Ecological environmental protection and economic development are not contradictory relations, but dialectical unity. Protecting the ecological environment means protecting the productive forces, and improving the ecological environment means developing the productive forces. Efforts to build a green, low-carbon circular economy system, accelerate the formation of an industrial structure with high scientific and technological content, low resource consumption, and less environmental pollution, and the process of greatly improving the degree of green economy will become a process of continuous enhancement of development potential and durability.

The port of Nanjing is a case in point. In the past few years, the Port of Nanjing has invested a lot of money in the construction of terminal oil and gas recovery equipment, oil and gas chemical terminal control platform, crude oil automatic process transformation and other projects. The investment in environmental protection not only improved the harsh environment of oil and gas in the past, but also led to the improvement of the performance of Nanjing Port for three consecutive years - environmental protection equipment recycled pollutants, greatly saving costs; Relying on the new equipment to carry out digital management, the loading and unloading efficiency and safety level of the port have been significantly improved. The relevant person in charge regrets that environmental protection and safety investment is not "wasting money" but "excellent value for money". This also tells us that development needs to be accounted for in a big, long-term, overall and comprehensive way. To achieve green transformation requires enormous efforts, but it can create new drivers and advantages for development.

To promote green protection, carbon reduction and emission reduction, policy guidance is indispensable. The Measures for the Administration of Voluntary Greenhouse Gas Emission Reduction Trading (Trial) were issued to regulate related transactions and activities; The Basic Rules of the Electricity Spot Market (Trial) was issued to streamline the mechanism for promoting the participation of new energy in the electricity market trading; "Green and low-carbon Advanced Technology Demonstration Project Implementation Plan" was released to help the development of green and low-carbon new industries and new forms of business... Since the beginning of this year, China has accelerated the construction of a policy mechanism conducive to green and low-carbon development, fiscal policy has been enriched, monetary tools have been continuously improved, price reform in the energy sector has deepened, and market transactions have become more active. We will continue to improve policies for green and low-carbon development, strengthen fiscal, tax and financial support, work together to reduce carbon, reduce pollution, expand green and grow, and accelerate the cultivation and expansion of green and low-carbon industries. We will continue to open up new racetracks, create new markets and create new economic growth points.

Promoting green and low-carbon economic and social development has both challenges and opportunities. Make great efforts, practice real efforts, unswervingly take the road of green development, take "green" as the bottom, and move toward "green", and play a good combination of policies such as rule of law, market, and science and technology, we will be able to better seize the opportunity, enhance the "gold content" of growth with the "green content" of development, and move steadily and far on the road of green, low-carbon and high-quality development.
