What is Ecuador's pathway to limit global warming to 1.5°C?
Buildings
The emissions from the buildings sector more than doubled in Ecuador between 1990 and 2019. The sector relies mainly on liquid fossil fuels (oil and others) and electricity, which contributed 48% and 45%, respectively, to the energy mix in 2019. Other sources with minimal contributions include biomass, with a 7% share. Heat and fossil gas contributed less than 1% to the sector’s energy mix each.

Following a 1.5°C compatible pathway, Ecuador’s buildings sector would need to double its electrification from 45% in 2019 to 90% by 2050. The contribution from liquid fossil fuels would need to reduce to less than 10% by 2050.
Ecuador’s buildings sector could be fully decarbonised by 2052 latest. To achieve this, energy efficiency measures and electrification will play a key role.
Several initiatives are already being implemented, such as the “Programa de Eficiencia Energetica para la cocción”, which is expected to reduce 0.15 MtCO₂ by 2025 through the introduction of induction stoves for household cooking.1 Further reductions could be achieved through electrification, coupled with an increase in renewable energy generation.
Ecuador´s NDC includes also other initiatives; however, these are conditional on international support.2 One such initiative is the “Plan Nacional de Eficiencia Energética” which aims to increase energy efficiency in various sectors, including buildings.3

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.
