The AVoided Emissions and geneRation Tool (AVERT) evaluates how energy policies and programs such as energy efficiency, renewable energy, and electric vehicles lead to changes in emissions of particulate matter (PM2.5), nitrogen oxides (NOX), sulfur dioxide (SO2), carbon dioxide (CO2), volatile organic compounds (VOCs), and ammonia (NH3) from electric power plants at a county, state, or regional level. AVERT is a free tool designed to meet the needs of state air quality planners, energy officials, public utility commission staff, environmental agency staff, professionals in the clean energy field, people working on climate planning, and other interested stakeholders.
