R-410A bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion, and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential (1700 times the effect of carbon dioxide), similar to that of R-22. Since R-410A allows for higher SEER ratings than an R-22 system, by reducing power consumption, the overall impact on global warming of R-410A systems will be substantially lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants.

Special Report on Global Warming of 1.5 °C developed, while new policies and research allows to improve efficiency in agriculture and industry. According to the report, with global warming of 1.5°C there would be increased risks to "health, livelihoods, food security, water supply, human security, and economic growth." Impact vectors include reduction in crop yields and nutritional quality. Livestock are also affected with rising temperatures through "changes in feed quality, spread of diseases, and water resource availability." "Risks from some vector-borne diseases, such as malaria and dengue fever, are projected to increase." "Limiting global warming to 1.5°C, compared with 2°C, could reduce the number of people both exposed
