Why net zero matters for small businesses
Net zero is no longer just a large corporate concern. Supply chain requirements, procurement frameworks, and customer expectations are increasingly pushing sustainability obligations down to SMEs. Even if your business isn’t legally required to report emissions today, understanding your carbon footprint puts you ahead of what’s coming.
Start with a carbon baseline
Before you can reduce emissions, you need to know what they are. A net zero assessment measures your Scope 1 emissions (direct, gas, fuel), Scope 2 emissions (purchased electricity), and where possible Scope 3 emissions (supply chain, business travel, waste). For most small businesses, Scope 1 and 2 are the practical starting point.
The biggest levers for most small businesses
For most SMEs, the biggest emission sources are energy use in buildings and business travel. Switching to a renewable electricity tariff, improving building insulation, and reducing car and flight travel will move the needle more than anything else.
Set a realistic target
You don’t need to commit to net zero by 2030 to make meaningful progress. Setting a target to reduce emissions by 30% over five years, with a longer-term net zero commitment, is credible and achievable for most businesses.
What about offsetting?
Carbon offsetting, paying for emissions reductions elsewhere to compensate for your own, is increasingly scrutinised. Use it as a last resort for residual emissions you genuinely cannot eliminate, not as a substitute for reducing your own footprint.
Do you need a formal plan?
If you’re bidding for government contracts over £5 million, yes, a Carbon Reduction Plan is a legal requirement under PPN 06/21. If you need to report under the Streamlined Energy and Carbon Reporting scheme, SECR reporting support is available. For most small businesses, a simple internal action plan is enough to get started and demonstrate progress to clients and stakeholders.
