How Is Global Carbon Governance Reshaping Corporate Carbon Reduction Pathways?

Global warming not only threatens biodiversity, but also directly affects human health and well-being. As major sources of greenhouse gas emissions, enterprises play a key role in carbon reduction. However, due to insufficient short-term returns on green investment, many enterprises lack the incentive to disclose a "low-carbon transition roadmap," which poses challenges to achieving net-zero goals. A study published in *Frontiers in Environmental Science* reviewed carbon governance experiences in typical countries (regions) worldwide, constructed a multidimensional impact framework for corporate carbon reduction, and proposed a specific roadmap. This study provides practical references for enterprises in balancing environmental footprint and value growth.

Industry Background: Global Carbon Governance Framework and Emission Landscape

Since the establishment of the United Nations Framework Convention on Climate Change in 1994, international cooperation on climate action has been continuously strengthened. The Kyoto Protocol and the Paris Agreement have successively become core documents of global climate policy. In November 2021, China and the United States, the largest carbon emitters, issued a joint declaration at the Glasgow Climate Conference, pledging to strengthen cooperation, reduce carbon emissions, and eliminate global illegal deforestation, jointly promoting the achievement of the Paris Agreement's net-zero goals.

In this context, the emissions trading system (ETS) has become a key decarbonization tool. The ETS is a quota-based "cap-and-trade" mechanism that connects governments and enterprises. According to the ICAP 2022 report, the global distribution of ETS is uneven: the EU's carbon trading mechanism is the most mature, while most countries are still in the early stages of development.

From an emissions data perspective, between 1995 and 2020, the United States and China were the two largest carbon emitters globally. The United States emitted approximately 5 billion tons of carbon annually; China, due to rapid industrialization and urbanization, ranked first globally in total carbon emissions by 2020. Such a massive emission scale means that corporate sector emission reductions will directly affect the achievement of global climate goals.

Current Developments: Multidimensional Pressures on Corporate Carbon Reduction

Despite growing policy pressure, emission reduction progress at the corporate level remains lagging. The study points out that some enterprises' net-zero targets have very limited coverage. For example, the 2050 net-zero target set by ACI Europe only covers buildings and ground operations, yet excludes aircraft emissions, which account for 98% of corporate carbon emissions. This practice of "selective disclosure" causes a serious disconnect between nominal emission reduction commitments and actual emission behavior.

In addition, some enterprises beautify their environmental image through "greenwashing" to gain financial support from investment institutions and shareholders. However, once greenwashing is exposed, the trust of investors and consumers will be lost, causing irreversible damage to corporate reputation and value. This indicates that enterprises lacking substantive emission reduction actions are facing increasingly growing reputational and regulatory risks.From the perspective of driving forces, government environmental regulation is an important external factor promoting corporate carbon emission reduction. A growing number of studies have found that government pressure can effectively overcome organizational inertia and complement internal corporate governance mechanisms. The Porter hypothesis also points out that appropriate environmental regulation can force enterprises to invest in green technology innovation, and in the long run, the benefits may exceed the costs of environmental compliance.

Impact on the Energy System and Investment

The deepening of corporate carbon emission reduction actions is having a structural impact on the global energy system. First, the improvement of carbon trading mechanisms internalizes carbon costs, pushing enterprises to shift from traditional fossil fuels to clean electricity and renewable energy in their energy choices. This shift will directly drive demand for photovoltaics, wind power, and energy storage systems, promoting the low-carbon transformation of the power structure.

Second, the increased application of green technologies will change corporate energy consumption patterns, for example, by reducing carbon emissions through energy efficiency improvements, electrification upgrades, and hydrogen energy substitution. These actions not only reduce end-use carbon emissions but also create stable market demand for upstream clean energy industries.

From an investment perspective, corporate carbon reduction pressure is reshaping capital flows. Institutional investors and ESG funds are increasingly focusing on corporate carbon performance, and the quality of carbon disclosure has become an important reference for investment decisions. Enterprises that can clearly present emission reduction roadmaps and quantify reduction targets are more likely to obtain green financing, while enterprises lagging in emission reduction actions may face the risk of rising financing costs.

Challenges Ahead

Despite continuously increasing external pressure, enterprises still face multiple obstacles in advancing carbon emission reduction.

First, short-term cost pressure. Traditional fossil energy prices are relatively low, and significantly reducing their use will push up operating costs in the short term, increasing financial risk. This is the main reason why many enterprises are reluctant to carry out substantial carbon emission reduction.

Second, incomplete governance structures. Some enterprises have not yet incorporated carbon targets into the performance appraisals of boards of directors and senior management, making it impossible to effectively implement emission reduction responsibilities in specific departments.

Third, cash flow constraints. The low-carbon transition requires substantial upfront capital investment, while the return cycle for green investment is relatively long. Many enterprises, especially small and medium-sized enterprises, face insufficient cash flow and find it difficult to sustain continuous technological transformation and process upgrades.

Fourth, insufficient transparency. The lack of unified standards for corporate carbon information disclosure makes it difficult for investors and policymakers to assess real emission reduction progress, and also increases the space for "greenwashing" behavior.

Future Outlook: Corporate Carbon Emission Reduction Roadmap

To address the above challenges, the study proposes a four-dimensional corporate carbon emission reduction roadmap, providing a reference for corporate transformation over the next 5 to 20 years.

First, actively participate in carbon emission trading systems. Enterprises should regard carbon trading as a strategic tool, reducing compliance costs while exploring new revenue sources through quota management, carbon asset operations, and carbon credit procurement. As the global ETS coverage expands, enterprises that position themselves early in the carbon market will gain a competitive advantage.Second, scale up the application of green technologies. Enterprises should embed green technology innovation throughout the entire production process to reduce dependence on high-emission processes. The application of digital, intelligent, and circular economy technologies will help enterprises cut carbon emissions while improving efficiency.

Third, improve corporate governance structures. Integrate carbon reduction targets into the corporate governance framework, establish a dedicated sustainable development committee, and link carbon performance to executive compensation. A transparent carbon information disclosure mechanism is the foundation for winning the trust of investors and policymakers.

Fourth, ensure cash flow support for the low-carbon transition. Enterprises need to establish green financial mechanisms, raise funds for transition projects through instruments such as green bonds and sustainability-linked loans, and use carbon trading revenue to form a positive cash flow cycle.

In the long run, global carbon governance is deepening from "national commitments" to "corporate implementation." Enterprises that can integrate carbon reduction into their core strategies will take the lead in the energy transition. Conversely, enterprises that lag behind policy and market changes will face systemic risks of stranded assets and reputational damage.

Under the goal of net-zero emissions, no enterprise can stay on the sidelines. Carbon governance is no longer a purely environmental issue, but a key variable concerning the restructuring of the global energy system, the repricing of capital, and the reshaping of economic competitiveness.
