This paper reviews the fiscal implications of climate change, and the potential role of the Fund in addressing them. It stresses that:
- The potential fiscal implications are immediate as well as lasting, and liable to affect—in differing forms and degree—all Fund members.
- Climate change is a global externality problem, calling for some degree of international fiscal cooperation…
- …and has features—an intertemporal mismatch between the (early) costs of action to address climate change and (later) benefits, pervasive uncertainties and irreversibilities (including risk of catastrophe), and sharp asymmetries in the effects on different countries—that raise difficult technical and ethical issues, and hinder policy coordination.
- In addition to itself impacting the public finances, climate change calls for deploying fiscal instruments to mitigate its extent and adapt to its remaining effects.
Korea’s greenhouse gas emissions almost doubled between 1990 and 2005, the highest growth rate in the OECD area. Korea recently set a target of reducing emissions by 30% by 2020 relative to a “business as usual” baseline, implying a 4% cut from the 2005 level. Achieving this objective in a cost-effective manner requires moving from a strategy based on voluntary commitments by firms to market-based instruments. The priority is to establish a comprehensive cap-and-trade scheme, supplemented, if necessary, by carbon taxes in areas not covered by trading. Achieving a significant cut in emissions requires a shift from energy-intensive industries to low-carbon ones. Korea is strongly committed to promoting green growth through its Five-Year Plan, which envisages spending 2% of GDP per year through 2013. One challenge is to ensure that these expenditures are efficiently targeted so as to develop green technologies, while avoiding the risks inherent in industrial policy.
The working paper is a response to the call for the UN system to support countries interested in pursuing green economy policies by providing methodologies for their evaluation. It aims to provide guidance to policy analysts and advisers, and other stakeholders, who are involved in developing green economy policies by using indicators as a tool for identifying priority issues, formulating and assessing green economy policy options, and evaluating the performance of policy implementation. Emphasis is placed on policy options with “multiple dividends” across the environmental, social and economic dimensions of sustainable development.
