The presence of microplastics—fragments of plastic smaller than 5 millimeters—is ever increasing across all types of environments, from cities to waterways. Moreover, microplastics do not biodegrade easily; the process can take hundreds of years. The ubiquity of durable microplastics in our environment, and the challenges we face in removing them due to their small size, has resulted in a significant amount of research intended to assess the ways by which microplastics can be eliminated.

A recent study in ACS Applied Materials & Interfaces is the …

Southern California is known for its beautiful beaches, perfect weather, and for being the smoggiest region in the nation. On May 7, 2021, the South Coast Air Quality Management District (SCAQMD) passed the Warehouse Indirect Source Rule (Warehouse Rule) in a 9-4 vote in an effort to combat Southern California’s smog problem. The Warehouse Rule is essentially a program that will focus on reducing the exposure of nitrogen oxide and diesel particulate matter in the air over the next three years. Specifically, the Warehouse Rule …

Microplastics, which are fragments of plastic smaller than 5 millimeters, have increasingly been released into the environment over the last several decades—primarily into bodies of water—whether during production, use, or degradation of plastic products. Microplastics have been found in over one hundred aquatic species, in sources of food such as crops, and within large plastic debris piles floating across the ocean. The prevalence of microplastics pollution across ecosystems, exacerbated by the fact that microplastics are not easy to biodegrade, has prompted proposals and passage of …

In a bid to curb the emission of greenhouse gasses and reduce American dependence on foreign oil sources, Congress passed the Energy Policy Act of 2005, which included the Renewable Fuel Standard (RFS). The RFS imposes Renewable Volume Obligations (RVO) on transportation fuel producers in the U.S., requiring them to include a threshold amount—increasing annually—of renewable fuels such as those derived from corn, grain, or sugarcane.

Though hailed by environmental groups as a step in the right direction, the RFS has promulgated the acceleration of …

The battle surrounding the regulation of automobile emissions standards lost some steam last week after a number of major automakers withdrew their support of the Safer Affordable Fuel-Efficient (SAFE) Vehicles rule enacted by the Trump administration.

Certain major car manufactures are looking to exit the federal litigation, in which automaker trade groups intervened on behalf of the federal government to support the SAFE rules that sought to strip states of the ability to set their own vehicle greenhouse gas emissions and fuel economy standards. These …
