“…Accordingly, we agree with Vieira et al ( 2018 ) that any energy efficiency program should involve the industrial sector. Within this scope, another major issue for the Brazilian growth-CO 2 nexus is the lack of technological progress.…”

Since energy is one of the basic inputs for development, emerging economies should make an effort to investigate the environmental impacts of their fast economic growth. However, large emerging economies present significant regional heterogeneity that is usually uncounted for. This study uses the Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model and regional data on the 27 Brazilian states to investigate the growth-CO 2 nexus under distinct development stages. To perform this analysis, we divided the states into three groups according to their average annual GDP (i.e., richer, intermediate, and poorer regions). The results suggest that richer and poorer regions, particularly, present economic and demographic developments that are environmentally costly. Also, population and per capita GDP have the largest influences on CO 2 emissions. The roles of the industrial sector and the ascending service sector are also subject to criticism. Moreover, Brazil arguably suffers from technological stagnation as its energy intensity is growing and boosting CO 2 emissions. We discuss the policy implications of these findings and suggest a future research agenda.

“…Tian, Yang, Zhang, and Liu (2016) found that energy efficiency causes low emissions of CO2 in the commercial truck market. Vieira et al (2018); Khoshroo et al (2018); and Tajudeen et al (2018) indicated that energy efficiency helps to reduce the carbon dioxide emissions.…”

This paper tries to evaluate the impact of manufacturing-industry sector on the level of inefficient consumption of energy in Nigeria. The Fisher Ideal index decomposition analysis and the VEC model are used for results for the time period from 1991 to 2014. The examined findings indicate that energy efficiency in Nigeria is linked with the per capita income from overall country's economic growth, emissions of component of CO2, consumption of energy and investment for industrial production. In Nigeria, however, systemic reform indicates negative impact on energy production. Furthermore, for the short span of time interval, all variables have concluded with a negative relation with the production of efficient energy. According to the findings of this paper, economic growth, low carbon emissions, and industrial investment are all essential for Nigeria's energy efficiency policies to be intensified. As a result, policymakers and the government should take steps to resolve these issues.

“…Furthermore, the use of more efficient cooling technologies could considerably reduce the energy consumption associated with increasing temperatures [9]. In this regard, policies to promote energy efficiency of AC appliances are important to build a sustainable future [10] and are object of new studies [11,12].…”

“…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.
