This study explores the barriers, drivers, and critical success factors of the zero-carbon industry, using Sri Lanka as a case study representing the South Asian region. This chapter begins with a literature review, and fourteen (14) in-depth interviews were conducted with industry experts, policymakers, renewable energy and sustainability experts, and representatives from critical non-governmental organisations in Sri Lanka. The significant barriers that have been pointed out include, firstly, economic barriers; secondly, there are a lot of technological barriers. Thirdly, there are policy and regulatory barriers. Last, there is much social and cultural resistance to change. Conversely, the drivers of the zero-carbon industry also fall into four key categories: economic, technological, policy and regulatory, and social and cultural. These drivers are interconnected with the barriers; when the respective challenges are effectively addressed, they can become powerful motivators for the progression. Critical success factors defining the transitional stage are strategic planning and management, stakeholder engagement and collaboration, innovation and technology advancement, financial resources and investment, policy support and regulatory compliance, market readiness and consumer acceptance. The chapter concludes with a reflection on policy-making processes, the interaction of various barriers and drivers, and research activities with a focus on the necessity of an integrated approach to reach the critical goal of having a zero-carbon economy. Perhaps it would be easier for stakeholders to upsurge the prospects for change toward a sustainable and resilient zero-carbon industry through economic and technological elements and the policy and social aspects.
