The document details the financial and environmental impacts of transitioning to clean transportation in Maine. It estimates that a total investment of nearly $27 billion by 2050 would yield nearly $37 billion in returns, resulting in a net benefit of over $9 billion. Key benefits include significant fuel savings, reduced carbon dioxide emissions, and improved local air quality.

The document details the costs and benefits of transitioning New Hampshire's transportation sector to clean technologies by 2050.

Environmentally, the transition is expected to avoid over 63 million metric tons of carbon dioxide and reduce fossil fuel use by more than 6.5 billion gallons by 2050.

The document details the costs and benefits of three technology pathways—fuel efficiency, electrification, and low-carbon fuels—for New Jersey. It projects that by 2050, a total investment of nearly $122 billion will generate over $171 billion in returns, resulting in a cumulative net benefit of almost $50 billion. These transitions are expected to reduce carbon dioxide emissions by 353.6 million metric tons and save nearly 37 billion gallons of fossil-based liquid fuels by 2050.

The document details the financial and environmental impacts of transitioning to clean transportation in New York. It estimates that by 2050, cumulative investments of nearly $218 billion in electrification, efficiency, and low-carbon fuels will yield a net benefit of $80.5 billion, primarily driven by fuel savings and avoided environmental costs.

The document details the economic and environmental impact of transitioning to clean transportation in Rhode Island. It estimates that a total investment of nearly $14 billion by 2050 will yield nearly $19 billion in returns, resulting in a cumulative net benefit of over $5 billion. Key drivers of this transition include vehicle electrification, improved fuel efficiency, and low-carbon fuels, which together are projected to avoid 38.7 million metric tons of CO2 and reduce fossil-based liquid fuel use by 4 billion gallons by 2050.

The document details the costs and benefits of transitioning to clean transportation in Virginia by 2050. It estimates that a total investment of $142.5 billion in electrification, fuel efficiency, and low-carbon fuels will generate a cumulative net benefit of nearly $57 billion, primarily driven by fuel savings and avoided environmental costs, while reducing CO2 emissions by 412.1 million metric tons.

The document details the economic and environmental impact of transitioning to clean transportation in Vermont. It estimates that a total investment of $13.4 billion by 2050 will result in a cumulative net benefit of $4.5 billion, driven primarily by fuel savings and avoided environmental costs, while significantly reducing carbon dioxide emissions.

The document provides an overview of energy storage solutions, highlighting the transition from traditional pumped-storage hydropower to advanced battery technologies like lithium-ion. It details the technical trade-offs between different storage methods, the economic trends driving adoption, and the regulatory environment in the U.S. aimed at increasing grid flexibility and resilience.

The report examines how autonomous vehicles (AVs) could affect the Washington, DC, metro region by 2040, finding that while pooled AVs and transit investments increase job access, AVs generally increase total driving and disproportionately increase congestion in low-income neighborhoods and communities of color.

The document argues that climate change is the greatest health threat of the 21st century, citing specific impacts on Canadians such as respiratory issues from wildfires, heat-related deaths in Quebec, and food insecurity in the Canadian Arctic. It calls for federal action to reduce greenhouse gas emissions, phase out coal and fossil fuel subsidies, and invest in public health resilience and a just transition for workers.

The document examines various energy storage solutions, including pumped-storage hydropower, batteries, and compressed air, highlighting their capacity to mitigate the intermittency of solar and wind power. It details the dominance of pumped-storage hydropower in the U.S. utility-scale market and the rapid growth of lithium-ion batteries. The text also outlines specific state-level storage targets in the U.S. and global projections for storage capacity needed to limit global warming to 2 degrees Celsius.

The Union of Concerned Scientists and Fehr & Peers modeled the impact of automated vehicles (AVs) on the Washington, DC, region for 2040. The findings indicate that while AVs could increase job access if deployed as pooled shared services, they risk significantly increasing total driving and congestion. The report highlights that low-income neighborhoods and communities of color would face disproportionately higher levels of congested driving across all scenarios. To mitigate these risks and prevent increased global warming emissions, the authors recommend prioritizing pooled rides, investing in mass transit modernization, and ensuring a rapid transition to electric vehicles.

The report analyzes the potential impacts of automated vehicles (AVs) on the Washington, DC, metro area, arguing that the best outcomes for equity and environment occur when AVs are electric, pooled, and integrated with robust mass transit. Without such policies, AVs could increase vehicle miles traveled (VMT) by up to 66%, exacerbate congestion in low-income neighborhoods, and undermine public transit.

The report finds that while some progress has been made, the world is not yet on track to achieve the 2020 climate turning point. Progress is uneven across the six milestones, with most outcomes designated as having insufficient or off-track progress, though some areas like shipping and public climate finance are on track.

The policy brief identifies 24 key actions to reduce global greenhouse gas emissions by 2030, noting that implementing 19 specific 'On Track' and 'Scale Up' actions can align the world with a pathway to hold warming below 2°C. Full implementation of all 24 actions, including five 'Need Focus' aggressive measures, could reduce annual global emissions by 19 gigatonnes per year by 2030.

The document details how rising temperatures in Oregon are increasing the frequency and cost of wildfires, reducing mountain snowpack, and causing ocean acidification. It highlights the vulnerability of the state's $48 billion agriculture, forestry, and fishery sectors and recommends a transition to a clean energy economy through carbon pricing and renewable energy adoption.

The document evaluates the world's collective progress toward six climate milestones in energy, transport, land use, industry, infrastructure, and finance. It concludes that while some progress has been made, the global community is generally not on track to achieve the 2020 climate turning point. The report highlights significant data gaps that hinder accurate tracking and urges governments, businesses, and financial institutions to increase ambition and fulfill commitments to reach net zero emissions by 2050.

The report examines how carbon dioxide removal (CDR) and solar radiation modification (SRM) are promoted by fossil fuel interests to justify continued oil, gas, and coal production. It argues that these technologies often rely on fossil fuel by-products or enable enhanced oil recovery, creating a 'moral hazard' that distracts from viable renewable energy transitions.
