Environmental conventions

One of the ways that WMO contributes to sustainable development is through international environmental governance as enshrined in various United Nations and other international conventions.

The data collected from WMO’s networks of ground- and space-based systems, combined with the application of improved scientific knowledge and computing technology, provide the information products, services and assessments necessary for the formulation of relevant policy decisions on which international environmental governance may build.

WMO, with relevant partners, co-sponsors several programmes for scientific research and assessments to support intergovernmental legal agreements on major global environmental concerns such as ozone-layer depletion, climate change, desertification and biodiversity. WMO also coordinates the observing systems which provide the necessary data to assess atmospheric-ocean processes and interactions, such as El Niño/La Niña, and water-resources availability.
