Tracking CO₂ emissions! To hit climate targets, we must measure, not just calculate. Projects in Zurich & Munich use urban sensor networks to capture city data.
Used: our DL-LP8P buff.ly/k54HFl3 and other sensors developed with #Empa.

📊 A 2023–2024 survey from the #ICOSCities project shows that residents of Paris and Munich have more faith in local authorities than in national governments when it comes to climate action.

#ICOSCities project is featured in Nature as part of a story on the smart sensors. 🏙️
The article features Lukas Emmenegger talking about ICOS Cities’ groundbreaking ‘top-down’ monitoring of emissions in Zurich, Paris and Munich.

Great to see our devices DL-LP8P and custom higher accuracy instruments in the field for #ICOSCities @icos-ri.eu @empa-materials.bsky.social
To complement Paris’s emission inventories, #ICOSCities researchers from LSCE deployed a dense network of greenhouse gas concentration and flux sensors at varying heights across central Paris, creating the largest and longest deployment of CO₂ sensors over any city.

As part of the #ICOSCities project, Zurich now has 60 atmospheric sensors measuring real-time CO₂ levels across the city. For the first time, authorities can compare live atmospheric data with the traditional emissions inventory.

🔎 While the data validates Paris’s emission reductions, further efforts are needed to reach carbon neutrality by 2050. #ICOSCities researchers say the current plan can meet 2030 targets, but falls short of the 2050 #netzero goal.

For the first time, independent monitoring data from #ICOSCities confirms that GHG emissions in Paris have decreased by 25% in the last decade, aligning almost perfectly with the 26% CO₂ reduction reported by Airparif (2015–2022).

How can live action role-play be a tool in developing data services for city policymakers?
Organised by the Horizon Europe project #ICOSCities, participants' game roles explored how urban climate data can be used in policymaking.

New essential guidance for #cities! 🏙️ The new Urban Emission Observation & Monitoring Guidelines are here. With 70% of global #GHGs from urban areas, cities need robust tools to measure emissions & track reduction progress. Q&A and guidelines: h1.nu/1h4pQ #ICOSCities
Productive time at #ICOSCities event Science meets City: Munich! 🇩🇪We connected with city reps on #urban #GHG monitoring & #climate action, and also brought partners together for our annual meeting to review key results. 👀Check out all the photos: shorturl.at/LXOZ8
Kicking off now in #Munich: the #ICOSCities final annual project meeting! 🙌 🇩🇪 🌍 We're thrilled to host over 80 participants from all over Europe for two days focused on cutting-edge #urban #greenhouse gas monitoring and essential #climate action services for cities. 🎯
Happy day 5 of #EGU25! If you are interested in #urban #ghg observations, join the Urban Air Quality and Greenhouse Gases session in E2 today. We have a series of presentations from the #ICOSCities project there this afternoon, more details on www.icos-cp.eu/egu25
Ke Che from @lsce-ipsl.bsky.social presented their work on optimising CO2 emission estimates in Paris through monitoring, part of the #ICOSCities project. Lots of good questions and engagement in the room, you can learn more about the ICOS Cities project on www.icos-cp.eu/projects/ico...
#EGU25
Day 2 of the #ICOSCities & @wmo-global.bsky.social #UrbanGHGsummit has been another insightful and engaging day! The focus remained sharp on innovative urban greenhouse gas monitoring techniques.
Join us tomorrow for Day 3, link to livestream on our website: www.icos-cp.eu/news-and-eve...
A new teaching module, developed by Astrid Hügli in #ICOSCities project, helps teachers to address climate change in a fun and experimental way with teens. Available soon! The module also includes climatefresk.org discussion cards.

At the #UrbanGHGsummit in Geneva, greenhouse gas emission experts from #ICOSCities project are joining forces to curb urban emissions. Leena Järvi, Olivier Laurent, and Andreas Christen are presenting the latest findings from the project. @helsinki.fi @envmet.bsky.social @lsce-ipsl.bsky.social
Jia Chen from Technical University of Munich @tum.de presenting their work on monitoring greenhouse gas emissions with ground-based remote sensing. Focusing on lessons learned from MUCCnet - a network of 5 stations within and around Munich - part of the #ICOSCities project.
#UrbanGHGsummit
Andreas Christen @envmet.bsky.social from University of Freiburg presenting an overview of the principles, applications and limitations of eddy covariance flux measurements in cities. This is part of the Urban Good Practice Guidelines and will be discussed more this week

Kicking off the afternoon session at the Urban Greenhouse Gas Summit by @wmo-global.bsky.social and @icos-ri.eu is Lukas Emmenegger (EMPA), #ICOSCities Zurich Scientific lead.
Impressive work towards observation-based CO2 emission estimates for the city of Zürich.
#UrbanGHGsummit
At the #ICOSCities & @wmo-global.bsky.social #UrbanGHGsummit in Geneva, we invited participants to share their messages to cities about urban greenhouse gas monitoring and the use of climate data in decision-making. Here are some of their messages! 🏙️🗣️
A slide summarizing the content of the Urban inventory guideline developed in the ICOS Cities project
In the Urban Greenhouse Gas Summit by @wmo-global.bsky.social & @icos-ri.eu, Ingrid Super from TNO presents a guideline & tools on how downscaling from emissions databases can be used to get a good estimate of a city emission inventory. Check icos-cities.eu for more!
