CCS in the Context of Global Climate Agreements

Carbon capture and storage (CCS) is a critical technology in the fight against climate change. It involves capturing carbon dioxide (CO2) emissions from power plants and industrial facilities, transporting it to a storage site, and securely storing it underground. CCS has gained significant attention in recent years as a potential solution to reduce greenhouse gas emissions and mitigate the impacts of climate change. In the context of global climate agreements, CCS plays a crucial role in achieving the ambitious emission reduction targets set by countries around the world. This article explores the importance of CCS in the context of global climate agreements and examines its potential benefits and challenges.

The Role of CCS in Global Climate Agreements

Global climate agreements, such as the Paris Agreement, aim to limit global warming to well below 2 degrees Celsius above pre-industrial levels. To achieve this goal, countries need to significantly reduce their greenhouse gas emissions. While renewable energy sources and energy efficiency measures are crucial in this transition, they alone may not be sufficient to achieve the required emission reductions. CCS can play a vital role in bridging the gap between current emission levels and the targets set by global climate agreements.

CCS enables the continued use of fossil fuels, such as coal and natural gas, while reducing their carbon footprint. By capturing and storing CO2 emissions, CCS can help power plants and industrial facilities achieve deep emission cuts. This technology can be particularly valuable in sectors where decarbonization options are limited, such as heavy industries like cement and steel production.

Furthermore, CCS can also facilitate the deployment of negative emissions technologies, such as bioenergy with carbon capture and storage (BECCS). BECCS involves growing biomass, such as trees or crops, and using it as a fuel source for power generation. The CO2 emitted during the combustion process is then captured and stored underground. This process effectively removes CO2 from the atmosphere, contributing to negative emissions. The integration of CCS with BECCS can help offset emissions from sectors that are challenging to decarbonize, such as aviation and shipping.

The Benefits of CCS in Global Climate Agreements

CCS offers several benefits in the context of global climate agreements:

  • Significant emission reductions: CCS has the potential to achieve substantial emission reductions by capturing and storing CO2 emissions from power plants and industrial facilities. This technology can help countries meet their emission reduction targets and contribute to the global effort to combat climate change.
  • Preservation of energy security: CCS allows for the continued use of fossil fuels, which are still a significant part of the global energy mix. By reducing the carbon footprint of fossil fuel-based power generation, CCS can help maintain energy security while transitioning to a low-carbon economy.
  • Economic opportunities: The development and deployment of CCS technologies can create new economic opportunities. CCS projects require skilled labor, engineering expertise, and infrastructure development, which can stimulate local economies and create jobs.
  • Enhanced competitiveness: CCS can help industries remain competitive in a carbon-constrained world. By reducing their carbon emissions, companies can avoid potential carbon pricing costs and maintain their market position.
  • Climate resilience: CCS can contribute to climate resilience by reducing the concentration of CO2 in the atmosphere. By storing CO2 underground, CCS helps prevent its release into the atmosphere, thereby mitigating the impacts of climate change.

Challenges and Limitations of CCS

While CCS offers significant benefits, it also faces several challenges and limitations:

  • Cost and financing: CCS projects are currently expensive to implement, making them economically challenging. The high upfront costs of CCS infrastructure, including capture, transport, and storage, pose financial barriers to widespread deployment. Governments and private investors need to provide financial incentives and support to make CCS economically viable.
  • Public acceptance and perception: CCS projects often face public opposition due to concerns about the safety and long-term viability of storing CO2 underground. Public acceptance and perception play a crucial role in the successful deployment of CCS technologies. Effective communication and engagement with local communities are essential to address concerns and build trust.
  • Regulatory and legal frameworks: The development and deployment of CCS technologies require robust regulatory and legal frameworks. Clear guidelines and standards are needed to ensure the safe and secure storage of CO2 underground. International cooperation is also necessary to address legal and liability issues associated with cross-border transportation and storage of CO2.
  • Infrastructure requirements: CCS infrastructure, including pipelines for CO2 transport and storage sites, requires significant investment and planning. The availability of suitable storage sites and the development of a comprehensive CO2 transport network are critical for the successful implementation of CCS projects.
  • Technological advancements: Continued research and development are essential to improve the efficiency and cost-effectiveness of CCS technologies. Innovations in capture, transport, and storage techniques can help overcome technical limitations and make CCS more commercially viable.

International Cooperation and CCS

International cooperation is crucial for the successful deployment of CCS technologies in the context of global climate agreements. Collaboration among countries can help address common challenges and share best practices. Several international initiatives and organizations are working towards promoting CCS and facilitating knowledge exchange:

  • The carbon sequestration Leadership Forum (CSLF): The CSLF is a global ministerial-level initiative that aims to promote the development and deployment of CCS technologies. It facilitates information sharing, capacity building, and collaborative research among member countries.
  • The Global CCS Institute: The Global CCS Institute is an international organization that supports the deployment of CCS projects worldwide. It provides technical expertise, policy advice, and knowledge sharing to accelerate the development of CCS technologies.
  • The Clean Energy Ministerial (CEM): The CEM is a global forum that brings together energy ministers from various countries to promote clean energy technologies. CCS is one of the focus areas of the CEM, and member countries collaborate to advance the deployment of CCS technologies.


CCS plays a crucial role in the context of global climate agreements by enabling significant emission reductions and supporting the transition to a low-carbon economy. While CCS offers several benefits, it also faces challenges related to cost, public acceptance, regulatory frameworks, infrastructure requirements, and technological advancements. International cooperation and collaboration are essential to overcome these challenges and promote the deployment of CCS technologies. By harnessing the potential of CCS, countries can make significant progress towards achieving their emission reduction targets and mitigating the impacts of climate change.
