This year, the campaign slogan for the 2022 World Environment Day (WED) on 5 June is “Only One Earth” that clearly calls for a global, collective and transformative action to celebrate, protect and restore our planet, because we have #OnlyOneEarth and we must take care of it.


  • World Environment Day on 5 June is the biggest international day for the environment. Led by the United Nations Environment Programme (UNEP) and held annually since 1974, the event has grown to be the largest global platform for environmental outreach, with millions of people from across the world engaging to protect the planet.
  • This year, #WorldEnvironmentDay 2022 is hosted by Sweden that will also host the high level Stockholm+50 international meeting from 2 to 3 June. 2022 is a historic milestone for the global environmental community. It marks the 50th anniversary of the first United Nations Conference on the Human Environment, held in Stockholm in 1972 and widely considered as the first international meeting on the environment. The 1972 Stockholm Conference spurred the formation of environment ministries and agencies around the world and kickstarted a host of new global agreements to collectively protect the environment This put sustainable development on the global agenda and led to the establishment of World Environment Day, with the first one being celebrated in 1974
  • “Only One Earth” is the campaign slogan focused on “Living Sustainably in Harmony with Nature” . There is a circularity in this year’s World Environment Day as 50 years ago the theme of the Stockholm Conference was exaclty the same, “Only One Earth”. The message is as important today as it was then. The slogan does emphasize that planet Earth is still the only liveable planet we have and to push for transformative actions to reset the balance between people and the natural world to create a better future for all.
  • With over 150 countries participating, this UN international day engages governments, businesses, civil society, schools, celebrities, cities and communities, raising awareness and celebrating environmental action.




  • We are using the equivalent of 6 Earths to maintain our current way of life, and ecosystems cannot keep up with our demands.
  • The gap between what we need to spend to adapt and what we are actually spending is widening. Estimated costs of adaptation continue to rise and could reach US$280-500 billion per year by 2050 for developing countries alone.
  • Individuals and civil society must play a key role in raising awareness and urging governments and the private sector to make large-scale changes.




  • Air pollution causes about 7 million premature deaths every year, one in nine of all deaths. Nine out of 10 people breathe unclean air, making it the most significant environmental health risk of our time.
  • Only 57 per cent of countrieshave a legal definition for air pollution. In 2019, 92 per cent of peopleexperienced air pollution in excess of safe World Health Organization guidelines.
  • The most recent SDG monitoring cycle revealed that over 3 billion peopleare at risk because they don’t know enough about the health of surface and groundwater resources.
