Law Glossary
Trans fats are ingredients found in food, which can be artificial or naturally occurring. Meat and milk products may contain naturally occurring trans fats. Artificial trans fat is made by adding hydrogen to vegetable oil. The liquid then becomes a solid at room temperature. Research has shown that eating trans fats can be linked to cardiovascular disease. In 2015, the FDA determined that the primary source of artificial trans fats, partially hydrogenated oils (PHOs), are not generally regarded as safe (GRAS). PHOs are in many processed foods.

The International Convention for the Prevention of Pollution from Ships (MARPOL) is an international treaty established to protect the marine environment by reducing the amount of pollution from ships. It is divided into six annexes addressing different forms of pollution including oil pollution, noxious liquid substances, harmful substances in packaged form, sewage pollution, garbage pollution, and air pollution. The regulations apply to both commercial and leisure vessels and are enforced by countries that are parties to the convention.

Offshore wind or OSW is a term that refers to the generation of energy using wind turbines installed over bodies of water. Unlike onshore wind farms, offshore farms typically provide higher energy production because much larger turbines can be installed offshore than on land due to stronger and more consistent winds in marine environments. The energy created by offshore wind power is a renewable energy source and produces no greenhouse gas emissions, so it is considered an important component in the transition to net-zero emissions. Offshore wind projects are regulated at both the state and federal level including environmental regulations, safety standards, and permitting and licensing requirements. The Jones Act, which regulates maritime commerce in the United States, plays a critical role in how offshore wind projects are planned and constructed in U.S. waters.
