Global issues like climatic change, high rates of urbanization, and social injustices need sustainable infrastructure to address them. This is a critical chapter of analysis of the international and regional policy framework, which support sustainable infrastructure through the approach of a mixed-method. World bank, Sustainable Development report, OECD and Climate Policy Initiative provide quantitative results that show stark differences between the West Europe/East Asia and Sub-Saharan Africa/South Asia on account of differences in governance, investment and institutional capacity. Good governance and innovative finance and involvement of stakeholders were evidenced through case studies such as the Thames Tideway Tunnel (UK), Hornsdale Power Reserve (Australia), Desert to Power Program (Africa), China Belt and Road green projects and Frenchay Brook Sustainable Drainage System (UK). Some of its most prioritized issues are $6.9 trillion funding shortfall each year, disempowered governance, and missing common metrics. Recommendations include harmonization of policies, an increase in the financing facilities, improvement of governance and capacity building and promotion of technology transfer. This chapter gives evidence-based frameworks to assist in constructing accommodating, strong infrastructure that is in conformity to the SDGs and also in agreement to the Paris accord.
