The Business Case for Scope 3 Activity Data: Beyond Compliance

During a recent workshop, a Head of Sustainable Procurement asked a question that gets to the heart of a common Scope 3 struggle: “We spend months chasing suppliers for activity data-kilowatt-hours, fuel consumption, logistics metrics. What’s the actual business benefit? Are we just collecting data for a report?”

It’s a fair challenge. Teams are investing enormous effort to move beyond spend-based emissions estimates, believing that more granular data is the only path to credibility. Yet this pursuit of precision often fails to translate into meaningful action. The report gets filed, but the emissions trajectory barely moves.

The Perfection Trap

The core problem is that many organisations fall into a perfection trap. They operate under the assumption that they need perfect, primary activity data from every supplier before they can make a single decision. This approach is flawed because it treats all suppliers equally, ignoring the commercial reality that a small number of suppliers typically drive the vast majority of emissions.

Teams get stuck in a cycle of chasing data from thousands of suppliers, many of whom lack the resources or knowledge to provide it. This leads to low response rates, messy spreadsheets, and a huge administrative burden. The sustainability function becomes a data collection unit, not a strategic driver of change. The connection between a supplier’s data submission and a future procurement decision becomes weak, or disappears entirely.

The goal is not perfect data. The goal is a better procurement decision.

Ultimately, effort gets focused on the suppliers who are most responsive, not necessarily the ones with the biggest climate impact. The annual report might look slightly more detailed, but the business has gained no real advantage or pathway to reduction.

What Good Actually Looks Like

A high-performing sustainability programme doesn’t have perfect data. It has decision-ready data. This means understanding where the real emissions hotspots are and focusing engagement where it will make a material difference.

Good practice involves using a pragmatic mix of data sources. It starts by leveraging existing, verified public data and high-quality models to build a comprehensive baseline in weeks, not months. This immediately reveals the 20% of suppliers responsible for 80% of the emissions. This is where the deep engagement on activity data should be focused. For the long tail of smaller suppliers, a less intensive approach is more effective.

For example, a global manufacturing firm spent a year trying to collect utility bills from over 2,000 suppliers. After getting a low response rate, they changed tack. By first mapping their top 200 suppliers against verified disclosures, they discovered that just 15 strategic partners in their steel and chemical supply chains were responsible for nearly half their Scope 3 footprint. They refocused all their energy on these 15, working collaboratively on reduction plans, and saw a measurable drop in emissions intensity within the first year.

This is what good looks like: prioritisation over perfection, and action over academic data collection.

A Practical Playbook for Action

Moving from data collection to decarbonisation requires a shift in mindset and process. It’s not about abandoning the pursuit of better data, but about applying it intelligently.

First, create your baseline quickly. Use the data you already have-procurement spend, supplier lists-and enrich it with verified public data to map your entire supply chain. Modern platforms can accelerate this, normalising data from multiple sources and providing the tools to prioritise engagement, so teams can focus on reduction, not reconciliation.

Second, tier your supplier engagement. For your high-impact strategic suppliers, invest the time to get primary data and build joint decarbonisation plans. For everyone else, use a lighter touch. Provide them with scorecards, benchmarks, and educational resources, but don’t demand data they don’t have. Make it easy for them to improve.

Third, embed an emissions signal into procurement. The data is only useful if it informs who you buy from and how you work with them. This doesn’t need to be complex. A simple scorecard or emissions rating, visible to buyers during the sourcing process, can guide them toward lower-carbon choices before a contract is signed.

Your Best First Step

If you want to break out of the data collection cycle this quarter, take one simple step: map your top 100 suppliers by spend against their publicly available, verified emissions data.

This single action will give you a clear, evidence-based view of your primary hotspots. It costs very little, requires no supplier chasing, and delivers immediate insight. It allows you to shift the conversation internally from “we need more data” to “here is our biggest opportunity to act.”

Chasing perfect activity data from every supplier is a recipe for burnout. The real business benefit comes from using good enough data to make smarter, faster decisions that lead to a measurable reduction in emissions. Don’t let the pursuit of the perfect report get in the way of actual progress.
