Preliminary analysis indicates that approximately 450 TWh of final energy and 210 million metric tons of CO2 emissions can be saved in 2030 by adopting the world’s best lighting efficiency standards in participating Clean Energy Ministerial (CEM) economies. Energy consumed by lighting accounts for approximately 1900 MT of CO2 emissions each year, which is equivalent to 70 percent of the total emissions produced by vehicles annually. Conservative estimates predict that energy demands for lighting will increase by 80 percent by 2030.
The efficiency improvement potential offered by solid state lighting products has the potential to significantly reduce the global share of energy consumption attributed to lighting. To date, only four global economies have developed minimum efficiency standards or labeling programs for LED lighting and lamps, though many countries have quality and safety standards in place.
