In order to control climate change, the International Panel on Climate Change (IPCC) estimates that greenhouse gas emissions will need to fall by about forty percent by 2030. Achieving the target goals will be highly challenging. Yet in Greening the Global Economy, economist Robert Pollin shows that they are attainable through steady, large-scale investments -- totaling about 1.5 percent of global GDP on an annual basis -- in both energy efficiency and clean renewable energy sources. Not only that: Pollin argues that with the right investments, these efforts will expand employment and drive economic growth. Drawing on years of research, Pollin explores all aspects of the problem: how much energy will be needed in a range of industrialized and developing economies; what efficiency targets should be; and what kinds of industrial policy will maximize investment and support private and public partnerships in green growth so that a clean energy transformation can unfold without broad subsidies. All too frequently, inaction on climate change is blamed on its potential harm to the economy. Pollin shows greening the economy is not only possible but necessary: global economic growth depends on it. (Publisher)

David Gordon was, at once, a highly creative economist with an enormous range of interests, while also uncompromising in maintaining rigorous research standards. He was focused equally on hard-core academic research and pressing policy issues. He was also openly committed to the political left, with this commitment animating all his work. One distinctive feature of Gordon's work was his keenness to dive into the most important topics engaging mainstream economists and to inject explicitly left political economy perspectives into these mainstream debates. This paper focuses on two important examples of Gordon's contributions that examine front-and-center mainstream macroeconomics questions. The first is the relationship between aggregate saving and investment. The second is the development of the concept of the 'natural rate of unemployment.' The evolution of mainstream research on these two questions played a critical role in overturning what had been, over the first two post-World War II decades, a prevailing Keynesian/social democratic consensus, at both the levels of analytic economics as well as economic policy. As the paper reviews, Gordon challenges the analytic findings and policy implications of these perspectives at their core. Gordon's own basic premises and results are straightforward. He argues that, in fact, investment decisions, not saving rates, are the main driver of economic activity in capitalist economies and that operating capitalist economies at something akin to genuine full employment—i.e. in the range of 2 – 3 percent official unemployment—is a realistic goal. As such, these papers by Gordon contribute significantly toward envisioning a post-neoliberal social structure of accumulation that is committed to the egalitarian principles that were central to Gordon's life work.

In Europe, and elsewhere, it is critical to recognize that this clean energy investment project will pay for itself in full over time in strictly financial terms – i.e. in addition to its obvious ecological benefits.

This paper summarizes a global Green New Deal program that can advance climate stabilization as well as rising mass living standards and an expansion of decent job opportunities. The core features of this program are massive global investments in energy efficiency and clean renewable energy so that clean energy supplants the existing fossil-fuel-dominant global energy system. Through annual investments in the range of 2 percent of global GDP in clean energy and a corresponding contraction in fossil fuel consumption, the global economy can maintain an absolute decoupling trajectory—i.e., economic growth proceeds while CO2 emissions fall to zero within 30–40 years. The paper also shows that a steady contraction of global GDP—i.e., "degrowth"—does not provide a viable climate stabilization framework. JEL Classification: Q54, Q56, Q58
