What is the GWP range for halocarbons?

Halocarbons, which include substances like chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs), have a Global Warming Potential (GWP) that typically falls within the range of hundreds to thousands. GWP is a measure used to compare the impact of different greenhouse gases on global warming relative to carbon dioxide over a specific time frame, usually 100 years.

Halocarbons are known for their potent heat-trapping abilities, which can be significantly higher than those of carbon dioxide. For example, certain HFCs can have a GWP that exceeds 1,000 times that of CO2. This high GWP reflects their effectiveness in contributing to climate change, making their regulation and reduction a crucial part of global climate policy efforts.

The other ranges provided do not adequately reflect the potent impact these substances have on global warming, as they do not include the higher GWP values characteristic of halocarbons. Thus, the response identifying a range from 100s to 1000s is accurate and underscores the significant environmental concerns surrounding halocarbon use and emissions.
