The Presidential Climate Action Plan has assembled several of the roadmaps governments and stakeholders have created in recent years for the world to achieve a net-zero energy economy by 2050 – a key goal of the Paris climate accord. Each entry includes hyperlinks to the full documents shown here. Overall, this roadmap library illustrates there are plausible paths to a cleaner and more stable future, if we have the political will to embark on them. PCAP will continue expanding the list to include other existing and newly released roadmaps.

The Long Term Strategy of the United States

The White House has issued its long-term strategy for the United States to achieve a net-zero carbon economy by 2050. That goal requires actions by every sector of the economy, it says. “There will be many challenges on our path to net-zero that will require us to marshal all our ingenuity and dedication. But it can and must be done.”

Accelerating Decarbonization of the U.S. Energy System (2021)

The world is transforming its energy system from one dominated by fossil fuel combustion to one with net-zero emissions of carbon dioxide (CO2), the primary anthropogenic greenhouse gas. This energy transition is critical to mitigating climate change, protecting human health, and revitalizing the U.S. economy. To help policymakers, businesses, communities, and the public better understand what a net-zero transition would mean for the United States, the National Academies of Sciences, Engineering and Medicine convened a committee of experts to investigate how the U.S. could best decarbonize its transportation, electricity, buildings, and industrial sectors.

Net Zero by 2050

In  2021, the International Energy Agency (IEA) issued this updated version in 2022 to reflect changing circumstances caused by the COVID pandemic and the subsequent world energy crisis. IEA called its document “the world’s first comprehensive study of how to transition to a net zero energy system by 2050 while ensuring stable and affordable energy supplies, providing universal energy access, and enabling robust economic growth.” In addition to charting a path to that future, the document explores key uncertainties like the roles of  bioenergy, carbon capture and behavioral changes in reaching net zero.

Opportunities to Accelerate Nature-Based Solutions: A Roadmap for Climate Progress, Thriving Nature, Equity, & Prosperity

Most roadmaps to zero-carbon futures focus on clean-energy technologies. This one focuses on nature-based solutions to climate change. It was issued by the White House following President Biden’s executive order on restoring forests, protecting coasts and marine ecosystems, reducing flooding, protecting biodiversity, and taking other nature-based steps to address climate change and its impacts. The roadmaps contains “compelling evidence that nature-based solutions are innovative, and that they are highly complementary to necessary technological solutions.” It makes the point that “Nature-based solutions and technology can be powerful allies” and “the climate crisis demands that we deploy all available, proven, science- and evidence-based solutions.”

 

The U.S. National Blueprint for Transportation Decarbonization

The U.S. Department of Energy signed an agreement with other federal agencies in 2022 to accelerate the decarbonization of the transportation sector. The agencies developed this blueprint and described it as a “comprehensive strategy for decarbonizing the transportation sector that will help guide future policy decisions, as well as research, development, demonstration, and deployment in the public and private sectors.”

Roadmap to Reaching Zero Embodied Carbon in US Federal Building Projects

The U.S. government is the largest single purchaser of building construction materials in the United States. The Rocky Mountain Institute developed this roadmap on how the government can reduce the cradle-to-grave embodied carbon emissions in public building projects over the next 30 years. It also contains recommendations on how the government can facilitate a larger movement to decarbonize the building industry and industrial supply chains.

House Select Committee on the Climate Crisis

Former Speaker of the House Nancy Pelosi created a House Select Committee on the Climate Crisis during the 116th Congress to recommend how Congress can “enable an inclusive net-zero economy” by 2050. The Committee’s report, based on public hearings, recommendations from the public, and inputs from other congressional panels, contains a comprehensive set of goals and legislative proposals to achieve them.

Roadmap to Zero Emissions

The urban build environment is responsible for 70 percent of greenhouse gas emissions. Architecture 2030, non-profit non-partisan, think tank, specializes on new approaches to reducing these emissions and how to create adaptive built environments that manage climate impacts, preserve natural resources, and provide access to low-cost renewable water and energy resources. The organization’s Roadmap to Zero Emission addresses actions and financing instruments to keep global warming under 2oC compared to preindustrial levels.

 

 

Roadmap to Carbon Neutrality

The Portland Cement Association says this roadmap would lead to carbon neutrality across the cement and concrete value chain by 2050. The PCA says “This approach to carbon neutrality leverages relationships at each step of the value chain, demonstrating to the world that this industry can address climate change.”

 

A Road Map for a Sustainable Clean Energy Transition During Economic and Geopolitical Uncertainty

This report from the Conference Board lays out a realistic energy transition close plan for the U.S. to achieve net-zero emissions by 2050. While the plan would accelerate the transition to renewable and other zero-carbon energy, it contends that fossil fuels are a necessary energy source that can be part of a net-zero energy strategy.

The Maze of Haze

The journal Science has published research on six models of actions the U.S. could take to reduce greenhouse gas emissions at least 50 percent by 2030. The analysis identifies which findings are more robust or uncertain. It highlights  the central roles of clean electricity and electrification, the large scale of deployment necessary, scenarios based on current policies, and the benefits of near-term action. The research team included specialists from the Electric Power Research Institue, Pacific Northwest National Laboratory, Natural Resources Defense Council, MIT, and the University of Maryland at College Park.

California’s Climate Plan Lays the Roadmap to 2045

The California Air Resources Board (CARB) released this roadmap In November 2022 to propose “the most ambitious climate action of any jurisdiction in the world.” CARB says its plan would achieve carbon neutrality by 2045, cut air pollution by 71%, reduce greenhouse gasses 48% by 2030 and  85% by 2045, lower fossil fuel consumption to less than one-tenth of current use, cut demand for fossil fuels by 86%, create 4 million new jobs, and save Californians $200 billion in health costs due to pollution.

Climate Transition Action Plans

CDP, Ceres, and EDF—members of the We Mean Business Coalition–worked with Ramboll Consulting on this consolidation and analysis of current guidance on the clean energy transition. The Coalition developed a consensus-driven definition of what a comprehensive climate-transition plan should include. Ceres is a nonprofit organization working with the most influential capital market leaders to solve the world’s greatest sustainability challenges. CDP is a not-for-profit charity that runs the global disclosure system for investors, companies, cities, states and regions to manage their environmental impacts. EDF is the Environmental Defense Fund, a U.S.-based nonprofit environmental advocacy group.

Toward a more orderly US energy transition: Six key action areas

McKinsey Sustainability lists six action areas critical for a more orderly energy transition in the United States. Although the actions will probably not be sufficient in themselves, the authors believe they constitute the necessary foundation for the transformation, which should be a high priority today.

Powering Toward 100 Percent Clean Power by 2035

Evergreen Action and the NRDC have produced “A Roadmap to 100% Clean Power,” with recommendations on how the Biden administration and state leaders can build upon the Inflation Reduction Act to achieve 80 percent clean power by 2030 and 100 percent clean electricity by 2035.
