They are committed to raising awareness, promoting sustainability practices and advocating for policies that address climate change.
The web page https://www.una-climateandoceans.org/climate-action-platform offers a wealth of information and down to earth climate action advice at global and local levels.

It also contains a lot of links to useful websites covering many different categories including Renewable energy (with links and advice), Sustainability, Carbon Removal, Local Action, Travel and Transport, Food Choices etc.
