On March 24, in Kelsey Cascadia Rose Juliana et al. v. United States of America et al., the U.S. Supreme Court rejected a petition to hear an appeal from Our Children’s Trust from the Ninth Circuit Court of Appeals decision concluding that a lawsuit from youths alleging that current federal energy policies harm their future by exacerbating climate change.

In an order with no explanation, the Supreme Court Justices denied the petition for a writ of certiorari, which means the Ninth Circuit Court of …

We have relied upon lithium-ion batteries to power electric vehicles and mobile phones, among other things, almost since the inception of their respective industries. But the mining and processing necessary to manufacture these batteries provides one of their major drawbacks—not only does their production pose environmental and human costs, but their improper disposal can inject toxins into the environment.

Sodium, which is both cheaper and more environmentally friendly than lithium, recently emerged as a promising alternative. Sodium-ion batteries also last much longer than their lithium-based …

A couple of months ago, our blog published an article on the exploding ubiquity of Trifluoroacetic acid (TFA) in the environment.

TFA is a breakdown product of several hydrochlorofluorocarbons (HCFC). It is regulated under the Montreal Protocol (MP), and hydrofluorocarbons (HFC) used mainly as refrigerants.

Trifluoroacetic acid is (1) produced naturally and synthetically, (2) used in the chemical industry, and (3) a potential environmental breakdown product of a large number (>1 million) chemicals, including pharmaceuticals, pesticides, and polymers.

In 2016, EPA stated that the “formation …

Through the modern industrial age, there’s always been a push-and-pull between the utility of our innovations and the risks they often inadvertently create. In the 70’s, we discovered the synthetic pesticide that was so effectively combating typhus and malaria, DDT, was causing breast cancer and impairing neurological development in babies. In the 80’s and 90’s, the CFCs that we used as aerosol propellants and refrigerant turned out to be damaging to the ozone layer.

Recently, it’s gotten more complicated: We still enjoy the increased power …

As coastal erosion continues to shrink beaches, the sand that remains has become ever more valuable; and in Maine, a battle over the beach has reached the state’s highest court.

In most coastal states, the intertidal land — (the land subject to the ebb and flow of the tides) — is owned by the state in trust for the public under the public trust doctrine. Thus, the public is generally entitled to use the intertidal zone for recreational purposes. Maine is one of only a few …

The Federal Aviation Administration (FAA) is responsible for licensing the companies that charter private space transportation. To issue a license for commercial space travel, the FAA is required under the National Environmental Policy Act to assess how their licensees’ activities may impact the environment.

FAA policy requires before issuing a license for space travel that the agency assess 14 separate categories, including noise, coastal resources, and land use, for potential environmental impact. In addition to this environmental review, the FAA also assesses how commercial space …

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 …
