Quadtrees Hub#6

Towards a spatially explicit urban CO2 budget. Urban carbon emissions, dispersion and sequestration in Europe

On May 21st, our sixth Quadtrees Hub will take place. The aim is to share and discuss research in progress. Quadtrees’hubs are open to anyone interested and somehow familiar with some quantitative techniques and willing to progress with these. Please contact Isabelle Pigeron-Piroth for information.

When? 21st May 2021, 2 to 3 pm

Where? via Webex

2-3 pm : Marlène Boura  (University of Luxembourg, DGEO): Towards a spatially explicit urban CO2 budget. Urban carbon emissions, dispersion and sequestration in Europe

Modelling a steady-state urban carbon balance for 802 European cities at a fine spatial resolution.

Anthropogenic CO2 emissions are downscaled spatially (down to 1 ha) and temporally (from annual to daily) based on the sector of activity, the land use category and the location. Sequestration of CO2 is estimated for different types of urban vegetation, following the IPCC guidelines at the same spatial and temporal resolutions.

For one typical day of each month, we simulate 2 steady-state situations for the CO2 molecules dispersion and capture. The absolute carbon balance and the relative carbon capture (as a percentage of effective anthropogenic emissions) are then computed. The data produced can be used to assess the spatial heterogeneity of the carbon balance within a specific urban area. It can also be used to assess how much of its own emissions an urban area can capture.
