Project Everyone is the brainchild of Richard Curtis, the filmmaker and founder of Comic Relief. MacKenzie, a chief marketing officer at initiative Aviva, has taken a two year secondment to work on the project.
Its aim is to promote the simple but ambitious global goals the UN is set to launch in September 2015, to seven billion people in seven days.
Project Everyone is also working with Global Citizen and the Bill and Melinda Gates Foundation.
MacKenzie was speaking at Media360 last week, where the flame-haired marketing leader joked about her similarities with Rebekah Brookes. Being older than the former News International chief, MacKenzie claimed she "had the look first".
She told media owners they were needed to help make Project Everyone’s goals famous.
She said: "This is going to be enormous. I would love to think the global goals could turn up on Innocent bottles, on Jimmy Choo boxes.
"In media terms, of course, we would love some inventory, or shared space or attributed space, or just brilliant ideas brilliantly executed."
Project Everyone's activity to date includes a seven-day pop-up radio station, with unique content curated by influencers from around the world and distributed by the world’s largest broadcasters.
It will work with the world’s top websites including Google, YouTube, Huffington Post, Yahoo, Facebook, LinkedIn and Wikipedia, to communicate to speakers of more than 200 languages.
It will also feature the largest collaborative education project the world has ever seen in partnership with Unicef, Times Education Supplement, Sir Ken Robinson and Pearson.
And in partnership with Global Citizen and their Festival, Project Everyone is launching the global goals in a one-hour TV spectacle, live-streamed on YouTube and shown by broadcasters across the world.
SAWA are giving access to their cinema network around the world, giving £15m of inventory and screening a bespoke advert written by Sir John Hegarty and animated by Aardman.
