Climate change agenda is hotting up

Having failed to achieve consensus on climate change policies in Copenhagen in 2009, the UN is set to try again, writes Michael Jacobs

Climate change agenda is hotting up

FOR many people around the world this year, the weather has become anything but a topic for small talk.

Typhoon Haiyan in the Philippines, in the US a record- breaking freeze and year-long drought in California, and flooding in Europe have put the long-term dangers of climate change back on the political agenda. In response, UN Secretary General Ban Ki-moon has sent an urgent letter to government, business, civil society, and finance leaders, urging them to attend a special climate summit in New York in September.

The event will be the first time world leaders have met to discuss global warming since the UN’s fateful Copenhagen climate change summit in 2009. Amid high expectations and subsequent recriminations that meeting failed to achieve a comprehensive, legally binding agreement to reduce greenhouse gas emissions.

So, at September’s summit, leaders will be asked to reboot the diplomatic process. The goal is a new agreement in 2015 to prevent average global temperatures from rising by two degrees celsius, the level that the international community has deemed dangerous to human society.

At first sight, that looks like a hard task. Since Copenhagen, climate change has slipped down the global agenda, as the restoration of economic growth, voter concern about jobs and living standards, and violent conflict in key trouble spots have taken precedence.

However, the tide may be turning. More people are grasping the true extent of the dangers ahead. In its latest authoritative assessment, the Intergovernmental Panel on Climate Change concluded last year that scientists are now 95% certain that human activities are the principal cause of rising temperatures. Over the next two months, the IPCC will release further reports detailing the human and economic impacts of probable climate change and the costs and benefits of combating it.

US Secretary of State John Kerry recently described climate change as “perhaps the world’s most fearsome weapon of mass destruction”, warning of “a tipping point of no return”. Few serious commentators now dispute the science.

So the key question now is how the world’s leaders will respond. There are grounds for optimism.

First, New York will not be like Copenhagen. Leaders are not being asked to negotiate a new agreement themselves; that job will remain with their professional negotiators and environment ministers.

Moreover, the process will not be concluded this year but at the UN climate conference in Paris in December 2015. That provides plenty of time to translate political commitments made in New York into a legally binding accord.

Second, the world’s two largest greenhouse-gas emitters, the US and China, are more committed to action than they were five years ago. US president Barack Obama has announced a plan authorising the Environment Protection Agency to take dramatic measures in the next few months to limit power-station emissions, virtually ending coal-fired electricity altogether.

In China, worsening air pollution and growing concerns about energy security have led the government to consider a cap on coal use and an absolute reduction in emissions within the next 10 to 15 years.

Further, the two countries are actively co-operating. Last year Obama and Chinese president Xi Jinping committed to phase out hydrofluorcarbons, a potent greenhouse gas. In February, they announced their intention to work together on climate policy — a marked contrast to Sino-US tensions over Pacific security and trade issues. With the EU also preparing to commit to new 2030 climate targets, hopes for a global deal are rising.

A third cause for optimism is the reappraisal of climate-change economics. Five years ago, policies aimed at cutting greenhouse-gas emissions were seen as a cost burden on the economy. Negotiations were therefore a zero-sum game, with countries seeking to minimise their obligations while asking others to do more.

However, new evidence may be altering the economic calculus. According to research conducted by the Global Commission on the Economy and Climate, far from hurting the economy, well-designed climate policy may actually boost growth.

Chaired by former Mexican president Felipe Calderón and comprising former prime ministers, presidents, and finance ministers, the Commission is analysing how investments in clean-energy infrastructure, agricultural productivity, and urban transport could stimulate sluggish economies.

Its conclusions will be presented at September’s summit; if accepted, the Commission’s work could mark a turning point.

None of this guarantees success. Powerful vested interests, not least the world’s fossil fuel industries, will no doubt seek to limit progress, and most governments are not yet focused on the problem. But one thing is sure: Ihe reality of climate change is making it impossible to ignore.
