Publication Overview

The overall objective of this assessment was to improve the availability and accessibility of information regarding the relevance of CCS in contributing to the achievement of the Sustainable Development Goals. The primary objective was achieved through the completion of three key goals:

  1. Collation of existing information on impacts of CCS on specific targets of the 17 SDGs, using the rating, scoring and information assessment as per IPCC’s SR1.5,
  2. Articulation of specific gaps in information, and
Proposal of a path forward by providing a prioritised lists of gap closures.There is a growing body of literature orientated towards converting climate action into policies directed towards implementation of SDGs. There is also a trend of material becoming available examining the interaction of technologies and sectors against SDGs. CCS remains a complex technological solution to climate change, and public understanding of the technology remains low. This study can help to substantiate the wider value of CCS, but it can also highlight points of attention/action on potentially negative interactions with specific SDGs.

Publication Summary

  • This study has mapped carbon capture and storage (CCS) against a select number of the 17 sustainable development goals that have a direct interaction for both the power and industrial sectors.
  • CCS has a number of positive interactions with the SDGs:
         o The considerable potential for CCS to immediately decarbonize both the power and industrial sector means that the deployment of CCS is considered indivisible with actions needed to combat climate change and its impacts (SDG13).
         o CCS plays an enabling role in the provision of reliable, sustainable and modern energy and can support the decarbonisation of industry both through direct emissions reductions but also indirectly through the supply of low carbon power (SDG7).
         o CCS can promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all and contribute to a decoupling of economic growth from environmental degradation, through the reduction of CO2 emissions (SDG8).
         o CCS can also enable sustainable infrastructure developments as well as inclusive and sustainable industrialization, provide a boost to innovation systems, (SDG9), and reduce the carbon footprint of cities to make them more sustainable (SDG11).
         o Through the reduction of CO2 in the atmosphere, CCS can enable the stabilisation of ocean acidification (a key target of SDG14, i.e. SDG14.3).
  • CCS can also have a number of negative interactions with the SDGs:
  • Lifecycle emissions may result in counteracting or constraining interactions with a number of SDGs (3, 6 and 15).
  • In a demand-driven scenario, the energy penalty of CCS means that it can be seen as a constraint on meeting energy efficiency targets (SDG7) but this is only if the assumption that the additional electricity production due to the energy penalty will be supplied by fossil fuels with CCS. In a modern electricity system based on economic generation dispatch (merit order) this may not be the case (see sections on Approach and Limitations for more context).
  • Although CCS obtained a variety of scores across the SDG targets in the assessment, for none of the mapped SGDs CCS was seen as ‘cancelling’, i.e. making it impossible to reach the related SDG and/or sub target.
  • A number of limitations apply when using the results of this study for policy development:
         o Availability and comparability of data.
         o Definition of the counterfactual will impact on the results (e.g. demand-driven vs capacity-driven scenario, in the latter most negative impacts of CCS, i.e. the ones related to the energy penalty and the related fuel consumption, will not materialise).
         o Construction and use of all low-emission technologies will have various environmental, economic and social impacts, i.e. evaluation of trade-offs in isolation will likely have limited value for policy development and selection of pathways.
  • Several knowledge gaps were identified and recommendations for further work include:
         o Additional lifecycle assessments (LCAs) of 2nd generation CCS technologies and CCS in industry (especially in terms of water and energy efficiency gains).
         o More studies on the macroeconomic impact of CCS in different regions.
         o Research on the employment aspects of CCS compared to other low-emission technologies.
         o Investigation of the role of certain CCS technologies for carbon dioxide removal (CDR), i.e. bioenergy with CCS (BECCS) and direct air capture with CCS (DACS)

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.

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

Exporting CO2 for Offshore Storage – The London Protocol’s Export Amendment and Associated Guidelines and Guidance

  • 12 April 2021
  • Policy & Regulation
  • Storage

The London Convention and London Protocol are the global treaties that protect the marine environment from pollution caused by the dumping of wastes. Since 2006, the London Protocol has provided a basis in international environmental law to allow carbon dioxide (CO2) storage beneath the seabed when it is safe to do so, and to regulate the injection of CO2 into sub-seabed geological formations for permanent isolation. However, Article 6 of the London Protocol prohibits the export of waste or other matter for dumping in the marine environment. Therefore in 2019, Contracting Parties to the London Protocol adopted a resolution to allow provisional application of the 2009 amendment to Article 6 of the Protocol to allow export of CO2 for storage in sub-seabed geological formations in advance of its ratification, which was progressing slowly.

Integrated GHG accounting guidelines for CCUS

  • 1 November 2019
  • Policy & Regulation

This report sets out accounting guidelines for measuring greenhouse gas (GHG) emissions and emissions reduction effects arising from technologies involving carbon dioxide capture, utilisation and geological storage (CCUS).The guidelines apply a project- and product-based approach to measure GHG emission reduction effects, based on comparing the emissions for a CCUS activity with the emissions from a comparable activity delivering the same product or service.A modular approach is applied. Firstly, users calculate the GHG effects arising from the capture (and transport) of CO2 based on the avoided emissions from providing the same service or product as output from the CO2 source facility, but without CO2 capture.The resulting estimate of GHG effects from CO2 capture is carried forward to the utilisation or storage step. In this subsequent step, the GHG emissions from providing the same service without using captured CO2 is estimated and compared to the GHG emissions of providing the service using captured CO2. This provides an overall estimate of the cradle-to-gate GHG effect of CCUS activities.Additional guidance is provided on cradle-to-grave assessment, although this is not the primary focus of these guidelines – the Guidelines focus on annualised GHG emissions accounting cycles rather than whole life emissions analysis.

GHG Accounting for CCU Technologies – Characterising CCU technologies, policy support, regulation and emissions accounting

  • 1 March 2018
  • Policy & Regulation
  • Utilisation

Over recent years, interest in CO2 capture and utilisation (CCU) from policy-makers, industry and academics has increased dramatically, although uncertainty remains regarding the technology’s true potential to contribute towards wider greenhouse gas (GHG) emissions reduction goals. A range of views have been expressed in these contexts, but on the whole it remains largely speculative and unproven. Consequently, it is difficult to provide firm opinions on whether CCU technologies can make a meaningful and lasting contribution to tackling climate change. This report provides an assessment of the range of views presented by various stakeholders, and attempts to establish an empirical evidence base upon which to qualify the views and opinions expressed.Additionally, the key way to gain a clearer understanding of the potential for CCU technologies to reduce GHG emissions is to assess the overall energy and carbon balances for different CCU processes, and to take a view on how and whether these could make a contribution to GHG emission reductions. In other words, as noted by the Intergovernmental Panel on Climate Change (IPCC) in its 2005 Special Report on Carbon Dioxide Capture and Storage (SRCCS) ‘further study of the net energy and CO2 balance of industrial processes that use the captured CO2 could help to establish a more complete picture of the potential of this option’. Such detailed studies have, at best, only partially been carried out and are heavily reliant on the assumptions made in the analysis. Thus, IEAGHG has commissioned Carbon Counts (UK) Ltd to characterise CCU technologies, as well as their policy support, regulation and emissions accounting.

Clean steel an environmental and technoeconomic outlook of a disruptive technology

  • 1 March 2024
  • Capture
  • Costs of CCUS

This study primarily presents a comparative analysis of steelmaking pathways to cost-effectively decarbonise a steel mill, taking a life-cycle perspective on associated environmental impacts. The roll-out of clean steel technologies is envisioned to have a significant implication for support infrastructure. Therefore, a secondary objective of the study is to gain insights into the primary energy and infrastructure implications associated with large-scale deployment of different steel decarbonisation pathways. Clean steel production will likely be more expensive than steel produced today; this poses additional economic strains on steel producers and consumers. Consequently, a third objective is to estimate the price premium that clean steel could command in existing and future markets. Further, this study formulates recommendations for key stakeholders to support the sector and outlines recommendations for further work.
