This paper estimates fossil fuel subsidies and the economic and environmental benefits from reforming them, focusing mostly on a broad notion of subsidies arising when consumer prices are below supply costs plus environmental costs and general consumption taxes. Subsidies are $4.9 trillion worldwide in 2013 and $5.3 trillion in 2015 (6.5 percent of global GDP in both years). Undercharging for global warming accounts for 22 percent of the subsidy in 2013, air pollution 46 percent, broader vehicle externalities 13 percent, supply costs 11 percent, and general consumer taxes 8 percent. China was the biggest subsidizer in 2013 ($1.8 trillion), followed by the United States ($0.6 trillion), and Russia, the European Union, and India (each with about $0.3 trillion). Eliminating subsidies would have reduced carbon emissions in 2013 by 21 percent and fossil fuel air pollution deaths 55 percent, while raising revenue of 4 percent, and social welfare by 2.2 percent, of global GDP.

Capital flow and commodity cycles have long been connected with economic crises. Sparse historical data, however, has made it difficult to connect their timing. We date turning points in global capital flows and commodity prices across two centuries and provide estimates from alternative data sources. We then document a strong overlap between the ebb and flow of financial capital, the commodity price super-cycle, and sovereign defaults since 1815. The results have implications for today, as many emerging markets are facing a double bust in capital inflows and commodity prices, making them vulnerable to crises. 

Planetary boundaries: Guiding human development on a changing planet

The relatively stable, 11,700-year-long Holocene epoch is the only state of the Earth System (ES) that we know for certain can support contemporary human societies. There is increasing evidence that human activities are affecting ES functioning to a degree that threatens the resilience of the ES—its ability to persist in a Holocene-like state in the face of increasing human pressures and shocks. The Planetary Boundary (PB) framework is based on critical processes that regulate ES functioning. By combining improved scientific understanding of ES functioning with the precautionary principle, the PB framework identifies levels of anthropogenic perturbations below which the risk of destabilization of the ES is likely to remain low—a “safe operating space” for global societal development. A zone of uncertainty for each PB highlights the area of increasing risk. The current level of anthropogenic impact on the ES, and thus the risk to the stability of the ES, is assessed by comparison with the proposed PB
