New Hampshire: Emissions and Emissions Reduction Targets

SOURCE: ENE analysis using EPA State Inventory Tool and State Greenhouse Gas Emissions Targets

This chart shows state emissions trends (historical and projected) and emissions reduction targets, offering a picture of New Hampshire’s progress to date.

This chart shows total greenhouse gas emissions by sector, and tracks emissions trends in New Hampshire from 1990 through 2010.

This chart presents New Hampshire’s generation mix in 2001 and 2011, and clearly illustrates a shift toward natural gas and away from coal and nuclear.

Total state emissions and transportation sector emissions have remained relatively constant over the last decade, whereas most northeastern states saw declining total emissions during this time.

This chart compares motor gasoline emissions to forest sequestration in 2000 and 2010 to demonstrate how forests can offset emissions in other sectors.

All eight northeastern states have emissions reduction targets. In order to compare emissions trends with long-term targets, ENE extended EPA State Inventory Tool emissions projections out to 2050. According to ENE analysis and inventory data, New Hampshire is not on track to meet its 2050 target if current emissions trends continue.

As part of ClimateVision 2020, ENE completed comprehensive greenhouse gas inventories for the eight northeastern states. New Hampshire’s total emissions peaked around 2004, but have declined in recent years. New Hampshire’s in-state generation portfolio has shifted over the last decade. The power plant mix today relies less on petroleum and coal than ten years ago, and natural gas has become a significant part of the portfolio. This shift in generation sources is largely responsible for declining electric power emissions, as seen in the inventory visual above. Unlike other northeastern states, New Hampshire’s total emissions have not dropped in the last decade, as the reductions in carbon intensity of electric generation have been offset by a nearly 50% increase in generation. This increased generation resulted in increased exports of electricity to other states.

The carbon dioxide removed and stored by forests each year fluctuates according to harvest practices and changes in land use. New Hampshire’s large forested land base means it has been a steady source of carbon removal.  In 2010, forests offset close to 150% of motor gasoline emissions in the state.
