The region’s governments area currently reviewing new transportation projects to add to their long-range plan. But the list of projects in the queue, if built, will increase carbon emissions rather than lower them.

Right now, the National Capital Region Transportation Planning Board (TPB) is conducting its annual review of new projects for the Constrained Long Range Plan (CLRP). The CLRP is a comprehensive list of the “regionally significant” transportation projects that TPB member governments realistically believe could be funded over the next few decades.

Projects that Maryland, Virginia, and DC wish to build must go through the CLRP both to be eligible for federal funding, and to go through the federally required air quality conformity process.

Analysis of 2013 Constrained Long Range Plan by TPB staff.

While federal air quality rules require the region’s transportation projects to meet goals for pollutants regulated under the Clean Air Act (Nitrogen Oxide and Volatile Organic Compounds that form ozone, along with particulates (PM2.5)), the TPB does not yet have to regulate carbon dioxide. The transportation projects in the pipeline, if built, would send us far past—that is, in the opposite direction of—our climate change goals.

In 2008, the Metropolitan Washington Council of Governments (MWCOG) set a goal of reducing CO2 emissions 80% by 2050 below 2005 levels. Several initiatives since then have studied ways the transportation sector, which emits 30% of the region’s CO2, could meet the goal. There is the 2010 Region Forward plan, the 2010 “What Would it Take?” report, and the 2014 Regional Transportation Priorities Plan. {….}
