Winter is coming, but it isn’t just the Christmas trees that need to be green

Autumn has its charm: crunchy leaves, golden light, and a socially acceptable increase in hot chocolate consumption. But as we edge closer to the “dark months” (I’m going with that name), the challenges for businesses start to pile up like wet wellies after an ill-advised family walk in the woods.

Yes, we’ve got festive cheer and wonderful sandwiches from M&S to look forward to (Turkey curry? Yes please), but Winter also brings higher energy use, more waste, and the temptation to crank the heating up to tropical levels. So, how do we stay sustainable when the season seems determined to do the opposite?

Let’s unwrap (sorry) some ideas…

Energy Efficiency: Keep warm without melting either the ice caps or you.

Switch to LED Lighting
As daylight disappears, LEDs step in. They’re brighter, cheaper to run, and don’t flicker like a haunted house, though that is also useful this month…

Smart Thermostats
Automate your heating so it’s not on full blast when no one’s around. Seems obvious, but for some it also seems like an alien concept.

Insulate Your Workspace
Drafts are sneaky. Check the seals on windows and doors to keep the warmth in and the bills down.

Encourage Layering
Let’s normalise jumpers, scarves, and fingerless gloves. If everyone’s wrapped up, the heating doesn’t need to be set to “Caribbean.”

(I once worked in an office above a warehouse where the floor was so cold it felt like standing on a glacier. The heating was controlled by someone who didn’t believe in socks. She’d crank it to 28°C, roast us all, then turn it off when she finally admitted it was “a bit warm.” The cycle repeated daily. There’s got to be a better way.)

Employee Engagement: Make it fun, not forced

Workshops & Webinars
Educating staff of how to be sustainable helps too. Even if it is at home, they are still being greener. You can help staff stay warm and efficient with tips on winter energy-saving habits.

Winter Sustainability Challenge
Who can save the most energy? Who’s the recycling hero? Run a friendly competition with eco-themed prizes (reusable mugs, bamboo socks, bragging rights).

Green Gift Guides
Share ideas for sustainable gifts—local, handmade, or just plain useful. Or donations to charities or community projects.

Waste Reduction: Tidy up the tinsel (though waist reduction after Crimbo might be necessary too)

Holiday Recycling Stations
Wrapping paper, packaging, and decorations. Why not set up clearly labelled bins to catch the festive fallout. Bonus points if they’re decorated like presents.*

*no bonus points are actually available, but no one needs to know…

Food Waste: Plan, Portion, Pass It On
If you’re hosting events, plan portions like a spreadsheet wizard. And if there are leftovers, donate them. It’s the season of giving, not binning.

Upcycle Decorations
Before you buy new baubles, take a look at what’s lurking in the cupboard. A bit of glue, glitter, and imagination can turn last year’s decor into this year’s masterpiece. My mum used to recycle last year’s cards into gift tags!

Recycle your tree

Real trees can be recycled and reused by a variety of places. Plenty of charities and councils will collect and re-use and there are also farms that love them to feed to goats. If you want rid, then there will be someone who can use it! I can’t help you with the dropped needles, however.

Long-Term Planning: Not as sexy, but certainly important.

Carbon Audits
Use the quieter months to assess your carbon footprint. It’s like a health check, but for your sustainability.

Set 2026 Goals
New year, new targets. Align with net-zero ambitions or other commitments, e.g. Environment, Social and Governance or ISO and start the year with purpose. These can be really simple too – short, medium and long-term ideas are always great.

Partner with Green Initiatives
Support local environmental charities or tree-planting schemes. It’s good for the planet and great for your reputation.

So, while winter might be dark and chilly, your sustainability strategy doesn’t have to be. With a bit of planning, a dash of creativity, and maybe a few layers, we can all make the season a little greener.
