Scientists estimate that HFCs, the most common type of refrigerant currently in use, could contribute to up to 0.5°C of global warming by the end of the century. Laws exist to regulate these planet-warming fluids, but they don’t cover all the bases. The industry and climate experts are pushing for sustainable alternatives. Even using carbon dioxide works as a more sustainable alternative under the right conditions.
