Pizza Hut pays free pizza to people who leave the internet for Earth Hour
A website that only works offline asked UAE and Oman users to disconnect for an hour during Earth Hour; 10,000 took part — Mobile Lynx Grand Prix 2022.
Pizza Hut (Yum! Brands)
What it had to solve
Every year Earth Hour asks people to switch off their lights for an hour, but household lighting is no longer the biggest slice of energy use — data centres and mobile networks consume more. Pizza Hut wanted to take part in a way that mattered to its young, tech-savvy audience, without asking anyone to eat pizza in the dark.
How it works
Earth Hour has asked people to switch off their lights since 2007, but energy use has changed: data centres and mobile networks now consume more power than household lighting, and research showed 77% of Gen Z would simply turn to their phones once the lights went out. Pizza Hut wanted to join Earth Hour in a way that actually saved energy without making its customers eat in the dark.
With M&C Saatchi Dubai it built offlinehour.me, a mobile website that works only when the visitor is offline. Content loaded into the browser cache, code detected when WiFi and data were switched off, and a 60-minute countdown began; reconnecting stopped the clock and prompted users to go back offline. Finish the hour and a free pizza was on its way. The campaign launched in the UAE and Oman on Earth Hour, 27 March 2021.
The numbers showed the idea worked: over 10,000 people logged on during Earth Hour, spent more than 3,200 combined hours offline, and the campaign reached over 7.4 million people. At Dubai Lynx 2022 the work won the Mobile Lynx Grand Prix plus Gold and Silver in Brand Experience and Activation, and it helped Yum! Brands take Advertiser of the Year in 2023 — a purpose campaign that paid for itself in prizes, participation and awards.
Why it lands
- Targeting internet use instead of light switches attacked the energy source that actually dominates today.
- A website that only works offline made the sacrifice the mechanism — no WiFi, no timer, no pizza.
- The free-pizza reward gave a climate ask an immediate personal payoff, driving 10,000 participants.
- The insight about Gen Z's phones turned a passive Earth Hour ritual into an active challenge.
What it did
More than 10,000 people across the Middle East logged on to take the challenge, spending over 3,200 combined hours offline during Earth Hour, and the campaign reached more than 7.4 million people through the site, banners, social media and PR. The idea also won: 'Offline Hour' took the Mobile Lynx Grand Prix at Dubai Lynx 2022, plus a Gold and Silver in Brand Experience and Activation, and helped Yum! Brands become Advertiser of the Year the following year.
What you can take
Reinvent a tired ritual by changing the unit of sacrifice: target the behaviour that creates the real impact today, and make the reward part of the idea.
Since then
Offline Hour became a reference point for purpose-driven campaigns that reinvent a ritual instead of repeating it: it won the Mobile Lynx Grand Prix at Dubai Lynx 2022 along with Gold and Silver in Brand Experience and Activation, and Yum! Brands credited the work as part of the run that made it Dubai Lynx Advertiser of the Year in 2023. The site remained live as a demonstration, and the campaign is regularly cited as a clever way to connect a fast-food brand to climate action.
