Georgetown Law


The Georgetown Climate Center works with state and federal officials and other stakeholders to help bridge any policy gaps that emerge between transportation and climate policy. The Center also assists states in forging ahead with the deployment of infrastructure for electric and clean fuel vehicles, freight efficiency planning, and transportation policies that reinforce the development and maintenance of sustainable communities.

One of the Center's biggest projects is the facilitation of the Transportation and Climate Initiative - a collaboration of 11 Northeast and Mid-Atlantic states plus the District of Columbia.

Vicki Arroyo delivered a TED-style talk at a March 31 event hosted by the Inter-American Development Bank (IDB) to share perspectives on the science, risks, and opportunities for developing sustainable infrastructure as communities prepare for Climate Change.

Arroyo was joined by Gavin Schmidt, a climatologist, climate modeler, and director of the NASA Goddard Institute for Space Studies, and Monica Araya, director of Costa Rica Limpia and founder of Think Tank Nivela.



As the world prepares for international climate negotiations in Paris later this month, six northeast and mid-Atlantic jurisdictions are announcing today that they will work together to develop potential market-based policies to achieve significant reductions in greenhouse gas emissions and other pollution from the transportation sector.  Developing such policies will build on the momentum created by the participating states’ successful clean energy programs and will create positive economic benefits, in addition to reducing the emissions that cause climate change according to a new study released today.


Joint Statement from Connecticut, Delaware, the District of Columbia,
New York, Rhode Island, and Vermont:

(Released 11/24/2015)

Our states are committed to addressing the critical challenge of climate change, which is already affecting our states and communities. To meet this challenge, we will need to achieve significant reductions in greenhouse gas emissions from all sectors of our economy. Our states have already made significant progress, but more work needs to be done.

Since 2010, our states have been working together through the Transportation and Climate Initiative to develop the clean energy economy and reduce greenhouse gas emissions in the transportation sector. The TCI has developed into a robust...

On July 15, Governor Jack A. Markell and the Delaware Division of Energy and Climate announced the Clean Transportation Incentive Programs (CTIP) intended to encourage wider use and adoption of electric vehicles (EVs) and cleaner alternative fuel programs.

The CTIPs include five programs (detailed below) covering a range of clean transportation activities, including rebates for electric and alternative fuel vehicle purchases, rebates for charging stations, grants for electric vehicle charging infrastructure, and grants for innovative transportation solutions designed to reduce greenhouse gas emissions.  

Funded through Delaware’s participation in the Regional...

On June 19, federal agencies proposed new greenhouse gas (GHG) emissions and fuel efficiency standards for medium- and heavy-duty vehicles that are projected to improve tractor trailer fuel economy by as much as 24% in 2027. This second round of truck standards, proposed jointly by the Environmental Protection Agency (EPA) and the National Highway Transportation Safety Administration (NHTSA), will apply to new combination tractors and trailers, heavy-duty trucks, and vocational vehicles for model years (MY) 2019 through 2027.

The proposed standards build upon a previous round of fuel economy and GHG standards that the agencies released in 2011 for MY 2014-2018 vehicles. These previous standards...

Five years ago, 11 northeast and mid-Atlantic states and the District of Columbia launched the Transportation and Climate Initiative (TCI) to develop the clean energy economy and reduce energy use and emissions from the transportation sector.

The initiative is facilitated by the Georgetown Climate Center and led by state transportation, environment, and energy officials in TCI jurisdictions, who gathered this week to celebrate the Initiative’s success during the Northeast Association of State Transportation Officials conference in...
