Statewide GHG Emissions Estimates & Projections
- Statewide Greenhouse Gas Emissions Level: 1990 Baseline & 2020 Business As Usual Projection
The GWSA required MassDEP to determine statewide greenhouse gas emissions levels in 1990 and project what they would be in 2020 if no additional measures are imposed to lower them. July 2009.

- Response to Comments on Statewide Greenhouse Gas Emissions Level: 1990 Baseline & 2020 Business as Usual Projection
MassDEP held six public meetings across the state in April and May 2009, held a public hearing on May 19, 2009, and accepted comments until June 1, 2009. A summary of public comments received and the agency's responses is presented here.
