Lorde joined the worldwide Global Citizen Live event yesterday, performing ‘Solar Power’ and delivering a strong message on climate change.

The charity gigs, which aim to “unite the world to defend the planet and defeat poverty,” took place in numerous cities across the world during a 24-hour broadcast and livestream yesterday (September 25).

In the New York leg, Coldplay were the headliners, and were joined by Billie Eilish and Finneas to share a touching rendition of ‘Fix You’.

Lorde opened up the NYC leg, performing the title track from her recent third album on a set of stairs.

Ahead of the performance, she addressed the aims of the livestream, saying: “It’s an honour to be today, amplifying Global Citizen’s deeply important messages.

“Environmental system change must come from our biggest businesses and our lawmakers, but the movement has always belonged to the people. May we all continue to ask questions of our world, and remember: the future is solar.”
