Practical Playbook for GHG Protocol & SBTi Action

The Challenge: Action Stalled by Uncertainty

The ground is shifting under the world of carbon reporting. Proposed updates to the GHG Protocol and a contentious debate within the Science Based Targets initiative (SBTi) have left many sustainability and procurement leaders in a difficult position. With 2030 targets looming, the big question is no longer what to do, but whether to act now or wait for the new rules to be written.

This uncertainty creates real commercial risk. Do you invest heavily in a supplier engagement programme, only to find the goalposts have moved in twelve months? Do you double down on collecting specific data points that might become irrelevant? For many, the default response has been to pause, discuss, and wait for clarity. But your emissions are not waiting.

Why Good Teams Get Stuck

It is completely understandable why teams are hesitating. No one wants to waste time and budget on work that needs to be redone. The risk of choosing the 'wrong' path leads to a state of analysis paralysis, where internal meetings multiply, and consultants are engaged to interpret draft guidance.

The focus shifts from practical decarbonisation to theoretical compliance. The conversation becomes about navigating the nuances of potential frameworks rather than reducing actual tonnes of carbon from the supply chain. This is where momentum is lost. While waiting for perfect information, the opportunity to influence this year's procurement decisions, engage critical suppliers, and make tangible progress slips away.

The truth is, 90% of the work required to build a credible decarbonisation plan will remain the same, regardless of the final wording in any new guidance.

What Good Looks Like Today

The organisations making real headway are not waiting. They have recognised that the core principles of effective climate action are independent of reporting standards. They are focusing their energy on the foundational work that delivers value now and prepares them for any future requirement.

This means treating decarbonisation as a commercial and operational priority, not just a reporting exercise. A 'good' approach focuses on three fundamentals: knowing your supplier landscape intimately, embedding an emissions signal into procurement, and collaborating with partners to drive real change.

For example, a large manufacturer we know was concerned about how to account for a key chemical supplier under the proposed new rules. Instead of debating the methodology, they engaged the supplier directly. They discussed the supplier's own transition plans, their move to renewable energy, and how a longer-term contract could support that investment. They uncovered a clear reduction pathway and strengthened a critical commercial relationship. That outcome is valuable, no matter what a new standard says.

A Practical Playbook for Progress

Instead of waiting for perfect clarity, you can take control by focusing on the fundamentals. This four-step playbook will build resilience and drive progress, regardless of external changes.

1. Map Your True Impact: Stop focusing on your entire supply chain. Identify the 20% of suppliers that are driving 80% of your emissions. This is about impact, not just spend. You need to know precisely where your carbon hotspots are before you can do anything about them.

2. Get a Verifiable Baseline: Move beyond spend-based estimates and generic averages. The goal is to get the best possible data for your critical suppliers. Modern platforms are invaluable here, helping to cut through the noise of messy supplier data, identify the true hotspots, and focus your engagement efforts where they will have the most impact.

3. Engage with Commercial Intent: Armed with better data, approach your key suppliers not with a survey, but with a conversation. Understand their targets, their challenges, and their reduction plans. Explore how your procurement power can accelerate their transition. This is about partnership, not just data collection.

4. Equip Your Buyers: Give your procurement team the tools to make climate-aware decisions before the purchase order is signed. This doesn't require a perfect, all-encompassing system. It can start with a simple emissions scorecard for strategic suppliers, allowing buyers to weigh carbon alongside cost and quality.

Your Best First Step This Quarter

The single most effective step you can take is to move from the theoretical to the practical. Forget the noise and the endless debates for a moment.

This quarter, identify the 20 suppliers responsible for the vast majority of your supply chain emissions. Get a verified emissions figure for that critical group, and start a conversation with just three of them about their reduction plans. That's it. That is the start of a resilient, action-focused programme.

Clarity follows action, not the other way around. By focusing on the fundamentals of supplier data, engagement, and procurement, you will be building a decarbonisation engine that is robust enough to handle any changes the future holds.
