Financing climate-resilient infrastructure: Determining risk, reward, and return on investment

Peter B. MEYER, Reimund SCHWARZE

Frontiers of Engineering Management 2019, Volume 6, Issue 1,   Pages 117-127 doi: 10.1007/s42524-019-0009-4

Abstract:

Urban infrastructure investment is needed for both, mitigation of climate risks and improved urban resiliency. Financing them requires the translation of those benefits into measurable returns on investment in the context of emerging risks that capital markets can understand and appreciate. This paper develops a generic framework to identify what are the necessary and sufficient factors to economically favor climate-change resilient infrastructure in private investment decisions. We specifically demonstrate that carbon pricing alone will not generate the needed will, because market prices at present systematically fail to account for climate change risks such as the costs of stranded assets and the national and local co-benefits of investments in climate resiliency. Carbon pricing is necessary, but not sufficient for an enhanced private financing of climate-resilient infrastructure. The Paris Agreement and other supra-local policies and actors including city networks can concretely help to generate the sufficient social and political will for investments into climate change mitigation and resiliency at the city level.

Economic Analysis of Residential Distributed Solar Photovoltaic

Xi Luo,Jia-ping Liu

Frontiers of Engineering Management 2015, Volume 2, Issue 2,   Pages 125-130 doi: 10.15302/J-FEM-2015031

Abstract: Under the huge challenges of global energy conservation, emission reduction and energy security, distributed solar photovoltaic industry has become the key means to achieve economic restructuring and low carbon economy. Based on System Advisor Model software, the authors choose Baoji as the sample plot. Household load, unit investment, loan interest rate and loan fraction are used as influence factors to analyze the economic benefits of distributed solar photovoltaic in China. The result demonstrates that government incentives help to increase the profitability of distributed solar photovoltaic by a large extent; other factors that influence the profitability includes household load, unit investment cost, loan interest rate and loan fraction.

Keywords： distributed solar photovoltaic     internal rate of return     price ladder     government incentives
