On September 9, the Oregonian headlined its Sunday edition with a story about the Greenland ice sheet melting much faster than scientists had predicted. The well-crafted story found the news "...particularly unsettling because elaborate climate models that scientists use to estimate the effects of global warming did not foresee it."
While many scientists had been warning that such acceleration could be underway and that we were entering unchartered waters, it's true that recent observations on different kinds of ice loss have not yet worked their way into global peer-reviewed models. Such is the nature of peer-reviewed science and the hazards in communicating such complexities.
The good news about stories like this -- if there's good to be had in such dismal news -- is

Roger Ebert, film critic for the Chicago Tribune, once pointed to the criterion that often separates high-impact movies from those forgotten with the last handful of popcorn: do you care about the characters?
Recently, that simple question helped explain why my recent trip to China carried such impact.
Like others, I've often cited facts and figures surrounding China's economic growth to underscore the global imperatives for moving to a sustainable economy. China's economy is doubling every eight years, boosting consumerism to levels that are rattling markets around the world.
It has set ambitious goals for efficiency and renewables, though it is building a new coal-fired power plant every week. Half the world's new buildings between now and 2015 will be built

Christine Ervin, former U.S. Assistant Secretary of Energy, former president of the U.S. Green Building Council, recently joined Greener World Media as Editor at Large. As an introduction to her background, she sat down with Greener World Media's managing editor, Matthew Wheeland, on June 1 for a discussion about her take on the past, present and future of all things green.
Matthew Wheeland: You've been active in the green energy and green building worlds for some time now. But how did you actually get started?
Christine Ervin: I can trace my interest in clean energy to the moment that I read this amazing sentence from the Economist magazine back in the early '90s. It went something like this -- actually, it went exactly like this: "The production and use of energy causes

Having spent five years at the helm of the U.S. Green Building Council, the organization that created the LEED green building rating system, I've been getting a lot of questions lately about new pressures being faced by this green building standard. First, a savvy Web-based green assessment tool called Green Globes has been introduced in the U.S. as the first real competition to LEED. Next, two green building enthusiasts have issued a fiery plea for major overhauls to a "broken" LEED.
Do these developments pose a serious threat to LEED? Let's take a look.
Green Globes enters the market. Billed as the industry's first interactive, Web-based environmental assessment protocol, Green Globes was launched in Canada in 2002 and licensed for release in the U.S. earlier this year

Having spent most of my career working to advance green technologies, I'm hardly a Luddite. But it's the human side of technology -- from design to market conditions -- that largely determines its impact.
In the case of climate change, a cap is simply fundamental to creating an emissions trading market, which, in turn, provides the best climate for innovative technologies. No wonder so many corporate executives are calling for a national cap sooner rather than later; they see it as vital to lowering costs, increasing flexibility and giving us more room to maneuver under rapidly changing conditions.
The conundrum over caps brought back a conversation I had years ago with Ambassador Richard Benedick, lead U.S. negotiator and architect of the Montreal Protocol to protect ozone, when we worked at the World Wildlife Fund/Conservation Foundation. Given his vast experience and European roots, I had asked him why the U.S. lagged behind Europe on sustainability and he responded: "We ran up against physical constraints in Europe long ago. Until Americans come to accept the concept of limits, we'll never embrace sustainability."
It's true that Americans have a tortured history of chafing at anything that constrains our private freedoms for the benefit of -- gasp -- the public good. In the transportation sector, just look at the contentious history of highway speed limits, seat belts, CAFÉ standards and cameras to catch speeders. In the buildings sector, 10 states don't even have energy codes while many others lag far behind accepted standards that would clearly save money and pollution.
Not that I'm immune from reacting against constraints. At the 2006 Greenbuild in Denver, for example, I was delighted with the release of the "Living Building Challenge" from the Cascadia Region Green Building Council, the Pacific Northwest chapter of the U.S. Green Building Council. Here was a construct for thinking "beyond Platinum" -- a concept I was cool toward years ago when we were still building the LEED brand. But with so much experience in the market now, and the USGBC embarking on a next-generation LEED, surely the Living Building Challenge could inspire and stimulate.
Yet something nagged me about the Living Building byline: "No credits, just prerequisites," along with its one-tier, pass-fail structure. After all, it was LEED's flexibility that appealed to the building market through its light hand on prescriptions in favor of optional credits. And it was LEED's approachable four-tier system of certification that coaxed efforts from the mainstream market while engaging those on the leading edge. Savvy features like this go a long way to explain LEED's unprecedented impact in moving the market toward sustainability.
In short, LEED was not designed as an absolute definition of sustainability. That's why we sometimes hear complaints about LEED being "just a checklist" -— even though it's hardly LEED's fault if a building team chooses to use it like one. Many hundreds of high-performance, well-integrated buildings testify to its intended use.
On the other hand, it would be valuable to understand what the end game would look like for sustainability in any sector. That's the whole point of architect Bill McDonough's Cradle to Cradle framework. And oncologist Dr. Karl-Henrik Robèrt's The Natural Step (TNS) -- a set of "four system conditions" borne of a consensus process among Swedish scientist to identify requirements for a sustainable society. In the buildings arena, a group of industry professionals have actually created an overlay of TNS with LEED to use with projects and training programs.
The value of such absolute principles was abundant at last week's 10-year anniversary of the Oregon Natural Step Network (OTNS), a network credited with inspiring much of the sustainability leadership in the Portland region as well as multinational companies like IKEA, Skanska and Interface. From companies like NIKE to the Tualatin Water District, leaders cited benefits from having an absolute compass from which to gauge progress.
Some speakers also focused on the creativity unleashed by their self-imposed constraints. In particular, Ray Anderson offered tales of unexpected discoveries from climbing the Interface "Mountain of Sustainability" inspired by Paul Hawken and Dr. Robert. Challenged by exploring "how a forest would make a carpet," the resulting i2 carpet eliminates literally mountains of remnants and production waste by virtue of its non-directional design.
This kind of innovation is precisely what Janine Benyus, champion of biomimicry, meant by nature "tapping the power of limits" by using the limits of temperature, carrying capacity and energy balance as "source(s) of power."
And that's what the Living Building Challenge is doing by inviting a conversation on how absolute performance goals can yield "...buildings that are built to operate as elegantly and efficiently as a flower." Already, some designers like Clark Brockman, SERA Architects, are finding that they gain more intuitive design direction from striving to work within the Challenge's requirements.
What will sustainable buildings look like? We'll see early examples of projects and building elements at Greenbuild 2007's Member Day. And we'll start exploring how such constructs can complement LEED.
Americans may well chafe at limits, but the ecosystems we depend on for air, water, food, shelter, and beauty are governed by them. Such limits don't mean we need sacrifice that innate American can-do culture that comes from frontiers to be conquered -- on the contrary.
Just as we've admonished that true energy conservation is not about "shivering in the dark," it's time to embrace the abundance that can flow from nature's limits -- starting with caps on greenhouse gas emissions and moving toward a carbon-neutral built environment.
