Dot Earth Blog: Technology as a Path to Product Transparency

Written By Unknown on Minggu, 29 Juni 2014 | 15.50

After I posted yesterday on Agriculture Secretary Tom Vilsack's push for using scannable codes to provide consumers with information on food ingredients from genetically modified crops, Ben Grossman-Cohen of the anti-poverty group Oxfam International sent a reaction that merits publication as a "Your Dot" contribution. 

In my piece, I wrote about the prospect that scannable codes can lead to far more background on products than simply the role of biotechnology in their production. I mentioned one of my favorite examples — the prospect of charting the origin of the tropical mangoes in a popular Belgian juice line. Grossman-Cohen discusses some noteworthy examples of online information portals, including one created by Oxfam, that can help inform consumers:

Secretary Vilsack is probably right to suggest that the future of labeling and transparency for food products is in some form of a bar code scanner. There are actually a number of groups like OpenLabel, GoodGuide and Buycott that are already exploring the world of apps that allow consumers to scan bar codes to find out what's in/behind the labels of the products they buy. Ultimately somebody will figure out how to do it really well. The main challenge seems to be figuring out how much information to include and then actually making the tools useful and user friendly. 

You mentioned your son's taste for Looza and wondered, "Where does the pulp come from? Are there good labor standards, sustainable farming practices?" Like most brands Looza is actually owned by one of of the giant food companies. These days, it's difficult to find products on our shelves that aren't. In this case I believe Looza is a Tropicana product and thus a subsidiary of PepsiCo. [He's right.]

A great existing resource to know whether PepsiCo/Tropicana are operating sustainably is Oxfam's interactive Behind the Brands rankings, which rate companies for how sustainable and responsible their corporate policies are. Looking at Tropicana's scores you'll see that our assessment of PepsiCo found that their policies on farmers and workers issues are "poor" while they get slightly higher marks for how they address their impacts on climate change and land. If you really want to dig into the details you can read through our massive open data sheet that shows how those scores were created.

It's not a perfect tool, but certainly gives a good overview of some of the key issues related to how the companies that own the brands we buy are operating. We are also exploring how to bring our data to consumers everywhere via a bar code scanner. In fact, the data behind our scorecard is already being used by a group called eLabel in their bar code scanning app for Woolworths customers in South Africa. Hopefully consumers everywhere will have that opportunity someday soon.

Dot Earth Blog: A Darker View of the Age of Us – the Anthropocene

Written By Unknown on Kamis, 19 Juni 2014 | 15.49

Are we no wiser than bacteria smeared on agar, even as scientists identify an edge to the Petri dish?

I alerted a batch of scholars and scientists focused on climate change and sustainable development to my taped talk on "Paths to a 'Good' Anthropocene" at the annual meeting of the Association for Environmental Studies and Sciences.

Clive Hamilton, a professor of public ethics at Australia's Charles Sturt University and the author of "Requiem for a Species: Why We Resist the Truth About Climate Change," reacted bluntly. Read on for his reply to the group, which he also posted on his blog, followed by an initial reply from me. I'm going to edit a version of the video that includes my slides and will weigh in at greater length when that's ready.

Here's Hamilton's critique, which doesn't deal with the core argument of my talk (the need for a shift in goals from numerical outcomes to societal qualities) and instead focuses on my use of the word "good" in relation to an era he clearly sees as awful:

Thanks for sending the link to your talk on "Charting Paths to a 'Good' Anthropocene." Since you ask for responses let me express my view bluntly. In short, I think those who argue for the "good Anthropocene" are unscientific and live in a fantasy world of their own construction.

If we listen to what Earth system scientists, including climate scientists, are telling us, the warming of the Earth due to human causes is a slowly unfolding catastrophe. We already have 2.4 degrees C. of warming locked in and, even under the most optimistic mitigation scenarios, it will be very hard to avoid 4 degrees C. by the end of this century.

According to those best placed to make projections, a world 4 degrees C. warmer would be a very different kind of planet, one unsympathetic to most forms of life, including human life. Apart from climatic change, other manifestations of human impact in the Anthropocene, from interference in the nitrogen cycle to plastics in the oceans, only add to the grim outlook.

The advocates of the "good Anthropocene" do not attempt to repudiate the mass of scientific evidence; instead they choose to reframe it. As you declare so disarmingly in your talk: "You can look at it and go 'Oh my God', or you can look at it and go 'Wow, what an amazing time to be alive!' I kind of choose the latter overall." You are, of course, entitled to put on any kind of glasses you choose, including rose-colored ones; but that does not change what you are looking at.

So it would make no difference if I took the time to document again what you and your fellow "eco-pragmatists" are looking at (the World Bank report is a pretty good overview). Unlike deniers who feel compelled to attack the science, advocates of the good Anthropocene just seem to glide over it.

You believe that "with work … we can have a successful journey this century…. We are going to do OK." Personally, when I think about those toiling, vulnerable masses who are going to suffer the worst consequences of a warming world, I find it offensive to hear a comfortable, white American say, "We are going to do OK." I'm sorry if this seems harsh, but unless the I.P.C.C. has it completely wrong, much of the world's population is not included in your "we."

The eco-pragmatists who embrace the new geological epoch – Michael Schellenberger, Ted Nordhaus, Peter Kareiva, Erle Ellis, Emma Marris, Stewart Brand, Mark Lynas – express an unbounded faith in technology and human ingenuity, and view the natural world as ultimately conformable to human manipulation and resilient enough to bounce back from whatever humans throw at it.

For them the Anthropocene is not proof of humankind's shortsightedness or rapacity, let alone the product of a power structure defended vigorously by fossil energy interests. There are no planetary boundaries that limit continued growth in human population and economic advance. Humans can adapt and prosper in a hotter world because history proves our flexibility. In this view, as we enter the Anthropocene the only barrier to a grand new era for humanity is self-doubt and the "pessimism" of gloomy scientists. Like you, Ellis, Kareiva and the Breakthrough crowd see the new epoch as "an amazing opportunity," humanity's transition to a higher level of planetary significance.

It is not surprising that the eco-pragmatists attract support from conservatives who have doggedly resisted all measures to cut greenhouse gas emissions, defended the interests of fossil fuel corporations, and in some cases worked hard to trash climate science. These are the same people now drawn to geoengineering, especially solar radiation management, as a substitute for reducing emissions. For them, resorting to geoengineering justifies and entrenches the prevailing system, which is their overriding goal.

So the "good Anthropocene" is a story about the world that could have been written by the powerful interests that have got us into this mess and who are fighting so effectively to prevent us from getting out of it. In the long term this kind of thinking will prove more insidious than climate science denial.

If, against all the evidence, the eco-pragmatists choose to say "What an amazing time to be alive" we can understand the choice as a kind of coping strategy. Those who cope this way acknowledge and accept the facts about global warming up to a point, but they blunt the emotional meaning of the facts. But it is a maladaptive coping strategy, one that provides a balm for feelings of anxiety, fear and helplessness, yet impedes the appropriate action.

Many among the general public cope with global warming by "de-problematising" the threat using inner narratives such as "Humans have solved these sorts of problems before" and "Technology will always provide a solution." The eco-pragmatists provide an intellectual justification for this kind of wishful thinking. Tacking "good" onto "Anthropocene" may be an effective emotional reframing, but it is without scientific foundation.

It has been shown that humans can benefit from what psychologist Shelley Taylor calls "benign fictions", unrealistic stories about ourselves and the world that lead us to predict what we would prefer to see, rather than what is objectively most likely to happen. Yet these healthy illusions that can spur us on against the odds can become dangerous delusions when they continue to be held despite evidence from the outside world telling us we must change course.

In the end, grasping at delusions like "the good Anthropocene" is a failure of courage, courage to face the facts. The power of positive thinking can't turn malignant tumors into benign growths, and it can't turn planetary overreach into endless lifestyle improvements. Declaring oneself to be an optimist is often used as a means of gaining the moral upper hand: "Things may look bad but, O ye of little faith, be bold and cheerful like me."

Things are bad, and if we carry on as we are things will be very bad. It is the possibility of preventing bad turning into very bad that motivates many of us to work harder than ever. But pretending that bad can be turned into good with a large dose of positive thinking is, even more so than denying things are bad, a sure-fire way of ending up in a situation that is very bad indeed.

This was my initial e-mailed reply to Hamilton and the copied group (with shorthand tidied in a couple of spots):

Great input. What you take as conscious "framing," to me is much deeper than that (see Kahan et al's "cultural cognition" work; think about McKibben and Monbiot's reactions to Fukushima as another example).

I actually think we are in line on the importance — the primacy in fact — of limiting impacts form climate-related extremes on the world's poorest. I've made that point that that needs to be disconnected from work on emissions mitigation because the drivers of that vulnerability are far faster than climate change itself.

See my piece on the 2009 Shanahan et al paper as one example: "Debate Over Climate Risks – Natural or Not."

On your other points, too, I think there's more commonality than you infer. I've never embraced geo-engineering (except for work on enhanced air capture of CO2 as a long-haul imperative). I've written that it's unlikely we'll ever see solar-radiation management because no one will ever agree where to se the thermostat and no country will have such a direct national interest that it will proceed unilaterally.

See "Who Gets to Set the Global Thermostat?"

There's much more to say. For instance, I reject Hamilton's assertion that I'm expressing "an unbounded faith in technology and human ingenuity." I've actually expressly rejected that simple techno-fixes will win the day.

I also trust that while Hamilton and those who championed his view on Twitter clearly dislike the notion of a "good" Anthropocene, that doesn't mean they're hoping for a "bad" one. [Line added, 2:00 p.m.]

In the end, I think the best starting point remains the talk, with the slides. Stay tuned. If you can't wait, watch the barebones version here:

Dot Earth Blog: Roundup: Can New E.P.A. CO2 Rules Have a Climate Impact?

Written By Unknown on Minggu, 08 Juni 2014 | 15.50

A prime challenge in trying to limit the human influence on the climate is that the atmosphere is a commons. One country's actions limiting greenhouse gas emissions can be rendered moot if others don't act, as well.

With that in mind, Fuzz Hogan, the managing editor at the New America Foundation, invited me to weigh in with others on this question about President Obama's proposed "Clean Power Plan" — the first American regulations restricting carbon dioxide emissions from existing power plants:

Will the new E.P.A. standards mean that a meaningfully greater volume of hydrocarbons will stay in the Earth forever? If not, why not? If so, how? Or are we asking too much of some regulations passed in the second-term of a Presidency gummed up by sclerotic politics?

Visit the foundation's Weekly Wonk blog for answers from Sharon E. Burke, an international and energy security analyst, Steve LeVine of Quartz, Daniel Sarewitz, professor of science and society at Arizona State University, and Russell Gold, senior energy reporter at the Wall Street Journal and author of "The Boom: How Fracking Ignited the American Energy Revolution and Changed the World."

To prime the pump, here's my riff: 

The move by the Obama administration is mostly doing what's possible, not what's needed given global emissions trends for carbon dioxide, but is still creditable given the lack of such a step under previous administrations. Will it meaningfully limit how much ancient carbon is liberated before the world transitions fully to a non-polluting energy menu? I'd say no. There's a lot of mostly wishful talk about the potential impact of the E.P.A. power plant rules on international treaty talks this year and next.

It's wishful because the real-time imperative of expanding energy access in rapidly developing countries — notably China and India but also those further down the development chain — will for many years to come trump long-term concerns about limiting the greenhouse-gas buildup. And, if anything, these countries are more insistent than ever (see China's stance discussed here) that the heavy lifting, not marginal Obama-style cuts, needs to be done (or somehow paid for) by the world's established powers, which built their prosperity on decades of unrestrained coal and oil combustion.

Please read the New America roundup. Also read Paul Krugman's latest column, "The Climate Domino." He's more bullish than I am on the idea that China can be prodded to act through American action.

Dot Earth Blog: Behind the Mask – A Reality Check on China’s Plans for a Carbon Cap

Written By Unknown on Kamis, 05 Juni 2014 | 15.50

BEIJING — Having covered China's stance on global warming since 1988, I've gotten attuned to the need to tread carefully when something is said that feels like a shift in the official position of this greenhouse gas giant.

The ancient Chinese mask-changing dance that I saw here Tuesday night (at a dinner for participants in a meeting on science and sustainable development) came to mind in considering the unraveling of news a few hours earlier of an official Chinese plan for a firm cap on emissions of carbon dioxide, hard on the heels of President Obama's proposed carbon pollution rules for existing American power plants.

Here's how things played out. An adviser to the Chinese government on climate change was quoted by Reuters as saying the following at a Beijing climate-policy conference on Tuesday:

The government will use two ways to control CO2 emissions in the next five-year plan, by intensity and an absolute cap.

The comment came from He Jiankun, a professor at Tsinghua University and deputy director of China's Expert Committee on Climate Change, speaking at an international forum on market mechanisms for low-carbon development sponsored by Tsinghua and Harvard University.

The story quickly pivoted to how significant this would be given the context of President Obama's move and informal climate talks starting on Wednesday in Bonn, Germany, aimed at setting the stage for fresh climate treaty work later this year at the United Nations and in Lima, Peru.

The Guardian quickly followed Reuters with "China pledges to limit carbon emissions for first time," a piece canvassing climate campaigners but offering no reinforcing input from the Chinese government.

I consulted with The Times's Beijng bureau. Christopher Buckley, a reporter [based in Hong Kong] who in 2011 had covered China's emissions plans [and similar pushes from advisers to adopt a cap] while with Reuters, spoke with He Jiankun, who told him repeatedly that he did not in any way speak for the government, or the full expert climate committee.

Here's Buckley's translation: 

It's not the case that the Chinese government has made any decision. This is a suggestion from experts, because now they are exploring how emissions can be controlled in the 13th Five Year Plan…. This is a view of experts; that's not saying it's the government's. I'm not a government official and I don't represent the government.

A Reuters reporter told me tonight that a correction was being posted [it's here], but not before other newspapers – including USA Today with a piece on China's "emissions pledge" – built on the report.

Other, more recent news coverage has reflected that this isn't China's position, although many experts in Beijing (including at the meeting I'm participating in) foresee an eventual cap and a peak in China's emissions sometime after 2030.

Here's more from other news outlets. The China News Service, a state-run news agency, also reported on the comments made by Professor He at the Tsinghua-Harvard forum but made no mention of proposals for a quantitative cap on carbon dioxide emissions.

The Financial Times posted "China climate adviser urges emissions cap."

Recalling that all energy forecasts need to be treated with a healthy dose of skepticism, best guesses for a peak in China's greenhouse gas emissions tend to center on the 2030s, as reflected in this paper earlier this year in the journal Energy Policy: "Peak energy consumption and CO2 emissions in China."

Here's the abstract:

China is in the processes of rapid industrialization and urbanization. Based on the Kaya identity [a formula drawing on economic activity, energy use and other factors to determine a country's greenhouse-gas impact], this paper proposes an analytical framework for various energy scenarios that explicitly simulates China׳s economic development, with a prospective consideration on the impacts of urbanization and income distribution. With the framework, China׳s 2050 energy consumption and associated CO2 reduction scenarios are constructed. Main findings are: (1) energy consumption will peak at 5200–5400 million tons coal equivalent (Mtce) in 2035–2040; (2) CO2 emissions will peak at 9200–9400milliontons (Mt) in 2030–2035, whilst it can be potentially reduced by 200–300Mt; (3) China׳s per capita energy consumption and per capita CO2 emission are projected to peak at 4tce and 6.8t respectively in 2020–2030, soon after China steps into the high income group.

Things could potentially speed up, as some have noted, but there are limits to the pace at which China can develop enough cleaner energy alternatives to cut back on coal burning. Professor He noted this in the Reuters article:

He said China's greenhouse gas emissions would only peak in 2030, at around 11 billion tonnes of CO2-equivalent. Its emissions currently stand at around 7-9.5 billion tonnes. But He said that would depend on China achieving a real reduction in coal consumption from sometime around 2020 or 2025, and on the nation meeting its target of having 150-200 gigawatts of nuclear power capacity by 2030. The share of non-fossil fuels in China's energy mix would reach 20 to 25 percent in 2030, He added.

Once an emissions peak and rough timeline are clearer, you can be sure a cap will be announced — but only when the trajectories are already in place to make it a sure bet.

We're already locked in for substantial human-driven climate change, but the intensifying focus on a post-fossil future in both China and the United States points to a real prospect that much of the world's remaining coal will stay in the ground in the end.

Addendum | To get a clearer view of China's stance on who needs to do what, and when, on CO2 emissions, click back to my interview last fall with Zou Ji, the deputy director of China's National Center for Climate Change Strategy:
