Embedding carbon reduction into public procurement

It is no secret that the carbon management landscape is extremely busy and hard to navigate. There are a wealth of initiatives, groups, guidance, standards, tools and processes to be aware of and to be compliant with. It was a desire to make sense of that busy and complex landscape that resulted in the Carbon Reduction Code. Organisations desperately needed help to prioritise which standards were the most important to align to and why.

With a daunting goal of reaching net zero by 2045 with annual accountability, the Code gives clients and their supply chain a simple framework to examine and test their carbon reduction ambitions and activities. Clients can assess suppliers on a ‘level playing field’ and it is free to sign up.

The Code was started with a CSIC cross industry working group of over 30 professionals from across the sector. NACF members were part of a core group that trialled the initial draft of the Code, along with the Environment Agency and Skanska on behalf of the Skanska Costain STRABG Joint Venture (SCSJV) for HS2. It was fully launched around COP 26 in November 2021.

Members of the NACF sustainability group continue to play an active part in the ongoing management and development of the Code. As Chris Clarke, of SCAPE, and our sustainability co-convenor notes, “Being an active participant enables us to articulate to the wider code team what our clients are looking for and what we value as public sector procurers.”

The promotion of the code has encouraged the sign up of key contractors from our framework supply chains, who now also contribute to the promotion and development of the code with their supply chain business.

Our members use the Carbon Code every day as a KPI to monitor the progress of our contractors on their carbon reduction journey. And by doing so, we also demonstrate our own credentials in leading the decarbonisation of the industry. It gives us a simple way to frame our expectations of industry in our shared carbon reduction journey at prequalification stage of procurement and alongside the Common Assessment Standard.

In Autumn last year, our members joined forces to launch our NACF embodied carbon benchmarking tool. This was about creating a consistent approach across our frameworks, based on the Code principles, and rapidly enabling us to share learning on the construction methods and materials delivering the best results in terms of lowering the embodied carbon footprint of our projects. Mike Raven, Sustainability Manager for YORhub explained that “The priority for the NACF is to form a large and useful source of data to form a benchmark of the primary elements of embodied carbon via the Embodied Carbon Benchmarking tool.”

The code now features in the UK Construction Playbook, the UKGBC Roadmap and is hosted by the University of Cambridge and supported by the Construction Leadership Council’s Co2nstruct Zero initiative. The Supply Chain Sustainability School has developed a ‘Carbon Reduction Code for the Built Environment: Resource Mapping Table’ which is available from the School’s Resource Library.

It includes three levels of commitment, Pledger, Signatory and Champion and aligns to initiatives such as PAS 2080, BECD and SBTi.

Natasha Clark, Programme & Business Change Manager, Environment Agency told us: “We chose to make a commitment to the Carbon Reduction Code because it brings together requirements of UK net zero legislation, procurement requirements, international standards and industry best practice guidance in a structured way. This then makes it relatively easy for us to benchmark and understand our maturity in the journey toward net zero.

“As an infrastructure client, driving consistency across the sector is essential and the Code helps us to align requirements/standards and create necessary client pull to accelerate change.

“Becoming part of the Carbon Code Champions Group has offered the chance for peer-to-peer learning and the safe space to benchmark our approach in addressing the climate emergency. It also shows we are committed to working with other infrastructure clients and supply chains to support them on their own decarbonisation journey.”
