JSM Group has published its ESG Annual Report 2025, setting out a year of measurable progress across the environmental, social and governance commitments that underpin how the business operates and grows.

Now in its most comprehensive form yet, the report covers JSM’s performance for the year ending 31 December 2025 and reflects work delivered by colleagues across every part of the Group.

“For JSM, ESG is a practical driver of performance, supporting reliable delivery for our clients and helping them build resilient infrastructure,” said Stephen Evans-Howe, Chief Risk & Safety Officer at JSM Group.

Highlights from a year of progress 

On the environmental front, JSM achieved a 99% recycling rate across the Group, with 67,506 tonnes of material reused, recycled or recovered. A Battery Storage Unit trial at Stockport saved 16,892 litres of diesel and cut emissions by 44.9 tCO2e, while a wider trial of the technology delivered a 73% reduction in diesel generator fuel consumption. A trial of HVO fuel demonstrated a 98% reduction in carbon emissions, and solar panels fitted to 27 pieces of plant cut fleet-support callouts by an estimated 80%. All grid-connected facilities now run on 100% renewable electricity.

On the social side, colleagues donated 156 hours of volunteering time and JSM invested £22,000 in local community organisations, supporting projects ranging from the Ealing Beaver Project to Fair Havens Hospice. The Group also launched the JSM Managers University and Leadership Academy, introduced inclusive PPE options, and translated key safety training materials into Romanian to improve accessibility across its workforce.

In governance, JSM maintained a broad portfolio of external accreditations, including its Integrated Management System certifications to ISO 9001, ISO 14001 and ISO 45001, and its ISO/IEC 27001 information security accreditation (now extended to Ireland and Bahrain). JSM also achieved SOC 2 accreditation in 2025.

Building the foundations for net zero 

Looking ahead to 2026, JSM will publish a formal ESG roadmap, work towards setting a Science Based Target, and pursue Great Place to Work accreditation. The Group has also committed to externally verifying its Scope 1, 2 and 3 emissions by 2027, building the foundations for a credible net zero pathway.
