A Delphi study on identifying environmental risk factors in the construction of China-Pakistan Economic Corridor (CPEC)

Abstract The China-Pakistan Economic Corridor (CPEC) represents a monumental initiative aimed at enhancing economic cooperation between China and Pakistan. However, the construction and operational phases of CPEC are fraught with numerous environmental risks that could impede its successful implementation. This study employs the Delphi method to systematically identify and evaluate the environmental risk factors associated with CPEC. A panel of experts from diverse fields, including environmental science, engineering, and regional planning, participated in multiple rounds of surveys to reach a consensus on the most critical environmental threats. Various studies have addressed general environmental impacts of large-scale projects, there is a gap in targeted research that systematically identifies and evaluates specific environmental risk factors associated with CPEC. This study aims to fill this gap by providing a detailed and consensus-based understanding. The findings highlight key risk areas such as carbon emission, climate change, air quality deterioration, and biodiversity loss. By providing a comprehensive risk assessment, this research offers valuable insights for policymakers, stakeholders, and project managers to develop robust mitigation strategies, ensuring the sustainable development of CPEC. The study underscores the importance of proactive environmental management in large-scale infrastructure projects within ecologically sensitive regions.
