Corps Security has been awarded Platinum certification by Neutral Carbon Zone (NCZ), upgrading from Gold status in its third year of working with the independent carbon assessment body. The security services provider recorded a total carbon footprint of 6,184.85 tCO₂e for the 2025 calendar year, representing a 19% reduction from its 2024 figures and a significant step forward in its long-term sustainability journey.
Between 2024 and 2025, Corps’ Scope one direct emissions fell by 35%, driven by the ongoing transition of the company fleet to electric vehicles, which saw company car emissions drop by nearly 39%. Scope two emissions from electricity reduced by more than 94% following the incorporation of renewable energy sources. Scope three indirect emissions, which account for the vast majority of Corps Security’s total footprint, fell by 18%, reflecting reductions across employee commuting and homeworking, purchased goods and services, and well-to-tank emissions.
When measured against revenue, the total carbon footprint per £1 million of turnover fell by over 29% between 2024 and 2025, from 65,919 kgCO₂e to 46,678 kgCO₂e, even as the business grew its revenue by more than 14%.
Achieving Platinum status represents the highest tier of NCZ certification, reflecting Corps Security’s high-detail carbon measurement and continued progress in reducing emissions year-on-year.
NCZ’s carbon footprint reporting recognises organisations that measure their full organisational and operational footprint in line with internationally recognised standards, including the WRI/WBCSD Greenhouse Gas Protocol Corporate Standard and ISO 14064-1:2018. The assessment covers Scope one, two and three emissions.
Sharon McLaren, Quality and Compliance Manager at Corps Security, said: “This Platinum certification from Neutral Carbon Zone reflects the sustained decarbonisation effort from people across our organisation. Progress like this shows that our colleagues are equally committed to our sustainability journey, and our efforts are translating into clear results. We will continue building our sustainable practices aligned with our People, Planet, Purpose philosophy.”
NCZ identified several priorities for the next reporting period. These included further developing staff participation in commuting surveys to strengthen data quality, conducting more in-depth supply chain analysis to identify further efficiencies, and standardising energy and fuel data collection processes across the organisation.
