"Cognisant of the many facets of climate change, this report looks through the lens of economics, that is, the social science that measures the economic impact of climate change and the costs and benefits of trying to mitigate it and adapt to it. From an investment perspective, issues for study include the balance between investment in mitigating greenhouse-gas emissions and adaptation to climate change; the urgency and timing of investing in both; obstacles to investment; and policies to remove them and make investment profitable. From a growth perspective, issues of interest include the link between climate action and economic growth; the short-term and the long-term dimensions of this link; and the importance of innovation as an interface between climate action and economic growth. One of the key messages from this report is that there is unexploited scope for making Europe's climate action more efficient, growth-friendly, and in tune with fiscal constraints."--publisher's description.

This report provides an assessment of how governments can generate inclusive economic growth in the short term, while making progress towards climate goals to secure sustainable long-term growth. It describes the development pathways required to meet the Paris Agreement objectives.

We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.

In the crowded field of climate change reports, 'WDR 2010' uniquely: emphasizes development; takes an integrated look at adaptation and mitigation; highlights opportunities in the changing competitive landscape; and proposes policy solutions grounded in analytic work and in the context of the political economy of reform.

This issue of Finance & Development looks at the economic and financial impact of climate policy choices. It points to concrete solutions that offer growth opportunities, driven by technological innovation, sustainable investment, and a dynamic private sector. The private sector can stop supporting or subsidizing industries and activities that damage the planet and instead invest in sustainable development. Governments can roll out policies to fight climate change and the destruction of nature. The paper highlights that technological change and innovations are central to longer-term efforts to mitigate climate change by developing alternatives to fossil fuels. A new, sustainable financial system is under construction. It is funding the initiatives and innovations of the private sector and amplifying the effectiveness of governments’ climate policies—it could even accelerate the transition to a low-carbon economy. The Bank of England’s latest survey finds that almost three-quarters of banks are starting to treat the risks from climate change like other financial risks—rather than viewing them simply as a corporate social responsibility. Banks have begun to consider the most immediate physical risks to their business models—from the exposure of mortgage books to flood risk to the impact of extreme weather events on sovereign risk.

Global temperatures have increased at an unprecedented pace in the past 40 years. This paper finds that increases in temperature have uneven macroeconomic effects, with adverse consequences concentrated in countries with hot climates, such as most low-income countries. In these countries, a rise in temperature lowers per capita output, in both the short and medium term, through a wide array of channels: reduced agricultural output, suppressed productivity of workers exposed to heat, slower investment, and poorer health. In an unmitigated climate change scenario, and under very conservative assumptions, model simulations suggest the projected rise in temperature would imply a loss of around 9 percent of output for a representative low-income country by 2100.

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.
