“…In the case of solar energy options for this same sector, the study by Reference [67] proposes for Brazil in its Low-Carbon Scenario that 0.7% of electricity consumption comes from SFV installed in the residential sector in 2030, a goal very similar to the one considered in this article of 1% in 2035. As for the option of solar heaters, the study by Reference [11] proposes in its Advanced Technology scenario that in California, 15% of residential water heating is carried out with solar heaters in 2035 and 44% in 2050.…”

The residential, commercial, and public sectors consume between 20% and 30% of final energy demand worldwide. Due to the intensive use of fossil fuels and conventional electricity, they also have an important participation in the emission of greenhouse gases (GHG). Taking Mexico as a case study, this article develops an alternative scenario that considers that in these sectors, buildings can generate energy for self-consumption or to supply it to the power network—for which four solar energy options are analyzed. In addition, to manage and rationalize the energy demand of these buildings, eight energy efficiency measures are studied. These options were selected on the basis that they are technically and economically feasible to implement in buildings in Mexico. The results reveal that by 2030, in relation to the GHG trend scenario, this mitigation scenario reduces 23.5 million tons of carbon dioxide equivalent (MtCO2e) in the residential (19 MtCO2e), commercial (2.6 MtCO2e), and public services sectors (1.9 MtCO2e), while by 2035 it reaches 45 MtCO2e; which far exceed the avoided emissions goals established in Mexico’s nationally determined contributions (NDC) for 2030 (5 MtCO2e) for the residential and commercial sectors. Therefore, it is possible to increase the ambition for mitigation in these sectors, as well as including the public sector, in a renewed Mexico’s NDC. This mitigation scenario generates a total economic benefit of $7.7 billion, which means that it does not generate an overall incremental cost, but requires an incremental investment of over $9 billion USD, which is a financing challenge to achieve this scenario.

“…The country's AC ownership rate in the residential sector increased by 9% per year between 2005 and 2017, and is expected to continue to grow [31]. However, existing studies about the impacts of climate change on space cooling in Brazil assess the effects of air temperature and humidity on energy demand without considering different patterns of consumption and regional effects [7,25,32], or possible technological changes [12,33]. To date and to the authors' knowledge, no study has specifically analyzed Brazil with a focus on its regional particularities, less so by applying a hybrid methodology that integrates the use of CDDs and end-use modelling.…”

Air Conditioning (AC) appliances are a highly effective adaptation strategy to rising temperatures, thus making future climate conditions an important driver of space cooling energy demand. The main goal of this study is to assess the impacts of climate change on Cooling Degree Days computed with wetbulb temperature (CDD wb ) and household space cooling demand in Brazil. We compare the needs under three specific warming levels (SWLs) scenarios (1.5°C, 2°C and 4°C) to a baseline with historically observed meteorological parameters by combining CDD wb projections with an end-use model to evaluate the energy requirements of air conditioning. The effects of the climate change were isolated, and no future expansion in AC ownership considered. Carbon dioxide (CO 2 ) emissions associated with AC energy demand are also calculated. Results show an increase in both average CDD wb and AC electricity consumption for the global warming scenarios in all Brazilian regions. The Northern region shows the highest increase in CDD wb (187% in CDD wb for SWL 4°C), while the Southeast presents the highest AC energy consumption response (326% in the AC energy consumption for SWL 4°C) compared to the baseline. At the national level, CDD wb and the AC energy consumption in all SWLs scenarios grow by 70%, 99% and 190%, respectively.

“…En América Latina y el Caribe las emisiones comprometidas de las centrales eléctricas actuales son también un 30% superiores a la cantidad promedio de emisiones de carbono del sector eléctrico, que de igual forma son incompatibles con el objetivo de 1,5 °C, de acuerdo con datos los compilados por el Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC, por sus siglas en inglés) (González-Mahecha et al, 2019). Si se construyeran todas las centrales eléctricas de combustibles fósiles que han sido planificadas y anunciadas en la región (la mayoría, plantas de energía de gas natural) empeoraría la situación y las emisiones comprometidas superarían en un 150% el límite establecido.…”

Esta publicación presenta un conjunto de experiencias recientes de ministerios de finanzas de la región de América Latina y el Caribe en tres áreas de intervención donde convergen los temas de cambio climático y las responsabilidades de estos ministerios. Así mismo, la publicación aporta elementos para que el diseño de las políticas fiscales coadyuve a un crecimiento sostenible. Las tres áreas donde las intervenciones de los ministerios de finanzas resultan cruciales son: 1) la gestión de los riesgos económicos, fiscales y financieros asociados a los eventos climáticos extremos y al cambio climático; 2) los desafíos de la transición hacia economías bajas en emisiones de carbono, y 3) la reorientación de las finanzas públicas para que contribuyan a los objetivos nacionales de resiliencia y descarbonización. La publicación también muestra que, aunque los riesgos y desafíos de la transición hacia economías verdes son reales, existe gran cantidad de evidencia que indica que, si dicha transición se planifica e implementa adecuadamente, es posible generar nuevas oportunidades económicas a la vez que se crean más y mejores empleos.
