C40 & Advertising Partners Launch Global Pro Bono Digital Ad Campaign to Showcase City Leadership

Today, C40 launched #CitiesAreKey, a new global social and digital ad campaign designed to amplify the leadership role of cities in the lead-up to the international COP21 climate negotiations in Paris in December. The campaign, announced via continuous ads on the iconic ‘Grand Screen’ digital billboard throughout the weeklong Cannes Lions International Festival of Creativity, will capitalize on key moments on the Road to Paris to spread global awareness about cities’ potential to help deliver emissions reductions necessary by 2020 to limit global warming to two degrees Celsius.

Sponsoring and creative partners on the effort include Clear Channel Outdoor (CCO)International Advertising Association (IAA) and DM9 Jayme SyFu (DM9).

“As mayors, our primary focus is on making our cities the most sustainable, prosperous places for our citizens to live and work, which doesn’t leave much time to broadcast to the world what we’re able to achieve,” said C40 Chair and Rio de Janeiro Mayor Eduardo Paes. “On behalf of all C40 mayors, I want to offer deep gratitude to CCO, IAA and DM9 for making this invaluable campaign possible. We know cities are key – now the world will, too.”

In addition to the #CitiesAreKey campaign launch on the Grand Screen at Cannes Lion, the campaign will also include videos highlighting C40 city solutions broadcast to hundreds of thousands of pedestrians and vehicles from a digital billboard in New York City’s iconic Times Square during Climate Week NYC.
