India's leading global ambassadors comprising A-list actors, actresses, renowned directors, award-winning authors, dignitaries and esteemed public figures came together in an unprecedented show of unity on January 15, 2015 to show their support via Twitter and Facebook for the launch of the historic action/2015 campaign. The campaign, billed as one of the biggest global outreach initiatives in history to address world-changing issues of climate change, poverty and inequality, saw a massive outpouring of solidarity from celebrities such as actor Akshay Kumar, who was the first major celebrity to tweet his support for the campaign reaching over 7.2 million Twitter followers and over 14 million users on Facebook. He was joined by compatriots Sonam Kapoor, Malaika Arora-Khan, Pulkit Samrat, Kiara Advani, Mohit Marwah author Chetan Bhagat, producers Ashvini Yardi (Grazing Goat Pictures) and Ritesh Sidhwani (Excel Entertainment), TV personalities Gautam Rode, sport stars Yuvraj Singh and Vijendra Singh to name some of the growing list of supporters.

The action/2015 campaign will garner further support on January 15, 2015, when an open letter, signed by such renowned activists as Indian actor Aamir Khan, will be sent to Indian Prime Minister Narendra Modi to encourage further action by India to address such critical issues as poverty, climate change and equality. Other major names to sign the open letter include Queen Rania Al Abdullah, U2 frontman Bono, Hollywood actors Ben Affleck, Matt Damon, Hugh Jackman, philanthropists Bill and Melinda Gates, UK-Sudanese entrepreneur Mo Ibrahim, singer Shakira and 2014 Nobel Peace Prize Laureate Malala Yousafzai among many others.

They issue a stark warning; that while leaders have a historic chance in 2015 to make progress on some of the greatest challenges of our time at two critically important summits, currently too few leaders are playing the leadership roles needed. They set out their fear that if this does not change, leaders could be "sleepwalking the world towards one of the greatest failures of recent history." India, although a country emerging as a powerful and revolutionary force on the world stage, still worryingly accounts for one-third of the world's poor.
