Does Economic Complexity and Sustainable Energy Transition Impact Carbon Efficiency? Fresh Evidence From BRICS Arup Roy Review of Development Economics, 2026 Transitioning to low‐carbon economic growth is indispensable for achieving sustainable development goals (SDGs) for BRICS countries (Brazil, Russia, India, China, and South Africa), responsible for 45.8% of global CO 2 emissions. Economic complexity (ECI), which assesses the level of sophistication in productivity and economic structure, and renewable energy consumption (RC) impact carbon efficiency, which could be used to achieve the mutually beneficial objectives of economic growth and carbon reduction. Accordingly, this study examines the effect of ECI, energy intensity, and RC on carbon efficiency while controlling for economic development in the context of BRICS using panel data from 1995 to 2020. Methodologically, this study employed the 2nd generation unit root tests, the Westerlund cointegration, and long‐run estimators of CS‐ARDL, CS‐ECM, and AMG. The empirical findings demonstrate that economic complexity and renewable energy positively impact carbon efficiency in the long run. Conversely, there is a decline in carbon efficiency when there is an increase in energy intensity. Additionally, economic growth is shown to enhance carbon efficiency. Moreover, our empirical findings pass robustness assessments in agreement with our primary results. Finally, strategies are implemented in accordance with SDGs 7 and 13 to regulate CO 2 emissions by optimizing their economic structural transformation and transitioning energy sourcing technology.
Eco-Innovation, Corporate Governance and Nation-Level Institutions: A Cross-Country Evidence Arup Roy, Ranjan DasGupta Business Strategy and the Environment, 2025 There is a dearth of empirical research to examine how a firm's internal corporate governance mechanisms would impact eco‐innovation practices under distinctive nation‐level institutions. Therefore, we conducted this study to examine the individual roles of board size, board diversity (i.e., female directors' presence) and board independence in motivating a firm's eco‐innovation practices in an extended cross‐country setting. Furthermore, we examine whether nation‐level institutions moderate our primary study associations. By employing the system generalized method of moment (SGMM) method for panel data of 19 countries from 2010 to 2021, we find a positive impact of board diversity and independence, whereas board size has a significant negative influence on a firm's eco‐innovation practices. However, the political and cultural systems moderate negatively, whereas the education and labour systems and financial systems strengthen our primary findings. The results remain strong even after using additional measurements for dependent variables, addressing endogeneity concerns and using multiple estimating methods to account for bias from omitted variables. Regulators and policymakers can use these findings to formulate stringent institutional policies in regard to nation‐level eco‐innovation.
The impact of foreign direct investment, renewable and non-renewable energy consumption, and natural resources on ecological footprint: an Indian perspective Arup Roy International Journal of Energy Sector Management, 2024 Purpose Globally, India ranks third in greenhouse gas (GHGs) emissions. Decarbonizing India's economy would necessitate significant changes in how the country generates energy, manufactures things, delivers services and manages natural resources. Recently, scholars from different parts of the world have used various indicators like carbon and methane emissions to investigate potential solutions to the global warming problem that has resulted in climate change. Therefore, this study aims to investigate the impact of foreign direct investment, renewable and non-renewable energy consumption, in addition to economic growth, trade openness, and natural resources on ecological footprint. Design/methodology/approach Using India's yearly data from 1990 to 2016, this research investigates the impact of direct foreign investment (FDI), trade (TA) and natural resources (NR) on the ecological footprint (EF) within the framework of economic growth (GDP), renewable (RE) and non-renewable (NRE) energy consumption. The Zivot–Andrews unit root approach was used to examine the structural breaks in data series and the presence of stationary. An auto regressive distributive lag model was used to investigate the presence of long-run and short-run dynamic relationships among the variables. Findings The empirical findings demonstrate that FDI, RE and GDP have a negative and substantial impact on EF in the long term; in contrast, NRE and TA are significant and positive. The Granger causality test indicates that feedback transmission was observed between NR and EF and TA and EF. One-way causation passed from GDP to FDI and NR; TA to FDI and RE. Originality/value Indian Government and authorities should push for an eco-friendly manufacturing process and technology adaptation to improve environmental quality.
Environmental, Social, Governance Performance and Negative Performance Feedback: Firm Moderators in a Cross-country Context Ranjan DasGupta, Arup Roy American Business Review, 2023 In this study, we have examined two specific research questions. First, whether firms around the world with negative performance feedback would resort to more environmental, social, governance [ESG] performance or otherwise. Second, we examine whether firms’ ESG controversies and stakeholder orientation in a cross-country context, with distinctive legal system and ethical behaviour, would motivate them to undertake more ESG performance in such negative performance feedback conditions. Our primary findings show that negative performance feedback of a firm impacts its ESG performance in a strongly negative manner. Furthermore, we prove that both high stakeholder orientation and high ESG controversies significant negatively moderate firms’ ESG inclinations. This holds true irrespective of country-specific legal system and ethical behaviour contexts.
