Carbon Management

Carbon Management Who we are

Our Commitment

Keltbray is a UK-leading specialist in construction engineering and a major civil services group. We are at the forefront of delivering sustainable, innovative, and high-performance solutions.

Our purpose is to redefine the way sustainable development is delivered.

Climate change is one of the most urgent sustainability challenges of our time. Carbon management underpins Keltbray’s core purpose to redefine the way sustainable development is delivered.

Based on our collective and multidisciplinary experience, we focus our integrated services on solving customers’ engineering challenges in a rapidly changing world.

Working in partnership with our stakeholders, we are actively contributing to economic growth, social advancement, and environmental protection.

Keltbray has calculated and verified our Scope 1, 2 and 3 emissions through the Science Based Targets Initiative and outlined our strategy for carbon reduction in the Carbon Reduction Plan. Though not an asset owner, we recognise our role in driving carbon reduction. We are committed to being a proactive contractor, collaborating with stakeholders to: – Understand our client’s ambitions, beliefs and drivers which lie behind project scope requirements – Align with project carbon goals and sustainability strategies.

– Promote continual improvement through workshops, lessons learned and transparent reporting

– Identify and challenge clients to adopt practical reduction measures, where use of lowcarbon materials and efficient construction methods are implemented considering programme, practicality and cost – Encourage and support suppliers to deliver lower-carbon solutions

PAS 2080 Certified Keltbray has held PAS 2080 certification for over two years, demonstrating our commitment to consistent, transparent carbon management. Our audit confirmed: – Leadership & Governance: decarbonisation embedded in policy, strategy and culture, supported by senior leadership.

– Carbon Management Process: clear procedures for identifying reduction opportunities during pre-construction and tracking emissions.

– Competence & Training: ongoing investment in training and incentives for decarbonisation.

– Continual Improvement: regular reviews, sharing of case studies, and influencing the wider industry through collaborative research.

This accreditation confirms carbon management is central to our operations, independently verified against global best practice.

Whole Life Carbon Assessments We work collaboratively with clients in delivering WLCAs across A1–A5 stages, offering: – Transparent datasets aligned with baselines and targets – Data from Environmental Product Declarations (EPDs), government carbon factors and supplier-specific sources – Integration of our in-house reporting tool with our procurement system for rapid access to as-built quantities, supporting client Stage 5 WLCAs – A curated library of Environmental Product Declarations

Identifying Lower-Carbon Alternatives Keltbray goes above and beyond compliance to reduce embodied carbon by: – Reviewing construction methods to assess programme and method impacts – Trialling and adopting lowercarbon materials (e.g. Calcined clay, EFC)

– Recommending designled alternatives such as optimised concrete mixes and piling strategies – Promoting early engagement to embed reductions at planning and procurement stages

CARBON FORECASTING – PROJECT HIGHLIGHTS Pegasus House – Scope: temporary works, bulk dig, piling, substructure and core superstructure elements – Baseline, monitor, and report across A1–A5 lifecycle stages – Quarterly updates to the client, with monthly tracking against a 384 kgCO₂e/m2GIA target for the package target – Forecasting models to predict future performance

Sector-Specific Tools – FPS Carbon Active use of the FPS Carbon Calculator to evaluate piling methodologies.

– Quantifies embodied carbon impacts to provide clear, evidence-based comparisons – Supports client decision-making with robust carbon data – Identifies opportunities for lower-carbon alternatives at design stage – Embeds carbon management and reduction strategies early in project delivery

10 King William Street, 2 Aldermanbury Square & 50 Fenchurch Street – Forecasting and reporting across all phases, aligned with client baselines – Provided integrated sustainability data for accurate project-level reporting – Collaborated with design teams to implement lower-carbon solutions (e.g. steel decking) and drive reductions through delivery stages Lower-Carbon Materials Keltbray has a proven track record in adopting low-carbon materials: – At Canada Water, Keltbray developed a testing specification with the engineer, for the use of EFC in permanent piles – First use of London Concrete’s Calcined clay mix in temporary works, with trials underway for permanent applications – EFC used in constructing hardstanding at our Plaistow Wharf waste facility
