Putting A Price on Carbon: Nations Opt For Market-Based Solutions

Climate change is a threat to global development and to poverty alleviation. And yet, reducing greenhouse gas emissions is proving difficult because all players in an economy contribute to the problem. To make a difference, we must reduce our emissions in a coordinated manner.

This is no easy task. So where do we go from here?

One approach involves pricing the “externalities” that are contributing to climate change. Pricing externalities into the costs of production is nothing new. A classic textbook example is the paper mill that sits upstream from a fishing village.

Discharge from the mill pollutes the river, diminishing the fishermen’s catch. The mill freely uses the water of the river in its production of paper, but does not pay for the damage of the negative externality that it causes. To remedy the situation, regulations can be put in place to stop waste from going into the river – or the mill can pay a fine equivalent to the loss of the fishermen’s revenue.

The latter is an example of an externality priced into the cost of production. The same can be done to combat climate change.

In this case, carbon emissions are the externality that must be priced. Doing so provides a cost-effective and efficient means to drive down greenhouse gas emissions as the cost of such pollution goes up.

Set the Right Price on Carbon and Investors Will Come

This was not the time to discuss the science of climate change, or ways to protect coastal cities against monster storms.

The development experts, journalists, policy wonks and investment professionals who gathered at the Center for Global Development in Washington this week were there to sort out a much thornier issue: How to mobilize and spend the $700 billion or so the world will need annually – above what’s already being spent – to slow and adapt to climate change.

Their consensus: Current levels of public and private finance won’t even begin to do the job.

Can Carbon Taxes Be Effective?

Arne Hoel/World BankIt was heartening to attend the recent Partnership for Market Readiness (PMR) forum at the World Bank, where countries renewed their commitments to testing and piloting market-based instruments for greenhouse gas emission reduction. The PMR is country-led and builds on countries’ own mitigation priorities. Focus is placed on improving a country's technical and institutional capacity for using market instruments to scale up climate change mitigation efforts.
