    Sustainability in the wake of crisis: Transforming climate change-induced disasters into drivers of renewable energy innovation in business
    (Elsevier BV, 2024-12) Rastegar H; Sajjad A; Eweje G; Kazunori K
    This study examines how climate change-induced disasters affect renewable energy innovation in United States-based firms. To this end, we utilized the behavioral theory of the firm and the threat rigidity model to investigate strategic decision-making in the context of environmental crises. We employed a difference-in-differences approach combined with meta-analysis. Further, we analyzed data from 2013 to 2018 and found a significant increase in renewable energy innovation following climatological disasters, marked by an effect size of 0.74. However, firms exceeding their aspiration levels exhibit a smaller impact, reducing the effect on renewable energy innovation by 0.273 units. Additionally, firms with a frequent history of climatological disasters showed a decrease in renewable energy innovation, with an effect size of -0.349. Our research contributes to green innovation literature, particularly to renewable energy innovation discourse under climate challenges. It extends the behavioral theory of the firm to contexts of climatic uncertainty and applies the threat rigidity model to determine organizational adaptation. The study introduces a novel moderator: the firm's history of natural disasters, linking firm age with disaster frequency and severity. These insights are vital for enhancing strategic decision-making in the business and policy-making contexts, amidst the growing climate change challenges.

    The impact of environmental policy on renewable energy innovation: A systematic literature review and research directions
    (ERP Environment and John Wiley and Sons Ltd, 2024-01-03) Rastegar H; Eweje G; Sajjad A
    Renewable energy innovations are imperative to tackle the climate change crisis. However, there is a gap in the literature regarding the effectiveness of environmental policies in promoting renewable energy innovations. To bridge this gap, we have adopted a systematic literature review process covering the period from 2005 to 2023. We identified and analysed 29 articles in our final sample. Further, we employ two levels of analysis (individual-policy and policy-mix levels) for analysing the extant research. Our findings show that fiscal incentives and emissions trading policies such as the European Union (EU) Emissions Trading System (ETS) consistently promote renewable energy innovations. In contrast, the effectiveness of feed-in tariffs and quotas in supporting renewable energy innovations varies, reflecting diverse impacts across distinct regions and renewable energy technologies. Our analysis also suggests that combinations of various policy types can enhance innovation more effectively than individual policies. We contribute to the extant literature by developing a classificatory analysis of the effect of environmental policies on renewable energy innovations. Our review also provides research directions for future scholarship.
