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

This bill updates New Jersey's rules for tracking and reporting greenhouse gas emissions. It requires companies in fossil fuel production (like refineries and pipelines), electricity generators (including imported power), and gas utilities to report emissions annually, using a 20-year time horizon for calculating global warming impacts. The reporting must show progress toward state targets: maintaining emissions at 1990 levels by 2020, reducing them 50% from 2006 by 2030, and cutting them 80% by 2050. The Department of Environmental Protection will establish these reporting rules within 18 months.
