From EU ETS to CDP: In-depth Insights into European Carbon Emission Trading Strategies
The world today faces unprecedented challenges due to climate change, with global greenhouse gas emissions being one of the main causes of global warming. To address this crisis, governments and international organizations worldwide are seeking effective strategies to reduce emissions. In this context, the carbon credit trading system has emerged, serving not only as an economic incentive but also as a crucial tool for achieving emission reduction targets. By setting an overall cap on carbon emissions and allowing the market to trade freely within this framework, carbon credit trading encourages companies to find the most economically effective methods for reducing emissions. This market mechanism helps to internalize environmental costs, prompting companies and organizations to pay more attention to their carbon footprint, and thus driving society as a whole toward a lower-carbon future.
Global Carbon Emission Trends
The "2023 Carbon Emissions Review" report published by the International Energy Agency (IEA) in March 2024 shows that global energy-related carbon emissions in 2023 increased by approximately 1.1% (410 million tons) compared to the previous year, reaching a historical high of 37.4 billion tons. However, this growth rate was lower than the 1.3% (490 million tons) increase in 2022. Between 2019 and 2023, the growth rate of clean energy was twice that of fossil fuels, which helped to slow down the growth rate of global carbon emissions, making it the slowest growth rate since the Great Depression. Without the widespread adoption of key clean energy technologies such as wind power, solar energy, nuclear energy, heat pumps, and electric vehicles, carbon emissions would be three times higher than they are today.
Carbon Credit Trading and Environmental Protection
Currently, the global carbon emissions trading market primarily involves countries such as the European Union, the United Kingdom, Australia, the United States, and Japan. Among these, the European Emissions Trading Scheme (EU ETS) is the largest carbon emissions trading market globally. Furthermore, the Carbon Disclosure Project (CDP) actively encourages global companies and governments to disclose their environmental impact, using detailed questionnaires to assess these entities' strategies for responding to climate change and specific environmental protection actions, thereby promoting the public disclosure of relevant climate risks and opportunities.
The EU ETS covers the 28 member states of the European Union, as well as Iceland, the Principality of Liechtenstein, and Norway. Its main objective is to reduce greenhouse gas emissions, particularly carbon dioxide, through market mechanisms. Since its implementation in 2005, the system has been operating for over eight years, covering approximately 45% of European carbon emissions, and has significantly promoted investment in and development of clean technologies. The EU ETS employs a "cap-and-trade" mechanism, which first sets an overall cap on carbon emissions and then allocates or sells carbon emission allowances to large emitters. Each allowance represents the right to emit one ton of carbon dioxide or an equivalent amount of other greenhouse gases. If a company emits more than its allocated allowances, it must purchase additional allowances; if it has surplus allowances, it can sell them on the market or save them for the next period. Carbon credits are primarily traded publicly on platforms such as the European Energy Exchange, with market prices determined by supply and demand. This mechanism aims to incentivize companies to adopt greener production methods through economic means, thereby reducing overall carbon emissions. The EU ETS carbon price fluctuates due to factors such as policy changes, market forces, and global trends. As shown in the figure below, the carbon price first surged to 100 euros per ton in March 2023, reflecting the market's proactive response to pressure for carbon reduction.

The European carbon trading system is primarily managed by the European Commission, ensuring overall coordination and operation of the system. Member states are responsible for managing their national allowance allocation and overseeing companies' compliance with regulations. CDP, as a non-governmental organization, is dedicated to encouraging global companies and governments to disclose their environmental impact. Through detailed questionnaires, CDP assesses companies' strategies for responding to climate change and their environmental protection actions, and promotes these entities to publicly disclose their climate change-related risks and opportunities. CDP not only focuses on carbon emission disclosure but also covers the assessment of other environmental issues such as water resources and forest protection. Companies must assess the direct and indirect environmental impacts of their business activities and formulate corresponding response strategies. This comprehensive environmental impact assessment helps companies identify risks and opportunities, promoting sustainable development.
The implementation of these systems not only demonstrates the international community's recognition of the severity of climate change but also reflects the importance of global cooperation in seeking sustainable environmental solutions. As global greenhouse gas emissions continue to rise, international cooperation becomes even more crucial, with transparent carbon emission disclosure and effective carbon market mechanisms at the core of this cooperation. The successful operation of the EU ETS and CDP provides valuable experience, particularly in promoting technological innovation and enhancing the efficiency of carbon markets. These experiences can serve as a reference for other countries and regions, especially for those that are developing and planning to implement their own carbon trading systems. By learning from international experience and combining it with local realities, more effective carbon emission management strategies tailored to national characteristics can be designed. Furthermore, CDP's disclosure standards not only help companies and governments understand their own carbon footprint but also provide investors and policymakers with a basis for evaluating corporate climate risks and opportunities. This transparency is a key factor in driving global capital towards more sustainable investments and an important mechanism for incentivizing companies to take more proactive climate action.
Through systems and standards like the EU ETS and CDP, a common global force for carbon reduction and environmental protection has been formed. They establish a framework for continuously advancing climate action, constantly stimulating innovative solutions, and providing momentum for all sectors to deepen their response to climate change. This ensures continuous participation from businesses and governments, contributing their part to global climate action. By actively understanding and adhering to these international carbon markets and environmental information disclosure regulations, companies not only fulfill their social responsibilities but also secure long-term business success and achieve sustainable development. Therefore, active participation and responsiveness to these international initiatives will help companies seize a favorable position and unlock new business opportunities in the tide of global green transformation.
