Current Projects

2007 Inventory & Projections

MARAMA is coordinating the development of regional emissions inventories for air quality modeling. The inventory includes emissions from Connecticut, Delaware, the District of Columbia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Virginia. Data and documentation related to the inventory are posted for stakeholder review as they become available.

Previous Projects

2002 Inventory & Projections

The 2002 regional emissions inventory was developed for use in air quality modeling to develop state implementation plans (SIPs) for mitigating regional haze. The 2002 inventory was the basis for projecting emissions for the years 2009, 2012, and 2018. These emissions inventories were also used in conducting modeling for ozone and fine particle pollution. Version 3 of the MANE-VU 2002 Emissions Inventory was finalized in 2006 and the projection inventories were finalized in 2007.
