Important environment days in 2023

Historically, the United Nations Organization (UN) commemorates certain days, weeks, years and decades to sensitize and educate people about different issues and problems that the world is going through. In general, it is the Member States that propose the dates and the General Assembly approves them through a resolution.

In order to raise awareness and promote action towards environmental protection and sustainability, it is important to observe notable environmental days.

For the year 2023, we have compiled a list of important dates to remember. Some of these days include World Wetlands Day on February 2, Earth Hour on March 25, World Oceans Day on June 8, World Clean Air Day on September 7, and International Day for the Preservation of the Ozone Layer on September 16.

Below we offer you an environmental calendar for 2023 in which you can see, month by month, the main ephemeris and dates of the world days dedicated to specific aspects of the environment. These are dates to reflect on and keep in mind in the new year.

These are the most important dates to take into account in 2023 to remember and act around the protection of the environment.
