From EU ETS to CDP: Deep Dive into European Carbon Emissions Trading Strategies
The world today is facing unprecedented climate change challenges, and global greenhouse gas emissions are one of the main causes of global warming. To address this crisis, governments and international organizations worldwide are seeking effective emission reduction strategies. Against this backdrop, 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 businesses to seek the most economical and effective emission reduction methods. This market mechanism helps internalize environmental costs, prompting businesses and organizations to pay more attention to their carbon footprint, thereby driving the entire society towards a lower-carbon future.
Global Carbon Emission Trends
The "2023 Carbon Emissions Review Report" released 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 new historical high of 37.4 billion tons. However, this growth rate is 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 slow down the growth of global carbon emissions to the slowest rate since the Great Depression. Without the widespread adoption of key clean energy technologies such as wind power, solar power, nuclear energy, heat pumps, and electric vehicles, carbon emissions would be three times higher than they are currently.
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. In addition, the Carbon Disclosure Project (CDP) actively encourages businesses and governments worldwide to disclose their environmental impact, evaluating these organizations' climate change response strategies and specific environmental protection actions through detailed questionnaires, thereby promoting the public disclosure of related climate risks and opportunities.
The EU ETS covers 28 EU member states, as well as Iceland, Liechtenstein, and Norway. Its main objective is to achieve greenhouse gas emission reductions, especially carbon dioxide, through market mechanisms. Since its implementation in 2005, the system has operated for over 8 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, first determining an overall carbon emission cap, and then allocating or selling 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 an enterprise 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 businesses to adopt greener production methods through economic means, thereby reducing overall carbon emissions. EU ETS carbon prices fluctuate due to factors including policy changes, market forces, and global trends. As shown in the figure below, the carbon price first soared to 100 euros per ton in March 2023, reflecting the market's active response to carbon reduction pressure.

The European carbon credit trading system is primarily managed by the European Commission, ensuring the overall coordination and operation of the system. Member states are responsible for managing their national allowance allocations and supervising corporate compliance with regulations. CDP, as a non-governmental organization, is dedicated to encouraging global businesses and governments to disclose their environmental impact. Through detailed questionnaires, CDP assesses enterprises' climate change response strategies and 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 evaluation of other environmental issues such as water resources and forest protection. Enterprises must assess the direct and indirect impacts of their business activities on the environment and formulate corresponding response strategies. This comprehensive environmental impact assessment helps enterprises identify risks and opportunities and promote 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 critical, and transparent carbon emission disclosure and effective carbon market mechanisms are 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 carbon market efficiency. 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 that are tailored to national characteristics can be designed. Furthermore, CDP's disclosure standards not only help businesses and governments understand their 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 businesses to take more proactive climate action.
Through systems and standards such as 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 impetus for all sectors to continue deepening their response to climate change. They enable businesses and governments to remain engaged, contributing their efforts to global climate action. Actively understanding and adhering to these international carbon markets and environmental information disclosure regulations is not only a concrete expression of corporate social responsibility but also a key to long-term business success and sustainable development. Therefore, active participation in and response to these international initiatives will help businesses gain a favorable position and open up new business opportunities in the tide of global green transformation.
