Understanding carbon credits: A strategic lever for global ESG

As global regulatory frameworks become more demanding and stakeholder expectations intensify, carbon credits have emerged as one of the most widely discussed mechanisms in the context of corporate sustainability. Thus, for organizations seeking to achieve carbon neutrality, carbon credits represent both a strategic opportunity and a governance challenge.

However, despite their growing relevance, carbon credits remain widely misunderstood. Are they merely a license to pollute or a legitimate instrument within a well-designed carbon neutrality strategy? The answer depends entirely on how they are integrated into a broader ESG framework, the rigor of management procedures, and the transparency of reporting.

This article provides a comprehensive overview of carbon credits, the forces driving their rapid growth, and the challenges that must be addressed to ensure their credibility. Understanding this reality is a strategic imperative for leaders committed to creating sustainable value.

What are carbon credits, and how do they work?

A carbon credit is a tradable certificate that represents the reduction or removal of one metric ton of CO₂e. In compliance markets, emission allowances are used, which differ from the carbon credits typical of voluntary carbon markets. Organizations may acquire emission allowances as part of the compliance obligations imposed by regulatory authorities, as well as carbon credits in voluntary markets intended to offset residual greenhouse gas emissions.

The fundamental principle underlying carbon credits is simple: by creating financial value for emission reductions, markets incentivize investment in cleaner technologies, energy efficiency projects, reforestation initiatives, and other activities that remove or avoid greenhouse gas emissions. Each verified credit should represent a measurable reduction or avoidance of greenhouse gas emissions, depending on the underlying project type.

Compliance markets vs. voluntary markets

Carbon markets are structured into two main categories: compliance markets and voluntary markets, each with distinct objectives, mechanisms, and frameworks.

Compliance markets are established by regulatory authorities and impose mandatory limits on greenhouse gas emissions in specific sectors. In systems such as the European Union Emissions Trading System (EU ETS), organizations must hold emission allowances equal to their verified emissions. When they exceed their allocated limit, they must purchase additional allowances on the market, creating a direct economic incentive to reduce their carbon footprint.

In contrast, voluntary carbon markets allow organizations and other entities to acquire carbon credits outside any regulatory obligation. These credits represent verified emission reductions or removals generated by projects such as reforestation, renewable energy, or carbon capture technologies. They are primarily used to offset residual emissions within carbon neutrality strategies.

Although distinct, these two markets are gradually becoming more interconnected. The development of international mechanisms under Article 6 of the Paris Agreement is creating bridges between regulated systems and voluntary initiatives, creating opportunities for scale, but also additional challenges in terms of integrity, transparency, and the prevention of double-counting.

Key drivers of growth in the carbon credit market

Several converging forces explain the acceleration in demand for carbon credits across industries, geographies, and organizational sizes. Understanding these drivers is essential for leaders seeking to position their organizations strategically in the evolving sustainability landscape.

Regulatory pressure and policy framework

International frameworks such as the Paris Agreement have established a global architecture for emissions reduction. Article 6 of this agreement has been progressively operationalized since COP26, providing the basis for international trading of emission reductions between countries through bilateral cooperation mechanisms and a future centralized mechanism under the auspices of the United Nations. In recent years, multiple bilateral agreements have been established under Article 6.2, reflecting growing institutional momentum and countries’ interest in using carbon markets as a climate policy instrument.

At the regional level, the European Union’s Carbon Border Adjustment Mechanism (CBAM), which enters its definitive phase in January 2026, requires importers of carbon-intensive goods to obtain certificates reflecting the carbon cost of their production. India plans to launch its mandatory Carbon Credit Trading Scheme (CCTS) by mid-2026, covering nine carbon-intensive industrial sectors. These regulatory developments are helping create a global compliance infrastructure, making carbon management an operational necessity rather than just a strategic option.

Investor expectations and corporate net-zero commitments

Institutional investors are increasingly integrating ESG criteria into their decision-making processes. It is estimated that around 50% of global companies already have net-zero commitments, driving increased demand for credible carbon credits as part of their transition strategies. Organizations that cannot demonstrate a consistent approach to emissions management and offsetting face growing scrutiny from investors, rating agencies, and the broader financial community.

This pressure is not limited to large corporations. Mid-sized companies and various elements of the supply chain are also compelled to measure, manage, and report their carbon footprints with increasing rigor.

Integration of nature-based and technology-based solutions

Innovation in carbon reduction and removal is expanding the market’s supply side. Nature-based solutions (NbS), such as reforestation, afforestation, and sustainable land management, remain the most widely used approaches. However, technology-based solutions, including Direct Air Capture (DAC) and biochar, are transitioning from pilot phases to financially viable infrastructure, diversifying the landscape and creating new opportunities for organizations seeking high-integrity credits.

Addressing market challenges: Quality, transparency, and credibility

Despite its positive momentum, the carbon credit market faces significant challenges that organizations must manage carefully. The credibility of a carbon strategy depends directly on the quality and integrity of the credits used, and leaders must be aware of the risks that persist in this rapidly evolving market.

Offsets vs. removals: A critical distinction

An increasingly relevant distinction in the carbon market is the difference between offset credits and removal credits.

Offsets refer to emission reductions or avoidance, such as renewable energy or energy efficiency projects, which prevent new emissions from occurring. Removals, in contrast, involve the active removal of carbon dioxide from the atmosphere through nature-based solutions, such as reforestation, or technologies such as Direct Air Capture.

This distinction is fundamental to carbon neutrality strategies. While offsets can play a relevant role in the transition, there is a growing consensus that, in the long term, neutralizing residual emissions should primarily rely on removal solutions, given their direct contribution to reducing atmospheric carbon concentrations.

For business leaders, understanding this difference is essential to ensure the credibility of their climate strategies and to align with emerging best practices.

The quality imperative

Not all carbon credits are the same. The market has been affected by concerns regarding credit quality, including issues of additionality (whether the emission reduction would have occurred without the financial incentive), permanence (whether the sequestered carbon will remain stored over time), and leakage (whether the project shifts emissions to other geographies).

In response to these concerns, there has been a growing focus on high-integrity carbon credits—instruments that meet rigorous criteria for verification, transparency, and real climate impact. International initiatives such as the Integrity Council for the Voluntary Carbon Market (ICVCM) have been establishing principles and quality criteria, namely the Core Carbon Principles (CCPs), to strengthen trust in the voluntary market.

This evolution is translating into clearer differentiation in pricing and demand. High-quality credits, particularly those associated with removals, have been capturing significant premiums, while lower-integrity credits face increasing scrutiny and reduced liquidity. For organizations, this implies a clear shift: the carbon strategy should prioritize quality over volume and integrate robust project selection and evaluation criteria.

Verification standards and double-counting

Robust verification is essential to ensure that carbon credits represent genuine emission reductions. Certification standards such as the Verified Carbon Standard (VCS), developed by Verra, and the Gold Standard provide frameworks for project validation, but inconsistencies across jurisdictions persist. The risk of double-counting, where multiple parties claim the same emission reduction, has been an ongoing concern, particularly at the intersection of compliance and voluntary markets. Corresponding adjustment mechanisms under Article 6.2 of the Paris Agreement aim to address this risk, but implementation remains complex.

The risk of greenwashing

Perhaps the most significant reputational risk for organizations is the perception, or reality, of greenwashing. Acquiring carbon credits without demonstrating genuine efforts to reduce direct emissions can expose organizations to public criticism, legal action, and erosion of stakeholder trust. In recent years, several high-profile cases have highlighted the consequences of poorly managed carbon strategies, reinforcing the need for transparency, rigor, and alignment between statements and actions.

Carbon credits as part of a broader ESG strategy

For organizations committed to credible sustainability performance, carbon credits should never be positioned as a substitute for direct emission reductions. Instead, they should be integrated as a complementary mechanism within a clearly defined sustainability strategy that prioritizes operational decarbonization and uses offsets exclusively for residual impact.

The hierarchy of climate action

A well-structured corporate sustainability strategy follows a clear hierarchy, aligned with recognized frameworks such as the GHG Protocol and the Science Based Targets initiative (SBTi): first, measure and understand the organization’s carbon footprint (typically covering Scope 1, 2, and 3 emissions); second, reduce emissions at the source through operational improvements, energy efficiency, and the transition to renewable energy, including supply chain sustainability initiatives; third, only after exhausting reduction opportunities, offset residual emissions through high-quality carbon credits.

Integrating carbon management into sustainability reporting

As sustainability reporting frameworks evolve, from the European Sustainability Reporting Standards (ESRS) to the guidelines of the International Sustainability Standards Board (ISSB), organizations are expected to disclose not only their emissions performance but also their offsetting strategies, credit sourcing criteria, and governance mechanisms. A comprehensive sustainability report should articulate how carbon credits fit within the overall strategy, how their quality is assessed, and how progress is monitored over time. Credible reporting strengthens stakeholder trust and supports long-term value creation.

The role of continuous improvement in credible carbon strategies

Organizations that succeed in meeting their carbon and ESG commitments share a common characteristic: they approach sustainability not as a one-time initiative, but as part of their culture of continuous improvement. This approach is essential to ensure that carbon strategies remain effective, adaptive, and credible over time.

Credible carbon management requires structured execution, disciplined ESG governance, and the integration of sustainability performance into the organization’s management systems. It requires regular review cycles, transparent performance monitoring, and a culture that empowers teams at all levels to identify improvement opportunities and act on them.

Key benefits for organizations

Integrating carbon credits into a well-managed ESG strategy generates tangible benefits across multiple dimensions of organizational performance:

• Regulatory compliance and risk mitigation: proactive carbon management positions organizations ahead of evolving regulatory requirements, reducing the risk of penalties, border adjustments, and reputational damage.
• Investor confidence and access to capital: transparent carbon strategies strengthen ESG ratings and attract sustainability-focused investors seeking credible long-term commitments.
• Operational efficiency: the process of measuring and managing emissions often reveals significant opportunities for waste reduction, energy savings, and process optimization.
• Stakeholder trust: clear and honest communication about carbon performance, including the role and limitations of offsets, builds trust with customers, employees, and communities.
• Competitive advantage: organizations that embed sustainability into their operations are better positioned to respond to market changes, customer preferences, and regulatory shifts.
• Long-term value creation: credible sustainability strategies contribute to organizational resilience, brand equity, and the ability to attract and retain talent.

Conclusion: From compliance to strategic transformation

Carbon credits are neither a panacea nor a distraction. When managed effectively and integrated into a coherent ESG strategy, they constitute a legitimate and valuable mechanism to accelerate the transition to a low-carbon economy. However, their value depends entirely on the quality of execution, the transparency of reporting, and the depth of commitment to actual emission reductions.

For leaders and decision-makers, the message is clear: carbon management cannot be delegated to a single department nor reduced to a procurement exercise. It requires cross-functional alignment, operational rigor, and a culture of continuous improvement that connects sustainability goals to measurable business outcomes.

Organizations that will thrive in this new context are those that treat carbon strategy as a catalyst for operational transformation, not merely as a compliance obligation. By embedding sustainability into the fabric of their operations, governance, and culture, companies will build the resilience, credibility, and competitive advantage required to create lasting value in an increasingly demanding world.
