Evolutionary game-based optimization of green certificate-carbon emission right-electricity joint market for thermal-wind-photovoltaic power system

With the increasing proportion of renewable energy in the power market,the demands on government financial subsidies are gradually increasing.Thus,a joint green certificate-carbon emission right-electricity multi-market trading process is proposed to study the market-based strategy for renewable energy.Considering the commodity characteristics of green certificates and carbon emission rights,the dynamic cost models of green certificates and carbon rights are constructed based on the Rubinstein game and ladder pricing models.Furthermore,considering the irrational bidding behavior of energy suppliers in the actual electricity market,an evolutionary game based multi-market bidding optimization model is presented.Subsequently,it is solved using a composite differential evolutionary algorithm.Finally,the case study results reveal that the proposed model can increase profits and the consumption rate of renewable energy and reduce carbon emission.

A study of legal attributes of carbon emission rights in carbon trading

Clean Development Mechanism (CDM) has given birth to an international carbon trading market prosperity, which provides developing countries with valuable opportunity to address climate change issues right along with economic development and environmental improvement to achieve sustainable development. However, most studies of CDM focus on economics, and few on its legal problems. CDM involves too many aspects. And the clear legal attribute of trading object is the basis of progress of the transaction and also the start point of legal protection. Therefore, this paper in accordance with the inherent principle of property rights economics, and environmental economics in CDM, only discusses CDM carbon emission right legal interpretation and its attribution. The paper recommends that in order to ensure and promote the carbon emission right trading, carbon emission right should be attributed into the system of real rights to be regulated by Real Right Law. In this way, carbon emission right can gain exclusive power of possession and use, which can achieve a clear right def inition of environmental goods in line with Coase's theory to protect Chinese prof it in carbon trading market and promote the development of the carbon trading market further.

Prospects for the transformation and development of carbon storage in abandoned mines of coal enterprises from the perspective ofcarbon neutrality

Under the carbon neutrality goal,coal enterprises must seek breakthroughs from abandoned mines,develop new resources in the new era,turn problems into countermeasures,and participate in the carbon emissions market,for contributing to the accomplishment of the national strategic goal of carbon neutrality.To this end,we investigated the relevant national policies and regulations to clarify the boundaries disclosed by the carbon information of enterprises,understood the development direction of carbon storage in abandoned mines,and clarified the transformation and development of carbon storage in aban-doned mines.We made a few suggestions:(1)China should learn from its past experience and other countries to develop the energy industry with Chinese characteristics and reform the economic system.(2)Coal enterprises must actively respond to the national carbon information disclosure policy,clarify their own responsibilities and carbon emission boundaries.(3)It is necessary to proactively obtain advanced knowledge and plan carbon storage pathways for abandoned mines.(4)Devel-opment problems of coal enterprises should be deduced using cases.The'dual carbon'goals should be achieved steadily step-by-step.(5)Three measures,i.e.improving the existing resource structure,coordinating the information of abandoned mines,and promoting the cultivation of scientific and technological talents.

Research on Carbon Reduction Strategy of China’s Industrial Chain with the Goal of Carbon Emission Peak and Carbon Neutrality

In order to achieve the development goals of emission peak in 2030 and carbon neutrality in 2060,carbon reduction measures should be implemented in the whole industrial chain.Based on the existing research,the basic logic of carbon reduction in the industrial chain is analyzed,and then the specific strategies for carbon reduction in the industrial chain are proposed,including:reducing the use of fossil energy and vigorously developing the new energy industry;reducing carbon through energy conservation,industrial upgrading,development of circular economy,and application of carbon capture technology;reducing carbon through low-carbon transformation of logistics industry,innovation of trading methods,and promotion of low-carbon green consumption.The external guarantee system for carbon reduction includes the introduction of relevant policies,laws and regulations,and the use of carbon emission trading mechanism.
