TCI webinar on ensuring environmental justice and equity in a regional low-carbon transportation program
Tuesday, September 29, 2020, 4 - 6 PM

This webinar will focus on proposed measures intended to ensure the program fosters equity for overburdened and underserved communities, building on states’ longstanding commitment to designing a program that benefits all communities, including those on the frontlines of air pollution and climate change impacts. The COVID-19 pandemic has highlighted the fact that racial disparities in exposure to air pollution are reflected in disproportionate impacts of the coronavirus and other health threats. The TCI jurisdictions have received extensive input from a wide range of interested people and organizations on ways states could design and implement a regional low-carbon transportation program that advances equity and environmental justice. Informed by that input and further outreach, TCI state officials will provide updates on proposed strategies to ensure that overburdened and underserved communities benefit from investments and reduced air pollution and have opportunities for meaningful engagement in shaping TCI commitments and implementation moving forward. Details and registration information for the September 29 webinar will be available soon on the TCI website. Please RSVP using the link below so we can notify you when the registration link is available.

Updates on the TCI Regional Policy Development Process

May 15, 2020 -- In light of the unprecedented need for governors and agencies to respond to the impacts of the COVID-19 pandemic, the Transportation and Climate Initiative jurisdictions have shared an adjusted timeline for developing a regional clean transportation program.

Under the revised schedule, a final Memorandum of Understanding is now expected in the fall of 2020, at which point, each jurisdiction will decide whether to sign the MOU and participate in the regional program. The timing for signing the MOU has shifted to the fall, but work on the program details continues and engagement with stakeholders will continue to inform the process.

Over the next several months, TCI jurisdictions together will be working on:

  • Identifying investments, initiatives, and complementary policies that will further reduce pollution, benefit public health, create jobs, and accelerate economic recovery in the wake of the pandemic.
  • Economic and public health modeling to analyze how emissions reductions and investments in low-carbon transportation infrastructure will benefit people, businesses, and communities, particularly communities already bearing disproportionate impacts from pollution and lack of access to economic opportunities.

States continue to work on developing a draft Model Rule to release for public input following the final MOU.

Regional Proposal for Clean Transportation Reaches Milestone

States and D.C. invite feedback on Draft MOU, share estimates of potential benefits for health, environment, economy

December 17, 2019 -- The bipartisan group of Northeast and Mid-Atlantic jurisdictions that make up the Transportation and Climate Initiative (TCI) today invited public input on a new draft proposal for a regional program to establish a cap on global warming pollution from transportation fuels and invest millions annually to achieve additional benefits through reduced emissions, cleaner transportation, healthier communities, and more resilient infrastructure.

The draft “Memorandum of Understanding” (Draft MOU) released today builds on a program framework made public on October 1, 2019. A final MOU is expected in the Spring of 2020, following additional public input and analysis. At that time each of the 12 TCI states and the District of Columbia will decide whether to sign the final MOU and participate in the regional program, which could be operational by 2022.

People and organizations provided extensive feedback on the earlier draft framework in more than 1,200 submissions to TCI’s online portal, as well as in public engagement sessions organized in individual states. The Draft MOU released today has been informed by that input and incorporates additional details on the goals and mechanics of such a program.

TCI jurisdictions are also sharing initial projections of the potential economic and public health benefits such a program would unlock region-wide. The TCI jurisdictions have conducted economic modeling to evaluate various options for a program that caps and reduces global-warming carbon dioxide pollution from combustion of gasoline and on-road diesel fuel by up to 25 percent compared to 2022 levels over 10 years.

The transportation sector is currently responsible for more than 40 percent of climate-changing greenhouse gas emissions in the region, and soot and smog from cars and trucks are major contributors to lung disease and other health problems region-wide, particularly in low income communities. Preliminary modeling estimates that by 2032, the proposed program could yield monetized annual public health benefits of as much as $10 billion, including over 1,000 fewer premature deaths, and over 1,300 fewer asthma symptoms annually region-wide, among other safety and health benefits.

The associated auction of pollution allowances under the proposal is projected to generate up to nearly $7 billion annually that participating jurisdictions could invest in solutions to further reduce pollution and to improve transportation choices for rural, urban and suburban communities. Each participating jurisdiction will decide how to invest the auction proceeds to support TCI program goals.

TCI jurisdictions encourage people, companies, organizations, and communities to provide their input on the modeling findings and draft MOU to inform the final program design. Feedback is welcomed on all aspects of a potential program, and TCI jurisdictions are highlighting specific topics on which public input is of particular interest. Those topics include:

  • What factors should TCI jurisdictions consider when setting the starting level and the trajectory for a regional cap on carbon dioxide emissions from transportation fuels?
  • How should the compliance period be structured to provide needed flexibility, while ensuring environmental integrity?
  • What factors should TCI jurisdictions consider when designing mechanisms for managing uncertainty regarding future emissions and allowance prices?

Read the full Draft MOU

All interested parties are asked to provide their input by Friday, February 28, 2020.

The Transportation and Climate Initiative hosted a public webinar on December 17 to share the latest updates in the TCI regional low-carbon transportation policy development process.

Framework for a draft regional policy

October 1, 2019  – Jurisdictions participating in the Transportation and Climate Initiative (TCI) made available a framework for a draft regional policy proposal to reduce greenhouse gas pollution from transportation, and encouraged interested individuals and organizations to provide feedback on the draft framework through the TCI portal. This high-level framework represents an important milestone in the jurisdictions’ bipartisan regional collaboration this year, and reflects extensive public engagement, technical analysis and consultation.

Program Modeling Update
A range of modeling tools are being used to help inform decisions by TCI jurisdictions regarding the design of a regional cap-and-invest program and to provide a fuller picture of the potential benefits and costs of different program design options. While information about the modeling strategy has been shared with the public during TCI webinars held in May and July of this year, a written description with additional details is available. 

Summary of Public Input, January - October 2019 
This is a high-level summary of the extensive input people and organizations have submitted through regional workshops and webinars from January to October 2019. Since the beginning of 2019, TCI jurisdictions have conducted three regional workshops and several webinars, and continue to encourage interested people and organizations to submit input and ideas online. In addition, individual TCI jurisdictions are continuing to offer public workshops and other opportunities for people to participate in the policy development process.

About TCI's regional low-carbon transportation policy design process 

Transportation and Climate Initiative (TCI) jurisdictions are developing a regional policy for low-carbon transportation following the December 18, 2018 statement by nine states and Washington DC committing to:

“…design a regional low-carbon transportation policy proposal that would cap and reduce carbon emissions from the combustion of transportation fuels through a cap-and-invest program or other pricing mechanism… [and]… to complete the policy development process within one year, after which each jurisdiction will decide whether to adopt and implement the policy.”

TCI jurisdictions have designed a workplan with the goal of developing a policy that accelerates the transition to a low-carbon transportation future and delivers a better, cleaner, more resilient transportation system that benefits all our communities, particularly those underserved by current transportation options and disproportionately burdened by pollution, while making significant reductions in greenhouse gases and other harmful air pollution across the region. With ongoing facilitation support from the Georgetown Climate Center, TCI states are planning and beginning to implement a range of activities to ensure that the final proposed policy reflects further input from stakeholders, rigorous technical analysis, and consultation with leading experts.

For additional background, see the TCI Regional Policy Design Process Fact Sheet and the Cap-and-Invest Fact Sheet. Both documents are available in English, Spanish, Portugese, Chinese, and Haitian Creole.

Public workshops 

TCI has hosted three regional workshops this year to explore issues that will be central to the design of a proposed regional low-carbon transportation policy. These events are important opportunities for TCI jurisdictions to consult with experts, businesses, residents, and communities who might inform the policy. In-person workshops are supplemented by topical webinars and ongoing state outreach to constituents within their respective jurisdictions.
