Tendering: Why Sustainability matters commerically
If your business supplies larger companies or the public sector, sustainability is no longer optional. Some SMEs are missing out on work simply because they can’t give the right answers to sustainability questions in tenders or supplier onboarding.
Why does it matter?
Big buyers are under pressure to show they are cutting their supply chain emissions and improving ethical practices. For the public sector, rules like PPN 06/21 require suppliers to have a clear carbon reduction plan. Many large private companies are also introducing supply chain charters that set minimum sustainability standards.
If you can’t meet these expectations, you risk losing contracts to competitors who can.
The questions you’re likely to face
Do you measure your carbon footprint?
What are you doing to cut energy or waste?
Do you have a sustainability or environmental policy?
How are you engaging staff or suppliers in sustainability?
Can you show evidence of progress?
Even if you’re not bidding for public sector work, it’s common for large customers to include these questions in supplier reviews or tender packs.
Quick wins for SMEs
You don’t need a 50-page strategy to start winning work. A simple, credible one-page sustainability statement can make a big difference:
Include basic baseline data – for example, annual energy use or waste volumes.
List 3–5 specific actions you’re taking, such as energy audits, switching to LED lighting, or introducing recycling.
Keep evidence ready – bills, certificates, or photos of improvements.
Be honest. Buyers prefer realistic progress to vague claims, and overclaiming risks being seen as greenwash.
The takeaway
Think of sustainability as protecting and growing revenue, not just a “nice to have.” If a key customer introduces a new supply chain charter, or you’re asked to complete a sustainability section in a tender, being prepared could be the difference between winning or losing the work.
