Biomass and CCS – Guidance for accounting for negative emissions

Market Models for CCUS/CDR – A Global Screening

• 10 September 2025
• Industry Insights
• Policy & Regulation

This report provides a key pillar to interested parties including policy makers, regulators, and the technical carbon capture, utilisation and storage (CCUS) / carbon dioxide removal (CDR) community on potential successful market strategies, including their pros and cons and their suitability for dierent economic and political realities, which may lead to the fast development of an efficient, safe, and accepted CCUS/CDR market sector.

CO2 Flow Metering Technologies

• 4 September 2025
• Policy & Regulation
• Transport

The main objective of this study is to raise awareness of the relevance, state of the art, challenges and opportunities of flow metering for carbon capture, utilisation and storage (CCUS). Flow metering of CO2 streams will be critical in supporting trade, protecting consumers, ensuring confidence, facilitating taxation, and meeting CO2 reduction goals and treaty obligations.

Managing the transition of depleted oil and gas fields to CO₂ storage

• 12 August 2024
• Policy & Regulation
• Storage

This work provides a careful and thorough exploration of the major issues involved in the transfer of use of a field from hydrocarbon extraction to CO₂ storage, to identify both the pros and cons of such a transition.

International Standards and Testing for Novel Carbonaceous Building Materials

• 1 December 2023
• Policy & Regulation
• Utilisation

Over 4 billion tonnes of cement are produced each year, equating to approximately 8% of global anthropogenic CO₂ emissions, and this industry will continue to grow with the expansion of the built environment at a time that emissions need to be reduced. The utilisation or reduction of CO₂ within cement, concrete and building materials could be a valuable way to contribute to emissions reductions in the sector , but there are several barriers, including the current state of standards, regulations and policies. This study will provide useful information for the technical and research community, the CCUS industry, the construction industry, and policymakers, providing an unbiased and non-prescriptive evaluation of international standards and testing relevant to novel carbonaceous building materials to address some of those barriers. The market potential for CO₂ utilisation processes in the construction industry is also investigated, and the methods for certifying and measuring embodied carbon content of carbonated building materials is evaluated and the challenges therein.

Integrating CCS in international cooperation and carbon markets under Article 6 of the Paris Agreement

• 18 January 2023
• Policy & Regulation

This work assesses the status of and outlooks for international cooperation under Article 6 of the Paris Agreement and considers how approaches could support the deployment of carbon capture and storage (CCS). It provides an up-to-date look at the Article 6 rules, the types of markets and mechanisms that could evolve, and the units that could be traded. It then considers how Article 6 could apply to CCS through linked emissions trading systems, crediting systems and alternative approaches.

Applying ISO Standards to Geologic Storage and EOR Projects

• 1 September 2022
• Policy & Regulation
• Storage

The work aims to summarise and synthesise the two ISO Standards relevant to the geological storage of CO₂: – ISO 27914:2017 (‘Carbon dioxide capture, transportation and geological storage – Geological storage’) and ISO 27916:2019 (‘Carbon dioxide capture, transportation and geological storage – Carbon dioxide storage using enhanced oil recovery (CO₂-EOR)’) – to provide a high-level understanding of the content into an easily digestible format. By comparison with international regulatory frameworks, and providing case studies of how applicable the standards are to real CO₂ storage projects, the study provides a comprehensive overview and concludes on the usefulness of the documents in supporting the implementation of CCUS projects. For the purposes of this overview, the standards will hereafter be referred to as ISO 27914 and ISO 27916

CCUS in national GHG inventories

• 28 June 2021
• Policy & Regulation

This report builds upon previous IEAGHG studies on the topic of carbon capture and utilisation (CCU) in order to assess the potential of a portfolio of CCU technologies to contribute towards Japan’s climate change mitigation goals in 2030 and 2050.
