World Environment Day History

WED embraces smaller and less-developed nations while tackling even bigger topics: from sustainable consumption to the illegal trade in wildlife. The annual day of action that began more than 40 years earlier goes viral on social media.

2022: World Environment Day

The theme for 2022 was “Only One Earth” and was hosted by Sweden.


Every World Environment Day is hosted by a different country, in which official celebrations take place, and this year’s host is Pakistan.

The Government of Pakistan plans to expand and restore the country’s forests through a ‘10 Billion Tree Tsunami‘ spread over five years. The campaign includes restoring mangroves and forests, as well as planting trees in urban settings, including schools, colleges, public parks and green belts.

Through the 10 Billion Tree Tsunami, Pakistan is contributing to the Bonn Challenge, a global effort linked to the UN Decade on Ecosystem Restoration. Under the challenge, countries are pledging to bring 350 million hectares of the world’s deforested and degraded land into restoration by 2030.

2020: World Environment Day

The theme for 2020 is “Celebrate Biodiversity“, and will be hosted in Colombia in partnership with Germany.

Colombia is one of the largest “Megadiverse” nations in the world to hold 10% of the planet’s biodiversity. Since it is part of the Amazon rainforest, Colombia ranks first in bird and orchid species diversity and second in plants, butterflies, freshwater fish, and amphibians.


The theme for 2019 is “Beat Air pollution“. The host nation is China. This theme was chosen as it has been killing about 7 million people annually.

In Reunion Island, Miss Earth 2018 Nguyễn Phương Khánh from Vietnam delivered her speech during the World Environment Day with the theme “How to fight global warming“.


India hosted the 45th celebration of WED under the theme “Beat Plastic Pollution“. Over 6,000 people gathered at Versova Beach in Mumbai to join UN Environment Champion of the Earth, Afroz Shah, in a beach clean-up, where they collected over 90,000 kg of plastic. The Indian government made a bold commitment to ban all single-use plastics – which makes up 70 per cent of marine litter – by 2022 and European Union lawmakers agreed on a ban by 2025.

2017: World Environment Day

I’m with nature” is the theme of World Environment Day 2017, which inspires more than 1,800 events, from tree-planting in Mumbai to ivory burning in Angola to a running race through Brazil‘s Iguaçu National Park. In host country Canada, Prime Minister Justin Trudeau joins UN Environment’s Erik Solheim to connect with nature by paddling kayaks along the Niagara River.


The day is a springboard for #WildforLife, UN Environment’s biggest-ever digital campaign and a major push to counter international wildlife crime. Host country Angola promises to curb the trading of elephant ivory. China, a key destination for illegal wildlife products, subsequently pledges to close down its domestic ivory market.


World Environment Day goes viral: hosted by Milan, Italy under the theme “Seven Billion People. One Planet. Consume with Care“, it is the most popular subject on Twitter in more than 20 countries. More than 500 videos about World Environment Day are posted on YouTube.


The theme “Raise Your Voice Not the Sea Level!” builds awareness of the dangers facing island nations from climate change. The next year, small island states secure agreement at the Paris climate talks to pursue the ambitious goal of limiting the increase in average global temperature to 1.5oC.


Hosted by Mongolia, this year’s theme is Think.Eat.Save. The campaign addresses the huge annual waste and loss of food and aims to empower people to make informed choices to reduce the ecological impact of food production.

What You Can Do:

This year’s WED provides an opportunity for each of us to combat air pollution around the world. And you don’t have to wait until 5 June to act.

There are so many things that we can do: from cycling or walking to work and back, to recycling non-organic trash, to pressuring local authorities to improve green spaces in our cities. Here are some other ideas:

  • Turn off lights and electronics not in use.
  • Check efficiency ratings for home heating systems and cookstoves to choose models that save money and protect health.
  • Never burn trash, as this contributes directly to air pollution.

What else can we do to tackle this problem? Share your ideas on social media using the hashtag #worldenvironmentday.
