This European survey examines: US regulation of greenhouse gases – including carbon dioxide from motor vehicles and power plants, and methane from oil and gas wells – rests on the Clean Air Act. The Environmental Protection Agency (EPA) recently announced its rescission of the greenhouse gas endangerment finding and motor vehicle greenhouse gas emission standards: https://www.epa.gov/regulations-emissions-vehicles-and-engines/final-rule-rescission-greenhouse-gas-endangerment. The President of the National Academy of Sciences subsequently wrote to the organization's members, noting that 'the EPA justified its decision on legal, economic, and regulatory opinions, and not on the science’. (a) The weight of economic analysis and evidence supports the conclusion that some form of regulation of greenhouse gas emissions is warranted; (b) For US consumers and firms, the health and environmental benefits of greenhouse gas emission standards outweigh the costs, making the EPA rescission substantially net negative for American society; (c) Since the environmental costs of greenhouse gas emissions are globally distributed, some form of collective international regulation is warranted

This European survey examines (a) Adoption of artificial intelligence will lead to a substantial increase in the growth rates of real per capita income in the US and Western Europe over the next ten years; b) Adoption of artificial intelligence will lead to a substantial increase in the unemployment rates in the US and Western Europe over the next ten years

This European survey examines (a) For reducing global greenhouse gas emissions, subsidies for R&D on low-carbon technologies are justified in addition to carbon pricing mechanisms like carbon taxes and cap-and-trade systems; (b) Higher subsidies for R&D on low-carbon technologies are justified by the fact that their successful deployment would not only reduce emissions in OECD countries but also reduce developing countries' emissions by encouraging them to substitute away from fossil fuels

This US survey examines (a) For reducing global greenhouse gas emissions, subsidies for R&D on low-carbon technologies are justified in addition to carbon pricing mechanisms like carbon taxes and cap-and-trade systems; (b) Higher subsidies for R&D on low-carbon energy sources are justified by the fact that their successful deployment would not only reduce emissions but also induce developing countries to substitute away from fossil fuels

This European survey examines The OECD’s projected cumulative emissions of greenhouse gases from today until the year 2100 is 616.2 billion metric tons of CO2e, compared to 2,734 billion metric tons for the rest of the world - 82% of the total. (Larsen et al, Rhodium Group, 2024: https://climateoutlook.rhg.com/reports/rhodium-climate-outlook-2024-probabilistic-global-emissions-and-energy-projections): (a) The domestic net benefits of emissions reductions vary substantially across countries because of differences in income levels and exposure to climate risk; (b) In the absence of incentives from developed countries, developing countries will not reduce their emissions substantially in places where the private costs of fossil fuels remain meaningfully lower than those of zero-carbon fuels; (c) Providing incentives for developing countries to reduce their emissions through penalties (such as a carbon border adjustment mechanism or carbon club) is substantially less effective than providing equivalent incentives through subsidies (such as payments for climate damages in exchange for emissions reductions)

This Finance survey examines (a) Under current policies on climate change, the associated physical risks (such as those arising from total seasonal rainfall and sea level changes, and increased frequency, severity, and correlation of extreme weather events) will be at most a very small factor in monetary policy decisions over the next decade; (b) The physical risks associated with climate change under current policies are likely to threaten financial stability over the next decade

This European survey examines (a) The high cost of electricity for industrial users in the European Union relative to other big economies is a substantial constraint on growth; (b) Problems with the intermittency of renewable energy sources mean that over the next five years, electricity prices are more likely to rise than fall; (c) Substantial European investment in electricity infrastructure is essential to address high prices and unreliable supply

This European survey examines (a) On the basis of current climate policy commitments and potential technology and market responses, my current best estimate for global warming is that average global temperatures by 2100 will rise to no more than 2.5 degrees Celsius above pre-industrial levels
