Delivering Industry‑Leading Carbon Reporting to Meet Escalating Client Demands
Challenge / Problem
Major clients were increasingly requiring suppliers to provide comprehensive, auditable Greenhouse Gas (GHG) emissions data as part of PQQ and tender submissions.
This pressure was escalating rapidly. Clients were no longer satisfied with Scope 1 and Scope 2 data alone, they also demanded detailed reporting across all 15 Scope 3 sub‑categories, often accompanied by multi‑year forward projections covering the full contract duration.
The company urgently needed a robust, defendable methodology for capturing, calculating, and forecasting its emissions, or risk losing competitive opportunities.
Client Overview
The client is a privately owned, £75 million turnover company specialising in the installation, modernisation, servicing, and repair of complex, safety‑critical equipment. Headquartered in London, the organisation operates through multiple regional offices across the UK.
They had a mature, integrated management system certified to ISO 9001, ISO 14001, ISO 45001 and ISO 50001, and had extended the same system to encompass key regulatory requirements, enabling both UKCA and CE marking of products.
This foundation gave them a strong starting point, but GHG reporting at the scale now required demanded a far more detailed approach.
Approach and Solution
Given the company’s size, compliance with ESOS (Energy Savings and Opportunity Scheme) and SECR (Streamlined Energy and Carbon Reporting) was already well‑established. As a result, Scope 1 and Scope 2 data was readily available and clearly understood:
- Scope 1: Energy combusted — primarily the vehicle fleet
- Scope 2: Energy purchased — mainly electricity for heating and lighting
- Scope 3, however, required a more complex and exhaustive analysis mirroring the GHG categorisation of:
- Upstream categories: Purchased Goods & Services, Capital Goods, Upstream Transportation & Distribution, Waste, Business Travel, Employee Commuting
- Downstream categories: Transportation & Distribution, Processing of Sold Products, Use of Sold Products, End‑of‑Life Treatment of Sold Products
The critical first step was ensuring senior leadership were fully bought in. Presentations were delivered to directors and managers explaining:
- Why clients were demanding this level of data
- The calculation processes involved
- The support required from each department
Once commitment was secured, structured meetings were held, and data collection began across the Group.
The next step was to apply a pragmatic, defendable methodology. Data from the company’s accounts system was extracted, sorted by business unit, supplier and product type. A Pareto (80/20) approach was then used to identify the categories driving the majority of emissions and costs. These were reorganised into reporting groups aligned with the UK Government’s published emissions conversion factors.
Where accurate data was not yet available, logical, justified assumptions were made, with a plan to refine them as improved information became accessible.
This approach allowed the company to establish a credible, evidence‑based GHG reporting framework without delaying tenders or overwhelming internal teams.
Outcome and Impact
The company became the first in its sector to have its GHG emissions independently verified by an approved verification agency in accordance with ISO 14064.
This achievement enabled the organisation to:
- Present fully verified, audit‑ready emissions data in tender submissions
- Demonstrate a level of transparency and maturity far beyond competitors
- Strengthen relationships with major clients by exceeding their reporting expectations
- Apply commercial pressure on competitors who could not match this level of verification
The result was a clear competitive advantage, positioning the company as a sector leader in carbon accountability and future‑ready sustainability reporting.
