@misc{Banhardt_Christoph_Uncertainties, author={Banhardt, Christoph and Hartenstein, Felix}, howpublished={online}, publisher={Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego}, language={eng}, abstract={Carbon accounting has become a valuable tool for expressing the fossil energy demand of products, organizational entities, or entire countries. About a decade ago, cities also began accounting their carbon emissions. The first major city to do so was London in 2009, stating a carbon footprint of 4.84 tCO2eq/(Lear*capita) for 2008. Nowadays, multiple rankings compare the carbon emissions of cities.}, abstract={For example, the Urban Land Magazine lists Sao Paulo as the city with the world?s lowest carbon emissions (1.4 CO2eq/(year*capita)). Such listings typically present the depicted emission values as scientifically indisputable numbers. However, a closer look at the applied methodology frequently reveals a wide range of implicit, often undisclosed assumptions at the foundation of the calculations.}, abstract={This paper analyses the uncertainties of carbon accounting on the city scale, using the example of the Red Sea resort town of El Gouna. The estimated value of El Gouna`s carbon footprint for the year 2014 is 14.3 tCO2eq/(year*capita). Third Scope emissions constitute the majority of El Gouna?s carbon footprint. Varying their underlying assumptions only slightly can lead to alterations of the results of more than 50%, questioning the robustness of the findings. To increase the robustness and the comparability of carbon accounting across cities, this paper suggests emphasizing Scope 1 and Scope 2 emissions, while limiting the role of Scope 3 emissions.}, type={artykuł}, title={Uncertainties of estimating a town`s carbon footprint - case study El Gouna, Egipt}, keywords={carbon accounting, carbon emission, carbon footprint, city emissions, dwutlenek węgla, emisja dwutlenku węgla, zanieczyszczenie miasta}, }
