They are midway through their 2016 A Head Full of Dreams World Tour, where they performed at Wembley Stadium to sold-out crowds; they were recently the final act at the Glastonbury Festival in England, and, earlier in the year, they headlined the Super Bowl halftime show in California, which featured Beyoncé and Bruno Mars.

Off stage however, there is a lot more to Coldplay than meets the eye. They have long been not only supporters, but leaders of social justice initiatives, causes and campaigns since forming as a band more than 20 years ago.

In 2006 Coldplay threw their support behind Oxfam's Make Trade Fair campaign and the Make Poverty History campaign.

Then, on Andrew Denton's ABC television program Enough Rope, Martin highlighted the role the band wanted to play beyond music. "We always talk about this thing, 'fair trade’" and rather than promote commercial products Coldplay wanted to "advertise something we believe in."

Recently, Martin joined Global Citizen, which is a movement of people who learn and take action on social platforms and play a direct role addressing some of the world’s biggest challenges, such as ending extreme poverty.

He agreed to take on the audacious task to curate their signature event, the Global Citizen Festival, held annually in Central Park, New York, for the next 14 years. The significance of this long-term pledge demonstrates his commitment to the cause.

At Coldplay's A Head Full of Dreams World Tour, concert goers have been greeted by people like myself, representing Global Citizen and have been encouraged to sign their name to the #SheWill campaign, to help bring an action plan for the 63 million girls who do not have access to an education.

This includes, according to UNICEF, an "estimated 31 million girls of primary school age and 32 million girls of lower secondary school age who were out of school in 2013." Over 100,000 people have put their name to the #Shewill campaign to date.

Children, particularly girls, often miss out on an education. Barriers to their education can include financial factors, an inability to access a school because of geographical location or cultural and gender issues, often surrounding early marriage and childbirth.

Not having access to an education makes the injustices and realities of poverty all the more difficult to escape.

At the Girls’ Education Forum in London however, the British government pledged £100m to support programs to allow girls access to universal primary and secondary education by 2030.

This will help programs that support the United Nations’ Sustainable Development Goals, the commitment to end poverty, protect the planet, and ensure prosperity for all.

Two goals that focus on education and gender equality include to 'ensure inclusive and equitable quality education and promote lifelong learning opportunities for all' and to 'achieve gender equality and empower all women and girls'.

The goals above have been developed and large sums of money have been pledged but governments still need to sign on and agree to and commit to an action plan, to see how this could be achieved.

Even with the likes of Coldplay throwing their support behind such causes, there is still a long way to go to gain global gender equality and education for all.
