One Stem at a Time: A Bench-Side Carbon Scorecard for UK Bouquets
Sooner or later, someone leans over the counter and asks whether the bouquet is sustainable. The truthful answer is usually 'more than some, less than others', which is not a sentence that sells flowers. The trouble with carbon claims in floristry is that they squash a very tangled supply chain into a sticker. A scorecard is a friendlier tool: not a certificate, just a way of comparing one recipe against another on the same terms.
Why count stems, not bouquets
A bouquet is a bundle of completely different journeys. A British field-grown stem in July might travel thirty miles in a van. A Kenyan rose flies four thousand miles and then takes a truck up the M4. A Dutch tulip in January comes out of heated glass. Average those into a single number and you learn almost nothing about where to intervene.
Score stem by stem and the picture sharpens fast. You can see that three stems in a ten-stem bunch are carrying most of the burden — and that is exactly where swaps pay off. It also gives you a unit to compare with: points per stem, added up and divided by the number of stems, gives you a recipe score.
The four things that move the number
Origin and transport mode. Air freight is the heavyweight. Sea, road and a local van are progressively lighter. As a rough rule, a stem flown in carries many times the transport burden of one driven from a UK grower.
Season. Outdoor-grown, in season, is the lightest version of almost any flower. Heated glass in winter — or imports standing in for a British crop that isn't ready yet — pushes the score up.
Crop and growing method. Hardy field stems do well here: daffodils, dahlias, branches, most foliage. High-input, heavily refrigerated, long-chain crops do not.
Mechanics and packaging. Reusable kit is heavy to make but amortised over hundreds of jobs, so it scores well. Single-use foam, one-trip vessels and layers of plastic wrap add up quietly.
A simple five-band score
Use letters or numbers — numbers are easier at the bench. One is lightest, five is heaviest.
- 1 — UK grown, outdoor, in season, road-delivered.
- 2 — UK grown but cold-stored a while, or near-Europe by road in season.
- 3 — European glass or field, road or sea freight, or a UK crop bought out of season.
- 4 — Flown, but in season and in sensible volume.
- 5 — Flown and out of season, or a high-input crop from a heated environment.
It is rough. It is also defensible, because you are not publishing a number — you are ranking your own recipes against each other.
Worked example: a September shop bouquet
Take a ten-stem bunch: three British dahlias from a grower forty miles away, two Dutch spray roses, two Kenyan roses, two Italian ruscus, one UK-cut eucalyptus.
- Dahlias: 1 each = 3
- Dutch spray roses: 3 each = 6
- Kenyan roses: 4 each = 8
- Italian ruscus: 3 each = 6
- UK eucalyptus: 1 = 1
Total 24, over ten stems, is an average of 2.4.
Now test a swap. Trade the two Kenyan roses for two more British dahlias, if the grower has them, and the average falls to 1.9. Swap the Italian ruscus for British foliage and it drops again to about 1.7. That is the whole point of the exercise: the score tells you where to look, not what to feel guilty about.
Recording it at the bench
Keep it dead simple — a clipboard, or a note on the bench tablet. Seven columns is plenty:
- Date and recipe name
- Stem, variety and origin
- Transport (air, sea, road, local)
- Season band (in, out, stored)
- Score, one to five
- Mechanic used, and whether it is reusable
- Notes and a possible swap
Fill it in for your three best-selling recipes, once. Compare the totals. Then do it again in February, because the answer changes with the calendar. A December score and a June score are different animals, and pretending otherwise is where greenwash creeps in.
Talking about it without overclaiming
Three rules that keep you out of trouble.
Say 'lower-impact choice', never 'carbon neutral'. Say what you compared it to. And say plainly what you don't know — freight data is patchy, growing method is often a mystery, and you are ranking, not measuring.
In practice that sounds like: 'We score our recipes stem by stem — origin, season, transport and mechanics. This bouquet comes out at 2.4 on our own five-point scale; last winter's version was 3.6. We swapped flown roses for British dahlias and reused the vessels.' Specific, honest, and far more convincing than a badge on the cellophane.
Where the wins actually are
For most UK shops, in order of impact: cut air freight, move with the season, lean on British foliage (it scores well and often costs less than imported alternatives), and reuse your mechanics. Ribbon and wrap deserve attention, but they are rounding errors next to a flown rose in January.
Start with one recipe. Score it. Then score the version you would rather sell.
