Sustainable Project Finance and Financial Modelling: A Global Review with Reference to Construction Sector

Complex investment projects need an in - depth examination of several variables and a suitable reaction at each stage. This article addresses the subtleties of project finance, the major risks involved with projects, and the processes for executing recourse and debt payment. The objective of the study is to examine the laws, practices, and research controlling the financing of sustainable construction projects, and to recommend future research avenues. To accomplish the objectives, we examined sustainable building finance patterns in four developed economies: the UK, USA, Singapore, and Australia. The study then looked at the activities and objectives of three international organisations: the UN, the OECD, and the IFC. It then analysed peer - reviewed studies on sustainable building project funding. We focused on four main research areas such as financial players and the market for sustainable building, advantages and restrictions of sustainable construction finance, and novel methods. While more money is being invested in sustainable development, a complete look at sustainable building project finance is still lacking. Examine crucial elements impacting the execution of sustainable construction project finance and establish a knowledge base for sustainable construction project financing. This study adds to the body of knowledge by evaluating current sustainable building finance laws, practices, and research. It also helps practitioners learn more about sustainable building project funding. The paper is based on real - world project finance experience and complex investment project analysis.
