Earth Hour is celebrated every year on the last Saturday of March.

So this year corresponds to March 25.

This is considered the most widespread and important environmental awareness campaign worldwide, to reflect on the need to act decisively in the face of climate change and counteract its impact on nature and the planet.

What is Earth Hour?

Earth Hour was launched in 2007 by the

World Wide Fund for Nature (WWF) and the

Leo Burnett

advertising agency

, with the aim of drawing international attention to the adverse effects and impact of climate change.

It is a global movement that calls to care for the health of our planet and its inhabitants.

Earth Hour is a worldwide initiative through which it aims

to raise awareness of the need to take urgent measures against climate change

caused by human activity.

It consists of a voluntary electrical blackout, in which people and companies are asked to turn off lights and non-essential electrical appliances for one hour, from 8:30 p.m. to 9:30 p.m.

This promotes energy savings, the reduction of polluting emissions and the reduction of light pollution.

The first Earth Hour was held in Sydney (Australia) on March 31, 2007, between 7:30 p.m. and 8:30 p.m.

The lights of monuments and buildings were turned off for an hour, as a symbolic gesture in rejection of the problem of climate change.

San Francisco also joined with the action called

Lights Out

.

What started in Sydney has grown into a global movement, reaching thousands of cities in 188 countries and territories.

What is sought with the blackout of an hour?

Currently, the Earth Hour movement

promotes direct actions to counteract the impact of climate change

, as well as the adoption of sustainable lifestyles that take into account the conservation of forests, seas and natural resources.

The promoters of Earth Hour assure that climate change is already a proven fact and that because of this the consequences, if something is not done, can be devastating.

The simple fact of turning off the lights for an hour will not avoid any climatic consequences, but it does seek to raise awareness among people so that their actions are more responsible with the environment.

Motto 2023: Turn off the light.

Take a tour of the planet

Every year a theme is chosen to develop in Earth Hour and this year it is a very sporty and team goal.

In the year 2023, apart from symbolically turning off the light on March 25 from 8:30 p.m. to 9:30 p.m., a new challenge is proposed that can be started right now.

The

#KMPorElPlaneta #VueltaAlPlaneta

initiative invites you to participate in a challenge that uses the values ​​of sport, such as effort and teamwork, to show that adding small actions we can overcome the climate crisis, which is the most important race of our lives .

Motto for the year 2022 "A Moment of Reflection"

For the year 2022 the motto was

A Moment of Reflection

.

2022 was a decisive year, in which the alliance of governments, organizations and civil society was required to stop and reverse the loss of nature by the year 2030.

This also contemplates compliance with all the Sustainable Development Goals set out in the 2030 Agenda.

After the Earth Hour 2022 edition, the meeting of world leaders took place at COP15 of the United Nations Convention on Biological Diversity.

Efforts will be joined to generate a global action plan for nature for the next decade.
