SLCP stands for "Short-lived climate pollutants". These are substances that remain in the earth's atmosphere for a relatively short period of time and contribute to climate change. Some common SLCPs include methane, black carbon, and hydrofluorocarbons. There are several synonyms for SLCP, and these include "short-lived greenhouse gases", "fast-action climate pollutants", and "near-term climate forcers". These terms are used interchangeably, depending on the context in which they are being used. Reducing SLCP emissions is a critical aspect of mitigating climate change, as these pollutants have a shorter lifespan than other greenhouse gases and their reduction can lead to immediate environmental benefits.
