What is a carbon sink forest?

Recently, low-carbon economy is very popular. The Copenhagen International Climate Conference is about carbon emissions. Wenzhou people who dare to be the first will not fall behind. Wenzhou newspapers have reported many times that citizens actively buy carbon sinks and build carbon sinks to achieve zero carbon emissions. The new nouns are also very interesting. So what is a carbon sink? In layman's terms, carbon sequestration is afforestation. Because the photosynthesis of plants absorbs carbon dioxide, the forest built with this name is a carbon sink forest. The newspaper also reported that the market has achieved zero carbon emissions, that is, the carbon dioxide released from the market every year is equal to the carbon dioxide absorbed through afforestation, which offsets each other. This is the so-called zero carbon emissions. (Is it that simple? So what is a low-carbon economy? In other words, the economic model based on low energy consumption, low pollution and low emission is another major progress of human society after agriculture and industrial civilization. The essence of low-carbon economy is to use energy efficiently, develop clean energy and pursue green GDP. The core is the innovation of energy technology and emission reduction technology, the innovation of industrial structure and system, and the fundamental change of human survival and development concept. In fact, low-carbon economy is a political game in the final analysis (there is disagreement with the conclusion that global warming is all caused by carbon dioxide), which is related to a country's future development. The reason why developed countries put forward the concept of low carbon is mainly based on the following considerations: 1. Because developing countries have a large population, if they all develop themselves according to the standards of developed countries, the earth environment will be unbearable and will inevitably endanger their own living environment; 2. Through the concept of low carbon, we can strategically curb the sustainable development of developing countries and control the continuous deterioration of the environment; 3. By controlling carbon emissions, developed countries can buy carbon emissions from developing countries to maintain their own operation, and the control of carbon emissions can be completely realized through the capital market, just like sitting on a stock. From this theoretical perspective, which currency carbon trading is tied to, which market plays a greater role in carbon trading, and who makes rules determines who sits on the farm. So this is a game between countries and a question of national strategy. China had to deal with it, and there was no way out. Before Copenhagen, China promised to reduce carbon emissions by 40-45% in 2020 compared with 2005, which is an example. To put it simply, the low-carbon economy has the following aspects: First, energy saving, energy saving by improving efficiency, how to improve efficiency? Through new technologies and new products, while eliminating backward technologies. Then, for example, energy-saving household appliances (including lighting), small-displacement cars, smart grids and so on. This year, small-displacement cars have obtained preferential policies of national purchase tax reduction and exemption. Smart grid can greatly improve transmission efficiency and reduce transmission loss. In addition, if new materials are used, the energy-saving effect can also be achieved. Such as the use of new building materials and new conductive materials. The second is emission reduction. There are two main ways to reduce emissions: 1, using new technologies to reduce emissions itself; New technologies such as clean coal technology can greatly reduce emissions. 2. Achieve the effect of emission reduction through governance. Third, new energy, the energy used by mankind in modern times is mainly oil, coal and natural gas, which has also been exhausted (in fact, there is no low emission, but it is actually a conspiracy of developed countries to contain developing countries). Due to more and more industrialized countries, the environmental pollution caused by these traditional energy sources has actually become more and more serious. Now the energy bottleneck is actually a big problem for all mankind, and there is no way out. At present, the development of new energy mainly includes the following categories: wind power, nuclear power, hydropower, photovoltaic power generation, biomass power generation, geothermal energy, hydrogen energy and so on. Fourth, carbon sink: that is, increasing the absorption capacity of carbon dioxide through afforestation.
