Attention greenhouse gas emitters: There’s a new eye in the sky that will soon be photographing your carbon footprint and selling the images to any and all. It’s a micro-satellite dubbed “Claire” (clear, bright, and clean in French) by its Montreal-based developer, GHGSat. This microwave-oven-sized pollution paparazzo rocketed to a 512-kilometer-high orbit in mid-June care of the Indian Space Agency, with a mission to remotely measure the plumes of carbon dioxide and methane wafting up from myriad sources on Earth’s surface. Claire’s targets include power plants, natural gas fracking fields, rice paddies, and much more—just about any emissions source that someone with a checkbook (corporations, regulators, activists) wants tracked, according to GHGSat president Stéphane Germain.

One month after the terror attacks that traumatized Paris, the city has produced a climate agreement that is being hailed as a massive expression of hope. On Monday the U.K. Guardian dubbed the Paris Agreement, “the world’s greatest diplomatic success.” Distant observers may be tempted to discount such effusive language as hyperbole, yet there are reasons to be optimistic that last weekend’s climate deal finally sets the world on course towards decisive mutual action against global climate change. The birthing process clearly sets Paris apart from earlier efforts at global climate action, such as the Kyoto Protocol crafted in 1997. Only last-minute intervention by then U.S. Vice President Al Gore clinched a deal at Kyoto, and its impact faded as major polluters declined to ratify the treaty or dropped out. High-level diplomacy to secure a Paris deal, in contrast, began building in earnest last year with a bilateral climate agreement between U.S. President Barack Obama and China’s Xi Jinping—representing the largest climate polluters. Global buy-in grew over the following 12 months as one nation after another anted in with their own emissions reduction plans.
Three weeks before the start of the Paris climate talks, negotiators working to craft an international agreement to curb global greenhouse gas emissions are staring into a wide gulf between what countries are willing to do and what they need to do. Most countries have stepped up with pledges to meaningfully cut carbon emissions or to at least slow the growth of emission totals between 2020 and 2030. However, national commitments fall short of what’s needed to prevent the average global temperature in 2100 from being any more than 2 degrees Celsius warmer than at the start of this century—the international community’s consensus benchmark for climate impact. Worse still, national pledges employ a hodgepodge of accounting methods that include some significant loopholes that ignore important emissions such as leaking methane from U.S. oil and gas production and underreported coal emissions from China. How promised reductions will be verified post-Paris is “a big debate right now and it makes a massive difference in the numbers,” says Jennifer Morgan, global director for the climate program at the World Resources Institute, a Washington, D.C.-based non-governmental organization.
Chinese censors took down a hugely popular documentary on China’s air pollution crisis this past weekend, according to reports by the Wall Street Journal and the New York Times. Under the Dome, a polished, 104-minute report by Chinese broadcast journalist Chai Jing [embedded below], had gone viral after its release last week, attracting several hundred million views in China before censors restricted domestic access to the video and squelched news coverage of it.
The film is a damning account of China’s declining air quality, the sources of its pollution, and the toothlessness of environmental agencies charged with controlling it. It’s a wide-ranging production that tries to explain the price China has paid for its industrialization and wealth generation, as well as a passionate call to action.
For me, the film’s visceral portrayal of contemporary life amidst smog—and the movie’s historic sweep—sparked flashbacks to my own discomfort breathing in Chinese air during visits in 1991, 2005, and 2006.
In 1991, my eyes burned as the aging cruise liner I’d taken over from Japan motored up the Huangpu River, past the petrochemical plants then lining the river’s eastern banks, on its way into Shanghai. But the historic city across the river was clean. Aside from a few buses, it was a city that still moved on pollution-free pedal power, its streets a flood of bicycles. And as I traveled inland for several weeks, the pollution faded further, revealing China’s natural beauty.
When I flew into Shanghai 14 years later to report on China’s rising tide of electric bicycles for IEEE Spectrum, Shanghai itself seemed still cleaner than I’d recalled. While cars and trucks were on the rise, the East-bank industry had been cleared to make way for gleaming skyscrapers.
But China was clearly changing. I visited smaller cities where smog nearly blocked out the sun. Continue reading “Censors Take On China’s Silent Spring Moment”
I’ve delivered several dispatches on carbon capture and storage (CCS) recently, including a pictorial ‘how-it-works’ feature on the world’s first commercial CCS power for Technology Review. Two aspects of CCS technology and its potential applications bear further elaboration than was possible in that short text. Most critical is a longer-term view on how capturing carbon dioxide pollution from power plants (and other industrial CO2 sources) can serve to reduce atmospheric carbon dioxide concentrations. The Intergovernmental Panel on Climate Change is looking for CCS to do much more than just zero out emission from fossil fuel-fired power plants.

Context is everything in understanding the U.S.-China climate deal struck in Beijing by U.S. President Barack Obama and Chinese President Xi Jinping last week. The deal’s ambitions may fall short of what climate scientists called for in the latest entreaty from the Intergovernmental Panel on Climate Change, but its realpolitik is important.
Obama and Xi’s accord sets a new target for reductions in U.S. greenhouse gas emissions: 26-28 percent below 2005 levels by 2025. And for the first time sets a deadline for China’s rising GHGs to peak: 2030. This is potentially strong medicine for cooperation, when seen in the context of recent disappointments for global climate policy.

European leaders wrapped up a two-day climate summit in Brussels last week with a deal to cut the European Union’s total greenhouse gas emissions to 40 percent below 1990 levels. This would continue a downward trend – the EU is already on track to meet a 20 percent reduction from 1990 levels by 2020 – but the agreement is weak relative to Europe’s prior ambitions to confront climate change.
Investors in green tech pushed aggressively for the deal, seeking a longterm signal that the European market will continue to reward advances in energy efficiency and low-carbon energy production. The deal is also a shot in the arm for the Paris global climate talks, scheduled for December 2015, which will seek to achieve the decisive binding global targets for greenhouse gas reductions that failed to emerge from the 2009 Cophenhagen climate talks.
What the deal lacks is specificity and ambition regarding the mechanisms by which European countries are to achieve the carbon reduction. “Key aspects of the deal that will form a bargaining position for global climate talks in Paris next year were left vague or voluntary,” reported The Guardian.
