The impact of private equity investment and renewable energy on environmental degradation: evidence from BRICS countries

Abstract

Purpose Large-scale industrialization, growth and development have come at the cost of severe environmental degradation, primarily measured in terms of carbon dioxide emissions. Apart from the several measures taken to reduce enviornmental degradation, provision of private capital is a necessity apart from the public capital. There is a debate on impact of carbon dioxide emissions with increase in affluence, technology, population and renewable energy. The purpose of the study is to look into the role of private equity investment on renewable energy and technological patents. Design/methodology/approach The study extends the use of stochastic impact by regression on population, affluence and technology model to include another factor for investments and capital, i.e. private equity along with renewable energy, population, technology and GDP growth on carbon emissions for the BRICS countries. The time period for the study is from 2002 to 2021, and the relationship between the variables has been tested using pooled mean group/autoregressive distributed lag, fully modified ordinary least squares and panel quantile regression. Findings First, the results depict a log-run relationship between the variables across the panel using cointegration. Private equity investments do not have a significant impact on carbon emissions. The study proposes important policy implications. There are two schools of thought on the impact of private equity on carbon emissions. For example, inherently private equity investments come with higher stakes and a shorter holding period because of which their primary focus remains on having higher returns instead of responsible investing. However, as private equity adds up to capital, which leads to an increase in productivity and eventually higher economic growth, this could affect carbon emissions. This study supports the first thought. Additionally, renewable energy also affects carbon emissions positively. The policymakers should look into the role and intent of the private equity investors in green investments and invest in technologies and patents that can lead to energy consumption. Originality/value The paper is the first of its kind, to the best of the authors’ knowledge, to look into the impact of private equity on renewable energy and technological patents.

Could Globalization and Renewable Energy Contribute to a Decarbonized Economy in the European Union?

“…For both tests, the null hypothesis of homogeneous unit root states that "all sections in the panel are nonstationary", while under the alternative hypothesis, "at least, one individual section is stationary". Both tests are largely used in the literature regarding the impact of various economic, financial or energy variables, such as: globalization, economic growth, financial development, renewable/non-renewable energy on carbon emissions or environmental quality [115,[126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141][142][143][144][145].…”
