New modeling using the Nevada Energy Policy Simulator finds the state is off-track for its own climate goals with emissions likely to increase 12 percent by 2050. But strategic building, industry, and transportation sector policies would put Nevada on a 1.5° Celsius pathway, generate 5,500 job-years annually, and increase state GDP by $800 million per year in 2050.
New Energy Policy Simulator modeling shows a small group of policies can achieve the emissions reductions required for a 1.5 degree Celsius pathway, while generating large economic and health benefits. Transforming the economy in line with a 1.5 C target could increase U.S. GDP $1 trillion per year and create 5.5 million new job-years, while avoiding more than 65,000 premature deaths and 2 million asthma attacks, all by 2050.
Accelerated clean energy deployment and ambitious climate policies have created China’s carbon neutral opportunity for economic growth, a lower-cost electricity system, energy security, cleaner air and water, and more sustainable cities. Realizing these benefits hinges on policies including a well-designed price on carbon, clean energy standards, and green finance.
New modeling using the Minnesota Energy Policy Simulator finds a newly proposed clean energy standard would cut statewide emissions nearly 20 percent by 2050, but strategic policies in the building, industry, and transportation sectors would put Minnesota on a 1.5° pathway, generate 39,000 job-years, and increase state GDP by more than $11 billion per year.
This report uses the Energy Policy Simulator to model two illustrative scenarios showing that a ten year-delay implementing climate action putting the U.S. on a net zero path by 2050 increases the cost of decarbonization by nearly three quarters, showing why we must adopt strong carbon emissions reduction policies to avoid catastrophic climate change impacts.
Energy Policy Simulator modeling shows a subset of the policy recommendations issued by the House Select Committee on the Climate Crisis will put the U.S. on pace for net zero carbon dioxide emissions before 2050, while generating nearly $8 trillion in monetized health and climate benefits.
The Trump Administration’s proposed fuel economy standard rollback and emissions standards freeze will harm consumers and the environment. This research note finds the proposal would cost the U.S. economy up to $400 billion through 2050, increase U.S. emissions up to 10%, and gasoline use up to 7.6 billion barrels through 2035. It would also cost Canada up to $70 billion through 2050 and increase its emissions up to 11% by 2035.
Cement manufacturing produces 5.6% of global CO2 emissions. This research finds that capturing 80% of cement’s process emissions (and no thermal emissions) by 2050 can make cement carbon-neutral, as natural carbonation offsets remaining emissions. If thermal fuel supply were fully decarbonized by 2050, a 53% process emissions capture rate achieves carbon-neutral cement. Higher capture rates than these would provide net negative CO2 emissions and the possibility that simply making concrete could reduce atmospheric CO2 concentrations.
UPDATE: We updated this analysis in August 2019 to incorporate newer data and assumptions in a new research note. The Trump Administration’s proposed fuel economy standard rollback and revocation of California’s ability to set vehicle emissions standards will harm consumers and the environment. This research note finds the proposal would cost the U.S. economy up to $457 billion through 2050, while increasing U.S. emissions up to 11% and gasoline use 20% through 2035.
This research paper reviews what it would take to achieve energy system decarbonization, including parts of the energy system that are particularly difficult to decarbonize including aviation, long-distance transport, steel and cement production, and provision of a reliable electricity supply.
