Innovative devices were fitted to a fleet of Tiger delivery trucks, capturing 95% of their pollution before it reached the air. The harvested carbon was purified and turned into safe, high-quality ink. Air–Ink pens and markers were sent to street artists and activists around the world. They used them to reclaim the streets, using prominent roadside billboards in major cities around the world, buildings, posters and petitions. The fleet of Tiger delivery trucks also served as mobile posters for the campaign as they harvested the pollution live on the streets of London.

Air pollution already kills 3.3 million people a year and that number could double by 2050. It’s a global problem affecting major cities on every continent, but Asia is by far the worst hit with Asian cities massively over-represented in WHO most polluted cities lists. Tiger beer is directly impacted. It is Asia’s number 1 beer, and is widely known as “the beer of the streets” in light of its long association with street level art and culture and dependence on street-food tables, street bars or other outdoor venues (62% sales).
