In addition to the Pledger and Signatory commitments, Client Champions commit to:

2.5 Together with our supply chain, we will develop outcome-based specifications and commercial arrangements, where possible, ensuring outputs are not constrained to current thinking but encourage low carbon innovations. We commit to ongoing support and engagement with the supply chain to accelerate achievement of the desired outcomes.

2.6 We have established consistent measurement of carbon on projects and in our organisation, and share these on industry databases (e.g BECD and NACF Embodied Carbon Database) for the purposes of benchmarking and performance improvement. To achieve this, we commit to share our carbon data openly, through a national carbon integrator (where available) and through working with industry.

2.7 We commit to implementing approaches that improve our capability to measure and reduce embodied and operational carbon:

• in the design and construction phase;

• during the life of existing assets; and

• during decommissioning and end-of-life.

2.8 We will align our capital and operational investment plans with the national net zero carbon obligation, including retrofitting decarbonisation to our existing asset operations and their use. We will use early-stage optioneering to prioritise no-build and low-build solutions, which optimise existing assets, systems and processes, before new build is considered. We will encourage multi-sector, system of systems approach, to seek integrated sustainable solutions and achieve a balanced outcome for the natural and built environment.

2.9 As clients, we will work together (with our peers, umbrella industry bodies and our supply chains) to proactively share best practice around our methodologies for carbon measurement and management. By also understanding where we have ‘common asset types and activities’ we will ensure we all measure and report on the carbon in these assets/activities consistently.

2.10 We will share knowledge and information on the benefits of circular economy principles and nature-based solutions for carbon sequestration and increased resilience instead of ‘hard engineering’ interventions.

2.11 We will share our decarbonisation roadmaps both for new and existing assets, with the aim of contributing towards the national net zero carbon transition.

Alternatively, Supply Chain Champions commit to:

3.6 (Contractors) We will proactively support our supply chain to adopt carbon measurement and carbon reduction, and will require them to report on carbon.

3.7 We are committed to the collation and sharing of carbon reduction data across the industry. We will contribute data, for example, into a publicly available carbon measurement database (e.g BECD and NACF Embodied Carbon Database) or provide carbon data to clients who will enter the data to such a database for the purposes of benchmarking and performance improvement.

3.8 (Consultants) We will work with clients to consider the carbon hierarchy options before a new build is committed to. Where possible, we will integrate nature-based solutions and circular economy principles in the design development and delivery of projects.

3.9 We will proactively share our own best practice across the supply chain and our learning from adopting others best practice where possible, for example with reference to the Supply Chain Sustainability School, and annual reports of the Infrastructure Carbon Review.

3.10 We commit to implement approaches that improve our capability to measure and reduce embodied and operational carbon in the design and construction phase, including reducing the carbon footprint of materials, reducing waste and decarbonizing construction operations.

Compliance to the CRCBE is reviewed annually. In the initial application and at the point of review, compliant organisations are required to provide evidence of a carbon reduction plan (or the creation of one in the first year) targetting net zero by 2045 and annually published progress reports.
