Environment & Climate Change

Discussions in Beijing between US President Barack Obama and Chinese President Xi Jinping – the leaders of the world’s two largest carbon-emitting countries – produced an unexpected, groundbreaking bilateral agreement on greenhouse-gas emissions. Under the new deal, the US is to reduce its emissions by 26-28% from 2005 levels within 20 years, and China’s emissions are to peak by 2030. In the absence of a binding global agreement, such unilateral or bilateral commitments by countries to rein in their contribution to global warming represent the most realistic hope for addressing climate change.

My preceding blog post described how market-oriented mechanisms to address environmentally damaging emissions, particularly the cap-and-trade system for SO2 in the United States, have recently been overtaken by less efficient regulatory approaches such as renewables mandates.   One reason is that Republicans — who originally were supporters of cap-and-trade — turned against it, even demonized it.One can draw an interesting analogy between the evolution of Republican political attitudes toward market mechanisms in the area of federal environmental regulation and hostility to the Affordable Care Act, also known as Obamacare.

Markets can fail.  But market mechanisms are often the best way for governments to address such failures.  This has been demonstrated in areas from air pollution to traffic congestion to spectrum allocation to cigarette consumption.    Markets for emission allowances - in which those firms that can cheaply cut pollution trade with those that cannot - achieve desired environmental goals at relatively low economic costs.   As of a decade ago, that long-standing economic proposition had become widely recognized and put into action.

On July 27 negotiators reached a compromise settlement in the world’s largest anti-dumping dispute, regarding Chinese exports of solar panels to the European Union.   China agreed to constrain its exports to a minimum price and a maximum quantity.   The solution is restrictive relative to the six-year trend of rapidly Chinese market share (which had reached 80% in Europe), and plummeting prices.  But it is less severe than what had been the imminent alternative:  EU tariffs on Chinese solar panels had been set to rise sharply on August 6, to 47.

An amazing thing has happened over the last five years.   Against all expectations, American emissions of carbon dioxide into the atmosphere, since peaking in 2007, have fallen by 12%, back to 1995 levels.  (As of 2012. US Energy Information Agency).   How can this be?   The United States did not ratify the Kyoto Protocol to cut emissions of greenhouse gases below 1997 levels by 2012, as Europe did.Was the achievement a side-effect of reduced economic activity?   It is true that the US economy peaked in late 2007, the same time as emissions.

Throughout history, big economic and political shocks have often occurred in August, when leaders had gone on vacationin the belief that world affairs were quiet.   Examples of geopolitical jolts that came in August include the outbreak of World War I, the Nazi-Soviet pact of 1939 and the Berlin Wall in 1961.  Subsequent examples of economic and other surprises in August have included the Nixon shock of 1971 (when the American president enacted wage-price controls, took the dollar off gold, and imposed trade controls), 1982 eruption in Mexico of the international debt crisis, Iraq’s invasion of Kuwait in 1990, the 1991 Soviet coup, 1992 crisis in the European Exchange Rate Mechanism, Hurricane Katrina in 2005, and US subprime mortgage crisis of 2007.

The parties to the UN Framework Convention on Climate Change are meeting once again in Durban, South Africa, from November 28 to December 9.  The period covered by the Kyoto Protocol ends in 2012 and the clock is running out on negotiations for a successor agreement.  Progress at Copenhagen two years ago and Cancun one year ago was slow.   Negotiations have been blocked by a seemingly insurmountable obstacle. The United States is at loggerheads with the developing world, especially China–now the world’s largest emitter of greenhouse gases (GHG)–and India.

Korea may have an opportunity to exercise historic leadership, when it chairs the G-20 meeting in Seoul, November 11-12.    This will be the first time that a non-G-7 country has hosted the G-20 since the larger, more inclusive, group supplanted the smaller rich-country group in April of last year as the premier steering committee for the world economy.  With large emerging market and developing countries playing such expanded economic roles, the G-7 had lost legitimacy.  It was high time to make the membership more representative.

Many observers judged as a failure the December meeting in Copenhagen of the Conference of Parties of the UN Framework Convention on Climate Change (UNFCCC). But then the usual way of judging such meetings is to look for a communiqué that voices sweeping aspirations, such as the proclamations of Bali (2007) and L’Aquila (2009) to limit global warming to 2 degrees centigrade. In reality, without any evidence of countries agreeing what is each one’s share of the burden, such proclamations are worthless.
