Delivery Carbon: What You Can Actually Claim In Public

Delivery carbon is a lane where the talking runs a long way ahead of the measuring. That is now a commercial risk, not only a credibility one. Environmental claims in India sit inside consumer protection law and advertising self regulation, and green claims are increasingly treated the way any other performance claim is treated: you make it, you substantiate it.

So treat this as claim discipline rather than storytelling. Understand where the emissions actually sit, work the lever that matters, and publish only what you can evidence.

Where the emissions actually sit

For an ecommerce order, split the footprint into parts you can influence.

Upstream product. Manufacturing and raw materials usually dominate the total. It is largely outside the operator’s control, but it sets the scale for everything else. If the product is the overwhelming majority of the footprint, a packaging change is a rounding adjustment and should not be presented as more than that.

Line haul. Long distance movement between hubs. Air versus surface is the single largest structural choice available to you. Load factor matters as much as distance, because a half empty vehicle burns the same fuel across fewer orders.

Last mile. The final leg. Driven by drop density, vehicle type, electrification share, and failed delivery attempts. A second attempt is a second last mile, at full cost and full emissions.

Returns. The reverse leg, plus inspection and handling, plus a redelivery where you replace, plus a write off where the unit cannot be resold.

Packaging. Material mass and its embodied energy. Real and measurable, and usually smaller than the transport legs. Brands lead with it because it is the visible part.

That last mismatch is where most greenwashing begins. Not from lying, but from talking about the part the customer can see while the large numbers sit somewhere else.

Returns are the biggest single lever

A returned order does not add a little footprint. It roughly doubles the transport legs, adds a reverse handling step, and in categories like fashion it frequently ends in a markdown or a write off. In a category running a high return rate, returns exceed packaging as an emissions line by a wide margin, and unlike packaging they cost you real money on every single occurrence.

Which is convenient, because the fixes are ones you would run anyway on margin grounds.

• Size and fit guidance on the product page, driven by the return reason codes you already collect.
• Accurate imagery and specification, because the most common return reason in India is not defect, it is expectation mismatch.
• Address quality at checkout, because a failed delivery becomes an RTO, which is a return with no revenue attached at all.
• Delivery date accuracy, because a late order gets refused at the door.
• Return abuse controls on the small number of accounts driving a disproportionate share.

None of this needs an environmental justification to get funded. Present it as margin work that happens to be the largest carbon lever you own. That framing gets it resourced and keeps the claim honest.

Consolidation and the split shipment problem

A split shipment turns one last mile stop into two or three. The usual causes are structural.

• Inventory spread across nodes with no single node able to fill the whole order.
• Marketplace node assignment logic that you do not control.
• Partial availability at pick time.
• Customer behaviour trained by quick commerce to order small and often.

The fixes are inventory placement and order orchestration, not messaging. Improve node level availability for SKUs that get bought together. Add a short hold window where the second line is arriving into the node imminently. Offer a consolidated delivery option with a clear date, but only where you can hold the promise, because a missed promise produces a refusal, which produces a return, and you have now made both the cost and the footprint worse.

Note clearly what you cannot fix. On a marketplace, node assignment and shipment splitting are the platform’s logic. Do not claim a consolidation benefit you do not control.

Offsets and their honest limits

An offset does not reduce your emissions. It funds a claimed reduction somewhere else. That can be worth doing, and it is not the same thing, and the distinction is the entire argument.

Test any offset on four questions. Additionality: would the reduction have happened anyway without your money. Permanence: can the stored carbon be released again later, which is the standing problem with forestry projects. Verification: who audited it, against which standard, and how recently. Double counting and retirement: is the credit retired against your claim and only yours.

Separately, the regulatory direction on offset based claims has been tightening across several markets, and neutrality claims resting on purchased credits attract particular scrutiny. Confirm the current position under Indian advertising and consumer protection guidance before you put a neutrality claim on a website, an invoice or a pack.

Claim discipline: publish only what you can evidence

One rule covers most of it. If you cannot state the boundary, the baseline and the method, do not publish the number.

Defensible, because each one is bounded and measurable.

• We reduced packaging material mass per order by a stated percentage against a stated baseline year, measured in grams per shipped order.
• We move a stated share of domestic volume by surface rather than air.
• We reduced our return rate from one stated figure to another over a stated period.
• We deliver a stated share of last mile orders in named cities using electric vehicles, with the share disclosed.
• Our primary shipper is a mono material recyclable substrate, with the specification available on request.

Not defensible without considerably more work.

• Carbon neutral delivery.
• Eco friendly, green, or planet friendly used as bare adjectives.
• Fully recyclable, where no collection route exists for that material in the markets you actually sell into.
• Compostable, where you cannot name a facility that accepts it.
• Any absolute figure published without a boundary and a baseline.

Apply the same discipline you would apply to a performance claim. State the metric, the period, the comparison and who verified it. If a claim would embarrass you in a regulator’s letter, it should embarrass you on the website first. Misleading claims carry consequences under Indian consumer protection law, and environmental claims have drawn specific guidance from the advertising and consumer protection bodies. Confirm the current text of the applicable guidelines before publishing, and keep the substantiation file somewhere a person other than the author of the claim can find it.
