Energy Efficiency

End-Use Energy Efficiency offset projects reduce building sector CO2 emissions by reducing on-site combustion of natural gas, oil, or propane for end-use in existing or new commercial or residential building. Eligible new buildings are limited to new buildings that are designed to replace an existing building on the offset project site, or new buildings designed to be zero-net-energy buildings. Emissions reductions are determined based on reductions in reporting period energy use related to eligible Energy Conservation Measures (ECMs), in comparison to baseline energy use for those end uses of building systems targeted by eligible ECMs.

To qualify for the award of CO2 offset allowances, End-Use Energy Efficiency offset projects must reduce CO2 emissions through one or more of the following eligible ECMs:

Multiple prescriptive energy efficiency standards, best-practice design and installation practices, or market penetration rate standards may apply to a project depending on the specific ECMs implemented and the date of project commencement.  Consult state regulations for details.

For more information, please consult state regulations.

Parties evaluating potential offset projects in multiple RGGI States should also consult the Model Rule, which was the basis for the development of individual state regulations.  Note that the Model Rule is provided for informational purposes only, and state regulations apply.
