Nature commentary: Energy policy- Push renewables to spur carbon pricing

In this comment piece in Nature, a group of researchers argue that putting a price on carbon dioxide and other greenhouse gases to curb emissions must form the centrepiece of any comprehensive climate-change policy.

They point out that the current price of carbon remains much too low relative to the hidden environmental, health and societal costs of burning a tonne of coal or a barrel of oil. The global average price is below zero, once half a trillion dollars of fossil-fuel subsidies are factored in.

While some efforts have been made to price carbon, these are not enough. They also highlight a catch-22 at the heart of the problem: policymakers are more likely to price carbon appropriately if it is cheaper to move onto a low-carbon path. But reducing the cost of renewable energies requires investment, and thus a carbon price.  The authors suggest four ways forward:

  • Check that all climate-change interventions pass a benefit-cost test (taking environmental, health and societal costs into account);
  • Develop policies that ensure that any renewables policy will make a national — and eventually global — carbon cap or tax more likely.  Don’t develop policies that get in the way of this goal.
  • Open up access to electricity grids for renewables and break up any non-competitive arrangements and support the modernization of power grids to facilitate adoption of new renewable energy sources; and
  • View the energy sector in its entirety since transportation may become increasingly dependent on electricity.
