From Data to Decisive Climate Action

At a recent event, a Head of Sustainability shared a familiar story. Her team had spent the better part of a year calculating their company's Scope 3 footprint. They had a number, a detailed report, and a set of beautifully designed slides. Then came the inevitable question from the board: “This is great. Now, what are we actually doing about it?”

This is the moment where many well-intentioned climate programmes stall. The focus shifts from measurement to action, and the path forward becomes less clear. The real challenge isn’t getting the number; it’s determining your role in reducing it and making the biggest possible impact with limited resources.

Why good teams get stuck

Many organisations fall into one of two traps that stifle progress. The first is the pursuit of perfect data. Teams spend endless cycles chasing primary emissions data from every single supplier, believing that 100% accuracy is a prerequisite for action. It feels productive, but it’s often a form of procrastination that delays the harder work of engagement and intervention.

The second trap is the ‘peanut butter’ approach: spreading effort evenly across the entire supply chain. Every supplier receives the same survey, the same request, and the same follow-up email. This approach ignores a fundamental reality of supply chain emissions. For most large companies, a small fraction of suppliers-often less than 10%-are responsible for more than 50% of the impact. Treating a global logistics partner with the same level of engagement as a local print shop is a waste of time and political capital.

Underpinning both of these issues is a common organisational disconnect. Sustainability teams are tasked with reducing emissions, but they often lack the commercial leverage to make it happen. That power sits with Procurement, and without a deep partnership between these two functions, requests for change lack commercial weight.

What good looks like

Moving from reporting to reduction requires a shift in mindset. The objective is not to produce a perfect audit of the past, but to influence the future. Good practice is defined by ruthless prioritisation and a tight alliance between sustainability and procurement.

The goal isn't a perfect emissions report. It's a prioritised action plan tied to commercial reality.

Consider the example of a large pharmaceutical company. Their initial analysis revealed that just 40 strategic suppliers accounted for over 60% of their purchased goods and services emissions. Instead of launching a mass survey, they organised intensive, collaborative workshops with just these 40 partners.

The sustainability team provided the emissions data and climate expertise. The procurement team led the commercial conversation, exploring how reduction efforts could be linked to contract renewals, joint innovation funds, and preferred supplier status. The result was a set of co-created decarbonisation roadmaps with clear accountabilities. Within 18 months, they were tracking measurable reductions, not just collecting better data.

A practical playbook for action

Transitioning from measurement to mobilisation doesn't require a bigger budget. It requires a smarter approach.

First, segment your suppliers based on their impact. Use the data you have, even if it’s imperfect, to group them into tiers. A small group of high-impact partners will require deep, strategic engagement. The next tier might benefit from scalable support, like scorecards and peer benchmarks that show them where they stand and how to improve. For the long tail, the focus should be on efficient data collection, using public sources and estimates to minimise the burden. Modern platforms are designed to do this heavy lifting, turning messy supplier data into clear segments and actionable insights.

Second, equip your procurement colleagues for success. They don’t need a 100-page climate report. They need simple, commercially relevant tools. A one-page supplier scorecard showing emissions intensity, reduction trajectory, and a clear benchmark against their peers can transform a standard quarterly business review. It gives buyers the signal they need to make emissions a tangible part of their sourcing and supplier management conversations.

Finally, change the conversation from compliance to collaboration. Instead of asking, “Can you please fill in our survey?”, start asking, “We’ve identified an opportunity to improve efficiency and resilience together. Can we explore it?” Framing decarbonisation as a shared commercial opportunity builds momentum far more effectively than a simple request for data.

Your best first step this quarter

If you want to accelerate your impact, don't launch another data collection campaign. The single most effective step you can take is to book a two-hour workshop with your Head of Procurement.

The only item on the agenda should be your list of the top 20 suppliers by emissions. Go through them one by one and ask two simple questions: What is our commercial relationship and leverage with this supplier? What is one practical conversation we could start next month to encourage progress?

This single meeting will do more to bridge the gap between reporting and action than months of chasing survey responses. It builds the internal alliance necessary for success and shifts the organisation’s focus from counting carbon to cutting it. Your role is not just to measure, but to mobilise. Use the data you have to start the conversations that matter.
