Hydrofluorocarbons, Climate, and Health HFCs were introduced as ozone-friendly substitutes for chlorofluorocarbons, but they, too, are greenhouse gases. The use of HFCs in insulation, refrigeration...

HFCs are synthetic chemicals used mainly in fridges and air conditioning, but also in fire extinguishers and as solvents. HFCs, like aviation and shipping , were omitted from the Paris Agreement, despite being a potent greenhouse gas.

Hydrofluorocarbons (HFCs) are a group of synthetic gases primarily used for cooling and refrigeration. Many HFCs are very powerful, short-lived climate pollutants with an average atmospheric lifetime of 15 years.

Learn what high-fructose corn syrup is, how it differs from sugar, and what health effects it may have. Find out how to cut down on this liquid sweetener in your diet and what foods contain it.

High-fructose corn syrup (HFCS) is a sugar-based sweetener derived from corn. It has a slightly higher fructose content than regular sugar, but the difference is not significant for health effects. Learn more about the production, types, and health implications of HFCS.

High fructose corn syrup (HFCS) is a sweetener made from corn starch that can cause tooth decay, obesity, and metabolic syndrome. Learn about the sources, effects, and alternatives of HFCS, and how to check the labels of foods that contain it.

1. Introduction. High-fructose corn syrup (HFCS) is derived from cornstarch via two steps: 1) enzymatic hydrolysis of starch to glucose followed by isomerization of glucose into fructose and 2) fractionation process ( Souzanchi et al., 2019 ). The HFCS is richer in fructose than pure glucose in corn syrup (100% glucose).

Hydrofluorocarbons ( HFCs) are man-made organic compounds that contain fluorine and hydrogen atoms, and are the most common type of organofluorine compounds. Most are gases at room temperature and pressure. They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC ...

Learn about the AIM Act, which authorizes EPA to reduce HFCs, a potent greenhouse gas, by phasing them down, reclaiming them, and transitioning to next-generation technologies. Find information on allowances, data, rulemakings, and public meetings related to HFCs.

The U.S. is already taking steps to eliminate HFCs. Reducing HFCs is one area of climate policy where environmentalists, manufacturers and politicians tend to agree.
