Bosch Rexroth (China) Ltd. invested million in October 2006 in plant expansions in Beijing and Changzhou, Jiangsu Province. Earlier in 2006 Bosch Rexroth started up its Shanghai Jinqiao (Golden Bridge) factory, which is involved in the manufacture, installation, distribution and service of transmission and control parts and systems; the Shanghai facility will also serve as Bosch's principal center for technology, personnel and distribution in China. Environmental protection and energy conservation According to China's "Energy Blue Paper" recently written by the Chinese Academy of Social Sciences, the average rate of recovery of coal from mining in China is only 30%, less than one-half the rate of recovery throughout the world; the rate of recovery of coal resources in the US, Australia, Germany and Canada is ~80%. The rate of recovery of coal from mining in Shanxi, China's largest source of coal is approximately 40%, though the rate of recovery of village and township coal mines in Shanxi Province is only 10%–20%. Cumulatively over the course of the past 20 years (1980–2000) China has wasted upwards of 28 gigatons of coal. The same causes for a low rate of recovery in coal mining – that extraction methods are backward – lead to safety problems in China's coal mining sector. Another reason for the low rate of recovery is that the majority of extraction comes from small-scale mining; of the 346.9 gigatons of coal extracted by China, only 98 gigatons has come from large or mid-sized mines while 250 gigatons are extracted from small mines. Based on coal production in 2005 of 2.19 gigatons and a current rate of recovery of 30%, if China were able to double its rate of recovery it would save approximately 3.5 gigatons of coal. On 13 April 2007, the Department of Science, Technology and Education of the Chinese Ministry of Agriculture hosted the Asian regional workshop on adaptation to climate change organised by the United Nations Framework Convention on Climate Change (UNFCCC). Climate change will affect Asian countries in different but consistently negative ways. Temperate regions will experience changes in boreal forest cover, while vanishing mountain glaciers will cause problems such as water shortages and increased risks of glacial lake flooding. Coastal zones are under increasing risk from sea level rises as well as pollution and overexploitation of natural resources. In 2006 in China storms, floods, heat and drought killed more than 2,700 people; effects ranged from
