The Washington state Department of Ecology (Ecology) has just conducted its first auction of greenhouse gas (GHG) emission allowances, under the state’s Climate Commitment Act (or CCA) which establishes a comprehensive, market-based program to reduce carbon pollution and achieve greenhouse gas limits set in state law. The CCA was one of a package of climate-related laws passed in 2021, including the Clean Fuel Standard, and an expanded hydrofluorocarbons management program. The remainder of this note discusses CCA and the recent sale of GHG allowances.Read More

On January 24, the US Environmental Protection Agency (EPA) published tighter standards for emissions from “heavy-duty” engines and vehicles, beginning with model year 2027. These new standards form the important first step toward implementation of EPA’s Clean Truck Plan, which has the ultimate goal of zero emissions from motor vehicles. The new standards are more than 80% stronger than current standards, which have been in place more than 20 years. These changes therefore continue the recent trend toward tighter federal emission standards for motor vehicles, including light-duty vehicles (automobiles and light trucks; I discussed the latest rules for light-duty vehicles, covering greenhouse gas (GHG) emissions for model years 2023-2026 HERE). The remainder of this note discusses the latest heavy-duty vehicle standards.
On November 10, the Biden Administration announced a proposal to amend the Federal Acquisition Regulation (FAR) to require “major federal suppliers” and “significant federal suppliers” to disclose their greenhouse gas (GHG) emissions and assessments of climate-related risks, and to set targets for GHG emission reductions. The rest of this note summarizes this proposal.Read More
The US Environmental Protection Agency (EPA) continues to expand and refine environmental compliance requirements, including those related to greenhouse gas (GHG) emissions. In particular, facilities and organizations subject to EPA's mandatory GHG emission reporting rules should be preparing to submit reports covering calendar year 2021. The remainder of this note summarizes these requirements.
During the last decade, federal state authorities have sparred with themselves and with states over regulatory standards limiting greenhouse gas (GHG) emissions from automobiles. Nationally, the US Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) share authority over fleetwide and individual vehicle standards. EPA applies authority under the Clean Air act (CAA) and NHTSA applies authority under the Energy Policy and Conservation Act of 1975 (EPCA) including Corporate Average Fuel Economy (CAFÉ) standards. In addition, the state of California has unique CAA authority over vehicle emission; in recent years, Democratic presidential administrations generally produce federal-state cooperation, whereas Republican presidential administrations produce conflicts. (I’ve written about these issues several times, most recently HERE). True to this pattern, on December 21, 2021 EPA issued tighter vehicle emission rules covering Model Years (MY) 2023 through 2026, and NHTSA rescinded its (Trump era) rule preempting California’s stricter GHG emission standards. The remainder of this note discusses these new rules, within the context of ongoing rulemakings.Read More
One of the longest running sub-national greenhouse gas (GHG) control efforts in the U.S. has been the Regional Greenhouse Gas Initiative (RGGI) program. RGGI provides a cap-and-trade program covering GHG emissions from targeted fossil fuel power plants in participating northeastern states. The program is preparing to add a new participating state in 2021 -- Virginia.Read More
After nearly a decade of talking and planning, most of the northeast and middle Atlantic states (plus the District of Columbia) in the Transportation and Climate Initiative (TCI) have proposed a cap-and-trade program intended to reduce greenhouse gas (GHG) emissions from transportation. On October 1, TCI issued a “Framework for a Draft Regional Policy Proposal,” and on December 17 a formal “Draft Memorandum of Understanding (MOU)” that jurisdictions can sign to formalize their participation. If things go well, the formal program should begin in 2020.Read More
The federal government has taken another step in its car wars with California. Late in September the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) issued joint rules declaring NHTSA’s preemptive authority to set national standards covering greenhouse gas (GHG) emissions from petroleum-fueled vehicles and electric vehicles, and revoking a waiver from EPA that lets California set such standards.Read More
On August 23, the federal Court of Appeals for the District of Columbia (DC Circuit) upheld most aspects of the National Ambient Air Quality Standards (NAAQS) for ground level ozone adopted by the Environmental Protection Agency (EPA) in 2015. The Clean Air Act (CAA) requires EPA to create a list of air pollutants based on emissions that cause or contribute to air pollution that may reasonably be anticipated to endanger public health or welfare (criteria pollutants), to establish NAAQS based on these criteria, and to review the NAAQS every 5 years.Read More
The Clean Air Act (CAA) directs the Environmental Protection Agency (EPA) to define “hazardous air pollutants (HAPs)” that may pose acute health hazards, and to impose regulations to reduce those hazards. EPA requires permits for “major sources” of HAPs based on “Maximum Achievable Control Technologies (MACT),” and lesser controls for non-major “area sources.” Since the Trump Administration took office, EPA has pursued several initiatives to make it easier for sources to reclassify from “major” to “area” in order to reduce their regulatory responsibilities. For example, in January 2018 EPA ended a decades-old policy declaring that every emission source that met major source criteria at the time a MACT became effective was “once in, always in” and could not requalify as a less-regulated area source by accepting legally binding controls that reduce its “potential to emit (PTE).” (I wrote about this change here).Read More
