Large B2B customers increasingly require suppliers to report carbon emissions including logistics. While mandatory carbon reporting currently applies to larger businesses, SMBs in B2B supply chains are under growing pressure to provide emissions data. AskBiz calculates your delivery carbon footprint from carrier and route data automatically, giving you the numbers without the spreadsheet work.

The Customer Email That Changed Everything#
In early 2024, a Yorkshire-based food packaging supplier received a supplier questionnaire from one of their largest customers — a supermarket chain. The questionnaire included a section on carbon emissions: Scope 1 (direct emissions from owned vehicles), Scope 2 (emissions from purchased electricity), and Scope 3 (supply chain emissions, including the carbon footprint of logistics operations). The packaging supplier had never calculated any of this. They had two months to respond or risk being removed from the approved supplier list. This experience is increasingly common. Large businesses with mandatory carbon reporting obligations — the UK TCFD (Task Force on Climate-related Financial Disclosures) requirements and the upcoming CSRD (Corporate Sustainability Reporting Directive) for larger EU-registered companies — need emissions data from their supply chains, including SMB suppliers. If you supply large businesses, carbon reporting is moving from optional to expected to contractually required faster than most SMBs have recognised.
Mandatory vs Voluntary Carbon Reporting for UK SMBs#
Current mandatory carbon reporting requirements in the UK apply primarily to larger businesses. Mandatory greenhouse gas (GHG) reporting under the Companies Act 2006 (Strategic Report) requires quoted companies, large private companies (turnover over £36 million, balance sheet over £18 million, and more than 250 employees), and LLPs meeting similar thresholds to report GHG emissions. Most SMBs fall below these thresholds and face no current legal requirement to report carbon emissions. However, voluntary reporting is increasingly required by: large customer procurement processes (as described above), access to certain finance instruments (green loans, sustainability-linked bonds), and B2B platform requirements (Alibaba, Amazon Business, and some marketplaces are introducing supplier sustainability requirements). Even if reporting isn't legally mandatory for your business today, having the data ready is increasingly important for commercial reasons.
Scope 1, 2, and 3: What Applies to Your Logistics#
The GHG Protocol's three Scope categories structure how carbon emissions are classified. Scope 1 for logistics: direct emissions from vehicles you own or operate — your delivery vans, forklifts. Calculated from fuel consumption data (each litre of diesel produces approximately 2.54kg of CO2 equivalent). Scope 2: emissions from purchased electricity — your warehouse lighting, electric forklifts, electric vehicle charging. Calculated from your electricity consumption and the UK grid carbon intensity factor (currently approximately 0.21 kg CO2 per kWh and falling). Scope 3: indirect emissions from your supply chain — the carrier services you purchase. When DPD delivers your parcels, the emissions from their vehicles that are attributable to your shipments are Scope 3. These are calculated using carrier-provided emissions factors (kg CO2 per parcel-km) or industry standard emission factors. AskBiz calculates Scope 1 (from your fuel card data), Scope 2 (from your electricity bills if provided), and Scope 3 logistics emissions (from carrier shipment data using published carbon intensity factors) automatically.
How Carriers Calculate and Share Emissions Data#
All major UK and European carriers are now required to provide carbon emissions data for shipments, driven by the EU Regulation on Carbon Accounting for Transport (implementing ISO 14083). DPD provides a CO2 Report per shipment through their business portal, showing kg CO2e per parcel based on their vehicle mix and route efficiency. Royal Mail provides annual carbon emissions statements for business accounts, with per-parcel intensity factors. DHL has its GoGreen Plus product which attributes specific emissions offsetting to each shipment. Evri provides carbon data through their business portal. For own-fleet deliveries, you calculate emissions from fuel consumption data. AskBiz integrates with carrier carbon reporting APIs and standardises the data across carriers, so you get a consolidated Logistics Carbon Report that covers all delivery channels in a consistent methodology.
Reducing Your Logistics Carbon Footprint: The Practical Measures#
Carbon reduction in logistics follows the same hierarchy as cost reduction — and many of the actions that reduce emissions also reduce cost. Route optimisation reduces miles driven and therefore fuel consumption and emissions — the 15-20% mileage reduction from optimised routing translates directly to a 15-20% reduction in Scope 1 fleet emissions. Carrier selection: carriers with higher proportions of electric or alternative-fuel vehicles have lower per-parcel carbon intensity. DPD has committed to 30 UK cities with zero-emission last-mile delivery. Royal Mail uses 3,000+ electric delivery vehicles. Requesting these routes specifically reduces your Scope 3 emissions. Packaging right-sizing reduces the dimensional weight of shipments, which reduces fuel consumption per parcel — a packaging optimisation benefit that extends to carbon reduction. Consolidating orders: reducing delivery frequency (fewer, larger shipments to regular B2B customers) reduces total emissions per unit delivered.
Carbon Offsetting: What's Credible and What's Not#
Carbon offsetting — paying for carbon reduction projects to compensate for your own emissions — is controversial but remains a practical tool for businesses that want to report net-zero or carbon-neutral operations. Credible offsets should be: verified by a recognised standard (Gold Standard, Verified Carbon Standard, or Plan Vivo), additional (the project wouldn't have happened without offset funding), and permanent (the carbon won't be released back into the atmosphere). Tree-planting schemes are the most common and most criticised form of offset — trees take decades to mature and are vulnerable to fire or disease. Higher-quality offset projects include methane capture from landfill, clean cookstove distribution, and direct air capture. Several carriers offer bundled offsetting (DHL GoGreen, DPD Carbon Neutral). For SMBs, purchasing carrier-level offsets is simpler than buying offset credits independently. AskBiz tracks your total logistics carbon footprint and connects to your chosen offset programme so your net emissions figure is calculated automatically.
Reporting to Customers: What Format They Expect#
When large customers ask for emissions data, they typically want: total Scope 1 + 2 + 3 emissions in tonnes CO2 equivalent per year, broken down by category. Logistics-specific data: emissions per £1,000 of goods delivered, or per unit delivered, to allow comparison across their supply base. Methodology disclosure: which emissions factors were used, which reporting standard was followed (GHG Protocol is the most widely accepted). Trend data: are your emissions going up or down year-on-year, and what measures are you taking to reduce them? AskBiz generates a Supplier Carbon Report in GHG Protocol format that answers all of these questions from your operational data — suitable for submission to customer procurement teams without requiring specialist sustainability consultancy.
Start Measuring Now, Even If You Don't Report Yet#
The businesses that will be best positioned when carbon reporting becomes a commercial requirement are the ones that started measuring their logistics emissions early — not to report now, but to establish a baseline, understand where their emissions come from, and begin making the operational decisions that reduce them. AskBiz gives you the tools to calculate your logistics carbon footprint from the data you already have — carrier shipment data, fuel card transactions, and route records — without requiring a sustainability team or specialist software. Start tracking your carbon footprint today, and you'll have years of trend data when your customers start asking for it.
