The FLAG Frontier: Decoding Your Scope 3 Land-Based Emissions

Many organisations with science-based targets are now facing their next great challenge: Forest, Land, and Agriculture (FLAG) emissions. If your business buys food, timber, or other land-based commodities, you are now expected to account for and reduce these complex emissions. It’s a significant task, moving beyond the familiar territory of factory energy use and into the messy, often opaque world of global agricultural supply chains.

The core problem is that FLAG emissions are fundamentally different. They don’t come with a neat monthly invoice or a meter reading. They are the result of complex biological processes and land-use changes happening thousands of miles away, often several tiers deep in your supply chain. This is where most sustainability and procurement teams get stuck.

Why the best intentions stall

Teams often get bogged down for a few common reasons. First is the pursuit of perfect data. They search for a single, precise emissions factor for a tonne of soy from a specific region, but it doesn't exist. This leads to analysis paralysis, where the complexity of life-cycle assessments and academic models prevents any practical first steps.

Second is a disconnect from commercial reality. The sustainability team might spend six months calculating a detailed FLAG footprint, only to present it to a procurement team that has no practical way to act on it. The data, however accurate, doesn't translate into a clear signal for a buyer who needs to make a sourcing decision next week. The report gets filed, but purchasing patterns remain unchanged.

The goal isn't a perfect academic paper on your historical FLAG footprint. The goal is to give your buyers enough information to make a better decision before the next purchase order is signed.

Finally, there’s the issue of supplier leverage. Many companies feel powerless. How can a European retailer influence farming practices in South America? They resort to sending generic questionnaires to thousands of suppliers, leading to low response rates and unactionable data. The effort is huge, but the impact is minimal.

What good looks like

Getting FLAG right is not about achieving accounting perfection. It’s about building a system for informed prioritisation. A successful programme shifts the focus from chasing a perfect number to identifying the greatest risks and opportunities for reduction.

Good looks like knowing that 80% of your deforestation risk lies with five key suppliers of a single commodity. It means you can stop sending mass surveys and instead engage those five suppliers in a meaningful conversation about traceability and regenerative practices.

Consider a global food company. Instead of trying to calculate the exact footprint of every ingredient, they start by mapping their spend against high-risk commodities like palm oil, beef, and cocoa. They blend public data from sources like the FAO with their own procurement records to build a heat map. This immediately shows them that their Brazilian beef and Indonesian palm oil suppliers are the primary hotspots. This insight allows them to focus all their energy on targeted initiatives, such as funding on-the-ground verification programmes and rewarding suppliers who can prove deforestation-free sourcing. Action follows insight.

A practical playbook for getting started

Tackling FLAG emissions doesn’t require a multi-year consultancy project. It requires a pragmatic, commercially-grounded approach.

First, map your exposure, don’t measure it. Begin with your procurement data. Identify your FLAG-relevant commodities and where you buy them from. Use this to create a high-level risk profile. This initial hotspot analysis is your starting point, and it can be done in weeks, not months.

Next, segment your suppliers. You cannot engage with thousands of suppliers in the same way. Group them into tiers based on their commodity, region, and strategic importance. Your top-tier suppliers in high-risk areas require a direct, collaborative approach. The long tail might only need clear communication of your sourcing standards.

Then, ask for operational data, not emissions factors. Most suppliers cannot give you a precise carbon footprint, but they can tell you if their palm oil is RSPO-certified or if they can trace their soy to the farm level. These are practical, verifiable data points that serve as excellent proxies for performance. A good platform can help you collect and interpret this messy data, turning it into a clear signal for your procurement teams. This is how you embed sustainability into the commercial engine of the business.

The single best step to take this quarter

Forget trying to solve everything at once. The most valuable first step you can take is to pick one high-risk commodity and trace it. Choose a product that is material to your business and known to have a high FLAG impact, like soy or beef. For the next 90 days, make it your team's mission to understand that specific supply chain.

Who are the traders? Which regions does it come from? How far back can you get reliable information? This simple exercise in tracing will teach you more about your real-world FLAG challenges than any theoretical calculation. It builds the practical muscle needed for genuine supplier engagement and reveals where to focus your efforts for the biggest climate impact.

Ultimately, progress on FLAG emissions comes from action, not just accounting. It’s about prioritising your efforts, engaging the right suppliers, and using your commercial leverage to drive change where it matters most. Stop searching for the perfect number and start investigating your most critical supply chain. That is the pathway to real decarbonisation.
