Environment Ministers Meet to Accelerate Transition to a Low Carbon Society - More than doubling annual improvements in energy efficiency could play a key role in averting catastrophic climate change, a report to environment ministers says. The Intergovernmental Panel on Climate Change (IPCC), 2,000 plus scientists established by UNEP and the World Meteorological Organisation to advise governments, estimates that to avoid dangerous climate change emissions need to be stabilized at between 535 to 590 ppm in 2050. An increase in investments in low carbon and renewable energies is also underway which, if accelerated and fostered widely could also assist in meeting global climate change targets alongside helping to achieve the Millennium Development Goals. Currently close to 60 countries have targets for renewables including 13 developing countries while around 80 have market mechanisms in place-feed-in tariffs and renewable portfolio standards- to encourage renewable energy development. The new report, drafted to assist the ministerial discussions, notes that more than 2.
