The first path: internalize external costs by raising carbon prices. Carbon emission economic activities benefit individuals or enterprises, but the damage caused by climate change and air pollution is borne by the whole society. Therefore, through the increase of carbon price, the external cost of carbon emission is related to the private cost of the emitter. Under the constraint of carbon price, enterprises begin to take emission quota as one of the production factors, which helps to make hidden costs explicit and external costs internalized.

The second path: accelerate innovation and fundamentally change the mode of production. The so-called "carbon neutrality" is to reduce the carbon emission intensity of GDP, so we can achieve it by reducing the carbon emission intensity of unit energy consumption and reducing the energy consumption intensity of unit GDP. To achieve both, only through technological innovation.

The third path: improve the social governance system and encourage the whole people to reduce emissions. This path involves residents, enterprises and the government. For example, residents can put an end to waste through green catering, green home, garbage collection and supporting environmental protection, thus contributing to the realization of "carbon neutrality". Enterprises can reduce energy consumption, protect the environment, reduce emissions, recycle and enjoy economic and environmental, social and environmental development through product innovation. The government can introduce various policies, give appropriate subsidies and give active guidance, and each of us can participate in "carbon neutrality".
