Whakakī i te rerenga e whai ake nei: I ngā Huihuinga o Gleneagles (2005) me St. Petersburg (2006), i kī te Rōpū o ngā Whenua Tauhokohoko (G8) i te hiahia mō te mahi tahi o te ao i te mara o te
33rd G8 summit at Heiligendamm in June 2007, the G8 approved an EU proposal for an international initiative on energy efficiency and decided to explore the most efficient way to promote energy efficiency worldwide, jointly with the International Energy Agency (IEA). I whakaaetia e te G8 tētahi tono a te EU mō tētahi kaupapa ā-ao mō te tōtika o te pūngao, ā, i whakatauhia kia tirotirohia te huarahi tino whai hua ki te whakatairanga i te tōtika o te pūngao i te ao, i te taha o te International Energy Agency (IEA).
