World Environment Day

In 1972, the UN General Assembly designated 5 June as World Environment Day (WED). The first celebration, under the slogan “Only One Earth” took place in 1973. In the following years, WED has developed as a platform to raise awareness on the problems facing our environment such as air pollution, plastic pollution, illegal wildlife trade, sustainable consumption, sea-level increase, and food security, among others. Furthermore, WED helps drive change in consumption patterns and in national and international environmental policy.

2020: Biodiversity and Time for Nature

The theme for World Environment Day 2020 is “Biodiversity” with the slogan “Time for Nature” — a call to action to combat the accelerating species loss and degradation of the natural world. One million plant and animal species risk extinction, largely due to human activities. Recent events, from bushfires in Brazil, the United States and Australia to locust infestations across East Africa – and now, a global disease pandemic – demonstrate the interdependence of humans and the webs of life in which they exist. Nature is sending us a message.

Colombia: The Host Country

Every World Environment Day is hosted by a different country, in which official celebrations take place. This year’s host is Colombia in partnership with Germany. World Environment Day urges us to rethink how our economic systems have evolved and the impact they have on the environment. These are issues the world cannot lose sight of even as we tackle the coronavirus pandemic and the ongoing climate crisis. Colombia has one of the highest diversity of species in the world, boasting among many others, 3500 types of orchids and 19 per cent of the world’s bird types. The government has made biodiversity preservation a national priority.

2020: Celebrations in Geneva

Each year, the Geneva Environment Network partners with the various environmental organizations and government authorities in Geneva and its surrounding region to celebrate World Environment Day. Roundtables, briefings, exhibitions, nature outings and other events are organized throughout the first week of June.

The emergence and re-emergence of zoonotic origin diseases are closely interlinked with the health of ecosystems. The risk of disease emergence and amplification increases with the intensification of human activities surrounding and encroaching into natural habitats, enabling pathogens in wildlife reservoirs to spill over to livestock and humans. Transformative action on protecting and restoring nature and the biodiversity of our planet is urgently needed, as we have much to gain from working with nature.

“Beat Air Pollution” — A call for action to combat one of the greatest environmental emerging challenges of our time. Often you can’t even see it, but air pollution is everywhere and affects your health from head to toe. With every breath, you are probably sucking in tiny particles that attack your lungs, heart and brain.


“Beat Plastic Pollution” — The aim was for people to strive and change their everyday lives to reduce the heavy burden of plastic pollution. People should be free from the over-reliance on single-use or disposables, as they have severe environmental consequences. In addition, we should liberate our natural places, our wildlife and our own health from plastics.


“Connecting People to Nature” — In the city and on land, from the poles to the equator, it encourages worldwide awareness for the protection of our environment.


“Go Wild for Life” — The campaign aimed to reduce and prevent the illegal trade in wildlife.


“Seven Billion Dreams. One Planet. Consume with Care.” — This was the slogan picked through a voting process on social media.


“International Year of Small Islands Developing States (SIDS)” — The UN General Assembly aimed to highlight the development challenges and successes of the SIDS, focusing on global warming and its impact on ocean levels. The slogan was “Raise your voice not the sea level” for this year.


“Think. Eat. Save.” — The campaign addressed the huge annual food waste and loss. With the amount added together, it would release a large quantity of food as well as reduce carbon footprint. The theme also aimed to empower people to make informed choices about the food they eat so as to reduce the overall ecological impact due to the worldwide production of food.


“The Green Economy” — The campaign invited people to examine their activities and lifestyle and see how the concept of a “Green Economy” fits into it.


“Forests: Nature at Your Service.” — Activities were organized with clean-ups, concerts, exhibits, film festivals, community events, tree plantings and much more.
