Carbon Sequestration

Interest in terrestrial carbon sequestration has increased in an effort to explore opportunities for climate change mitigation. Carbon sequestration is the process by which atmospheric carbon dioxide is absorbed by trees through photosynthesis and stored as carbon in biomass (trunks, branches, foliage, and roots) and soils. Carbon sequestration in forests and wood products helps offset fossil fuel emissions, one of the key drivers of human-induced climate change.

Sustainable forestry practices can increase the ability of forests to sequester additional atmospheric carbon while enhancing other ecosystem services, such as improved soil and water quality. Planting trees, restoring forested ecosystems, and improving forest health are some of the ways to increase forest carbon. Harvesting and regenerating forests can also result in net carbon sequestration in wood products and new forest growth. Investing in forest carbon sequestration projects is a cost-effective way to complement corporate greenhouse gas reductions or allowance purchases.

In response to government, business, and individual commitments to reduce carbon dioxide emissions, carbon is now a priced environmental asset or commodity in the global marketplace. The United States carbon market is in its formative stages. States and regions are developing climate change strategies and policy for reducing carbon dioxide emissions, and mandatory markets are forming at the regional and state levels. The Voluntary Reporting of Greenhouse Gases Program, established by Section 1605(b) of the Energy Policy Act of 1992, provides a means for organizations and individuals to record their baseline emissions and emission reductions.

Going carbon neutral…

The voluntary “retail” market is growing as more and more individuals and entities seek to purchase carbon offsets to reduce their greenhouse gas footprint or become “carbon neutral.” The voluntary market plays a significant role in climate change mitigation. By allowing the broader public to engage in climate protection, the voluntary market advances societal awareness of climate change and the impacts of consumer behavior. Learn more:
