5.4.2 BUILDINGS in detail In order to reduce carbon emissions from buildings, cities have two distinct options. They can either focus on reducing the energy used in buildings through energy demand reduction measures (such as installing energy efficient lighting), or they can deliver clean energy through building-integrated renewable energy generation (e.g. installing photovoltaic panels).

% of actions Yes, this action is being taken Based on responses from 53 cities.
No, this action is not being taken
•
This figure shows the proportion of responses where C40 cities are taking a buildings-related action across all potential responses.
•
Regardless of building type, C40 cities report pursuing more than 50% of available buildings action in the survey.
•
Cities indicate that they are focusing energy efficiency and demand reduction over on-site energy generation. In fact, cities report approximately 967 emissions reduction actions to 701 energy generation actions. This is slightly more than 5 energy demand reduction actions per reporting city.
