have taken effect on 1 January 2020. California, Colorado, Nevada, Washington, and Vermont had already adopted their own energy standards. The ruling in the manufacturer's favor would have allowed some types of incandescent bulbs to remain in service despite state regulations. A judge ruled that the state efficiency standards were proper under the congressional exemption previously granted. Oceania Australia In February 2007, Australia enacted a law that, in effect, by legislating efficiency standards, disallow most sales of incandescent light bulbs by 2010. The Australian Federal Government announced minimum energy performance standards (MEPS) for lighting products. The new minimum standard efficiency level is 15 lumens per watt (lm/W). From November 2008, no non-compliant lighting (including some incandescent globes) were imported into Australia, and from November 2009, the retail sale of non-compliant lighting was banned. It was proposed that all regular light bulbs and some other kinds of light bulbs sold from October 2009 would have to meet the new minimum energy performance standards. Incandescent light bulbs that meet the new standards, for example high-efficiency halogen bulbs, would continue to be available. It is estimated that greenhouse gas emissions will be cut by 800,000 tonnes (Australia's current emission total is 564.7 million tonnes), a saving of approximately 0.14%. There were some initiatives to encourage people to switch to compact fluorescent lamps ahead of the phase out. Australia will ban halogen light bulbs from September 2020. New Zealand In February 2007, then Climate Change Minister David Parker, Labour party, announced a similar proposal to the one in Australia, except that importation for personal use would have been allowed. However, this proposal was scrapped in December 2008, after a change of government, and incandescent bulbs continue to be available . South America Argentina In Argentina, selling and importing incandescent light bulbs has been forbidden since 31 December 2010. Bolivia Bolivia is reported to have banned incandescent light bulbs on 1 January 2014. Brazil As specified in Interministerial Ordinance 1,007 of 31 December 2010, incandescent light bulbs must perform according to certain levels of luminous efficacy to be produced, imported and sold in Brazil. Non-conforming light bulbs are being gradually phased out. Since July 2013, bulbs ranging from 61 to 100 Watts which do not perform accordingly can no longer be produced or imported, but they could be sold until mid-2014. Since the end of June 2016, incandescent bulbs have been completely prohibited in Brazil.
