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.
