The rise in global temperatures is a concern that many are taking seriously. Governments, big companies, small businesses, and everyday people are looking for ways to reduce greenhouse gas emissions to lessen climate change risks. One method that’s gaining a lot of attention is using carbon credits. This idea helps provide financial rewards for those who cut down on emissions and support the growth of clean energy sources. This article is the 5th part of our new series based on our 2023 Climate Change and Carbon Markets Annual Report. The series so far includes:
- Climate Change Basics: Causes, Impacts and Carbon Credit Solutions
- Carbon Credits Are Essential For Climate Action
- Carbon Credits For Fighting Climate Change
- Changing Fuels to Combat Climate Change
In this post, we’re going to explore the journey of carbon credits from the start with the Kyoto Protocol to now with the Paris Agreement. We’ll look at how global agreements on climate have evolved and how carbon credits play a crucial part in these. Through this discussion, we hope to give a clear picture of how the world is working together to create a sustainable environment for the future.
The Kyoto Protocol: Setting the Stage for Carbon Credits
The Kyoto Protocol, established under the United Nations Framework Convention on Climate Change (UNFCCC) in 1997, marked the inception of formalized global efforts to curb greenhouse gas (GHG) emissions. This landmark treaty set forth binding emissions reduction targets for 37 industrialized nations and the European Union, aiming to reduce emissions to 5% below 1990 levels between 2008 and 2012. A subsequent amendment in 2012 extended these targets to 2013-2020. Central to the Kyoto Protocol was the innovative concept of carbon credits, designed to provide economic incentives for emissions reductions. The Protocol introduced Emissions Trading, the Clean Development Mechanism (CDM), and Joint Implementation (JI), laying the foundation for the global carbon credit framework (see: https://unfccc.int/news/kyoto-protocol-paves-the-way-for-greater-ambition-under-paris-agreement#:~:text=,like%20Germany%20by%2030%20percent).
Key facts:
- The Kyoto Protocol committed developed countries to emissions reduction targets of 5% below 1990 levels between 2008-2012. This was later extended to 2013-2020 with an amended treaty.
- The innovative mechanisms introduced included Emissions Trading, CDM, and JI which provided the blueprint for carbon credits trading.
Paris Agreement: A New Dawn in Global Climate Cooperation
The Paris Agreement, adopted in 2015, emerged as a robust successor to the Kyoto Protocol, reflecting a global shift towards more inclusive and ambitious climate action. Unlike the Kyoto Protocol, which placed binding targets on developed countries alone, the Paris Agreement encourages all nations to contribute towards global emissions reduction. This inclusive framework aims to limit global temperature rise to well below 2°C, with an ambition of 1.5°C above pre-industrial levels. The Paris Agreement introduced the Sustainable Development Mechanism (SDM), poised to replace the Kyoto Protocol’s Clean Development Mechanism (CDM), signifying a transformation in the realm of carbon credits and setting a new trajectory for global environmental strategies (see: https://greencoast.org/kyoto-protocol-vs-paris-agreement).
Key facts:
- The Paris Agreement set a more ambitious goal of limiting global warming to 1.5°C compared to the Kyoto Protocol’s 2°C target.
- It has a universal framework encouraging all countries to contribute, unlike the Kyoto Protocol’s binding targets just for developed nations.
- Introduced the SDM to replace the CDM, reflecting an evolution in carbon credits post-Kyoto.
Why Some Countries Opted Out: Economic and Strategic Considerations
The Kyoto Protocol faced resistance from some major emitting countries due to concerns surrounding economic competitiveness and equity. The U.S., citing potential economic drawbacks and the lack of binding commitments on developing countries, chose not to ratify the Protocol. Canada withdrew in 2011, expressing concerns over the Protocol’s ability to effectively address global emissions without the participation of major emitters like the U.S. and China. These decisions underscored the complex interplay of economic, strategic, and environmental considerations that influence international climate agreements and the operationalization of carbon credits (see: https://kleinmanenergy.upenn.edu/news-insights/lessons-learned-from-kyoto-to-paris).
Key facts:
- The U.S. and Canada opted out due to concerns over economic impacts and equity without developing nations’ commitments.
- Highlights the strategic considerations alongside environmental ones in climate agreements.
Carbon Credits – A Mechanism to Meet Targets
The Kyoto Protocol introduced pioneering mechanisms like Emissions Trading, the Clean Development Mechanism (CDM), and Joint Implementation (JI) to help nations meet their emissions reduction targets. These mechanisms provided the blueprint for the evolution of the carbon credit system, allowing for the trading of emission allowances and fostering international collaboration on carbon sequestration projects. The Paris Agreement further refined these mechanisms, introducing the Sustainable Development Mechanism (SDM) to build upon the successes and lessons learned from the Kyoto-era mechanisms, thereby enhancing the global carbon credit framework.
Key facts:
- Emissions Trading, CDM, and JI were introduced under Kyoto as innovative ways to meet reduction targets.
- Paris Agreement’s SDM builds on these mechanisms to further improve the carbon credits system.
The Decline of the CDM: Transitioning to a New Era
With the advent of the Paris Agreement, the Clean Development Mechanism (CDM) saw a decline in prominence as the Sustainable Development Mechanism (SDM) emerged. This transition reflects the global community’s adaptive approach to evolving environmental challenges. The SDM, with its broader scope and enhanced flexibility, aims to address the shortcomings of the CDM, offering a more robust framework for carbon credit initiatives. The shift from CDM to SDM signifies a continued evolution in the mechanisms governing carbon credits, aligning with the ambitious global climate goals set forth by the Paris Agreement.
Key facts:
- The CDM is being replaced by the more robust SDM under Paris reflecting an adaptive approach.
- SDM has a wider scope and flexibility compared to CDM.
Challenges in Participation: Navigating Global Climate Dynamics
The participation challenges faced by the Kyoto Protocol highlight the complexities inherent in global climate agreements. Major emitters like the U.S. and China’s reluctance to commit to binding emissions reduction targets under the Kyoto Protocol underscored the need for a more inclusive approach. The Paris Agreement, with its universal framework for climate action, addresses some of these challenges by encouraging all nations, regardless of their economic status, to contribute towards global emissions reduction. However, the nuances of national and global priorities continue to influence the level of participation and commitment to carbon credit initiatives.
Key facts:
- Universal participation under Paris was designed to address the lack of major emitters’ commitment under Kyoto.
- National interests still impact countries’ levels of commitment to climate agreements.
The Role of the International Transaction Log (ITL): Ensuring Transparency and Accountability
The International Transaction Log (ITL) plays a crucial role in the operationalization of carbon credits by ensuring transparency, accountability, and efficiency in carbon credit transactions. Established by the Secretariat of the Conference of Parties, the ITL meticulously records carbon credit transactions, preventing potential issues like double-counting of reductions or the sale of identical credits multiple times. The ITL, by bridging national emissions trading registries and the UNFCCC, exemplifies the global commitment to a transparent and accountable carbon credit system, underpinning the credibility of international emissions trading initiatives.
Key facts:
- The ITL prevents double-counting and ensures transparency in carbon credits trading.
- It bridges national registries and UNFCCC to enable international cooperation.
Risks and Mitigation in Carbon Credit Projects: Ensuring Viability and Sustainability
Carbon credit projects, inherent with regulatory and market risks, necessitate robust mitigation strategies to ensure their viability and sustainability. The complexities of regulatory approvals, monitoring actual emissions, and navigating volatile market dynamics pose challenges to carbon credit projects. Leveraging approved CDM technologies and entering into long-term fixed-price contracts can significantly reduce these risks. The evolving carbon credit framework, transitioning from CDM to SDM under the Paris Agreement, reflects a continued effort to address these risks and enhance the sustainability of carbon credit projects.
Key facts:
- Regulatory and market risks pose viability challenges for carbon credit projects.
- CDM methodologies and long-term contracts help mitigate risks.
Controversies in Land Use Projects: Navigating Carbon Sequestration Challenges
Land use projects under the Kyoto Protocol aimed at GHG removals and emissions reductions through activities like afforestation and reforestation. However, they faced resistance due to challenges in estimating and tracking GHG removals over extended periods. The complexities of measuring carbon sequestration, particularly in vast forested areas, underscore the controversies and challenges inherent in the carbon credits domain. The Paris Agreement, with its enhanced framework for carbon credit initiatives, offers avenues to address some of these challenges, promoting a more robust and transparent approach to land use projects within the carbon credits framework.
Key facts:
- Estimating and monitoring carbon sequestration from land use projects is complex.
- Caused controversies under Kyoto but Paris Agreement provides scope to improve.
Conclusion – Carbon Credits and the Evolution of Global Climate Strategy
The journey of carbon credits, from the early days of the Kyoto Protocol to the transformative era of the Paris Agreement, offers a window into the world’s evolving approach to climate change mitigation. The innovative mechanisms introduced under these agreements have played a pivotal role in shaping the global carbon credit framework. As nations continue to navigate the complex landscape of global climate cooperation, understanding the intricacies of carbon credits remains pivotal in the collective quest for a sustainable future. Through the lens of carbon credits, we witness the global community’s adaptive strategies in the face of evolving environmental challenges, charting a course towards a more sustainable and resilient global climate framework.

A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
Carbon Footprint
Industries with the biggest nature footprints and what their decarbonisation looks like
A corporate carbon footprint is never just an accounting figure. It maps onto real ecosystems. Before a product leaves the factory gate, something on the ground has already paid the cost. A forest has been converted. A river has been depleted. A patch of savannah that was once home to dozens of species now grows a single crop in every direction.
More than 60 global companies, including Apple, Amazon, BYD, Salesforce, Mars, and Schneider Electric, are pushing back against proposed changes to global emissions reporting rules. The group is calling for more flexibility under the Greenhouse Gas Protocol (GHG Protocol), the most widely used framework for measuring corporate carbon footprints.
The companies submitted a joint statement asking that new requirements, especially those affecting Scope 2 emissions, remain optional rather than mandatory. Their letter stated:
“To drive critical climate progress, it’s imperative that we get this revision right. We strongly urge the GHGP to improve upon the existing guidance, but not stymie critical electricity decarbonization investments by mandating a change that fundamentally threatens participation in this voluntary market, which acts as the linchpin in decarbonization across nearly all sectors of the economy. The revised guidance must encourage more clean energy procurement and enable more impactful corporate action, not unintentionally discourage it.”
The debate comes at a critical time. Corporate climate disclosures now influence trillions of dollars in capital flows, while stricter reporting rules are being introduced across major economies.
The Rulebook for Carbon: What the GHG Protocol Is and Why It’s Being Updated
The Greenhouse Gas Protocol is the world’s most widely used system for measuring corporate emissions. It is used by over 90% of companies that report greenhouse gas data globally, making it the foundation of most climate disclosures.
It divides emissions into three categories:
- Scope 1: Direct emissions from operations
- Scope 2: Emissions from purchased electricity
- Scope 3: Emissions across the value chain
The current Scope 2 rules were introduced in 2015, but energy markets have changed since then. Renewable energy has expanded, and companies now play a major role in funding clean power.
Corporate buyers have already supported more than 100 gigawatts (GW) of renewable energy capacity globally through voluntary purchases. This shows how influential the current system has been.
The GHG Protocol is now updating its rules to improve accuracy and transparency. The revision process includes input from more than 45 experts across industry, government, and academia, reflecting its global importance.
Scope 2 Shake-Up: The Battle Over Real-Time Carbon Tracking
The proposed update would shift how companies report electricity emissions. Instead of using flexible systems like renewable energy certificates (RECs), companies would need to match their electricity use with clean energy that is:
- Generated at the same time, and
- Located in the same grid region.
This is known as “24/7” or hourly or real-time matching. It aims to reflect the actual impact of electricity use on the grid. Companies, including Apple and Amazon, say this shift could create challenges.
According to industry feedback, stricter rules could raise energy costs and limit access to renewable energy in some regions. It can also slow corporate investment in new clean energy projects.
The concern is that many markets do not yet have enough renewable supply for real-time matching. Infrastructure for tracking hourly emissions is also still developing.
This creates a key tension. The new rules could improve accuracy and reduce greenwashing. But they may also make it harder for companies to scale clean energy quickly.
The outcome will shape how companies measure emissions, invest in renewables, and meet net-zero targets in the years ahead.
Why More Than 60 Companies Oppose the Changes
The companies argue that stricter rules could slow climate progress rather than accelerate it. Their main concern is cost and feasibility. Many regions still lack enough renewable energy to support real-time matching. For global companies, aligning energy use across different grids is complex.
In their joint statement, the group warned that mandatory changes could:
- Increase electricity prices,
- Reduce participation in voluntary clean energy markets, and
- Slow investment in renewable energy projects.
They argue that current market-based systems, such as RECs, have helped scale clean energy quickly over the past decade. Removing flexibility could weaken that momentum.
This reflects a broader tension between accuracy and scalability in climate reporting.
Big Tech Pushback: Apple and Amazon’s Climate Progress
Despite their push for flexibility, both companies have made measurable progress on emissions reduction.
Apple reports that it has reduced its total greenhouse gas emissions by more than 60% compared to 2015 levels, even as revenue grew significantly. The company is targeting carbon neutrality across its entire value chain by 2030. It also reported that supplier renewable energy use helped avoid over 26 million metric tons of CO₂ emissions in 2025 alone.
In addition, about 30% of materials used in Apple products in 2025 were recycled, showing a shift toward circular manufacturing.
Amazon has also set a net-zero target for 2040 under its Climate Pledge. The company is one of the world’s largest corporate buyers of renewable energy and continues to invest heavily in clean power, logistics electrification, and low-carbon infrastructure.
Both companies argue that flexible accounting frameworks have supported these investments at scale.
The Bigger Challenge: Scope 3 and Digital Emissions
The debate over Scope 2 reporting is only part of a larger issue. For most large companies, Scope 3 emissions account for more than 70% of total emissions. These include supply chains, product use, and outsourced services.
In the technology sector, emissions are rising due to:
- Data centers,
- Cloud computing, and
- Artificial intelligence workloads.
Global data centers already consume about 415–460 terawatt-hours (TWh) of electricity per year, equal to roughly 1.5%–2% of global power demand. This figure is expected to increase sharply. The International Energy Agency estimates that data center electricity demand could double by 2030, driven largely by AI.
This creates a major reporting challenge. Even with cleaner electricity, total emissions can rise as digital demand grows.
Climate Reporting Rules Are Tightening Globally
The pushback comes as climate disclosure requirements are expanding and becoming more standardized across major economies. What was once voluntary ESG reporting is steadily shifting toward mandatory, audit-ready climate transparency.
In the European Union, the Corporate Sustainability Reporting Directive (CSRD) is now active. It requires large companies and, later, listed SMEs, to share detailed sustainability data. This data must match the European Sustainability Reporting Standards (ESRS). This includes granular reporting on emissions across Scope 1, 2, and increasingly Scope 3 value chains.
In the United States, the Securities and Exchange Commission (SEC) aims for mandatory climate-related disclosures for public companies. This includes governance, risk exposure, and emissions reporting. However, some parts of the rule face legal and political scrutiny.
The United Kingdom has included climate disclosure through TCFD requirements. Now, it is moving toward ISSB-based global standards to make comparisons easier. Similarly, Canada is progressing with ISSB-aligned mandatory reporting frameworks for large public issuers.
In Asia, momentum is also accelerating. Japan is introducing the Sustainability Standards Board of Japan (SSBJ) rules that match ISSB standards. Meanwhile, China is tightening ESG disclosure rules for listed companies through updates from its securities regulators. Singapore has also mandated climate reporting for listed companies, with phased Scope 3 expansion.
A clear trend is forming across jurisdictions: climate disclosure is aligning with ISSB global standards. There’s a growing focus on assurance, comparability, and transparency in value-chain emissions.
This regulatory tightening raises the bar significantly for corporations. The challenge is clear. Companies must:
- Align with multiple evolving disclosure regimes,
- Ensure emissions data is verifiable and auditable, and
- Expand reporting across complex global supply chains.
Balancing operational growth with compliance is becoming increasingly complex as climate regulation converges and intensifies worldwide.
A Turning Point for Global Carbon Accounting
The outcome of this debate could shape global carbon accounting standards for years.
If stricter rules are adopted, emissions reporting will become more precise. This could improve transparency and reduce greenwashing risks. However, it may also increase compliance costs and limit flexibility.
If the proposed changes remain optional, companies may continue using current accounting methods. This could support faster clean energy investment, but may leave gaps in reporting accuracy.
The new rules could take effect as early as next year, making this a near-term decision for global companies.
The push by Apple, Amazon, and other companies highlights a key tension in climate strategy. On one side is the need for accurate, real-time emissions reporting. On the other is the need for flexible systems that support large-scale clean energy investment.
As digital infrastructure expands and energy demand rises, how emissions are measured will matter as much as how they are reduced. The next phase of climate action will depend not just on targets—but on the systems used to track them.
