Late last year, the @WMO #GAW programme published new guidelines for measuring carbon dioxide, methane and nitrous oxide.
Experiences in setting up the ICOS network and Atmosphere station specifications fed into the final guidelines.

With around 70% of global #GHGs originating from urban areas, cities need robust tools to measure emissions and track reduction progress. The Urban Emission Observation & Monitoring Guidelines are vital in these efforts.

Valencia shows why #climatechange is no longer abstract for cities. Record 44.5°C heat, droughts, and floods have become part of recent reality. At the same time, the city has been working on climate mitigation and is stepping up its adaptation efforts.
