Revises requirements for certain greenhouse gas emissions monitoring and reporting activities.

S 3737 revises New Jersey's greenhouse gas emissions monitoring and reporting rules, primarily affecting the Department of Environmental Protection (DEP) and major emitters like fossil fuel companies, electricity generators, and gas utilities. The bill requires emissions reports to calculate global warming potential using a 20-year time horizon (with 100-year values also reported when needed for federal or international compliance), mandates annual reports published within six months, and expands reporting to include hydrogen and fugitive emissions. It also requires the DEP to contract with satellite monitoring technology and ensures all state agency emissions analyses use a 20-year time horizon. These changes provide more accurate, timely data to track progress toward New Jersey's climate goals, including the 2030 emissions reduction target.
