China minimizes greenhouse gas emissions

Ice melting, sea level rise, frequency of strong storms and tornadoes along with floods and droughts increase, causing serious damage to people. These are the consequences of the greenhouse effect that warms the Earth's atmosphere, which is caused by the emissions produced by human activity, mainly six gases: carbon dioxide (CO2), methane (CH ₄ ), nitrous oxide (N ₂ O), carbon hydrofluoro (HFC), polyfluoro carbon (PFC) and hexafluorur sulfur (SF6). CO ₂ accumulates in the atmosphere due to burning fossil fuels such as petroleum and coal; CH ₄ is a major component of natural gas in oil fields, or produced from lagoon ponds, waste, and organic fertilizers. N ₂ O mainly comes from animal feces and urine. The remaining gas arises in chemical production.

Kyoto Protocol is an international treaty, which was established in 1997 in Kyoto (Japan), stipulating the level of major greenhouse gas emission reductions in 2008-2012 is about 5% compared to the level of in 1990, which 35 industrialized nations had to implement, of which the European Union fell 8%, Japan fell 6%. The Protocol came into effect on February 16, 2005, when ratified by 141 countries, these countries ' contributed ' 55% of global greenhouse gas emissions. However, enforcement faces many obstacles because the United States, which has the most emissions in the world, does not approve, and some other developing countries have many emissions such as China (China) and India. Brazil was not required to implement this protocol until 2012.

Although China (China) has not been bound to cut emissions, but before the storms and floods are worsening and the temperature is warm, China encourages the implementation of emission reduction projects. . Since 2002, China has ratified the Kyoto Protocol, developing clean energy. As of early 2007, China has approved about 300 projects on clean energy development, involving many industries such as electricity, coal, chemicals . For example, wind power projects with a capacity of 100 MW. In the Northern Inner Mongolia Autonomous Region, after completion, each year, about 250 thousand tons of CO2 can be reduced.

Some coal mines in An Huy and Central provinces are building a project to recover and utilize methane gas. After inauguration, this project can reduce nearly 300 thousand tons of CO2 annually. The HFC gases are greenhouse gases thousands of times higher than CO2. Currently, Zhejiang Province is building a HFC resolution project by burning at a high temperature to turn HFC into hydrogen fluoride (HF) and hydrochloric acid (HCl), thus lowering the house-effect emissions. glasses.

Earlier this year, China cooperated with the UN Development Program, built technical service centers on clean energy development mechanisms in 12 provinces and autonomous regions, to provide technology support for gas mitigation. waste. According to China's 11th five-year development plan, by 2010, the energy consumption per unit of Gross Domestic Product (GDP) will decrease by 20% compared to the end of 2005. Meanwhile, the proportion Renewable energy in the energy structure will increase by 10%.
