How to reduce carbon dioxide emissions to achieve the purpose of improving the environment? In general, the measures to reduce energy consumption by industrial sector emissions, tend to affect economic growth, and the biological measures for carbon sequestration, carbon sequestration, not only will not affect economic growth, but also are of great benefit to improve the environment. Among them, forestry carbon sequestration refers to the use of forest carbon storage function, through afforestation, strengthen forest management, reduce deforestation, protection and restoration of forest vegetation and other activities, absorption and fixation of atmospheric carbon dioxide. Shrub, tree, vegetation and soil have carbon sink capacity as part of terrestrial ecosystem. Relevant data show that the tree grows 1 cubic meters of savings each year, can absorb 1.83 tons of carbon dioxide, release 1.62 tons of oxygen. Therefore, plants are natural "carbon absorbing and oxygen producing factories"".

With the development of world industrial economy and the rapid increase of population, carbon dioxide emissions are getting larger and larger. Carbon emissions are the general term for greenhouse gas emissions, and the most important gas in greenhouse gases is carbon dioxide. The increase in carbon dioxide emissions has not only had an unprecedented impact on the earth's ozone, but also had a serious impact on human health and the environment. Therefore, low carbon city has become a common pursuit around the world.

"12th Five-Year" period, Chengdu forestry carbon sequestration effect, the city's new forest area of about 300000 acres, the greening of the city increased, green coverage rate reached 39.85%, the ecological function enhancement of forest carbon sequestration, water conservation, soil and water conservation and ecological service function enhancement, the year effective protection forest 2 million 747 thousand mu, the area of soil and water loss in the city 45% effective governance. "13th Five-Year" period, through the green ecological protection, green ecological garden city construction, and promote the development of green industry four big green action, by 2020 the city's green industry demonstration base of more than 1 million acres, the forest coverage rate reached 40%, the formation of "integration of urban and rural green ecological network of urban green heart, the edge of the city green belt, suburban forest".
