17 December 2025: A specification designed to accelerate the global transition to clean energy and support emissions reduction efforts worldwide has been published by BSI.
Carbon-abated Electricity (PAS 247) establishes the first standardized methodology for monitoring and calculating decarbonized electricity produced by fossil-fuel power plants equipped with carbon capture, transportation and storage (CCS) technology.
The specification is intended to enable organizations and governments to manage low-carbon electricity generation and related supply chains in line with global climate and energy targets, including achieving net zero by 2050. By defining a consistent and verifiable approach to measuring carbon-abated electricity, PAS 247 can help enhance transparency around carbon-reduction performance and support more accurate assessment and reporting of emissions reductions.
The integration of CCS into thermal power plants is increasingly recognized as essential for mitigating carbon dioxide emissions from fossil-fuel combustion and limiting the impacts of climate change. In the UK, the government is seeking to leverage its large carbon storage capacity to scale solutions across heavy-emitting industries.
Seb Van Dort, Director of Sustainability and Energy , BSI, said: “Developed through robust, multi-stakeholder collaboration, this ground-breaking new standard provides organizations and governments with a consistent, transparent and credible framework to support their transition to clean power generation. The global standard is designed to ensure accuracy and reliability of emissions reduction in this emerging area of decarbonization, while strengthening public, regulator and stakeholder confidence in emissions reporting. At BSI, we’re proud to support this critical step in accelerating progress towards a more sustainable world.”
PAS 247 will be relevant to CCS-enabled fossil-fuel power plants and their value chains, governmental authorities, and organizations pursuing carbon-neutral operations, including those in hard-to-abate sectors such as shipping, aviation and heavy industry. The PAS aligns with existing standards and in time is expected to form the basis for third-party certification . Should the PAS be adopted as an ISO standard, it will provide a globally recognized method against which organizations can be certified.
The new standard is designed to provide the following benefits:
Clarity: it defines a clear, consistent method for measuring and verifying carbon-abated electricity from thermal power plants using CCS technologies. It outlines where and how measurements should be taken, helping users navigate technical processes with precision and confidence.
Alignment: it supports national and industry goals by aligning with the UK’s Clean Power by 2030 targets and broader decarbonization strategies. It complements existing environmental standards and can be integrated into certification and labelling schemes.
Credibility: it enhances trust in carbon dioxide removal claims by introducing an independent process that supports third-party verification.
Scalability: it provides a foundation for expanding CCS adoption by de-risking measurement practices and supporting consistent outcomes across an evolving sector.
