Net Zero for Wholesalers: Necessary, Achievable, but Unproven at Scale

Sir Chris Hohn, founder of the £60bn hedge fund TCI Fund Management, has put the distribution sector's climate question in one sentence: "If you aren't decarbonising your business, you could go out of business."

Hohn, who has given away more than £1bn of his personal wealth to fight climate change, made the remark as reported in The Sunday Times, adding that global warming is "blindingly obvious" and that any idiot can see climate change accelerating. The quote anchors the latest column from Gilroy, a wholesale-sector commentator, whose central claim is blunt: running wholesale distribution at net zero is not a nice to have but essential. And, he asserts, it has been achieved many times.

That assertion carries weight. But no measured example follows it.

What is actually required, and by when?

The regulatory deadline is fixed. The UK has committed to net zero greenhouse gas emissions by 2050 under the Climate Change Act 2008, with many other countries holding similar targets. Wholesale businesses sit in the middle of supply chains — intermediaries between manufacturers and retailers — and while their direct emissions run lower than manufacturers', they drive substantial emissions through transport, warehousing, procurement, packaging and supplier relationships.

Measurement follows the Greenhouse Gas Protocol, which sorts emissions into three categories: Scope 1 (direct, from owned vehicles and heating), Scope 2 (indirect, from purchased electricity, heating and cooling) and Scope 3 (everything else in the value chain — purchased goods, transport, commuting, waste, customer use). For wholesalers, Scope 3 is usually the largest share of the footprint, because products are sourced globally from manufacturers and distributed onward. That is precisely the scope a wholesaler controls least.

The column lists six areas of focus: energy-efficient warehouses, renewable energy, sustainable transport, waste management, digital technology and employee engagement.

Where the economics look testable

Gilroy is strongest where costs and savings meet. Warehouses consume considerable electricity through lighting, refrigeration, heating, ventilation and automation. LED systems cut consumption and last longer than fluorescent lighting; motion sensors stop lighting empty aisles. Replacing gas heating with heat pumps running on renewable electricity can substantially cut emissions, while insulation, smart thermostats and energy management systems trim use further.

On energy supply, rooftop solar photovoltaic panels suit large warehouses because roof space is extensive, and renewable investments often carry relatively short payback periods thanks to falling technology costs and rising energy prices. Some businesses sign Power Purchase Agreements — contracts buying renewable electricity directly from wind or solar farms — while others buy certified renewable supply; battery storage can shift daytime generation into overnight use.

Each measure plausibly lowers operating cost as well as carbon. None comes with a number attached.

The transport problem nobody has solved

Transport is typically the largest source of operational emissions for wholesalers, and here the column concedes the gap between ambition and infrastructure. Electric vans produce zero tailpipe emissions and improve as grids decarbonise. Hydrogen fuel cells may suit heavier, longer-range vehicles — although the infrastructure remains limited. That caveat deserves emphasis: for the articulated trucks that carry national distribution, no mature zero-carbon option is named.

The rest of the transport case is software: route optimisation, AI analysis of traffic and vehicle capacity, consolidated deliveries to avoid part-loaded vehicles, and collaborative logistics where multiple wholesalers share transport resources. These cut fuel, and fuel is a cost line. They do not eliminate it.

Waste, data and people

Waste measures — segregation of cardboard, plastic film, pallets and electronics, better inventory management, demand forecasting, redistribution of surplus food to charities where legally permitted — follow circular economy principles (recovering and refurbishing rather than disposing). Reducing waste frequently lowers both environmental impact and operating cost, the column notes.

Digital tools include IoT sensors monitoring warehouse temperatures and equipment performance, AI flagging inefficiencies, cloud computing replacing physical servers, paperless documentation, blockchain recording product origins so wholesalers can verify supplier claims, and carbon accounting software for setting targets and tracking progress. Verification of supplier claims is a real control point: it addresses Scope 3 data quality, the weakest link in most carbon reports.

Finally, technology alone cannot deliver net zero without employees. Training in efficient driving, energy conservation and sustainable procurement, incentive schemes rewarding innovations, and visible leadership commitment all matter — because line staff see the inefficiencies managers miss.

A 200-year-old comparison, and what it proves

Gilroy reaches back for his proof that large-scale logistics can run on something other than fossil fuel: Waterloo, 18 June 1815. The campaign fed nearly 190,000 soldiers, sustained more than 40,000 horses and kept more than 500 artillery pieces supplied, moving an estimated 6,000–8,000 tonnes of materiel via barges on Belgium's rivers and canals, then several thousand horse-drawn wagons shuttling between depots and the front. A genuinely impressive pre-industrial logistics exercise, he concedes — and unacceptable by modern standards of medicine and food quality.

The comparison is vivid. It is also the column's only concrete case, and it is two centuries old. If net zero wholesale operations have been achieved many times, as claimed, the named, measured, contemporary examples are absent — Scottish wholesalers' net zero case studies are referenced but not detailed.

The column's closing judgement, that operating at net zero is both right and smart, and now urgent, sets the test distributors should apply to any supplier or platform selling decarbonisation: show the Scope 3 data, the payback period, and the verified name.
