Second-Hand September hands FMCG brands a month of concentrated attention on sustainability and most of them spend it on a green graphic. Oxfam started the campaign in 2019 as a challenge to buy second hand for thirty days and it now runs every September as one of the loudest sustainability moments in the UK calendar. Food and drink sit outside the clothing category, which is why marketers assume the moment belongs to somebody else.
That assumption costs them. The shoppers paying attention in September fill a supermarket basket in October.
What Second-Hand September Means for FMCG Brands
Oxfam run the campaign to cut demand for fast fashion and they make the scale of the problem plain: up to 40% of all clothing made globally never sells.
The campaign reaches far beyond wardrobes. It arrives in the same feed, on the same phone, in front of the same person who does the weekly shop.
Why the Second-Hand September Audience Matters to Food and Drink
Deloitte survey UK consumer attitudes to sustainability every year. Their 2024 Sustainable Consumer research, based on a YouGov poll of more than 2,000 UK adults, found 58% of consumers had cut the number of new products they buy over the previous year and 56% had repaired something rather than replacing it.
Both behaviours describe a shopper thinking hard about what they buy and why. The same instinct that sends somebody into a charity shop in September makes them turn your packaging over in the supermarket.
Deloitte also ranked the practices consumers value most. Sustainable packaging and products came first, reducing waste in manufacturing came second and ethical working practices came third.
Every one of those sits inside FMCG territory. Fashion owns the cultural moment while food and drink hold most of the answer’s shoppers say they care about.
The Sustainability Fatigue Nobody Wants to Mention
Here is the case against saying anything at all. The same Deloitte research found 61% of consumers cite a lack of interest in sustainability as a reason for not living more sustainably. For the second year running, a larger share believe their own choices make no difference.
Marketers read that and conclude the audience have stopped listening. The caution is fair. The conclusion misreads what the fatigue attaches to.
Shoppers tire of vague claims rather than of sustainability. Somebody who rolls their eyes at ‘committed to a greener future’ will still read a line telling them the carton carries a third less plastic than it did last year.
What Shoppers Actually Believe
Specifics survive scepticism. Name the material, the supplier, the percentage or the certification and a shopper can check the claim for themselves.
Vagueness invites the greenwashing accusation marketing teams fear. Our guide on how to communicate your sustainability efforts effectively sets out how to hold that line across a campaign.
How to Activate Second-Hand September Without Sounding Hollow
The weakest activation posts a green graphic on 1 September and goes quiet on 1 October. It costs a designer an hour and it earns nothing.
The strongest activation treats the month as one chapter of a story the brand tell all year. Packaging, sourcing, community, transparency. Our roundup of brands doing sustainability right shows what that consistency looks like in practice.
Take Doisy & Dam, the chocolate brand we work with. They hold B Corp certification; they belong to 1% For the Planet and they refuse palm oil. The sustainability claim arrives with evidence attached rather than adjectives.
During the Easter campaign we built around their orangutan conservation partnership, their Facebook reach rose by 2.6K% and engagement across platforms rose by 654%. Influencer activity around World Wildlife Day lifted profile visits by 178.3%. Those are our own campaign figures for one client over one month rather than an industry benchmark.
A values story with proof behind it also travels through the press, which is why storytelling in PR matters more than the size of your media list.
Let Your Customers Carry the Story
A brand telling shoppers it cares reads as marketing. A customer showing them the same thing reads as evidence. That gap explains why UGC in building brand trust outperforms polished brand film during a moment like this one.
Second-Hand September gives you a natural question to put to your community: how do they cut waste at home and what happens to your packaging afterwards? Ask in September, then run what comes back across the rest of the quarter, which is where scaling UGC marketing turns a moment into a campaign.
Measuring Whether Your Sustainability Communications Work
Track the quality of engagement ahead of the volume. Comment sentiment, saves, shares and the profile of the people responding tell you whether you reached the shoppers you wanted.
Then connect the activity to the till. Basket size, repeat purchase rate and share of voice during the campaign window carry more weight in a board meeting than likes. Our guide on measuring the impact of your sustainable initiatives lists the metrics worth the effort.
Internal credibility decides whether you get to do this again next year. Build the case with numbers and the September line survives the next planning round, a discipline that applies across FMCG marketing in 2026.
Frequently Asked Questions
What is Second-Hand September?
Oxfam started Second-Hand September in 2019. The campaign asks people to buy only second-hand items for the month of September and it now reaches a broad UK audience interested in waste, reuse and where their money goes.
Why should FMCG brands care about Second-Hand September?
The campaign puts a large UK audience in a values-led frame of mind for thirty days. Deloitte research shows the practices consumers value most, led by sustainable packaging and products, sit squarely in the hands of food and drink brands.
Do you need to sell second-hand products to take part?
No. Food and drink brands take part by talking about packaging, sourcing, supply chain or waste reduction, with enough detail for a shopper to check what they read.
How do you avoid looking performative in September?
Say something specific and say it in March as well. One number a shopper can verify beats a paragraph of ambition. Consistency across the year removes the suspicion that the message exists only for the moment.
What should an FMCG brand avoid saying during Second-Hand September?
Avoid any claim you cannot evidence, any target with no date attached and any language that borrows credit from the Oxfam campaign without contributing to it. Shoppers notice the difference and so do journalists.
Second-Hand September rewards the FMCG brands who turn up with proof and exposes the ones who turn up with a graphic. If your packaging, sourcing or waste story has never left the annual report, September is the month a shopper is most likely to read it.
