An analysis of reduction opportunities for consumption of hydrofluorocarbons and comparisons to US climate policy proposals

Many of the most cost-effective options for reducing emissions of hydrofluorocarbons (HFCs) involve: reducing leaks; responsible handling practices; replacement with a substance with little or no global warming potential; or reducing the amount of the greenhouse gas (GHG) needed. Some of these options can be implemented immediately for quick emission reductions. However, because many of the types of equipment that rely on these gases have lifetimes ranging from 10 to 30 years, fully implementing these emission reductions can take decades. Reductions in HFC consumption, however, can generally be seen more immediately. Recent US proposals for climate legislation have considered limits on HFC consumption under a cap separate from other [...]
