Carbon Funding — Service 01
Construction CO₂ Offsetting & Net Zero Buildings
Portfolio CO₂ monitoring, net zero building planning, and verified carbon offsetting for new-build and retrofit developers — turning construction-phase and operational carbon obligations into a structured, auditable net zero programme.
What this service covers
Every building has a carbon story — we help you tell it, reduce it, and offset the rest
Buildings are responsible for approximately 40% of the UK's total carbon emissions — split between the carbon emitted during construction (embodied carbon) and the carbon produced through energy use once occupied (operational carbon). Both need to be measured, reduced, and — where reduction is not yet possible — offset through verified voluntary carbon markets.
RetrofitScore manages the full construction and operational carbon lifecycle — from initial embodied carbon assessment and net zero planning through to ongoing portfolio monitoring, voluntary market access, and verified carbon retirement.

How we deliver
From carbon assessment to verified net zero — a complete managed programme
Every Construction CO₂ and Net Zero Buildings engagement follows a structured process — ensuring carbon is measured correctly, reduced as far as possible, and any residual emissions are offset through verified, credible market mechanisms.
Embodied carbon assessment — RICS & PAS 2080:2023
We quantify the embodied carbon of your construction project using RICS Whole Life Carbon Assessment methodology and PAS 2080:2023 — covering substructure, superstructure, finishes, services, and external works. Bills of quantities, material specifications, and transport data are analysed to produce a verified carbon footprint across RICS life cycle stages A1–A5, B1–B7, and C1–C4.
Operational carbon baseline & monitoring
We establish a verified operational carbon baseline using actual energy consumption data — Scope 1 (gas, fuel), Scope 2 (purchased electricity), and relevant Scope 3 sources. Year-on-year operational carbon is tracked against the baseline, with performance measured against RIBA 2030 Climate Challenge targets and UKGBC net zero operational benchmarks.
Net zero building roadmap & reduction plan
We develop a structured net zero roadmap — sequencing embodied carbon reduction measures (low-carbon materials, MMC, structural optimisation) alongside operational improvements (fabric, renewables, low-carbon heating). Reduction targets are set against science-based pathways, with a costed implementation programme for each phase of delivery.
Portfolio CO₂ term planning & carbon finance
For developers and investors managing multiple assets, we produce a portfolio-level CO₂ term plan — prioritising properties by carbon impact and sequencing improvements over a defined plan period. Carbon savings generated by completed improvements can be forward-sold to fund subsequent phases of delivery, creating a self-financing carbon programme.
Verified carbon credit brokering & retirement
For residual emissions that cannot yet be eliminated, we broker access to verified carbon credits across Gold Standard, Verra VCS, UK Peatland Code, and Woodland Carbon Code registries. Credits are selected to match your sector, geography, and reporting requirements — then retired on your behalf with full chain-of-custody documentation, serial numbers, and retirement certificates.
Reporting, disclosure & planning condition support
We produce net zero carbon reporting for planning conditions, investor disclosure (TCFD, CDP, GRESB), ESG reporting frameworks, and voluntary sustainability accreditations. Reports include verified carbon footprints, reduction trajectories, offset retirement records, and narrative compliance statements — ready for submission, publication, and audit.
Carbon Type 01
Embodied Carbon
The CO₂ emitted during the manufacture, transport, and installation of construction materials — and at end of life. Responsible for around 11% of global emissions. We quantify embodied carbon to RICS and PAS 2080:2023 standards across the full building lifecycle.
Carbon Type 02
Operational Carbon
The CO₂ produced by a building's energy use once occupied — heating, cooling, lighting, and plug loads. We monitor operational carbon year-on-year against a verified baseline, tracking performance against net zero targets and RIBA 2030 benchmarks.
Carbon Type 03
Residual Carbon Offsetting
Where emissions cannot yet be eliminated, we broker access to verified voluntary carbon credits — Gold Standard, Verra VCS, UK Peatland, and Woodland Carbon Code — retiring credits on your behalf with full certificates, serial numbers, and audit documentation.
What's included
A complete construction carbon service
Every element of the construction and operational carbon lifecycle — under one managed programme, with one accountable team.
Embodied Carbon Assessment
RICS WLCA and PAS 2080:2023 compliant embodied carbon quantification — covering all life cycle stages A1 to C4 across materials, transport, construction, and end of life.
Operational Carbon Monitoring
Year-on-year operational carbon tracking against RIBA 2030 and UKGBC benchmarks — Scope 1 and 2 data collected, verified, and reported across your portfolio.
Net Zero Building Roadmap
Structured net zero plans sequencing embodied and operational reduction measures — with science-based targets, costed delivery programmes, and milestone reporting.
Portfolio CO₂ Term Planning
Multi-asset carbon term plans prioritising properties by impact and sequencing improvements over a defined period — with forward carbon sales to fund delivery.
Verified Offset Brokering
Gold Standard, Verra VCS, UK Peatland, and Woodland Carbon Code credits — selected, brokered, and retired on your behalf with full chain-of-custody documentation.
Planning & Investor Reporting
Verified net zero carbon reports for planning conditions, TCFD, CDP, GRESB, and ESG disclosure — ready for submission, publication, and independent audit.
Why RetrofitScore
Construction carbon expertise grounded in real delivery
We don't just produce carbon reports — we deliver the retrofit and decarbonisation programmes that generate the savings. That means every carbon figure we report comes from a verified, real-world measure, not a desktop estimate.
