RESUMO
The greatest contribution to global CO2 emissions comes from the BRICS countries (Brazil, Russia, India, China, and South Africa). The building sector in these countries is one of the sectors that increases CO2 emissions significantly. Increasing CO2 emissions in the building sector adversely affects sustainable development. Therefore, measures to mitigate environmental damage become substantially important. Improvements in technological innovation can be among the measures considered to mitigate CO2 emissions. In this study, the effects of technological innovation on the carbon emissions caused by the building sector are examined by panel data methods for the BRICS countries in the period 1992-2018. It has been observed that there is a long-term relationship between the series. As the results of Dynamic Common Correlated Effects indicated, increased technological innovation reduces carbon emissions. This result is meaningful to encourage investments related to technological innovation.

In all countries, the priority of policymakers is to reduce carbon emissions without reducing economic growth performance. Progress in innovation is one of the main measures that can be used to reduce carbon emissions. It is important to demonstrate the impact of innovation at the sectoral level, in terms of more realistic data on policy measures. The aim of this study is to investigate the effects of innovation on carbon emissions on a sectorial basis for fourteen countries in the G20, for the period between 1991 and 2017. The selected countries are Argentina, Brazil, Canada, France, Germany, India, Indonesia, Japan, Korea, Mexico, South Africa, Turkey, the United Kingdom, and the United States for which data is available. The results show that the Environmental Kuznets Curve (EKC) hypothesis is invalid and, in the long-term, innovations did not have a statistically significant effect on the energy sector, transport sector, and other sectors. It was also found that while an increase in innovation in the industrial sector leads to a reduction in carbon emissions, an increase in innovation in the construction sector increases carbon emissions. Therefore, it can be recommended that, in addition to national policies to reduce CO2 emissions, specific policies should be implemented for each sector separately.
