Climate Talks Over Potluck Dinner

Only Pav Bhaji in Javadekar Tray?

The Climate Chnage negotiations, which are scheduled to last for nearly two weeks, will break down, as they did at Copenhagen in 2009.

For at least two reasons, though, that seems unlikely.

First, despite talk of the need to reach a legally binding agreement on climate change, the Paris conference isn’t aimed at producing an actual treaty. While some parts of the deal, such as the arrangements for monitoring the targeted emission levels, may well be codified, participation in the process will be voluntary, and enforcement will rely largely on peer pressure. The 193 participants in the talks have given up on seeking to forge a direct successor to the 1997 Kyoto treaty, which saw most advanced nations (but not the United States) agree to limit emissions. Instead, they have agreed to hold a huge potluck dinner, in which each country brings what it can.

Cuts Promises: US 28%, EU 40%, Russia 25%

The U.S. delegation is bearing a promise that, by 2025, the United States will reduce greenhouse-gas emissions by 28% compared to the 2005 level.

The European Union says that, by 2030, it will cut emissions by forty per cent compared to the 1990 level. Russia is pledging a cut of twenty-five to thirty per cent relative to the 1990 baseline. Mexico says that, by 2030, it will reduce emissions by at least a quarter relative to a “business-as-usual scenario.”

Malaysia says that, by 2030, it will have cut emissions by forty-five per cent relative to the 2005 level, India 30%. And so on. (The Web site Carbon Brief has compiled a useful list of these pledges, and has analyzed a number of them in depth.)

The decision to forgo a formal treaty was made partly to assuage the concerns of the world’s two biggest polluters, the United States and China. With the Republicans controlling the Senate, there was virtually no chance of a treaty being ratified in this country. Not much has changed in this regard. In 1997, when many advanced countries signed the Kyoto treaty, the first concerted global effort to limit carbon emissions, a frustrated Clinton Administration didn’t even bother sending it to Capitol Hill.

China, for its part, has always insisted that countries should be allowed to tackle climate change in their own way and at their own pace, rather than being subjected to binding international agreements. (In Copenhagen six years ago, China’s recalcitrance was a major reason for the failure to reach a deal.) The key moment came a year ago, when China agreed to cap its over-all carbon emissions by 2030. Since then, senior party officials have said that this date could be brought forward to 2025.

India Hold the Key?

With the potluck-dinner model in place and China having confirmed its attendance at the table, finalizing the agreement will come down to securing the backing of India and other developing countries.

That is the grand principle at stake. The practical sticking point is money. At Copenhagen, rich countries said that they would provide a $100bn a year in aid and investment to help poor countries develop greener forms of power and adapt to climate change. Modi and other leaders from the developing world are understandably keen to nail down this commitment and see it expanded.

Two Degree Line

Originally, the Paris agreement was meant to hold the global rise in temperatures to two degrees centigrade (3.6 degrees Fahrenheit), relative to pre-industrial times. Largely because of all the coal-fired power stations that China, India, and other countries have built in recent years, many climate-change experts now believe that, regardless of what happens in the next couple of weeks, this ceiling will be breached. Scientists associated with the United Nations recently acknowledged that, even if the Paris summit is a success, it will likely only be enough to contain warming to 2.7 degrees Celsius. And many others involved in tackling climate change think that this is an optimistic assessment.

Defenders of the Paris approach say that it’s the best option that is politically feasible. Efforts to produce a more rigid, top-down multinational agreement have foundered, as have moves to promote a global tax on carbon, which many economists advocate. The potluck-dinner approach has gained widespread support, and it could arguably establish a common framework that can be strengthened going forward. Once each country has issued its carbon-emissions target, its progress will be monitored by U.N. experts. Further summits will be held, and new targets could be issued. Over time, the optimists say, the process of tackling carbon emissions will “ratchet up.”

Until recently, the academic consensus was that, given current emissions rates, we had about thirty years left before burning more carbon would cause a dangerous rise in temperatures. (In this context, “dangerous” is defined as an upward move of more than two degrees centigrade.) Now, though, some experts are suggesting that the trigger point could arrive in fifteen to twenty years. Whatever happens in Paris, it is generally agreed that over-all emissions will still be rising in the period leading up to 2030, which means that, if the pessimists are right about the trigger point, it could be too late to prevent a drastic shift in the earth’s climate.
