ESG for sole traders and freelancers: is it worth it?

As a sole trader or freelancer, you have no legal duty to produce an ESG report. It becomes worth doing when clients start asking, which is happening more often as larger businesses measure the emissions in their supply chains. A one-person ESG report is short and quick to produce: usually a small carbon footprint, a note of the policies you follow and a few lines on how you work. It takes about 10 to 15 minutes.

So the honest answer to “is it worth it?” is that it depends on who you work for. If your clients are large companies, agencies or public bodies, probably yes.

Why would a freelancer be asked about ESG?

You are part of someone else’s supply chain. That is the whole reason.

There were around 4.3 million UK businesses with no employees at the start of 2025, roughly three quarters of all private sector businesses, according to the government’s business population estimates. Many of them sell to bigger organisations. When those organisations measure their Scope 3 emissions, freelancers and contractors fall into scope as suppliers.

The requests usually arrive in one of these ways:

• A supplier onboarding form from a large client, asking for an environmental policy or your annual emissions
• An agency or consultancy that subcontracts to you and needs your figures for its own report or tender
• A public sector framework with sustainability questions in the application

None of these expect a freelancer to have a sustainability manager. They want a document they can file.

What does ESG look like for a one-person business?

Much smaller than for a company with staff. Here is how the three parts break down.

Environmental. Your footprint mainly comes from business travel and, if you use one, your share of a co-working space. If you work from home with no vehicles, there may be no Scope 1 or Scope 2 emissions to report at all. A short environmental policy covers how you keep travel down, what equipment you buy and how you handle waste.

Social. Most workforce questions do not apply when you have no employees. What remains is how you treat clients and subcontractors, how you handle personal data under UK GDPR, and any community work, pro bono projects or charitable giving.

Governance. A code of conduct covering honesty, conflicts of interest and anti-bribery, plus a note that you are the person responsible for ESG. That is it.

What is a typical freelancer’s carbon footprint?

Smaller than most people expect, with one big exception.

Take a freelance developer working from home in Sheffield. Over a year, they take ten return trains to London for client workshops and fly once to New York for a conference, in economy.

Using the 2026 UK government conversion factors (approximate):

• Rail: ten returns of about 260 km each way is roughly 5,200 passenger km. At around 0.03 kg CO2e per km, that is about 0.16 tonnes.
• Flight: a return London to New York in economy is roughly 11,000 km. With radiative forcing included, that is around 1.3 tonnes.

The single flight accounts for nearly 90% of the footprint. That is very common for freelancers, and useful to know. Swapping one long-haul trip for a video call does more than a year of other changes. Our guide to business travel emissions has more examples.

If the same developer used a co-working desk three days a week, the report would add an estimated share of the building’s energy, worked out from the desk and days used rather than bills. Our guide to co-working desk emissions explains the method.

What about working from home?

The ESG Now footprint includes an estimate of your homeworking emissions, the extra heating and electricity you use because you work at home. It works this out from the days you work at home, using the UK government’s homeworking factor, and the report labels the figure as an estimate.

If you want to understand or check that figure, our guide to working-from-home emissions walks through the calculation.

Is ESG worth the effort for a sole trader?

Weigh it up against who you work with.

Probably worth it if:

• you work with large companies, agencies or public bodies
• you have been asked for an environmental policy or carbon figure before
• you bid for frameworks or tenders
• you want to stand out in a crowded freelance market with clients who care about this

Probably not urgent if:

• your clients are individuals or other small businesses
• nobody has ever asked

Even in the second case, a short environmental policy and code of conduct sitting in a folder costs you nothing and saves a scramble later. The questions only ever arrive with a deadline attached.

What should a freelancer’s environmental policy say?

Keep it to a page. Clients reading it want to see that you know where your impact comes from and that you have a sensible approach. A good freelancer policy covers:

• Your main impacts, usually travel and the equipment you use
• How you travel, for example rail by default for UK trips and video calls where a meeting does not need to be in person
• What you buy, such as keeping laptops and phones for longer, buying refurbished where practical and recycling old kit properly
• Your energy, including whether your home or co-working space is on a renewable tariff
• Who is responsible (you) and when you review it, usually once a year

That is enough to satisfy most onboarding forms.

How to do it quickly

ESG Now is designed so that sole traders skip anything that does not apply. If you tell it you work from home, the premises, vehicle and workforce questions drop away. You answer a few questions about travel, policies and how you work, and that is most of it.

Pick your setup to see roughly what you will be asked:

How long will yours take?

Pick the option that sounds most like your business. You will see a realistic time, what to have nearby and a head start on the questions.

Your estimate

About 10 to 15 minutes

Around 30 short questions, most of them multiple choice

This is about as quick as it gets.

With no office, no vehicles and no premises, most of the environmental section is skipped for you. You will spend most of your time on a few simple yes or no questions about how you work.

Handy to have nearby

• Roughly how many trains or flights you took for work last year
• Whether you have any written policies (it is fine if you do not)

Missing something? Estimates are fine, and you can come back to any answer later.

You will finish with a carbon footprint, a shareable ESG report and a short list of easy wins.
