Landlords & Investors
Net Zero Carbon Reports
Asset and portfolio-level NZC pathway reports aligned with the UK Net Zero Carbon Building Standard, CRREM benchmarks, and UKGBC guidance — giving landlords, funds, and investors a credible, costed route to net zero.
What it is
A Net Zero Carbon Report is the core deliverable for a commercial building or portfolio seeking to understand and close the gap to net zero carbon. It combines operational energy assessment, carbon benchmarking, CRREM pathway analysis, and a costed carbon reduction roadmap — producing a single, investor-grade document that evidences where a building is today and what is required to achieve NZC alignment.
We produce NZC Reports aligned to the UK Net Zero Carbon Building Standard v1 (March 2026) — the definitive UK framework for net zero buildings, co-developed by RICS, CIBSE, RIBA, UKGBC, LETI, BRE, BBP, and IStructE. Our reports are suitable for use by landlords, asset managers, property funds, REITs, and institutional investors as the technical foundation for NZC claims, ESG disclosures, and asset management decisions.
When you need it
- You own or manage a UK commercial building or portfolio and want to understand its position against NZCBS v1 operational energy and carbon limits.
- Your fund or investment strategy requires NZC-aligned assets and you need a credible technical assessment to underpin that commitment.
- A lender, investor, or Green Loan framework is asking for evidence that your assets are on a credible net zero pathway.
- You are preparing a GRESB submission and need asset-level NZC pathway evidence for the performance component.
- You are acquiring an asset and want an NZC due diligence report to understand stranding risk, capex requirements, and alignment timeline.
- You want to make a formal NZCBS claim — "Net Zero Carbon Aligned Building" or "NZC Aligned Building (plus offsets)" — and need the technical assessment to support it.
Our approach
- 1
Data collection and baseline
We collect twelve months of energy consumption data (electricity, gas, district heat, on-site renewables) and verify metered data against available EPCs, DECs, and half-hourly data where accessible. We establish the operational energy intensity baseline in kWh/m²/yr and the associated carbon intensity in kgCO₂e/m²/yr.
- 2
NZCBS gap analysis
We assess the building's operational energy intensity against the applicable NZCBS v1 limit for its building type and use (from NZCBS Annex A tables). We identify whether the building is currently within the limit, the magnitude of any gap, and which energy end-uses are driving excess consumption.
- 3
CRREM pathway modelling
We run the building through the CRREM V2 pathway tool to establish its current carbon intensity position against the 1.5°C and 2°C decarbonisation pathways, and identify the Misalignment Year — the point at which the building's carbon intensity exceeds the CRREM pathway if no action is taken.
- 4
Carbon reduction measures
We identify the technically feasible carbon reduction measures available to the building — building fabric improvements, heating system decarbonisation, renewable energy installation, smart controls — and model the carbon and energy impact of each.
- 5
Financial appraisal
We apply a 15-year NPV appraisal to each measure using HMT Green Book methodology: 3.5% discount rate, BEIS/DESNZ central energy price escalation, and UK ETS carbon price. This gives the landlord a clear investment case for each measure, not just a list of recommendations.
- 6
NZC pathway report
We produce the full report: baseline, gap analysis, CRREM outputs, prioritised measures, financial appraisal, and a recommended pathway to NZCBS alignment — with a clear statement of whether the building can make the "targeting alignment" claim under NZCBS §7.5.
What you receive
NZC pathway report
A complete asset-level report covering operational energy baseline, NZCBS gap analysis, CRREM pathway, carbon reduction measures, and recommended NZC alignment pathway — suitable for board, investor, and lender audiences.
CRREM outputs
Pathway charts showing current carbon intensity versus the 1.5°C pathway, the Misalignment Year, and the carbon intensity trajectory under the recommended measures.
Financial appraisal
A 15-year NPV table for each recommended measure — annual energy saving (kWh), annual cost saving (£), carbon saving (tCO₂e), simple payback, and discounted NPV.
NZCBS proforma data
Completion of the relevant sections of the NZCBS v1 submission proforma (rev01 April 2026) for the building, ready for verification submission.
Executive summary
A two-page investor-facing summary of the building's NZC position, recommended pathway, and key metrics — formatted for inclusion in ESG reports and investor disclosures.
