How to Evaluate Your Supply Chain Commitment to Decarbonisation

with NZC Solutions

Evaluating and Strengthening Your Supply Chain’s Decarbonisation Strategy

Evaluating your supply chain’s commitment to decarbonisation in the UK construction sector involves a structured approach that assesses policies, practices, data transparency, and alignment with national and industry-specific sustainability targets. Here’s a practical step-by-step guide tailored for UK construction firms:

Decarbonisation Maturity Assessment & Supplier Prequalification. Categorise suppliers by maturity level to tailor engagement.

Maturity Level	Indicators	Suggested Action
Level 0: Unaware	No carbon data or targets	Basic training, awareness workshops
Level 1: Reactive	Ad-hoc reporting, compliance-driven	Provide guidance, templates
Level 2: Proactive	Carbon tracking, limited targets	Support SBTi alignment
Level 3: Strategic	Net Zero roadmap, LCA use	Strategic partnerships
Level 4: Leadership	Verified carbon-negative processes	Showcase & co-innovate

Procurement Integration. Make carbon a mandatory selection criterion in tenders, not just a “nice to have.”

Quantifying Scope 3 (Supply Chain) Emissions. This is a key pain point. Construction companies are increasingly responsible for Scope 3 emissions – our platform will calculate this for you.

Performance Tracking & KPI Framework. Create a supplier Carbon Performance / Evaluation Scorecard.

Engagement, Capacity Building, & Support. Not all suppliers will be ready, especially SMEs. Constructive engagement is essential.

Contractual Levers & Incentives. Include carbon reporting obligations in contracts, and Mandate digital reporting of carbon data via the NZC platform.

Example: Supplier Carbon Evaluation Template (Excerpt)

Section	Question	Scoring Criteria
GHG Reporting	Do you report Scope 1 & 2 emissions?	Yes = 1; Verified = 2
Scope 3 Coverage	Which Scope 3 categories do you report?	>5 categories = 2
Reduction Targets	Have you set Net Zero targets?	Yes = 1; SBTi validated = 2
EPD Availability	Do you have verified EPDs for your top products?	Yes = 1
Circularity Practices	Do you recover or reuse materials?	Yes = 1; With metrics = 2
Innovation	Any recent low-carbon initiatives?	Yes (describe) = 1–2

How NZC Solutions Can Help

Let us help you on your journey to net zero.

We have the tools that will allow you to assess and align your suppliers to your own Carbon decarbonisation strategy and targets.

NZC Plus: Total Organisational Carbon Management

The NZC Plus platform from NZC Solutions is designed to help UK construction businesses calculate, reduce, and report their full organisational carbon footprint, including Scopes 1, 2, and 3.

It offers real-time carbon tracking using a live UK carbon factor database, allows for third-party verification, and provides actionable insights into emissions hotspots. The tool also integrates with NZC’s Green Marketplace to help source lower-carbon alternatives.

NZC Pro: Project-Level Carbon Tracking

NZC Pro is a carbon management tool designed specifically for UK construction projects. It calculates upfront carbon emissions across project phases (tender, construction, and as-built), aligned with RICS Whole Life Carbon Assessment v2, ISO 14064, and PAS 2080 standards. It offers live data from verified UK carbon databases and automates benchmarking, supplier attribution, and verification-ready reporting.

When combined, NZC Plus and NZC Pro support your supplier decarbonisation journey and provide you with an accurate digital reporting mechanism to evaluate, select and monitor the ongoing performance of your suppliers.

CLIENT SUCCESS:

Winvic Construction

Company Profile

Winvic Construction Ltd is a leading UK main contractor, committed to sustainable construction.

The Challenge

To actively engage, educate and develop their supply chain decarbonisation journey. Selection of suppliers for key Net Zero Carbon projects was based on assessment and their ability to provide real, credible, and reportable data that demonstrates their decarbonisation journey and attributes.

The Solution

Using NZC Plus and NZC Pro as the foundation for a robust, scalable decarbonisation strategy and supplier selection.

Key benefits of both platforms

Live specific UK Construction Carbon Database

Legislative aligned reporting document outputs

Carbon Hotspot Identification & Benchmarking

Supplier & Scope 3 Attribution

3rd Party Verification-Ready Reporting

Key outputs from Decarbonisation Strategy to date

The Majority of their supply chain is on the journey of carbon calculation using NZC Plus and NZC Pro, with a total figure reported to date of 500k + tCO2e.

From the supply chain onboard, around 50% of them have decided to go on the full carbon-neutral journey, using the NZC platform.

Winvic is looking for long-term strategic green supply chain partners to drive forward with Net Zero Carbon innovation and approach towards the delivery of Net Zero Buildings.

Winvic is benefiting from real-time data, providing monitoring and performance criteria of selected suppliers.

We have been seeking a tech partner to support us in educating our Green Supply Chain on accurate carbon reporting for both our operational carbon footprint and our LCA on NZC projects. NZC Solutions is that partner, and with their expertise and the suite of carbon calculator products – NZC Plus and NZC Pro – it has accelerated our mission to decarbonate our operations within the construction industry and assisted us with accurate reporting and reducing ours and our supply chain carbon footprints.
