A new carbon emission reduction mechanism: Carbon Generalized System of Preferences (CGSP).

Countries throughout the whole world, including China, are working together to curb the greenhouse effect, but the effects seem very limited in spite of the fact that various low-carbon development strategies have been adopted, particularly in industrial enterprises. Therefore, carbon emissions caused by the public should be taken seriously, and the public should be encouraged to engage in behavior that limits carbon emissions. Therefore, this article introduces a new incentive mechanism called the Carbon Generalized System of Preferences (CGSP), which was first introduced in Guangdong Province, China. It is believed that this new mechanism matches the role of leadership in Guangdong in the urbanization and economic development of China by addressing the small sources of greenhouse gases (GHGs) and by issuing carbon coins. Compared with Chinese Certified Emission Reduction (CCER), the development scope, management level, and novel criteria of CGSP are very different but relatively easy for the public to accept. The CGSP shows that the network platform, reduced carbon emissions, and urban pilots are all compatible with the goals of the nation and city, and they promote the CGSP in different ways. Because of its consistency with ecological civilization in China, the prospect of the CGSP is bright; however, there are some challenges, such as policy and economic factors, combined with pollution control.

[Activation tagging and the application in plant genetic engineering].

Activation tagging is a new method for isolation and functional identification. It can generate dominant gain-of-function mutants by overexpression of a particular endogenous gene. Due to this special characteristics of activation tagging,this method has been a powerful tool for new gene discovery and gene functional analysis. This paper reviewed the principle and study conditions of activation tagging,as well as its use in plant genetic engineering.
