Executive summary

What your large clients are asking for

How to comply with what Amazon, Inditex and your largest clients are already demanding without losing your composure or credibility.

Timeline

  • Today: Amazon requires ISO 14083 + GLEC with a contractual deadline.
  • 12–18 months: Level 2 mandatory for major retailers (Inditex, Mercadona, Coca-Cola).
  • 2030: 4,000+ companies with SBTi must cut Scope 3 by 25% and pass the requirement down to their suppliers.

Who is this webinar for?

  • Logistics operators that already report emissions but face growing demands for more detail, more frequency and less room for error.
  • Companies with large clients (retailers, distribution) who have public Scope 3 reduction targets and need supplier data to meet them.
  • Operators that participate or want to participate in tenders where emissions data is already an award criterion.
  • Companies at any point on the ladder: from those with only Level 1 to those with one foot in Level 2 and unsure how to move forward.

The core problem

What holds logistics operators back:

  • It is unclear what level each client demands. The first step is not calculating better, it is knowing what you are actually being asked.
  • Activity data (weight x kilometers per shipment) is scattered across systems that do not talk to each other, or in the hands of an external provider that does not share it.
  • The most painful mistake: using averages instead of weight x distance per shipment can make you report up to 90 times more emissions than real, and Amazon uses those numbers before its committee.
  • The organizational problem: Sustainability says it belongs to Operations, Operations says it belongs to Sustainability, IT says it is not their responsibility. While nobody owns it, the client keeps waiting.
  • When the client raises the bar, the number you used to give is no longer valid, and that conversation is very difficult.

The three levels of demand

Level 1: Total corporate footprint. Calculation of total company emissions (Scope 1, 2 and part of 3). GHG Protocol methodology, annual reporting, aggregated data. Required by sustainability reports, EcoVadis, CDP. The problem: the client does not know how much belongs to them.

Level 2: Emissions per client or per service. The client wants to know what share belongs to them, not your total. By transport mode, by route, by shipment type. Methodology: GLEC / ISO 14083. Required by Inditex, Mercadona, Coca-Cola, major retailers. Common mistake: dividing total footprint among shipments, works until the client raises the bar.

Level 3: Emissions per individual shipment + periodic reporting. Footprint per individual shipment. Monthly reporting. Contractually required methodology: ISO 14083 + GLEC Framework 3.0. Amazon sets it contractually with a start date. This is where Amazon is today. And where the market is headed.

Three questions that reveal where the gap is

Question 1: Do you know what level each client is asking for? Not the general level, the actual level, client by client. Most companies have not mapped this. The first step is not calculating better, it is knowing exactly what you are being asked and what you will be asked in 6 months.

Question 2: Is your activity data available? In plain terms: can you tell how much each shipment weighs and how many kilometers it travels? If that data does not exist or is scattered, that is the real bottleneck, even before methodology.

Question 3: Who manages this internally? The most frequent problem is not technical, it is organizational. While nobody has it assigned, the client keeps waiting.

Dcycle's differential value for logistics

  • Correct calculation from the source: footprint per individual shipment using GLEC 3.0, the data Amazon needs, traceable, methodology-backed, not an estimate divided from the monthly total.
  • Real-time AI: ask directly "what are my emissions for Amazon this month?" or "what do I need to do to reduce by 20%?" without exporting to Excel, without waiting for a report.
  • The contrast that changes everything: the correctly calculated figure versus the rough estimate can differ by a factor of 10, 50 or up to 90. That is what is at stake with methodology.
  • Full traceability: every number has its origin, its weight, its distance, its emission factor; the client sees everything in one place.
  • Subcontracted fleet management: ISO 14083/GLEC covers it; the system manages subcontractor data or applies documented proxy factors.

The key mindset shift

It is not about reporting. It is about capturing data correctly from the source: the actual weight of the shipment, the actual kilometers traveled. Because you will need that same data for Amazon, for Inditex, for the next RFP and for the auditor.

A poorly calculated number is not a technical error. It is a credibility crisis with your client.

Top questions from the webinar

What is the difference between Level 1, 2 and 3 emissions reporting?
Level 1 is your total company footprint (annual aggregated data, GHG Protocol): useful for sustainability reports and EcoVadis, but the client does not know how much belongs to them. Level 2 breaks emissions down by client, route or service using GLEC/ISO 14083 methodology: this is what Inditex, Mercadona and Coca-Cola already demand. Level 3 goes shipment by shipment with monthly reporting: this is where Amazon stands today, and where the market is headed.
Amazon has asked us for ISO 14083 + GLEC. What does that mean in practice?
It means an estimate or dividing your total footprint by the number of shipments is no longer acceptable. Amazon wants the footprint of each individual shipment, with actual weight, actual kilometers and a traceable emission factor. And they want it by a contractual deadline, not 'whenever you can'. If you do not have it, the number Amazon presents to its committee is yours, and if it is wrong, the problem is yours.
We are told that using averages can make us report 90 times more emissions. How is that possible?
When you divide your entire fleet's footprint by all the month's shipments, you assign a 2 kg package the same weight as an 800 kg pallet. If you also mix 50 km routes with 1,200 km routes, the error multiplies. The result is that a small shipment may be attributed 90 times more emissions than it actually generated. Amazon uses that number before its sustainability committee. That is where it hurts.
Activity data is scattered across our systems and some providers do not share it. Where do we start?
Before talking about methodology, this needs to be solved. Activity data means weight x kilometers per shipment: without that, no correct calculation is possible. The first step is mapping where that data lives: TMS, ERP, the carrier's spreadsheet, or directly in the subcontractor's hands. If the provider does not share it, ISO 14083 and GLEC allow documented proxy factors, but you must record why and with what criteria.
In our company, Sustainability says it belongs to Operations, Operations says it belongs to Sustainability, and IT wants nothing to do with it. How do we break out of this?
It is the most frequent problem and the one that delays progress the most. The only way out is someone with authority assigning it explicitly, not as a sustainability project, but as a client requirement. When Amazon or Inditex puts it in the contract, it stops being a reporting topic and becomes a business risk. That is the argument that moves Operations and IT: it is not a whim from Sustainability, it is a condition for keeping the contract.
What happens when the client raises the bar and the number we used to give is no longer valid?
It is the most uncomfortable conversation in the industry. If you spent years reporting a Level 1 figure and suddenly the client asks for Level 2 or 3, the new number can be very different, not because you polluted more, but because it is now measured correctly. The key is anticipating: proactively explain to the client that the methodology change changes the number, and that the new figure is more precise, not worse. If you manage it first, you control the narrative. If the client discovers it on their own, you lose credibility.
