Climate change in Japan and Toyota hybrid electric vehicles were named to have the highest fuel efficiency and lowest emissions. The fuel economy and emissions decrease is due to the advanced technology in hybrid systems, biofuels, use of lighter weight material and better engineering. As a signatory of the Kyoto Protocol, and host of the 1997 conference which created it, Japan is under treaty obligations to reduce its carbon dioxide emissions and to take other steps related to curbing climate change. The Cool Biz campaign introduced under former Prime Minister Junichiro Koizumi was targeted at reducing energy use through the reduction of air conditioning
Climate change in Argentina in much of central–western Argentina and Patagonia, precipitation is predicted to decrease. Because Argentina is potentially vulnerable to climate change, such projected changes based on the models could enhance current or create new problems associated with climate change on Argentina. Agriculture will be affected by climate change. The decrease in precipitation that has been observed in the Andes will be predicted to continue to decrease, affecting hydroelectric energy even more. Glaciers are predicted to continue to recede and melt or in some areas, disappear. It is predicted that the Cuyo region could face a potential water crisis due to an
