Why Carbon Reporting Matters for SMEs?

SMEs are under growing pressure to track and share carbon data and Net Zero progress. Getting on top of your carbon footprint can help your business to:

Win work with large clients and partners

Large companies are under pressure to report and reduce their Scope 3 emissions, which means they’re turning to their SME suppliers for carbon data. Carbon footprint requests are now a common feature of tender submissions and procurement policies from big businesses.

Meet investor expectations

If your business has large external investors – especially impact-focused funds – you’ll likely be asked to provide carbon data. As investors need to report on portfolio emissions, managing carbon is becoming part of the growth journey for startups and SMEs.

Win public sector contracts

If you’re bidding for NHS and UK government contracts – or trying to get on public sector frameworks – you’ll increasingly need a Carbon Reduction Plan. This report includes Scope 1, 2 and some Scope 3 emissions, plus a published Net Zero target.

🚧What’s Holding You Back?

Most SMEs don’t have a dedicated sustainability team, and many struggle to get started with carbon reporting. Here are the common challenges we see:

You don't have the in-house expertise

Carbon accounting can be complex. What data do you need? What scopes matter? Without guidance, it’s hard to know you’re doing it right – or in a way that clients and regulators will accept.

You don’t have the time

Carbon reporting often lands on someone who already has a full workload – from Ops leaders to Sales Director. This means it gets pushed down the list – until a client or funder suddenly needs it.

You don’t want to get it wrong

There’s a real reputational risk in publishing numbers or targets that don’t hold up scrutiny. You need confidence that your data and approach are credible.

Why Work with Seedling to Measure and Report Carbon?

All you need to measure, report, and improve your carbon footprint – built for busy teams  – with expert support at every step.

Measure your footprint properly

We guide you through collecting the right data and calculating your carbon footprint across Scopes 1, 2 and 3. Where possible, we use activity-based methods for greater accuracy – not just spend estimates or generic assumptions.

Generate the reports you need

Create clear, professional reports for tenders, investors, or frameworks like SECR, B Corp and Carbon Reduction Plans (PPN 006 & 06/21). All aligned with the GHG Protocol, and easy to share with clients or leadership.

Track progress and take action

Set a Net Zero target, build a reduction plan, and model different scenarios. You’ll get one-to-one support from a Seedling adviser, plus a platform that makes tracking and sharing progress simple.
