AI Translation Summary
In Thailand, air pollution is a health emergency, and in Lamphun the PM2.5 is among the worst. Footballers can't shelter indoors — they breathe far dirtier air on the pitch. So Lamphun Warriors F.C. turned their unchanging white jersey into a real-time air-quality alert, wearing six colour-coded kits that matched live PM2.5 levels and made every broadcast a pollution warning.
Cultural Context
PM2.5 refers to fine particulate matter that spikes each dry season across northern Thailand, largely from agricultural burning. Lamphun Warriors and Buriram United are Thai League clubs; staging an unpaid stunt at a marquee match gave the message national reach.

Summary
Air pollution is a national health crisis in Thailand, ranking 9th globally, with illnesses up 116% YoY. In Lamphun, PM2.5 levels are among the highest. While the government advises the public to stay indoors, footballers cannot, inhaling up to 20 times more polluted air. In football, many things change, from coaches to logos. But one thing rarely does: the jersey. For over 14 years, Lamphun Warriors wore their iconic white kit. To make the invisible visible, we turned it into a real-time air quality alert. Players wore six colour-coded jerseys reflecting PM2.5 levels, turning every match into a live pollution warning and driving nationwide awareness.
Strategy
In Thailand, where air pollution has become a national health emergency, the campaign aimed to shift the narrative from abstract statistics to a visible, emotional reality. By focusing on professional footballers, public figures required to perform outdoors despite health warnings, we turned them into living indicators of the crisis. Lamphun Warriors F.C., a Thai League club based in one of the hardest-hit provinces, became the platform for change. The strategy transformed the team’s home jersey into a real-time air quality alert. Each matchday color reflected PM2.5 data from the Air Quality Index, connecting fans emotionally to the invisible threat. Without paid media, we used football’s cultural relevance and social media presence to amplify the message. The campaign positioned football

We launched The Air Pollution Jersey at the season’s most watched match, Lamphun Warriors vs Buriram United. Players wore jerseys that changed color in real time based on PM2.5 levels, turning every on-field moment and broadcast close-up into a live signal of the crisis. The jersey became the message, visible to fans in the stadium and viewers nationwide. Club channels and national team players shared first-hand experiences of playing in polluted air, adding credibility and reach. Two hours before kick-off, Lamphun’s official channels released the line-up with jersey colors reflecting real-time air quality, prompting fans to wear PM2.5 masks.

After the launch, it sparked discussions widely on Thai social media, had 98.3% positive sentiment on 23 million media impressions without any media spending, and was featured on a top morning news program. This took notice from the Thai League and international media. At the same time, the Clean Air Bill passed unanimously and will be effective this year (2025).
