Abstract

A comparative analysis of the original methods of modeling urban greenhouse gas emissions caused by communal and transport sectors was carried out. These methods provide information at the level of urban-planning areas limited by the elements of the transport network and characterized by relatively similar buildings. These methods make possible to calculate greenhouse gas emissions from sources of the public sector, such as electricity and heat generation, gas burning for domestic needs. Calculation of emissions from sources of the transport sector includes differentiation by individual street segments. The described methods correspond to different accuracy levels including: the transition from aggregated values to the amount of emissions of individual areas of the city (downscaling); calculations using energy standards; calculations using actual energy consumption data. The considered methods have been tested on the example of the city of Nur-Sultan, that is one of the largest in the Republic of Kazakhstan. The calculation results are close to the actual values of Nur-Sultan's emission. The advantages and disadvantages of the considered methods are described. The factors leading to inaccurate results are considered. It was confirmed that the considered methods can be used for planning climate policy measures, since they allow to identify areas of the city and fields of activity that make the maximum contribution to the formation of greenhouse gas emissions. The considered methods are significant of for the cities of the former Soviet Union, which are characterized by the absence of developed systems for monitoring greenhouse gas emissions, is described, and it becomes necessary to calculate greenhouse gas emissions using indirect sources.
