One of the concerns in the debate on climate change is whether financial flows contribute to the reduction of emissions. This column looks at the role bond market-based and bank-based debt plays in the allocation of resources to fossil fuel in the context of the risk of stranded assets. The authors show that banks continue to provide financing to fossil fuel firms that the bond market would not finance as long as they do not price the risk of stranded assets. In this setting, stranded assets risks may have shifted to large banks.

The UK’s 2008 Climate Change Act has led to a 34% fall in CO2 emissions by 2019, while real GDP per capita had risen by more than 10% following the crash into the ‘Great Recession’. Can the UK achieve its recent net-zero emissions target by 2050 while still growing? This column describes some speculative routes to such a decarbonised future.

While the energy transition to decarbonise the EU’s economy fully by 2050 will be felt economically in all member states, the costs of decarbonising can be substantially lowered through maximising the production of hydrogen, which in turn can be used to generate electricity. This column uses a global climate-energy economic model to compare three energy production scenarios. It finds that wind energy plus gasification of biomass, natural gas, or coal with carbon capture storage can reduce the cost of achieving Europe’s 95% emissions-reduction goal by 40%.

There is reasonable hope that the upcoming United Nations Conference on Climate Change in Paris (COP21) will reach a consistent global climate agreement. What makes the negotiations particularly difficult is not economic efficiency, but the equity implications of climate policy. This column presents a framework for incorporating equity concerns into policy design. Building from four equity principles, it reduces the complex problem of international burden sharing to a simple rule tied to a single metric.

Using a rich dataset for the European car markets, this column shows that consumers moderately undervalue future fuel costs. This investment inefficiency is too small to justify upfront car taxes to promote fuel efficient cars. A car tax results in a more fuel efficient vehicle fleet than a fuel tax, but fails to induce high-mileage consumers to substitute to more fuel efficient cars. Once we take this targeting effect into account, fuel taxes turn out to be more effective.

No comprehensive database of directly measured fossil-fuel subsidies exists at the international or the sub-national level, yet subsidies may be crucial drivers of global carbon emissions. This column describes a novel method for inferring carbon subsidies by examining country-specific patterns in carbon emission-to-output ratios, known as emission intensities. Calculations for 170 nations from 1980-2010 reveal that fossil-fuel price distortions are enormous, increasing, and often hidden. These subsidies contributed importantly to increasing emissions and lower growth.

Reforming fossil fuel subsidies might seem to be an easy option – reduced fiscal outlays would help with debt problems while also helping to reduce greenhouse gas emissions. This column argues that, despite growing interest in reforming them, there still exists much confusion over the concept and magnitude of fossil fuel subsidies – and this needs to change first.

The concern over the negative consequences of global warming has led to a vast array of policy measures aimed at reducing the use of fossil fuels. Yet a comprehensive plan for a shift towards more climate-friendly energy is still lacking. This column argues that a major reason for this is that macroeconomists have not been sufficiently active in the policy discussion. It then lays out four lessons from macroeconomics that should be helpful.

Before the industrial revolution, economists considered output to be fundamentally constrained by the limited supply of land. This column explores how the industrial revolution managed to break free from these shackles. It describes the important innovations that made the industrial revolution an energy revolution.

Hans-Werner Sinn, 24 October 2008

According to Hans-Werner Sinn of CESifo, public policy discussion of climate change has focused only on the reduction of demand for fossil fuel, neglecting the supply side. In an interview with Romesh Vaitilingam, recorded at the annual congress of the European Economic Association in Milan in August 2008, he explains his view.
