  • EPA Proposes First Ever CO2 Standards for Commercial Aircraft

    July 22, 2020
    The EPA today proposed first-ever greenhouse gas emission standards for certain new commercial airplanes, including all large passenger jets. The proposed standards, which phase in during 2023-2028, “match the international airplane carbon dioxide (CO2) standards adopted by the International Civil Aviation Organization (ICAO) in 2017,” EPA explains.
  • EPA Proposes First-Ever Aircraft Greenhouse Gas Limits

    July 22, 2020
    Today, the EPA proposed the first-ever limits on greenhouse gas emissions from commercial aircraft engines. Although it is unusual for the Trump administration to push for a new greenhouse gas standard, the bigger issue is whether this standard will be made more stringent in the future. Additional compliance costs would fall on an airline industry that need years to recover from coronavirus-related damage.
  • House Select Committee Climate Report A Pre-COVID-19 Time Capsule

    July 8, 2020
    On June 30, the House Select Committee on the Climate Crisis released its report. There is little original in the report. Most of its sweeping and costly climate policy recommendations have been around for decades and are very similar to the provisions in last year’s Green New Deal. But one thing is novel, and that is how rapidly the report is becoming outdated in light of COVID-19.
  • Air Conditioning Can Help Fight COVID-19—If Federal Policy Allows It To

    July 2, 2020
    COVID-19 persists into the time of year when most Americans rely on air conditioning, so many are asking whether cranking up the cold air helps or hurts in the fight against spreading the virus. The answer is that air conditioning can provide substantial protection from coronavirus, but we need to make sure that the federal government’s pursuit of energy efficiency and climate change policy is not an impediment.
  • Axios Spins IEA CO2 Report

    June 26, 2020
    Axios Generate on June 26 concludes its first article with a “bonus chart” from the International Energy Agency’s recent report, Global CO2 emissions in 2019. According to Axios, the chart shows that “Europe leads the world in emissions decline.” Not so fast. The European Union contains 27 countries. Which country leads the world in reducing emissions? The United States is undisputed champion.
  • COP-26: U.N Climate Conference Delayed until November 2021

    May 29, 2020
    The United Nations Framework Convention on Climate Change announced on May 29 that its 26th Conference of the Parties, originally scheduled for November 9-19, 2020, has been rescheduled for November 1-12, 2021. The extravaganza will still be hosted by the British government in sunny Glasgow, Scotland.
  • Are "Earth-Friendly" New Refrigerants Toxic?

    May 15, 2020
    Bills have been introduced in both the House and Senate to restrict hydrofluorocarbons (HFCs), the refrigerants currently used in most air conditioning and refrigeration systems. But now, one of the leading substitutes for HFCs has been identified as a potential toxin.
  • Will the IPCC's Sixth Assessment Report Rely on Increasingly Overheated Models?

    May 11, 2020
    In a letter published in Nature, Jiang Zhu and Christopher Poulsen of the University of Michigan and Bette Otto-Bliesner of the National Center for Atmospheric Research caution that models used in the Sixth Assessment Report of the UN Intergovernmental Panel on Climate Change may have unrealistically high equilibrium climate sensitivity estimates. This arcane-sounding issue is a big deal.  
  • EPA Sends Proposed Aircraft GHG Rule to White House for Review

    May 8, 2020
    On May 1, the EPA sent its first-ever proposed rule on aircraft greenhouse gas emissions to OMB for review. Promulgated pursuant to the Clean Air Act, the proposed rule comes at a time when the airlines are struggling badly because of the COVID-19 crisis and can ill afford potentially expensive new obligations.
  • New Study Finds Much More Global Greening than Previously Estimated

    May 1, 2020
    A new study paper on global greening by a team of Australian scientists demonstrates that previous estimates of carbon dioxide-induced global greening since 1900 are too small by a factor of two, that the observed greening in their biophysical model is extremely consistent with what is being measured by satellites.
