Scope 3 emissions are the part of your carbon footprint that most companies quietly dread. They sit outside your direct operations, spread across hundreds of suppliers, logistics partners, employee habits, and the way customers eventually use or dispose of your products. For many organizations, scope 3 accounts for the vast majority of their total greenhouse gas footprint, sometimes well above 70%. That’s a lot of carbon sitting in places you don’t directly control.
The good news is that “hard to cut” doesn’t mean impossible. There are practical, high-impact moves you can make right now to start bringing that scope 3 carbon footprint down, without needing to overhaul your entire business overnight. Here are seven quick wins to get you moving.
Why scope 3 emissions are the hardest to cut
Unlike scope 1 and scope 2 emissions, which come from your own facilities and the energy you buy, scope 3 emissions live in your value chain. That means you’re relying on other organizations, your suppliers, freight partners, employees, and customers to change their behavior. You can influence them, but you can’t mandate it the way you can with your own operations.
There’s also a data problem. Collecting accurate emissions data from dozens or hundreds of suppliers is genuinely difficult. Many suppliers don’t measure their own footprint, let alone share it. This makes it hard to know where to focus first, which is exactly why getting the basics right early on matters so much.
Audit your supplier emissions data first
Before you can reduce anything, you need to know where the emissions actually are. A supplier emissions audit is the foundation everything else builds on. Without it, you’re essentially guessing which actions will have the most impact.
Start by mapping your supply chain and identifying which suppliers represent the largest share of your spend and activity. Then request whatever emissions data they have available, even rough estimates are better than nothing at this stage. Many suppliers are further along than you might expect, particularly larger ones who are already responding to customer requests or regulatory pressure like the CSRD. The audit doesn’t need to be perfect to be useful. A reasonable picture of where your emissions are concentrated is enough to start making smart decisions.
Prioritise high-impact spend categories
Not all spend categories carry the same carbon weight. Some areas of your procurement, such as raw materials, manufacturing, and energy-intensive goods, typically drive far more emissions than others. Focusing your early efforts on these high-impact categories is one of the fastest ways to make meaningful progress on your scope 3 carbon footprint.
The GHG Protocol’s scope 3 standard identifies 15 categories of scope 3 emissions, and most organizations find that just a handful account for the majority of their impact. Once your audit gives you a clearer picture, rank your spend categories by estimated emissions intensity and start there. Trying to tackle everything at once tends to dilute effort and slow progress. Going deep on your top two or three categories first is a much more effective approach.
Engage key suppliers with clear emission targets
Supplier engagement sounds simple, but it’s one of the areas where many companies stall. The key is moving from vague sustainability conversations to specific, measurable expectations. That means setting clear emission reduction targets and communicating them directly to your most significant suppliers.
You don’t need a perfect framework to start. Ask your top suppliers whether they’ve set Science Based Targets (SBTi) or whether they report through CDP. These are widely recognized frameworks that give you a consistent basis for comparison. For suppliers who aren’t there yet, share your targets and offer support rather than just issuing demands. Suppliers who feel like partners in the process are far more likely to engage meaningfully than those who feel like they’re being audited. Building these relationships now also gives you a stronger position as reporting requirements tighten under frameworks like the CSRD.
Switch to low-carbon logistics and freight options
Logistics is one of the more actionable areas of scope 3, because the alternatives are increasingly available and often not as expensive as people assume. Road freight, and air freight in particular, carries a significant carbon cost compared to rail or sea, and switching modes where feasible can produce noticeable reductions relatively quickly.
Beyond modal shift, look at how you’re consolidating shipments. Fewer, fuller loads almost always mean lower emissions per unit than frequent partial shipments. If you work with third-party logistics providers, ask them directly about their decarbonization plans and what lower-emission options they can offer. Some providers now offer verified carbon intensity data by route, which makes it much easier to build emissions considerations into your procurement decisions alongside cost and lead time.
Redesign procurement policies for lower embodied carbon
Procurement policy is one of the most underused levers for reducing scope 3 emissions. Most procurement teams optimize for cost, quality, and delivery, which makes sense, but adding embodied carbon as a formal evaluation criterion changes the decisions you make at the source.
This doesn’t mean always choosing the most expensive low-carbon option. It means making carbon visible in the decision-making process. Practical steps include requiring suppliers to provide product-level carbon data, weighting lower-carbon options in tender evaluations, and setting minimum thresholds for high-impact categories over time. When procurement teams have clear guidance and the right tools, they can make purchasing decisions that reduce your scope 3 footprint without compromising on quality or value.
Cut business travel and employee commuting emissions
Business travel sits in scope 3 category 6, and employee commuting sits in category 7. Both are areas where organizations often have more influence than they realize, especially given how much working patterns have shifted in recent years.
For business travel, the quick wins tend to involve setting a clear internal hierarchy: virtual meetings first, rail second, short-haul flights only when necessary, and long-haul flights requiring explicit justification. For commuting, incentivizing public transport, cycling, or carpooling schemes can move the needle, as can maintaining flexible working arrangements that reduce the number of days employees need to travel at all. Neither of these requires a dramatic cultural overhaul. Clear policies and the right incentives go a long way.
Use product design to reduce downstream emissions
Downstream emissions, the emissions that occur when customers use or dispose of your product, often represent a significant but overlooked chunk of scope 3. For products that consume energy in use, such as electronics, appliances, or vehicles, this category can dwarf everything else in your value chain.
The most effective intervention happens at the design stage. Products designed to use less energy, last longer, be repaired rather than replaced, or be recycled at end of life all generate lower downstream emissions. This is where life cycle thinking becomes genuinely valuable. Even small design changes, such as reducing standby power consumption or switching to more recyclable materials, can have a compounding effect across millions of product uses. It’s also worth noting that as the EU Taxonomy and related regulations continue to evolve, downstream emissions performance is becoming increasingly relevant to how products are classified and reported.
When to bring in a sustainability expert
There’s a point in most scope 3 reduction journeys where internal capacity runs thin. The work becomes more technical, more cross-functional, or simply too time-consuming for a team already stretched across other priorities. That’s a completely normal place to find yourself, and it’s often the right moment to bring in specialist support.
The type of expert you need depends on where you’re stuck. If the challenge is data collection and emissions accounting, a scope 3 emissions reduction specialist can help you build a credible baseline and identify the highest-leverage interventions. If you’re working toward a specific reporting framework like CSRD or preparing for CDP disclosure, you’d want someone with deep expertise in that area specifically. Sustainability is a broad field, and the consultants who do this work well tend to be highly specialized rather than generalists. Matching the right expertise to your specific challenge makes a real difference in the quality of the outcome.
