Unveiling the Climate Action Navigator Part 5 – CO₂ Budget
Thanks to the newest addition to the Climate Action Navigator, it is now possible to calculate the remaining CO₂ budget for several German cities (Berlin, Bonn, Hamburg, Heidelberg, and Karlsruhe) to stay within certain global warming limits (e.g. +1,5°C). The CO₂ Budget assessment tool also tracks if the city is on the right track to…

New paper “Mapping High-Resolution Carbon Emission Spatial Distribution Combined with Carbon Satellite and Multi-Source Data”
This study develops a framework integrating satellite observations with spatial proxy data to produce high-resolution urban carbon emission maps. The method is applied to Urumqi, China, demonstrating accurate and timely estimations compared with traditional inventories. Reducing carbon emissions is a global priority, but conventional inventory methods based on administrative statistics fail to capture fine-scale spatial…

New paper “Mitigating heat stress by reducing solar exposure in pedestrian routing”
Using Heidelberg as a case study, researchers modeled time-dependent solar exposure for the entire pedestrian network by combining high-resolution DEM/DSM building and vegetation data with OpenStreetMap road data. Adapting to heat stress in cities is a major challenge under global warming, as both climate change and the urban heat island effect increase health risks worldwide.…
