The first is political factors. The carbon trading market originated from international political agreements with legal effect such as Kyoto Protocol. Similar to other energy sources such as oil and natural gas, the price of carbon dioxide is deeply influenced by political factors. After the Kyoto Protocol expires, market participants should always pay attention to NAPs, connection mechanism and international agreements. These emission reduction plans and quotas largely determine the space of the carbon trading market. According to experts on easy carbon, if a country's emission reduction plan is too loose, resulting in the scarcity of corporate carbon emissions, it will not be able to form an effective market. The second factor is supply and demand. Like any other product, the analysis of carbon price needs to consider the relationship between supply and demand in its market. The supply of carbon products is mainly nap of various countries, and all quotas that can be traded in the market are decided by governments of various countries. The demand for carbon products comes from planned enterprises and institutions. This% article $ contains-contains-comes from; China Carbon Emissions Trading Network. The three common factors are climate, energy price and macroeconomic environment. The impact of climate change on carbon dioxide emissions is immediate. For example, in cold years, due to the increased demand for electricity and other energy sources, carbon dioxide emissions will increase significantly. Another important factor affecting carbon price is the price of other energy sources. The conversion of coal and oil into electricity and heat is still the largest industrial process in the world. Easy carbon experts said that from the financial crisis, it can be seen that with the decrease of industrial output, the price of carbon declined in 2008 and 2009, and gradually increased during the slow recovery of the world economy. The price of carbon is closely related to other energy sources. According to World Bank data, the price correlation between crude oil and EUA reached 82% in 2007 and 95% in 2008. The fourth is the price influencing factors of related products. The prices of various carbon products are highly correlated. According to experts of easy carbon, the carbon emission rights futures trading market has the characteristics of the traditional futures market, and there is a long-term equilibrium relationship between the futures prices and spot prices of EUA and CER, which influences each other. In contrast, EUA futures have a great influence on the spot and have a certain price discovery function, while CER is mainly affected by the spot price, which may be related to the fact that the primary transactions of CDM are mainly in the OTC market. At the same time, the price between EUA futures and CER futures is also highly correlated, and the price of EUA futures plays a guiding role in CER futures.
