Jons Civil Engineering Company Ltd has reduced generator-related emissions by up to 90% after switching from fossil diesel to ISCC-certified hydrotreated vegetable oil (HVO) supplied by Tria Energy.
The move forms part of the company’s wider decarbonisation programme, targeting emissions from energy-intensive site operations while maintaining the reliability required for temporary power.
Because HVO is a drop-in fuel, the transition required no changes to existing generators or fuel infrastructure, allowing immediate implementation across active projects.
Kara Lacey, Sustainability Manager at Jons Civil, said the solution delivered both environmental and operational confidence: “Reliable temporary power is non-negotiable for our projects, but so is reducing our environmental impact. Introducing HVO enables us to deliver immediate carbon reductions without compromising performance.”
A practical step
The company describes the introduction of HVO as a practical step that supports wider sustainability goals. The first company in Ireland to achieve Level 4 on the Carbon Ladder in Ireland & the UK, Jons Civil Engineering is leading the way on impactful sustainability solutions.
The case highlights the growing appeal of HVO for contractors seeking practical, near-term emissions reductions without the capital investment or operational change associated with alternative technologies.
Operational benefits reported include cleaner combustion, reduced exhaust odour and verified emissions savings supported by ISCC-certified supply chains.
Tria Energy CEO Patrick Kirby said the project demonstrates how quickly generator decarbonisation can be achieved in practice: “This shows how HVO can be implemented quickly, safely and at scale while maintaining reliable site power.”
As infrastructure and construction firms face increasing pressure to demonstrate measurable emissions reductions, HVO is emerging as a viable transitional solution – particularly in applications where electrification remains challenging.
