“Climate Budget”: how Oslo uses data to become a Green City
In 2017, Oslo Municipality adopted a “climate budget”, operating as a financial budget. Each year, it imposes on itself maximum volumes of CO2 emissions, measured on a daily basis through concrete indicators, accessible in real time. The approach now applies to the private sector as well. This is enough to justify the title of “Green Capital”, awarded by the European Commission to the city in 2019.
