How to involve suppliers in climate action (and why it matters)

TL;DR

Companies can significantly reduce their overall climate footprint by engaging suppliers in emissions reduction. This article explains how sustainability managers can reduce Scope 3 emissions by setting climate-related expectations for suppliers, what questions to ask, and how to create positive ripple effects across the value chain. It also includes a practical checklist and FAQ.

Why engaging suppliers matters in climate strategy

After reducing your internal emissions, the next biggest opportunity lies outside your walls, in your supply chain. These are known as Scope 3 emissions under the ghg protocol, and for many companies, they represent the largest part of their total emissions.

By asking suppliers to take climate action, you’re not only helping the planet but also strengthening your sustainability reporting and risk management.

What to ask your suppliers about climate action

To evaluate supplier climate maturity and encourage action, ask questions like:

• Do you have a climate policy?

• Do you report scope 1 and 2 emissions?

• Do you measure and report relevant scope 3 emissions?

• Do you have targets to reduce scope 1 and 2?

• Do you have targets to reduce scope 3?

• Do you offset your climate impact?

• How is climate considered in your procurement policy?

• Do you have a sustainable travel policy?

Even if a supplier hasn’t started yet, these questions show them that climate performance matters in your selection process.

Supplier collaboration creates multiplier effects

When suppliers improve their climate performance, the benefits extend beyond your own footprint. One atmoz customer persuaded a european supplier to switch to renewable electricity. That decision didn’t just reduce the customer’s emissions, it also improved climate performance for every other client that supplier serves.

Your action can influence far more than just your own reporting.

Start the conversation even if there’s no existing climate work

Suppliers who haven’t started climate work may simply be waiting for a signal. Your inquiry could be that signal. If you’re not the first to ask, your voice becomes part of growing market pressure. If you are the first, you may be planting the seed that starts real change.

Frequently asked questions (FAQ)

What are Scope 3 emissions?

Scope 3 includes all indirect emissions across the value chain, such as purchased goods, business travel, logistics, and waste. They are often the largest share of a company’s emissions.

Why should I ask my suppliers for emissions data?

Because suppliers play a key role in your Scope 3 footprint. Encouraging them to measure and reduce emissions helps you meet science-based targets and improves your reporting credibility.

Can supplier emissions affect my climate reporting?

Yes. Under the GHG protocol, many supplier-related activities fall under scope 3. Better supplier data leads to more accurate and defensible climate reports.
