Not on myPhone

M+C Saatchi Group UK and Bauer Media Outdoor have partnered with environmental charity Let’s Do It World to launch ‘Not on myPhone’, a new national campaign encouraging people to delete unwanted photos from their phones and reduce the hidden carbon footprint of digital storage.

Launching ahead of Digital Cleanup Day 2026 this Saturday, the campaign highlights an often-overlooked source of environmental impact: the millions of unnecessary photos stored in the cloud. With 7.4 billion smartphones in use worldwide, storing digital content has a significant environmental cost. In the UK, the average person takes about five digital photos per day - and across the population, this generates over 800,000 tonnes of carbon annually, comparable to flying from London to New York nearly a million times.

The campaign reframes this invisible issue through a simple behavioural prompt: take 30 minutes to clean up your phone. Deleting approximately 100 photos and a couple of videos equates to the CO2 production of a 1km drive by car.

At the heart of the work is the ‘Not on myPhone’ creative concept, which playfully subverts a familiar aesthetic. Instead of showcasing beautiful photography, the campaign features the chaotic reality of people’s camera rolls: blurry pictures, duplicate selfies, screenshots and random receipts that most of us never look at again.

These images were crowdsourced from real people’s camera rolls and transformed into bold, high-impact outdoor posters. By placing these intentionally mundane images on large format digital Out of Home sites across busy urban locations, the campaign draws attention to the everyday digital clutter quietly contributing to carbon emissions. Every image featured has now been deleted and the campaign will delete itself after 48 hours, when the DOOH media is taken down.

The activity also connects with the wider Digital Cleanup Day global campaign led by Let’s Do It World. Since 2020, 175 different countries have taken part and over 1.7 million people have deleted over 16.8 million GB of data, preventing the yearly production of around 3,360 tons of C02.

As part of this year’s initiative, The University of Northampton is running a week-long pilot encouraging students and staff to take practical steps towards digital sustainability, including a dedicated day focused on deleting unwanted photos.

The campaign launches across the UK from 20 March on large-format premium DOOH sites donated by Bauer Media Outdoor in locations including London, Manchester, Leeds, Glasgow and Edinburgh, positioned near major train stations and on busy roads to encourage commuters to delete unwanted photos. Running entirely pro bono, the activity is supported by social content and the wider Let’s Do It World movement, encouraging people to share the message using #NotOnMyPhone. Additional media placements have also been secured in South Africa, Dubai and Brazil through M+C Saatchi’s international network.
