Cannes Lions.
Cannes Lions will enforce new integrity standards for entries in the Festival of Creativity from 2026, marking a significant shift in the governance of global creative awards.
The changes follow controversy at the 2025 festival, where winning work was withdrawn due to AI-controversy, greenwashing claims and unverified campaign statistics.
“The industry landscape is changing at lightning speed,” said Lions CEO Simon Cook.
“And, in common with the rest of the industry, Cannes Lions is adapting at pace to meet this.”
Brazil’s DM9, owned by DDB, returned its Creative Data Grand Prix and 11 other lions for Whirpool’s Consul Brand ‘Efficient Way to Pay’ after admitting to using AI-altered footage, including clips from CNN Brasil.
Outdoor Silver Lion-winning campaign ‘Nature Shapes Britannia’ by India’s Britannia and Talented was criticised by former Cannes Lions juror Polina Zabrodskaya for greenwashing sustainability claims.
Others, including LePub São Paulo’s Bronze Lion–winning Followers Store, has had claims of unverifiable campaign results.
Entries from 2026 will now require approval from both the entrant company and a senior brand marketer to verify that submissions are factually accurate and responsibly sourced.
A new hybrid verification system, combining human and AI-led analysis, will be introduced to fact-check claims.
Juries will also have access to independent data experts during judging to validate impact and effectiveness.
At the same time, Cannes Lions will launch an AI Integrity Handbook, establishing guidelines for transparency, disclosure and ethical boundaries in creative submissions.
The handbook draws on global frameworks such as the OECD AI Principles and UNESCO’s AI Ethics Recommendation.
Cook said the festival has a responsibility to safeguard the value of creativity as a business driver.
“At the heart of the Lions is creativity that drives growth."
"These renewed standards reflect our responsibility to both provide a platform for, protect the value of creativity and reinforce that creative excellence should be synonymous with creative integrity."
Lion-winning brands achieved a 2.7% rise in profitability and a 4.7% increase in market capitalisation within a year of their award – significantly outperforming market averages, according to Interbrand research presented at Cannes 2025.
Entries found to have included false or misleading information risk being disqualified at any stage – even post-award – with possible bans of up to three years for deliberate misconduct. Jury eligibility may also be revoked.
These decisions will be reviewed by a newly formed Integrity Council made up of legal and ethical experts.
To ensure transparency, Cannes Lions will publish an annual integrity audit highlighting issues raised and actions taken.
“Creativity is only valuable if it’s credible,” said Cook.
“And credibility must be earned, not assumed.
"These timely changes mark the beginning of a new era for us all – not just for Cannes Lions, but for the future state of global creative marketing.”
