China has made its first ever commitment to cut its green house gas emissions ahead of next months climate change summit in Copenhagen.Beijing has pledged to chop its ‘Carbon Intensity’ by as much as 45 percent by 2020, based on 2005 levels. However, it said the figure would be measured on CO2 emitted for each unit of GDP. The announcement follows yesterday’s promise by the US to reduce its man made carbon emissions by about 17 percent by 2020, rising to 30 percent by 2025. But, critics claim the devil is in the detail. They say the US’ 17 percent 2020 cut will only result in a 3 percent drop below the UN’s 1990 benchmark. While, China’s commitment will lead to no real decrease because its economy is still growing fast. Environmentalists say the Amazon is one region already feeling the full effects of rising temperatures. They say immediate and real action is needed now. Andre Muggiati Coordinator of Greenpeace’s Amazon cattle ranching campaign said: ‘’“Rising global temperatures will have a significant impact on the Amazon rainforest’s structure, on its biodiversity. Some scientists estimate that large portions of the Amazon will no longer be a dense rainforest like they are now.” Eight Amazon countries are meeting today to try to draw up common goals ahead of the climate talks.. French President Nicolas Sarkozy is also at the summit in Manaus in Brazil on behalf of French Guiana, a country subject to large scale de-forestation. Sarkozy is expected to call for more ambitious reductions than the US and China are promising.
