Use the Blue Carbon Calculator

The Blue Carbon Calculator is a first-generation tool to assess GHG impacts of aquatic ecological restoration projects, with a focus on coastal wetlands.

Coastal wetlands capture and bury carbon at high rates. This carbon is called blue carbon. Restored salt marshes are especially capable of sequestering blue carbon and reducing harmful methane emissions. 

Using the Calculator is simple:

1. Enter Expected Land Cover Changes 
The user enters the land area for each type of land cover change resulting from a project.

2. See the Green House Gas Budget
Annual emissions resulting from each change in land cover are calculated based on internationally accepted data. Results appear on the “Calculator” worksheet.

Get Started!

Use the tool below to assess GHG impacts of your aquatic ecological restoration projects. For more information you can read our one-page Fact Sheet or the full report.
