Living in a De Novo World – Life after Chevron

On June 28, in a 6-3 decision, the Supreme Court in Loper Bright Enterprises, et al. v. Raimondo Secretary of Commerce, et al., held that federal courts must exercise independent judgment in deciding whether a federal agency has acted within its statutory authority. This decision upends 40 years of precedent set forth by the court’s prior finding in Chevron v. Natural Resources Defense Council (“Chevron”). 

Until now, it was well known that Chevron was the legal standard in administrative law for determining …

AI – Environmental Friend or Foe?

Recently, there’s been much discussion about the potential benefits that artificial intelligence can bring to climate change regulation. 

For example, advanced technology, such as satellite data, is being used to identify large emission events — (see ELM’s recent methane rule finalization coverage here and ELM’s previous AI coverage here). AI also is being used to monitor rising sea levels along the United States’ coastlines — (see ELM’s previous sea level coverage here). 

Less consideration, however, has been given to the potential adverse impacts …

Greenhouse Gas Regulation Heats Up as EPA Finalizes Rule for Reducing & Reporting Methane Emissions

After much anticipation, the Environmental Protection Agency issued its final rule this week aimed at cutting methane emissions as well as strengthening and updating greenhouse gas emissions (GHG) reporting for the oil and gas industries.

Methane is a “super pollutant” that is many times more potent than carbon dioxide. Methane also contributes to approximately one third of the global warming from GHGs today, and the oil and natural gas sector is the largest industrial source of methane emissions in the United States.  Toward that end, …

EPA Finalizes New Rule Requiring More Than 200 Chemical Plants to Reduce Toxic Emissions

The U.S. Environmental Protection Agency announced April 9 a set of final rules under sections 111 and 112 of the Clean Air Act (CAA) to significantly reduce toxic air pollution from more than 200 chemical plants in the United States.

The plants affected make products such as synthetic organic chemicals, plastics, paints, synthetic fabrics, pesticides, petrochemical products, and various polymers and resins, including neoprene. The new rules strengthen protections for communities living near these industrial facilities, especially along the Gulf Coast, and it is anticipated …

Minimizing Methane: New Studies Find Methane Emissions Significantly Higher than Previously Thought

A new report by the International Energy Agency, released on March 13, found that for the third year in a row, methane released by the fossil fuel industry rose to an almost record high in 2023. 

Methane emissions are a significant contributor to global warming, second only to carbon dioxide. Although methane is better at trapping heat into the atmosphere, trapping almost 80 times more heat than carbon dioxide over a two-decade period, it is relatively short-lived, making it an attractive way to more efficiently …

Green Amendments and the Rise of Environmental Constitutional Rights

There has been a recent push across the country placing “green amendments” at the forefront of the fight to combat climate change and promote environmental justice. Analogous to the rights enumerated in the Bill of Rights, such as freedom of speech or freedom of religion, a green amendment is an amendment to a state Constitution’s Bill of Rights that guarantees its citizens the inalienable right to clean air, clean water, and a healthy environment. These amendments serve to create a constitutional mandate that every citizen has a …

Leading with Lead: EPA to Implement Strategy for Lead in 2024

The U.S. Environmental Protection Agency kicked off the New Year by strengthening its guidance for investigating and cleaning up lead-contaminated soil at residential properties, especially in areas where children live and play. Toward this end, the EPA lowered the recommended screening levels for lead in residential soil, from 400 parts per million to 200 ppm, for the first time in 30 years. 

While screening levels are not cleanup standard, this change is expected to assist the EPA in making site-specific cleanup decisions, which may include …

EPA Announces Final Rule to Reduce Methane and Combat Climate Change

In recent years, the global concentration of methane present in the atmosphere has increased dramatically. In fact, in 2021, methane increased by almost 18 parts per billion in the atmosphere, the largest single year increase since the National Oceanic and Atmospheric Administration’s records began in 1984. Last year was no exception, as atmospheric methane increased by 14 parts per billion, the fourth largest recorded increase.

These numbers are significant because methane is known as a “super pollutant” that is many times more potent than carbon …

Green Technologies and their Impact on Groundwater: How Green is Green?

As the Biden Administration pushes to transition the country away from fossil fuels to green energy sources, we have been faced with the reality that demand for these necessary minerals could soon outpace supply. For example, electric vehicle manufactures have been searching for additional sources of lithium to meet the Administration’s call for electric vehicles to make up approximately 50 percent of all cars by 2030. Similarly, it is estimated that the world will need almost 50 percent more than its current supply of copper …

EPA Announces Latest Actions to Address Hydrofluorocarbons

Nearly one year after ratifying the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer, the Environmental Protection Agency announced two additional actions to further this initiative under the American Innovation and Manufacturing Act (AIM).  The Kigali Amendment is an international agreement aimed at phasing down the production and consumption of hydrofluorocarbons (“HFCs”) by 80-85 percent by 2047. It also seeks to avoid up to .5 °C of global warming by 2100.

By way of background, HFCs are used in applications …
