UK ad agencies emit over 84,000 tonnes of operational CO₂ a year. Most production sustainability claims don't show the working. Here's ours: where Tungsten's emissions actually come from, where the structural advantages live, and where they don't.
# Ad Net Zero is a maths problem. Here's our working.
UK advertising agencies emit more than 84,000 tonnes of operational CO₂ a year. 42% of that comes from energy. 58% comes from travel. The Ad Net Zero target for the UK industry is real net zero by the end of 2030. 61% of Ad Net Zero supporters opted into the top "Accelerator" tier.
That's the maths. It's been public for a while.
What's harder to find is the working.
Walk through any production company's "sustainability" page and you'll see the same three claims, repeated almost word for word. We're committed to greener production. We use AdGreen. We offset our shoots. The certifications are real. The intent is genuine. The maths behind the claim is almost never published, which means agency procurement teams trying to compare production routes on carbon impact are working from vibes.
We think that's the bit worth fixing first.
This piece is our attempt to put the working on the table. Where Tungsten's emissions actually come from. Where the structural advantages live. Where they don't. What we're doing in the bits that are still hard.
Production carbon falls into four categories, almost always in this order of impact:
Travel and energy do most of the damage. Almost everything else is rounding error by comparison.
We're a Leeds production studio with a London office. That's a sentence about geography and it's also a sentence about carbon.
Crew. When we shoot in our Armley studio, the crew lives in Leeds, Bradford, Wakefield, Manchester. Almost nobody is on a train from London. Across a four-day shoot with a forty-strong crew, that single fact is the largest carbon line on the call sheet, and it's already gone before we start.
Energy. The studio runs on renewables. That removes most of the 42% energy bucket from the working before we power up a single light. We're publishing the kilowatt-hour figures with our next quarterly update, alongside the supplier certificate, so it's checkable rather than rhetorical.
Virtual production. A VP shoot replaces location travel almost entirely. Eight markets shot in one Leeds room is a different carbon footprint to eight markets shot on location. CUBE Studio's 2025 reporting points to agencies that have won global campaigns specifically because VP let them hit the client's sustainability KPIs. We see the same pattern in our own briefs.
The prep kitchen. Food shoots produce real food. We rehome what's edible through local networks rather than skipping it. It's not a forty-tonne saving. It's the right thing to do and it's measurable.
That's the structural side. What it isn't is a guarantee. The structure helps the average shoot. It doesn't replace per-project measurement, which is what AdGreen exists for.
Honesty buys credibility. Here are the bits where the carbon savings stop:
International talent. Some campaigns need a face that flies in. The renewables tariff in our studio doesn't undo the flight. The honest answer is to plan for it, log it, and not pretend it didn't happen.
Single-asset shoots. A single TVC shot conventionally on a Leeds location with a local crew can be lower-carbon than the same TVC shot on VP, because LED volumes draw real power. VP becomes structurally cleaner when one shoot day produces multi-market, multi-format assets. Single-output shoot days are where it stops compounding. We tell agencies that early. It loses us the brief sometimes. We think that's correct.
Post. Render farms and grading suites run on whatever the building runs on. We're on a renewable supply. Our post partners aren't always. We can only represent our own numbers.
Each of these gets logged on the project carbon report. We don't bury them.
Offsets sit at the end of a sustainability strategy. The first 95% is reduction: energy source, travel, production method, crew geography. Offsetting what you couldn't reduce is the right last step. Offsetting first and reducing as an afterthought is becoming the production version of "we recycle." It calms the conscience without changing the maths.
We do offset what we can't reduce, and we use AdGreen's tooling to measure the input number that drives the offset. Reduce, measure, then offset what's left. That's the order.
If sustainability is now a real procurement criterion, and the Ad Net Zero data says it is for 61% of supporters at Accelerator tier, the questions in the briefing template haven't caught up with the data.
Five we'd welcome:
We can answer all five with numbers. So can a handful of other production companies. If yours can't, that's the data point.
Tungsten has a sustainability mini-campaign coming in the back half of 2026. This piece is the warm-up. The campaign will publish the actual quarterly numbers, the renewable supply certificate, and AdGreen Early Insights comparisons across recent shoots.
On its own, showing the working doesn't reduce a single tonne. What it does is make production options comparable, which is what clients now need.
If you'd like the working on a specific brief before you commission, ask. We'll send it.
