Today marks the 50th Anniversary of Earth Day.

Every year the Earth Day Network, as organisers of the original Earth Day, selects an environmental priority to engage the global public.

The enormous challenges – but also the vast opportunities – of acting on climate change have distinguished the issue as the most pressing topic for the 50th anniversary year. At the end of 2020, nations will be expected to increase their national commitments to the 2015 Paris Agreement on climate change, so the time is now for citizens to call for greater global ambition to tackle our climate crisis.

Climate change represents the biggest challenge to the future of humanity and the life-support systems that make our world habitable. Unless every country in the world steps up – and steps up with urgency and ambition – we are consigning current and future generations to a dangerous future.

Earth Day 2020 will be far more than a day. It must be a historic moment when citizens of the world rise up in a united call for the creativity, innovation, ambition, and bravery that we need to meet our climate crisis and seize the enormous opportunities of a zero-carbon future.

Organised by the Earth Day Network, Earth Day 2020's campaign was focused on 'Climate Action'.
