Introduction
You care about the environment. You run a small business. And you’re probably thinking: I can’t afford expensive green initiatives right now.
I get it. The cost of living crisis is still hurting. Every pound counts.
But here’s the thing, some of the most effective ways to reduce your carbon footprint cost absolutely nothing. In fact, many of them will save you money.
I’m David from Green & Moore Accountancy. We’ve run as a carbon-neutral practice for years, and I’ve helped dozens of UK small businesses reduce their environmental impact without breaking the bank.
This guide shares 10 changes you can make this week. No budget required, No complicated systems, Just practical actions that actually make a difference.
1. Switch to Ecosia as Your Search Engine
Ecosia is a search engine that plants trees with its ad revenue. Every search you make contributes to reforestation projects. They’ve planted over 200 million trees so far.
How to do it:
- Go to ecosia.org
- Click “Add to browser”
- Set as default search engine
Takes about 2 minutes.
Your business probably searches online 50+ times per day. That’s 1,000 searches a month. With Ecosia, those searches actively remove CO2 from the atmosphere.
It works exactly like Google. You won’t notice any difference except the small tree counter showing your impact.
2. Go 100% Digital with Invoicing and Receipts
Stop printing invoices, receipts, and statements. The average UK business uses 10,000 sheets of paper per year. That’s 5 trees, plus the carbon from production and transport.
How to do it:
- Use accounting software (Xero, QuickBooks, FreeAgent all offer free trials)
- Email invoices as PDFs
- Use receipt scanning apps (many are free)
- Store everything in cloud storage
It takes about an hour to set up. After that, it’s actually faster than paper.
Why this matters: I’ve worked with clients who saved £600+ per year just by eliminating paper, printing, postage, and storage costs. Plus, digital records are much easier to find when you need them.
Going paperless isn’t just environmentally friendly—it’s more efficient and cheaper.
3. Turn Equipment Off at Night (Properly Off)
What it is: Switching off computers, monitors, printers, and chargers completely, not leaving them on standby.
How it helps: Devices on standby still use 10-20% of their full power. That’s wasted electricity 16+ hours per day.
How to do it:
- Use plug strips with switches for easy shutdown
- Create an end-of-day shutdown routine
- Turn off wifi routers overnight if appropriate
- Unplug chargers when not in use
Time required: 5 minutes daily
Why this matters: The Carbon Trust estimates businesses waste £1.3 billion annually on energy for devices left on standby. For a small office, switching everything off properly can save £150-300 per year.
That’s reduced emissions and money back in your pocket.
4. Default to Virtual Meetings
What it is: Making video calls your first choice instead of in-person meetings.
How it helps: The average car journey to a meeting produces 400g of CO2 per mile. A 20-mile round trip = 8kg of CO2. Do that weekly and you’re at 416kg per year from one regular meeting.
How to do it:
- Use free tools like Zoom, Google Meet, Microsoft Teams
- Suggest virtual meetings as default in your calendar invites
- Only travel when face-to-face adds genuine value
Time required: Zero—it actually saves you time
Why this matters: Beyond emissions, you save:
- Travel time (2-3 hours per meeting)
- Fuel costs
- Parking fees
- Vehicle wear and tear
- Mental energy from driving
I haven’t driven to a client meeting in three years. It’s better for the planet and my diary.
5. Set Your Printer to Double-Sided Default
What it is: Changing your printer settings so it always prints on both sides of paper.
How it helps: Cuts your paper use in half instantly.
How to do it:
- Go to printer settings/preferences
- Find “two-sided” or “duplex” printing
- Set as default
- Apply to all users if you have staff
Time required: 3 minutes
Why this matters: Even if you can’t go completely paperless yet, this one setting cuts your paper consumption by 50%. Over a year, that’s thousands of sheets saved.
Plus, it makes documents easier to handle—fewer pages to shuffle through.
6. Use Cloud Storage Instead of Email Attachments
What it is: Sharing files via links (Google Drive, Dropbox, OneDrive) instead of attaching them to emails.
How it helps: Email attachments are incredibly carbon-intensive. Every email with a large attachment generates 50g of CO2. The same file stored once in the cloud and shared via link? Negligible ongoing emissions.
How to do it:
- Store files in cloud storage (most have free tiers)
- Share via link instead of attachment
- Set viewing/editing permissions as needed
- One file, many people can access
Time required: 2 minutes per file share (actually faster than attaching) This can take a bit of time to get used to and get out of old habits.
Why this matters: If you send 10 large files per week via email, that’s 26kg of CO2 per year. Cloud sharing eliminates this entirely, plus everyone always has the latest version—no confusion over which draft is current.
7. Switch to a Green Web Host
What it is: Moving your website to a hosting company powered by renewable energy.
How it helps: Traditional data centers use massive amounts of electricity from fossil fuels. Green hosts use 100% renewable energy.
How to do it:
- Check your current host’s sustainability policy
- Popular green hosts: The Green Hosting Company, Krystal
- Contact your web developer to migrate (usually straightforward)
Time required: 1-2 hours including research and migration
Why this matters: Your website runs 24/7. If it’s hosted on fossil fuel-powered servers, it’s constantly generating emissions. Green hosting eliminates this.
We use The Green Hosting Company for greenandmoore.co.uk. The switch took 90 minutes and cost the same as our previous host.
8. Optimize Your Email Habits
What it is: Deleting old emails, unsubscribing from junk, and keeping your inbox lean.
How it helps: Every email stored on a server requires energy to maintain. Unnecessary emails = unnecessary energy use.
How to do it:
- Delete old emails you don’t need
- Unsubscribe from newsletters you never read
- Use tools like Cleanfox or Unroll.me (free)
- Archive or delete automatically with email rules
Time required: 30 minutes initially, then 5 minutes weekly
Why this matters: The average UK worker has 12,000 emails stored. Many haven’t been opened in years. Deleting these reduces your digital carbon footprint and makes your inbox more manageable. Less emails can give you more clarity and less stress.
Think of it as decluttering, but for the planet.
9. Set Heating or Air Con 1 Degree Lower/Higher
What it is: Adjusting your thermostat by just one degree.
How it helps: A 1-degree change reduces energy use by 8-10%.
How to do it:
- Check your current thermostat setting
- Lower heating by 1°C (from 21°C to 20°C is typical)
- Raise air conditioning by 1°C in summer
- Adjust gradually so people barely notice
Time required: 30 seconds
Why this matters: For a small office, this one change saves approximately:
- £150-200 per year on energy bills
- 250kg of CO2 annually
You probably won’t even notice the temperature difference. But your bills and carbon footprint will definitely show it.
10. Buy Nothing New for One Month
What it is: A 30-day challenge to only use what you have or buy secondhand/refurbished.
How it helps: Manufacturing new products is incredibly carbon-intensive. Buying refurbished or doing without eliminates these emissions entirely.
How to do it:
- Before buying anything, ask: “Do I already have something that works?”
- Check secondhand options first (eBay, Facebook Marketplace, Gumtree)
- Borrow or rent instead of buying
- Delay purchases to see if you still need them
Time required: Ongoing practice
Why this matters: The circular economy (reuse, repair, repurpose) is one of the most powerful climate solutions available. As a small business, every purchasing decision either supports this or works against it. If you do need to buy new try investing in better quality items so they will last longer.
Personal example: Every piece of tech at Green & Moore is refurbished. Saved thousands of pounds and prevented multiple devices from landfill. They work perfectly. We have a policy of reuse, repair or refurbished first.
Bonus Tips: Small Actions, Big Impact
Once you’ve tackled the main 10, here are more free changes to consider:
- Reusable everything: Water bottles, coffee cups, lunch containers, shopping bags
- Natural light first: Open blinds before turning on lights
- Batch your errands: If you must drive, combine multiple stops in one trip
- Cold water washing: If you have workplace facilities, wash at 30°C or cold
- Repair before replace: Fix broken items instead of buying new
How to Measure Your Impact
You don’t need fancy software to track your progress. Here’s a simple approach:
Month 1: Baseline
- Estimate current paper use (packs purchased)
- Note average fuel costs for travel
- Record energy bills
- Count typical miles driven for work
Month 2-3: After Changes
- Track the same metrics
- Calculate reductions
- Celebrate the wins
Many businesses see 20-30% reductions in their carbon footprint within three months just from these free changes.
Why Small Businesses Matter
You might think: “I’m just one small business. How much difference can I really make?”
Here’s the truth: Small businesses make up 99% of UK businesses and employ 60% of workers. Together, we have enormous collective power.
If every small business in the UK implemented even half of these 10 changes, we’d prevent millions of tonnes of CO2 emissions annually.
Your actions matter. Your leadership matters. Your choices ripple out to your friends, customers, suppliers, and competitors.
What to Do Next
You don’t need to implement all 10 changes at once. That’s overwhelming and unsustainable.
Instead, try this:
This Week:
- Choose 2 actions from the list above
- Implement them fully
- Notice how easy they actually are
Next Week:
- Add 2 more actions
- Keep the first 2 going
Within a Month:
- You’ll have all 10 running
- They’ll feel like normal practice
- You’ll wonder why you didn’t do this sooner
Common Objections (And Honest Answers)
“Will this really make a difference?”
Yes. If you implement all 10, you’ll likely reduce your business carbon footprint by 25-40%. That’s significant.
“I’m too busy to think about this right now.”
I understand. But most of these take less than 5 minutes to set up, then they run automatically. The time investment is minimal.
“My customers don’t care about sustainability.”
They might care more than you think. 73% of UK consumers now prefer businesses that prioritize sustainability. It’s becoming a deciding factor.
“What if I can’t do all of them?”
Do what you can. Three changes are better than zero changes. Progress over perfection.
