How Can States Set ‘Blue Carbon’ Baselines to Help Meet Their Climate Goals?

As awareness grows of the important contributions of “blue carbon” habitats—such as salt marsh, tidal forested wetlands, and seagrass beds—in sequestering carbon and reducing climate change impacts, states are beginning to incorporate these coastal ecosystems into their strategies for reducing emissions and enhancing carbon storage through improved management of natural and working lands.

A first step of this work is understanding how much carbon is already being sequestered and stored in states’ coastal habitats. Greenhouse gas (GHG) inventories for coastal wetlands are a key tool that states can use to improve this understanding and provide a baseline for maintaining and expanding blue carbon resources in support of their climate goals.

To help states that are interested in developing blue carbon inventories, The Pew Charitable Trusts hosted a webinar focusing on newly available information from the Inventory of U.S. Greenhouse Gas Emissions and Sinks. The webinar featured representatives from the U.S. Environmental Protection Agency and Silvestrum Climate Associates, and showcased how Oregon used this new federal data source to develop its own state-specific GHG inventory for coastal wetlands.

This webinar was the first in a series of resources that Pew plans to provide as part of its Blue Carbon Network, which launched in February to help create stronger connections among state agencies, practitioners, researchers, and nongovernmental organizations working on blue carbon.
