At Mallon, we believe that meaningful progress starts with honest measurement.
That’s why, for the fifth year running, we’ve calculated and published our full carbon footprint — and once again, we’re sharing the results openly, including the parts of the story that are still a work in progress.
The Headline Numbers
Our total footprint for 2025 was 175,245.367 kgCO2e — a figure that is 88.6% lower than the average business. Broken down further:
- Carbon Intensity per employee stood at 1,460.378 kgCO2e (83.2% lower than the average business)
- Carbon Intensity per £ of revenue stood at 0.03 kgCO2e (75.3% lower than the average business)
A Milestone Year
2025 was a special year for us — we celebrated 30 years in business with a company–wide event for our staff. That celebration added 8,405.4 kgCO2e to our footprint, a one–off cost we’re glad to have incurred marking three decades of Mallon Technology.
Strip that one–off event out, and our underlying emissions for 2025 were actually around 4% lower than our 2021 baseline — continuing the positive trend we’ve built since 2023. We think that’s worth sharing, because it’s the more accurate picture of where our day–to–day operations are heading.
What’s Working
Since we set our 2021 baseline, we’ve made real, measurable progress in the areas most directly within our control. Our Scope 1 and Scope 2 emissions — from company vehicles and the electricity we purchase — have fallen from 13.8% of our total footprint in 2021 to just 1.1% in 2025, a reduction of around 92%.
That didn’t happen by accident. Over the past five years, we’ve:
- Replaced all office lighting with energy–efficient LED bulbs
- Added battery storage to make full use of the solar energy we generate
- Introduced an electric vehicle to our fleet
- Measured and reported on our carbon footprint transparently, every year, since 2021
Where We’re Focusing Next
Like most service–based businesses, the majority of our footprint now sits in what’s known as Scope 3 — the emissions embedded in the products and services we buy, rather than in our own direct operations. It’s a common pattern for companies like ours, and it’s also where we see the greatest opportunity ahead.
Looking forward, we’re focusing on:
- Identifying opportunities to reduce emissions from our supply chain
- Continuing to refine our data collection methods so our reporting gets more accurate every year
- Exploring further ways to reduce emissions from business travel
Aiming Towards Net Zero 2040
Five years into our Net Zero journey the data is able to tell us two things clearly. First, that the changes within our direct control — energy, vehicles, our own building — genuinely work, and we’ve proven that with a 92% reduction. Second, that the next phase of this journey will require looking further afield, to the choices we make about what we buy and who we buy it from.
We’ll keep measuring, keep reporting, and keep sharing the full picture — including the parts still in progress — every year between now and 2040.
