We face significant challenges related to sustainability and social responsibility, so sustainable entrepreneurship is a key way to help address these issues. How can sustainable entrepreneurship contribute to combating climate change? This is the question from which this research started. The paper proposes important research directions to develop innovative and sustainable solutions tailored to the problem. By investigating the impact of different innovation strategies, the study aims to provide concrete recommendations to all stakeholders. Recognizing that effective climate action requires collaboration among government, businesses, non-governmental organizations, and citizens, the study emphasizes the importance of raising awareness, education, and access to information. Using fsQCA software version 4.1, the research analyzes various innovation strategies to develop tailored, sustainable solutions. The findings offer concrete recommendations for stakeholders, aiming to facilitate the implementation of sustainable practices and foster a supportive framework for green initiatives. Ultimately, this study contributes to efforts aimed at reducing the carbon footprint and promoting a more responsible economic model in Romania. The results not only provide concrete recommendations for relevant actors but also outline a strategic vision on how a more responsible economic model can be promoted in Romania, with the potential to influence sustainable development policies and inspire future initiatives.

The EU energy sector became a very important one as a result of the war in Ukraine. On the other hand, the EU started in defining and implementing new strategies regarding green economy and sustainability. Even though these strategies cover short and medium periods, they have as a main goal the decrease in the EU’s dependence of energy imports. This research is focused on present challenges, risks, and uncertainties related to energy production and consumption in all EU member states. In order to achieve the research objectives, a huge statistical database, which covered 2012–2021, was used. The analysis is based on specific indicators regarding primary energy production; imports and exports; gross available energy; final energy consumption; non-energy consumption; energy dependency; and energy intensity. There are at least three research procedures used in this paper: a meta-analysis, a statistical analysis, and an econometric analysis, as well. Finally, the analysis points out the disparities between member states regarding energetic resources and energy dependency using a new model for quantifying risk factors in the European energy system. Moreover, new public policies are proposed by the authors under a cluster approach of the EU’s regions.

This study examines the role of business accelerators in fostering startup performance across diverse entrepreneurial ecosystems, focusing on Romania, the United States, and Italy. Using a cross-country comparative approach, this research investigates how accelerators influence grant utilization efficiency, financial management capabilities, sustainable business practices, and income growth and diversification. The findings reveal that accelerators significantly enhance startups’ financial resource management and revenue growth, with variations across the target countries. In Romania, accelerators address structural barriers and resource constraints, while in the United States, they drive sector-specific innovations within a mature ecosystem. Italy highlights a blend of traditional and emerging industries, with accelerators fostering sustainability initiatives and innovation. This study introduces sustainable business practices and financial management capabilities as mediating factors, developing existing theoretical models. Practical implications for entrepreneurs, policymakers, and investors are outlined, emphasizing personalized business accelerator strategies to address contextual challenges.
