For the world's 20 largest emitters, we use a simple trend/cycle decomposition to provide evidence of decoupling between greenhouse gas emissions and output in richer nations, particularly in European countries, but not yet in emerging markets. If consumption-based emissions—measures that account for countries' net emissions embodied in cross-border trade—are used, the evidence for decoupling in the richer economies gets weaker. Countries with underlying policy frameworks more supportive of renewable energy and climate change mitigation efforts tend to show greater decoupling between trend emissions and trend GDP, and for both production- and consumption-based emissions. The relationship between trend emissions and trend GDP has also become much weaker in the last two decades than in preceding decades.

This paper asks how well Okun’s Law fits short-run unemployment movements in the United States since 1948 and in twenty advanced economies since 1980. We find that Okun’s Law isa strong and stable relationship in most countries, one that did not change substantiallyduring the Great Recession. Accounts of breakdowns in the Law, such as the emergence of“jobless recoveries,” are flawed. We also find that the coefficient in the relationship—the effect of a one percent change in output on the unemployment rate—varies substantially across countries. This variation is partly explained by idiosyncratic features of national labormarkets, but it is not related to differences in employment protection legislation.

This report explores technological possibilities and opportunities for developing and developed countries to accelerate decoupling and reap environmental and economic benefits of increased resource productivity. It examines policy options successful in helping different countries improve resource productivity in various sectors of their economy, avoiding negative impacts on the environment. It does not seem possible for a global economy based on the current unsustainable patterns of resource use to continue into the future. Economic consequences of these patterns are already apparent in increases in resource prices, increased price volatility and disruption of environmental systems. The environment impacts are also leading to potentially irreversible changes to the world's ecosystems, often with direct effects on people and the economy - for example: damage to health, water shortages, loss of fish stocks or increased storm damage. This report shows that much of the policy design 'know-how' needed to achieve decoupling is present in terms of legislation, incentive systems, and institutional reform. Many countries have tried these out with tangible results, encouraging others to study and where appropriate replicate and scale up such practices and successes

We provide a comprehensive analysis of the relationship between greenhouse gas (GHG) emissions and GDP in China using both aggregate and provincial data. The Kuznets elasticity is about 0.6 for China, higher than that in advanced countries but below that of major emerging markets. The elasticity is somewhat lower for consumption-based emissions than for production-based emissions, providing mild evidence consistent with the “pollution haven” hypothesis. The Kuznets elasticity is much lower for the last three decades than for the three previous decades, suggesting a longer-term trend toward decoupling as China has become richer. Further evidence of this comes from provincial data: richer provinces tend to have smaller Kuznets elasticities than poorer ones. In addition to the trend relationship, we find that the Environmental Okun's Law holds in China.

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.

Too often amongst policy makers and thought leaders an assumption is made that we must make a choice between tackling climate change and having a strong economy; tackling climate change and allowing poorer nations to develop; tackling climate change and having a secure energy system. However, a decade of advanced modelling tested against historical data has provided wide evidence that well-chosen policies can be implemented that avoid these apparent either/or choices.This highly interdisciplinary book provides an overview of potential pathways for the decarbonisation of the global economy. By examining the entire global economy, we show policy-makers and thought-leaders that greatly reducing the risks of climate change can be consistent with energy security, economic development in poor nations, and vibrant economies in already developed nations. Advanced models of the relationships between the economy, energy and climate change pioneered at the Cambridge Centre for Climate Change Mitigation Research (4CMR) over the past decade provides a sound evidence base for decisions. This book examines not only the impacts of policies, but also the feasibility of bringing them forward and the ways in which energy, climate and economic policies can and must be joined up if climate, energy and economic goals are to be met globally.Economists, physicists, engineers, policy analysts, environmental scientists, climate scientists, political analysts, lawyers and computational scientists are brought together for the first time to produce analyses that make up a unique approach to a global problem that must be addressed sooner rather than later.
