Earth Hour 2018

Earth Hour, WWF’s landmark movement, is once again set to bring millions of people around the world together to show their commitment to the planet.

As we face the dual challenge of climate change and plummeting biodiversity, the world’s largest grassroots movement for the environment aims to mobilise individuals, businesses and governments to be a part of the conversation and solutions needed to build a healthy, sustainable future – and planet – for all.

Lights out

Earth Hour started as a symbolic lights-out event in Sydney in 2007, and is now celebrated in more than 180 countries and territories as a global moment of solidarity for the planet.

Online, #EarthHour and related terms generated over 3.5 billion impressions in the run up to Earth Hour 2017, trending in at least 30 countries worldwide on the night.

The movement has been a game-changer for popularising climate and environmental action across the globe. As global biodiversity declines at an unprecedented rate, Earth Hour will focus its efforts on galvanising mainstream support for action on biodiversity and Nature.

Inspiring action

In the past decade, Earth Hour has inspired millions to support and participate in critical climate and conservation projects led by WWF and many others, helping drive climate policy, awareness and action.

Among its highlights, the movement has helped in the creation of a 3.4 million hectare marine-protected area in Argentina, a 2,700-hectare Earth Hour forest in Uganda and helped pass new legislation for the protection of seas and forests in Russia.

‘Biodiversity and Nature underpin our lives, our economies, our health, our wellbeing, our happiness. It is the foundation of our living planet. Today, as we push the planet and its natural systems to the edge, Earth Hour is our chance to use our power, as individuals and as a collective, to demand and take action to protect this web of life in return for all it gives us. For the benefit of all life on Earth and of our own future.’

Earth Hour 2018

In 2018, WWF and Earth Hour teams around the world will be using the movement to highlight the environmental issues most relevant in their country or region.

In Colombia, people will call for the country to commit to zero deforestation by 2020. French Polynesia is expected to move to protect 5m square kilometres of its seas to preserve ocean ecosystems. In Guatemala, citizens will raise their voice on the importance of freshwater conservation and in India, people will pledge to shift toward sustainable lifestyles. In Nepal, WWF will mobilise public support for a clean, renewable energy future for all.
