Page 20 - Methodology to assess Net Zero progress in cities

The city will be mapped according to the performance of the identified key performance indicators
(KPIs) to maturity levels (Table 2). The table below contains an individual column that measures the
ICT performance in the city (digital transformation), based on the ICT implementation efforts and
data availability. The model recognizes the importance of digital transformation to carbon neutrality.

3.2 Carbon Neutrality Progress assessment

Wei et al. (2021) presents the results of their study concerning the identification of the effectiveness
of carbon reduction policies. The study conducted energy-related GHG emission inventories
(by eight urban sectors: residential and institutional buildings; commercial buildings; industrial
buildings (energy use); industrial process and fugitive emissions; on-road transportation (cars,
buses); railways, aviation, and waterways; waste disposal (wastewater treatment, landfills); and other
(agriculture and mining) for 167 globally distributed cities, from 53 countries, with information from
different sectors. The study assessed the progress of historical GHG emission reduction and the
climate targets of global cities in a comparable way.
