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.

Global warming in Hawaii oil production per acre potentially far exceeding the levels found in vegetable oil crops. Cellana (previously called HR BioPetroleum) worked with Royal Dutch Shell on a pilot facility to grow algae on land leased from the Natural Energy Laboratory of Hawaii Authority, which is located on the west shore of the island of Hawaii. Global warming in Hawaii Hawaii Governor Linda Lingle has approved a number of energy-related bills to address climate change and promote local renewable energy production. The governor's energy bill-signing streak started in late April 2008 with the approval of House Bill 2502, which allows solar energy
