Your Supply Chain Isn't As Green As You Think

The illusion of action: Why asking suppliers to use renewable electricity isn't enough

Many organisations have an ambitious target: 100% renewable electricity across their operations and supply chain by 2030. It’s a clear, commendable goal. The first step often seems obvious, too. The sustainability team, supported by procurement, sends a request to all major suppliers: “Please switch to a renewable tariff.”

And then, very little happens.

The initial supplier responses are positive but vague. Months later, the needle hasn’t moved. The spreadsheet tracking progress remains stubbornly unchanged. The organisation has stated its ambition, but has no clear path to achieving it. This is the illusion of action, and it’s where most supply chain decarbonisation efforts get stuck.

Where good intentions get bogged down

Teams stall here not for a lack of will, but because they are caught between a big target and an unmanageable process. The default approach is to treat all suppliers equally, sending mass surveys to gather data on their electricity consumption and contracts. This creates a huge administrative burden before any real work has even begun.

This ‘boil the ocean’ strategy fails for three reasons. First, it drowns your team in low-quality, inconsistent data from thousands of suppliers. Second, it treats a small local service provider with the same weight as a global manufacturing partner whose energy use is a hundred times more significant. Third, it separates the request from any commercial reality. It becomes a sustainability task, detached from the procurement process and the buyer’s relationship.

The result is a programme that measures activity, not impact. You can report how many suppliers you’ve contacted, but you can’t show a meaningful reduction in emissions. The team is busy, but not effective.

The goal is not to get a perfect survey response from every supplier. The goal is to get your highest-impact suppliers to switch to carbon-free electricity.

What a high-impact approach looks like

Effective programmes look entirely different. They are focused, commercially integrated, and supportive. Instead of asking everyone for everything, they prioritise ruthlessly. They accept that 80% of their supply chain electricity emissions likely come from fewer than 20% of their suppliers. All their energy goes into engaging that critical minority.

For example, a large pharmaceutical company realised that just 15 of its 2,000+ active ingredient suppliers were responsible for over 60% of its Scope 3 emissions from electricity. Instead of another mass email campaign, it launched a targeted programme with just those 15. The engagement was a partnership, not a demand. The company offered technical support, shared information on regional green energy providers, and made it clear that a commitment to renewables would be a significant factor in future sourcing decisions.

Within 18 months, nine of those suppliers had signed new energy contracts, and two more were exploring on-site generation. The company had achieved a measurable, material reduction in its carbon footprint by focusing its effort where it mattered most. This is what moving from reporting to reduction looks like in practice.

A practical playbook for driving change

Shifting from broad requests to targeted action requires a clear plan. It’s about using data to apply effort intelligently.

First, identify your emissions hotspots. You cannot do this by looking at spend alone. You need to combine procurement data with emissions factors to see which suppliers, categories, and regions represent your biggest decarbonisation opportunities. A good data platform can make this analysis a matter of days, not months, by helping you interpret messy supplier data and pinpoint the suppliers whose energy choices have a material impact on your footprint.

Second, segment those high-impact suppliers. They are not all the same. Some will be sophisticated organisations with their own climate targets. Others may be smaller firms in regions where renewable energy is less accessible or more expensive. Your engagement strategy must reflect their reality. For some, a simple conversation will be enough. For others, you may need to offer support, education, or facilitate introductions to energy providers.

Third, integrate this into your procurement process. The conversation about renewable electricity cannot be a once-a-year survey. It needs to be part of the commercial relationship-included in quarterly business reviews, sourcing events, and contract renewals. Empower your buyers with the right data so they can have informed conversations. Make it clear that decarbonisation is a key pillar of your supplier relationship management.

Finally, support your suppliers. Frame the transition as a shared goal, not a new compliance burden. Many suppliers want to make the switch but don't know where to start. By providing resources, facilitating knowledge-sharing between suppliers, or exploring aggregated power purchase agreements (PPAs), you can help them overcome barriers and accelerate their journey.

Your best next step

If you want to make real progress this quarter, stop the mass surveys. Use the data you already have to identify the 20 suppliers with the largest electricity footprint in your supply chain. Forget the long tail for now. Focus all your team's energy on starting a constructive, supportive, and commercially relevant conversation with those 20 partners. That single act of prioritisation will achieve more than a thousand survey responses.
