What is Chile's pathway to limit global warming to 1.5°C?
Buildings
In 2020, the building sector in Chile was responsible for around 23% of total national energy demand, and more than 7% of total GHG emissions.1

In 2019, electricity used in buildings represented a 34% share of total sectoral energy consumption. This share would need to double by 2030 and reach over 86% by 2050 to be 1.5°C compatible.
The Chilean government has put in place energy efficiency policies and has specific mitigation plans for the sector. According to the targets set in the 2050 Energy Plan, 100% of public and residential buildings in the country should be in line with the “OECD sustainable construction standards” by 2035.2
In addition, all public sector buildings should be highly energy efficient by 2035. By 2050, all new buildings should be highly energy efficient/rated highly energy efficient and have smart energy management control systems in place. All existing buildings must report on their energy consumption by 2050.3
Chile’s energy efficiency law grants an energy efficiency label to buildings that meet a specific energy rating and also mandates all types of buildings, whether public, residential, commercial or office buildings, to be energy rated as part of the permit process.4,5

All values are rounded. Only direct CO₂ emissions are considered (electricity, hydrogen and heat emissions are not considered here; see power sector for emissions from electricity generation). Year of full decarbonisation is based on carbon intenstiy threshold of 5gCO₂/MJ.
