In 2025, sustainability isn’t a nice-to-have – it’s an essential part of how agencies work, pitch, and build brands.
Clients are increasingly demanding transparency, credible action, and climate-conscious solutions across their supply chains. For agencies, that means sustainability must be part of every supplier conversation—not just the biggest contracts, but every partner you bring into your work.
Here are 10 smart questions to help agencies vet suppliers and keep sustainability front and centre:
1. What are your sustainability policies and certifications
Start with the basics. Ask suppliers to share any environmental policies, commitments, or third-party certifications (e.g. ISO 14001, B Corp, FSC). Documentation shows they’re serious – not just talking the talk.
2. Can you provide data on your carbon footprint?
It’s not enough for suppliers to claim they’re “eco-friendly.” Request measurable data on their carbon emissions and reduction plans, ideally verified by credible sources.
3. How do you source your materials?
Sustainable sourcing is critical. Whether it’s paper, fabrics, digital hardware, or packaging – understand where materials come from and whether ethical, low-impact options are being prioritised.
4. What steps are you taking to reduce waste?
From manufacturing processes to shipping, find out how suppliers minimise waste, avoid single-use plastics, and implement recycling or circular solutions.
5. How do you manage energy consumption?
Ask about energy sources, efficiency measures, and renewable power usage. Suppliers who invest in green energy are actively lowering their environmental impact.
6. Do you have sustainability goals for the next 3-5 years?
Future-proof your partnerships. Suppliers should have clear targets for improving sustainability, with timelines and accountability built in.
7. How do you ensure fair labour practices?
Sustainability isn’t just environmental – it’s social too. Check that suppliers protect workers’ rights, provide safe working conditions, and pay fair wages.
8. Are your products or services designed for end-of-life recycling or reuse?
Sustainable design thinking matters. Suppliers should offer solutions that consider how products can be disassembled, recycled, or repurposed instead of sent to landfill.
9. Can you share examples of sustainable projects or clients you’ve worked with?
Proof of action speaks volumes. Case studies or client testimonials help verify that a supplier can deliver sustainable outcomes in practice – not just in policy.
10. Are you open to collaborating on sustainability innovations?
The best partnerships are proactive. Find suppliers eager to co-create greener solutions, explore new materials, or help you hit ambitious sustainability targets for your clients.
Every agency has the power and responsibility to shape a more sustainable industry. Asking the right questions isn’t just good for the planet; it strengthens your credibility with clients, protects your brand reputation, and helps you deliver impactful, future-focused work
