Carbon Credits: How Global Commitments Evolved From Kyoto To Paris

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:

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:,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:

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:

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.
