Greenpeace is giving green-minded filmmakers, both aspiring and professional ones, an opportunity to contribute to its one of the biggest recent climate campaigns. Earlier this summer, the environmental organization launched an initiative against Volkswagen (which strives to become the most eco-friendly car manufacturer), which is opposing cuts to CO2. Greenpeace is calling attention to the company’s environmental policy and encouraging people to sign a letter to Volkswagen’s officials—the organization released ‘Star Wars’ inspired viral spots, launched a dedicated website, dropped spoof dark banners in big cities across the globe and organized demonstrations by VW stormtroopers in European cities including London, Brussels and Wolfsburg to get more ‘jedi’ to join the Rebellion (so far, there are 312,900 people in). Now, the brand is inviting activists to do something bigger than just signing the Manifesto—on September 17, Greenpeace is kicking off an international film contest, asking entrants “to expose the real VW—the one behind the billboards.”

Kia continues to ‘drive change’ in Canada with the launch of the next round of its campaign, designed to inspire local people to take action and improve their communities by making simple but effective steps. In the line with the ‘Court’ and ‘Garden’ spots, released last year, the car brand has kicked off a new national promotion earlier this summer to highlight Kia’s commitment to social responsibility, find new local heroes and support them. In addition to this, the brand announced August 21 the 1st annual Kia Drive Change Day and has launched a national competition, asking Canadians to submit a project, which can improve their neighborhood area, for a chance to get a $25,000 cash donation to implement the plan.

Levi’s, which is encouraging the whole world to ‘Go Forth’ with its global campaign, now has made a new big step to promote pioneering spirit on all the continents. The brand, which is committed to inspiring younger generation to create positive social, cultural and ecological changes in the world, is presenting its new film, the ‘Levi’s Legacy’ 60-second spot, which is the first international video of the promotion. The spot, which first premiered on the brand’s Facebook page, will be screened at cinemas on Friday and then will be aired on TV later in August, according to the press release.

Coca-Cola has been a muse for a range of other brands and used as a canvas for creative imaginary by celebrated artists and fashion icons. The legendary drink and its red and white style has become the theme of the eighth edition of the Uniqlo’s UT Grand Prix T-shirt design contest. Designs inspired by Coca-Cola are accepted starting August 4 through September 12—the submissions from all around the globe will be judged by a panel of experts in the design industry and be unveiled for online voting. The winners will receive money prizes and get their designs implemented on tees, which will arrive at Uniqlo’s venues worldwide in spring 2012.

Sony Ericsson teamed up with McCann Erickson, Munich to develop a campaign, which is centered on and inspired by the urban environment.

The brand has launched several absolutely stunning vignettes, ‘challenges,’ revolving around using the smartphones in urban environment, and launched the interactive Challenge the City game in a dedicated hub on its official page.
