Carbon lock-in occurs when high-emission infrastructure or assets continue to be used, despite the possibility of substituting them with low-emission alternatives, thereby delaying or preventing the transition to near-zero or zero-emission alternatives. Transition finance, which focuses on the dynamic transformation and decarbonisation of hard-to-abate sectors, frequently faces the issue of carbon lock-in, particularly in considerations of investment feasibility and eligibility.

Carbon lock-in occurs when high-emission infrastructure or assets continue to be used, despite the possibility of substituting them with low-emission alternatives, thereby delaying or preventing the transition to near-zero or zero-emission alternatives. Transition finance, which focuses on the dynamic transformation and decarbonisation of hard-to-abate sectors, frequently faces the issue of carbon lock-in, particularly in considerations of investment feasibility and eligibility. Despite most transition finance approaches incorporating lock-in avoidance as a core principle, existing transition instruments and approaches put in place varying or limited mechanisms to prevent lock-in.Building on the OECD Guidance on Transition Finance, this report takes stock of how carbon lock-in risk is addressed in existing transition finance approaches (such as taxonomies, roadmaps, or guidance), financial instruments, and relevant public and private investment frameworks and methodologies. The report provides good practices on the integration of credible mechanisms to prevent carbon lock-in, address greenwashing risks and build confidence in the market. It can inform both public and private actors in the development of transition finance approaches, standards for green, transition and sustainability-linked debt, frameworks for corporate transition plans, or broader climate-related disclosure frameworks.

This guidance sets out elements of credible corporate climate transition plans, which aim to align with the temperature goal of the Paris Agreement. Such plans are needed to address the growing risk of greenwashing in transition finance and facilitate a global, whole-of-economy climate transition.

Increasing concerns over the effects of climate change have heightened the importance of accelerating investments in green growth. The International Energy Agency, for example, estimates that to reduce carbon dioxide emissions by 50 percent by 2050, global investments in the energy sector alone will need to total US$750 billion a year by 2030 and over US$1.6 trillion a year from 2030-2050. Despite global efforts to mobilize required capital flows, the investments still fall far short. Bloomberg New Energy Finance argues that by 2020 investments will be US$150 billion short from the levels required simply to stabilize CO2 emissions. For the East Asia and Pacific region alone, the World Bank study Winds of Change suggests that additional investments of US$80 billion a year over the next two decades are required.Multiple factors affect green investments, often rendering them financially not attractive. Private investment flows, therefore, depend on public sectors interventions and support. As in many countries public sector resources are scarce and spread across many competing commitments, they need to be used judiciously and strategically to leverage sufficient private flows. Many governments, however, still lack a clear comprehensive framework for assessing green investment climate and formulating an efficient mix of measures to accelerate green investments and are unfamiliar with international funding sources that can be tapped. To address this challenge, the World Bank, with support from AusAID, conducts the work on improving the financing opportunities for green infrastructure investments among its client countries. This activity attempts to identify practical ways to value and monetize environmental externalities of investments and improve the promotion and bankability of green projects. This research report, as a key step in this activity, provides a structured compendium of ongoing leading initiatives and activities designed to accelerate private investment flows in green growth. It summarizes current investment challenges of green projects as well as proposed solutions, financing schemes and instruments, and initiatives that have set the stage for promoting green growth. The results of this work are intended to benefit the international community and policymakers who are seeking to deepen their knowledge of green investment environment. In addition, it is hoped that this work will be useful to practitioners, including fund managers and investors, seeking to have a better understanding of current trends, global initiatives, and available funding sources and mechanisms for financing green projects.

Environmental finance, particularly energy efficiency and renewable energy (EERE) finance, can and should serve as an interface to other sub-sectors of financial sector promotion such as microfinance, housing finance or agricultural finance. For example, existing clients of financial institutions include small and medium-sized enterprises and households, and these are often suffering from high energy prices or have no access to sustainable energy supply. At the same time, these clients are vulnerable to extreme weather events, and often hit hardest by the impact of climate change. There are many other examples which show that the financial sector has an enormous potential to support “green” investments. In order to tap this potential on a sustainable basis, it is important to have a sound understanding which role financial institutions can and should play. This book provides a blend of well-founded professional and scientific perspectives on the potential of Environmental finance in developing and transition countries.

The book provides readers with essential insights into key issues in connection with planning, developing and financing sustainable energy projects in China that are relevant for practitioners, investors and developers involved in the emerging sustainable energy sector. It offers readers a deeper understanding of these contemporary issues by drawing on the lessons learned in real-world sustainable energy and green finance development activities in China, which are driven by central planning and policy implementation and complemented by investments and finances from public-private partnerships.

Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is scarce, however, on the most effective policy mix and the role of mitigation tools and goals in the overall policy framework.

Praise for Carbon Finance "A timely, objective, and informative analysis of the financial opportunities and challenges presented by climate change, including a thorough description of adaptive measures and insurance products for managing risk in a carbon constrained economy." —James R. Evans, M. Eng. P. Geo., Senior Manager, Environmental Risk Management, RBC Financial Group "Climate change will have enormous financial implications in the years to come. How businesses and investors respond to the risks and opportunities from this issue will have an enormous rippling effect in the global economy. Sonia Labatt and Rodney White's insights and thoughtful analysis should be read by all who want to successfully navigate this global business issue." —Andrea Moffat, Director, Corporate Programs, Ceres "In Carbon Finance, Labatt and White present a clear and accessible description of the climate change debate and the carbon market that is developing. Climate change is becoming an important factor for many financial sector participants. The authors illustrate how challenges and opportunities will arise within the carbon market for banking, insurance, and investment activities as well as for the regulated and energy sector of the economy." —Charles E. Kennedy, Director and Portfolio Manager, MacDougall, MacDougall & MacTier Inc. "Climate change is the greatest environmental challenge of our generation. Its impact on the energy sector has implications for productivity and competitiveness. At the same time, environmental risk has emerged as a major challenge for corporations in the age of full disclosure. Carbon Finance explains how these disparate forces have spawned a range of financial products designed to help manage the inherent risk. It is necessary reading for corporate executives facing challenges that are unique in their business experience." —Skip Willis, Managing Director Canadian Operations, ICF International "In this timely publication, Labatt and White succeed in communicating the workings of carbon markets, providing simple examples and invaluable context to the new and changing mechanisms that underpin our transformation to a carbon-constrained world. Carbon Finance will be the definitive guide to this field for years to come." —Susan McGeachie, Director, Innovest Strategic Value Advisors, Graduate Faculty Member, University of Toronto; and Jane Ambachtsheer, Principal, Mercer Investment Consulting, Graduate Faculty Member, University of Toronto
