It's Earth Day, and my LinkedIn feed is having a moment. Companies posting about their carbon goals for 2030, influencers sharing tote bag selfies, supermarkets putting little leaves on their packaging. I'm a bit cynical about it by now, but there's one thing I do think about every April 22nd: how much actually changes when one piece of furniture skips the landfill.
Not metaphorically. In kilograms.
The Sofa Math
A standard three-seater sofa in Switzerland weighs around 60 to 80 kilograms. Most are a mix of foam, plywood, steel springs, and synthetic fabric. When that ends up at the Sperrgut collection, almost none of it is recycled in any meaningful way — the foams contaminate the wood, the steel is hard to extract, and the upholstery is mostly destined for incineration.
Producing a new one isn't free either. Cradle-to-shelf estimates I've seen for an average upholstered sofa land somewhere between 80 and 120 kg of CO₂-equivalent. That's the manufacturing, the transport from mostly-Asian factories, the materials. Add another few kilograms for end-of-life processing of the old one.
So when one sofa moves from someone's living room to someone else's living room — instead of one going to incineration and a new one being shipped — you're looking at roughly 100 kg of CO₂ avoided. For one sofa.
That's about the same as driving a car from Zurich to Milan. From handing over a couch.
It's Not Just Furniture
I picked the sofa because it's dramatic, but the same logic runs through almost everything that gets given away on PIKITUP.
A working washing machine that gets passed on instead of replaced: roughly 250 kg of CO₂ avoided, plus around 30 kg of metal that doesn't need to be re-mined and re-smelted. A working laptop? Maybe 200 kg. A bicycle? Smaller, but the embodied energy in the aluminium frame alone makes the math worth doing.
This is the part of climate policy that nobody puts on a poster. Most of the carbon in stuff is in the making of it, not the using. Once a thing exists, every additional year it stays in use is pure win.
Switzerland's Specific Problem
Here's the awkward part. Switzerland is one of the wealthiest countries in Europe, and it shows in our waste numbers. We throw away around 700 kilograms of municipal waste per person per year — among the highest in Europe. We're also good at recycling, but recycling is the consolation prize. Not creating the waste in the first place is the actual goal.
I've written before about Switzerland's waste problem, so I won't re-litigate it here. The short version: we buy a lot, we replace fast, and our streets on Sperrgut day look like a furniture store exploded.
The encouraging part: we're also a small, dense country with great public transport and a culture that already does Brockenhäuser, ZüriZüri-style giveaway corners, and end-of-month "free" piles on the curb. The infrastructure for keeping things in circulation already exists. It just needs to be findable.
What I'm Actually Doing Today
I'm not going to lecture anyone about their Earth Day plans. But here's my own modest list, in case it's useful:
Walk through the apartment with a question. Not "what could I throw out?" but "what's sitting unused that someone else would actually want?" There's almost always something. A bread machine I bought in a phase. A second monitor from when I worked from home more. Skis I haven't touched in two seasons.
Post one thing. Just one. Posting on PIKITUP takes about ninety seconds — photo, location, short description. The map does the work of finding it the right person.
Pick something up that I'd otherwise buy. I need a small side table for the balcony. Instead of ordering one, I'll check what's available in my area for a week first. If nothing turns up, fine. But it usually does.
That's it. No hashtag, no LinkedIn post about my "sustainability journey." Just one sofa not going to incineration, one washing machine getting a second life, one neighbour saving a few hundred francs.
The Honest Bit
Giving away one sofa isn't going to fix the climate. Obviously. The real levers are at the scale of grids, supply chains, and policy. I know.
But the things that scale started somewhere. The reason there's a giveaway culture in Zürich is that thousands of people independently decided their old stuff was worth more in someone else's home than at the bottom of a Mulde. The reason platforms like PIKITUP can exist is that the underlying behaviour is already there.
Earth Day is a fine excuse to add to it. If you've been meaning to clear out that corner of the basement, today is as good a day as any. Someone two streets over needs exactly what's in there.
Happy Earth Day.
