Building Electrification in Maryland: Implementation of Zero-Emission Heating Equipment Standards for Low-Income Households - Center for Progressive Reform
Maryland has committed to an equitable approach to achieving its ambitious climate goals while minimizing harms or costs placed on historically disadvantaged communities. One of the programs critical to achieving the state’s climate and energy goals as mandated under the Climate Solutions Now Act of 2022 is zero-emission heating equipment standards (ZEHES). Equitable implementation of ZEHES requires low-income households to be able to fully benefit from clean, efficient heating under the program. This report addresses the costs and the benefits of installing heat pumps and how to...
