Governments worldwide have prioritized carbon reduction and neutrality to address the escalating threat of climate change. These goals are in line with the United Nations Sustainable Development Goals (UNSDG-13). These goals stress taking action on climate change to lessen the bad effects of human activities and using fossil fuels for energy. To this end, the present study investigates the connection between conventional energy usage, agricultural practices, economic growth, and their impact on environmental sustainability in South Africa. Additionally, it explores the role of renewable energy consumption and environmental technological innovation in mitigating these effects. To achieve the study objectives, a carbon-income function is fitted with an annual frequency data from 1975 to 2020. The present study leverages on Pesaran's Autoregressive distributed lag (ARDL) method and for robustness analysis the dynamic ARDL simulations method to simultaneously explore the short and long-run coefficients of the study's outlined variables. Empirical analysis, confirmed by bounds testing for cointegration, reveals a long-term equilibrium relationship among the variables considered. Notably, economic growth, fossil fuel energy consumption, and agricultural activities have adverse effects on environmental sustainability in South Africa, indicating a trade-off between economic growth and environmental quality. Dynamic ARDL simulations provide further evidence of an Environmental Kuznets Curve (EKC) phenomenon. However, renewable energy consumption and environmental technological innovation positively influence environmental quality. These findings highlight the imperative for South Africa and its stakeholders to adopt green growth policies and transition to cleaner energy alternatives. • This study explored nexus between environmental pollution, economic growth, and environmental technological innovation in South Africa • Utilisation of Autoregressive distributed lag (ARDL) estimators were employed • Agricultural activities dampens environmental sustainability in South Africa • Green growth policies should be pursued in South Africa energy mix [ABSTRACT FROM AUTHOR]

Growing concern over climate change mitigation has heightened the search for low-carbon, affordable, and non-intermittent energy alternatives. In this perspective, hydropower, thermal, solar, photovoltaic, and nuclear energy sources fit all these qualities as they are well-known as cleaner and ecosystem-friendly energy sources. However, despite the attractiveness of the clean energy transition, the extant literature has less documentation on the pertinent role of nuclear energy in the "climate change mitigation (SDG-13)" agenda, hence making it difficult to predict nuclear energy-CO 2 emissions (CO 2 e) nexus. Hence, the present study, using IPAT and the "environmental Kuznets curve (EKC)" framework, explores the consequences of nuclear energy generation, population dynamics, and economic progress on CO 2 e in the "United States of America (USA)" by applying a "dynamic autoregressive distributed lag (DARDL)" model from 1973 to 2021. The study provides evidence the existence of the EKC phenomena, suggesting that economic expansion hurts the environment up to a specific threshold level of per capita income, which is identified as US$ 29,581.16. Further empirical findings also show the detrimental effect of population-induced-emission. Remarkably, a 1% rise in nuclear energy generation dwindles CO 2 e by around 0.819%. The outcomes of this research demonstrate that economic growth level, population, and CO 2 emission are entangled. However, there is a need for a collective role from both stakeholders and policymakers in achieving "SDG-13" as well as "clean and affordable energy (SDG-7)" with a paradigm shift of the USA energy portfolio away from fossil fuels to renewables. • The nexus between nuclear energy-population-CO 2 emissions is investigated for USA. • We applied dynamic ARDL simulations model. • Environmental Kuznets Curve (EKC) hypothesis prevails in USA. • Nuclear energy generation dampens the effect of CO 2 emission. • The population induced-emission in both the short- and long-run is observed.

Although technological innovation plays a critical role in promoting sustainable development and environmental sustainability, there are few studies in the existing literature that address this relationship. This study aimed to investigate the relationship between technological innovation (TI), renewable energy consumption (REC), natural resource rent (NRR) and ecological footprint (EF) of E-7 countries (i.e. Brazil, China, India, Indonesia, Mexico, Russia and Turkiye) from 1992 to 2018 in order to ensure environmental sustainability in the context of the Sustainable Development Goals (SDGs). Analysis was performed using the ARDL estimator, robustness test and Dumitrescu-Hurlin panel causality (DHC) test. Long-term empirical estimates from the PMG-ARDL technique have shown that a 1 % increase in TI and REC reduces EF by 0.064 % and 0.234 %, respectively, i.e. increases environmental sustainability. At this point, it is possible to say that TI and REC contribute to the achievement of SDG-7 and 13 in E-7 countries while NRR and real income (GDP) were found to impede the achievement of SDG-7 and 13 in E-7 countries through an increase in EF. The results were confirmed using robustness techniques. In the DHC test results, while there is a unidirectional causality from TI to EF, from EF to NRR and trade openness, a bidirectional causality was found between GDP and EF. This study suggests that policymakers should focus on introducing environmentally friendly equipment to reduce environmental degradation, increase the share of RECs and focus on sustainable development within the framework of the SDGs. • We explore nexus between technological innovation affect the ecological footprint in E-7 economies. • Adoption of second-generational panel econometrics techniques. • Technological innovation and renewable energy consumption help in mitigating climate change. • Green growth policies should be pursued in E7 energy mix.
