Session: Scalable high-resolution bottom-up GHG emission inventories based on open data
7th April 2025, 10:30 (Geneva, Switzerland)
The Urban Greenhouse Gas Conference and Stakeholder Summit is hosted by the WMO Integrated Global Greenhouse Gas Information System (IG3IS) and ICOS Cities Project. The conference will take place from 7th to 9th April in Geneva, Switzerland. It will showcase the latest findings from urban greenhouse gas researchers, that will be presented and discussed.
In collaborative effort, Dr. Sebastián Block, along with other scientist from HeiGIT and Heidelberg University, has developed a novel method that utilises open-source data to generate high-resolution carbon dioxide emission inventories for road traffic and heating.
In order to effectively mitigate climate change, it is essential to have detailed, bottom-up greenhouse-gas (GHG) inventories that go beyond annual national or city-scale inventories. Data with a higher resolution, both spatially (sub-city) and temporally (daily to hourly), offers important advantages. This enhanced data can be used as input for inverse modelling, to measure the impact of interventions such as policy changes or household behaviour on emissions and atmospheric concentration, or to enhance climate action tracing and communication.
The approach is scalable across Germany and adaptable to various contexts and will be demonstrated in Mannheim and Heidelberg. The power of this bottom-up inventory to quantify the impact of policies and interventions on overall emission levels will be showcased during the poster session.
We are looking forward to an insightful session and engaging discussions on the topic.
