If Kavanaugh were confirmed as a Supreme Court justice and the hydrofluorocarbon case came to the court, he would be recused.
The report broadly segments the market for foam blowing agents based on product type as: Hydrocarbons (HC), Hydrochlorofluorocarbons (HCFC), Hydrofluorocarbons (HFC), and others (hydrazine, azodicarbonamide, CO2, and water).
The new regulation, adopted with 46 votes in favour, one against and three abstentions, provides for a progressive reduction of the marketing of hydrofluorocarbons (HFCs) by 79%, so that the volume of products placed on the market in 2030 will not be more than 21% compared with current levels.
This decision to systematically introduce these commercial horizontal ice cream chest freezers across Europe, is a part of Nestle's commitment to progressively phase out the use of high global warming potential refrigerants, such as hydrofluorocarbons (HFC).
A faster way may be to limit methane, ozone, hydrofluorocarbons and soot, also known as black carbon.
Under the Protocol, 37 countries ("Annex I countries") commit themselves to a reduction of four greenhouse gases (GHG) (carbon dioxide, methane, nitrous oxide, sulphur hexafluoride) and two groups of gases (hydrofluorocarbons and perfluorocarbons) produced by them, and all member countries give general commitments.
Looking first at agents then at systems, contributors mostly from chemical and ultrasound companies explore such topics as hydrofluorocarbons, vapor degreasing with traditional chlorinated solvents, ultrasonic cleaning with two frequencies, from laboratory cleaning to production cleaning, cleaning with micro sandblasters, gas plasma as a dry process for cleaning and surface treatment, and liquid displacement drying techniques.
EPA's final determination will subject emissions of carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), and sulfur hexafluoride (SF6) to the regulatory and permit requirements of the Clean Air Act (CAA).
Greenhouse gases from hydrofluorocarbons are partly blamed for global climate change and are expected to make up 28 to 45 percent of carbon emissions by 2050.
Scientists are now discovering that CFCs' replacement chemicals, hydrofluorocarbons (HFCs), are an extremely powerful greenhouse gas.
WASHINGTON, Sept 16, 2009 (TAP) - The United States, Canada and Mexico have proposed using an existing international protocol to reduce emissions of potent greenhouse gases called hydrofluorocarbons (HFCs) used in refrigerators and air conditioners, the State Department said on Tuesday.<p>The State Department said the three countries believed the Montreal Protocol, which regulates hydrochlorofluorocarbons (HCFCs) blamed for depleting the ozone layer, could also help phase down hydrofluorocarbons (HFCs) used in cooling equipment, which are expected to increase sharply in coming years.
