EPA Seeks Public Comment on Heavy-Duty Truck Emissions Proposals
In the second step taken under the Cleaner Trucks Initiative (CTI) it announced in November 2018, the EPA has released an advance notice of proposed rulemaking (ANPR) to solicit public comment on the outlines of proposed emissions standards for highway heavy-duty engines, which the Agency says it plans to issue in early 2020.
Many Processes—But Few Solutions—for Industrial GHG Emissions
In 2017, industrial activity accounted for 22% of U.S. greenhouse gas (GHG) emissions, third behind transportation (29%) and electricity (28%). When adding indirect emissions from the off-site generation of electricity needed to power industrial facilities, the share increases to 29.7%.
EPA’s Repeal of California Waiver Sets Up Legal Contest
With the exception of a waiver denial in 2007—which was later reversed—the EPA has granted every request California has made since the first request was granted in 1968 to allow the state to set its own vehicle emissions standards. That record is now ended with the EPA’s final rule that withdraws its January 2013 waiver […]

With several minor exceptions, the EPA is proposing to grant each of the requests four small-volume manufacturers (SVM) made for alternative greenhouse gas (GHG) emissions standards for their light-duty vehicles.
NEPA Draft Guidance: Comment Period Extended, Climate Considerations Mostly Absent
In response to public requests, the White House Council on Environmental Quality (CEQ) is extending the comment period on its draft National Environmental Policy Act Guidance on Consideration of Greenhouse Gas Emissions. Comments on the draft will now be accepted by the CEQ until August 26, 2019.
RFS Has Only a Small Impact on GHG Emissions

Cities Take Action on Renewable Energy, Reduction of GHG Emissions
Hundreds of U.S. cities of all sizes are not waiting for the federal government to recommit to reducing greenhouse gas (GHG) emissions and regain its position as the world leader in stemming climate change. At an April 2, 2019, House hearing, the mayors of three of those cities told their stories of commitment to a […]
Senators Look for Answers on Methane Proposal from EPA
Several federal lawmakers continue to press the EPA for information about the impact of its proposal (October 15, 2018, Federal Register (FR)) to weaken the Obama administration’s New Source Performance Standards (NSPS) governing air emissions from the oil and natural gas (O&G) sector (June 3, 2016, FR).
GHG Program in Oregon Found (Appropriately) Discriminatory
In a majority opinion, a panel of the U.S. Court of Appeals for the 9th Circuit found that Oregon state violated neither the dormant Interstate Commerce Clause nor a provision of the federal Clean Air Act (CAA) when it assigned a carbon intensity value to transportation fuels produced out of state and imported into Oregon, […]
