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 2035.5
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 2050.5
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.1,4

19 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement goal. A wide assessment database of these new scenarios is not yet available; thus, we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches.
