low-quality soils.
• Tailored subsidies, reflecting forest heterogeneity, further prolong rotation ages, though they may increase government information rent payments.
• Taxation component ensures alignment between sustainable forest management, biodiesel utilization, and carbon neutrality objectives.

Conclusions:

• The developed incentive scheme provides a more effective approach to managing energy forests for climate benefits.
• Policymakers can utilize this framework to design targeted incentives that promote sustainable practices and enhance forest contributions to climate change mitigation.
• Accounting for soil quality and owner heterogeneity is crucial for maximizing the environmental and economic benefits of energy forests.
