Meet the Change Makers: Tiffany’s Diamonds and Gold Get Greenish Sparkle With Stance Against Pebble Mine | OnEarth

Most businesses hungrily pursue new sources of vital raw materials. Tiffany & Co., by contrast, has begun to forge a different path. In the last several years, the company has taken an increasingly public and vocal stand against an enormous gold mine that has been proposed at the headwaters of Bristol Bay, Alaska. Pebble Mine, as the project is known, is estimated to hold more than $300 billion worth of gold ore and other precious metals.

Publicly listed Tiffany & Co. traces its roots back to 1837, when Charles Lewis Tiffany and John Young set up a “stationery and fancy goods emporium” in New York City. Today, with $3.1 billion in sales last year, the storied jeweler has a very big appetite for gold, diamonds, and similar earth-borne treasures. Yet Tiffany CEO and chairman Michael J. Kowalski sees the near-term costs of squelching a new gold supply as far outweighed by Pebble Mine’s potential risk to the environmental, and in turn, to Tiffany’s brand.

The proposed mine lies within a 40,000-square-mile watershed, filigreed by dozens of pristine rivers and tributaries, that is home to beavers, moose, and caribou, which feed off summertime plant growth. A huge population of bears, as well as the native Yupik people, relies on the annual return of spawning sockeye salmon, a flood of wild fish that ranks among of the world’s largest such runs. Opponents argue the fishery — worth hundreds of millions of dollars a year — and the broader ecosystem could be imperiled by mine construction and runoff of acids and dissolved metals. “I can’t think of a mine that threatens more ecological value in North America than Pebble,” Kowalski said.

Tiffany’s take on mining issues has evolved over a two-decade span that roughly coincides with Kowalski’s tenure, during which time the company has faced the overlapping crises of blood diamonds and conflict gold. Mining practices in strife- and famine-torn regions have led to grievous human rights abuses, as warring factions fight for access to mineral wealth, as well as environmental damage, such as mercury pollution from small-scale gold-mining operations. Today, the company states flatly that, with respect to mining: “We recognize that some public lands are simply not suitable for mining, and that their value for recreation and conservation is far greater than their value as a source of minerals.”

Tiffany’s increasingly visible commitment to sustainability is documented in its first corporate sustainability report, released last month. In addition to advocating for responsible mining, the company has also focused on its retail operations — manufacturing its iconic blue boxes and bags, for instance, exclusively from materials certified by the Forest Stewardship Council. Efficiency upgrades and solar panels in its stores have lowered greenhouse gas emissions by more than nine percent per square foot since 2006.

OnEarth contributor Adam Aston recently discussed Tiffany’s evolving approach to sustainability with Kowalski at his office — decorated with photographs of family travels to national parks in the United States and overseas — at the company’s Fifth Avenue headquarters in midtown Manhattan.

Tiffany & Co. depends on mining, yet mining is destructive by nature. How do you decide one proposed project is promising, but another, like Pebble, is not?

It’s difficult for us to make definitive statements about what constitutes responsible mining today. But in a simplistic sense, we’re clear that it’s better to extract minerals from a legacy mine than to threaten a pristine ecosystem. That led us to Rio Tinto’s Bingham Canyon Mineoutside of Salt Lake City. The precious metals used in our U.S. manufacturing come from there as well as from recycled sources.

The mine has been there for 100 years. There are legacy issues, certainly, but today the mine is being managed responsibly. I know Mr. Redford would disagree [Ed. note: Writing for OnEarth’s Community Blog, NRDC Trustee Robert Redford has compared the threat of the proposed Pebble Mine to the environmental damage done by Bingham Canyon Mine]. But it is a worthwhile debate.

Look, we all may not be pleased with the standard of U.S. environmental regulations for mining, but they are pretty good in a global context. The greater concern is mines in less-regulated areas. Isn’t the more positive thing to source from a nearby mine that is monitored than from one that is far away, where we have no influence, and regulations are practically nonexistent, such as in, say, Papua New Guinea?

For those reasons, some have suggested that Pebble Mine would operate using the world’s best practices, including regulation and monitoring.

The argument has been made: “Well, if you really care about responsible mining, you should be a supporter of Pebble because it will be the most responsibly built and managed mine in the history of mining, and it is unfair to tar Pebble with the abuses of past mining practices.” In fairness to the Pebble Partnership (a joint venture between a subsidiary of Anglo Americanand Northern Dynasty Minerals), I want to make this clear: We have no doubt that they would do everything possible to develop that mine as responsibly as they possibly can. And I’m going to presume that the state of Alaska will do everything possible to make certain that happens if the mine goes forward.

That said, we have reached the conclusion — as have many non-governmental organizations (NGOs) and local Alaska residents — that the risk is simply too great. Despite the best of intentions, the location of this mine is so inherently problematic that it is simply not worth the risk of a catastrophic event. Other jewelers have come to the same conclusion and, like us, signed The Bristol Bay Protection pledge.

Is this is first such position you’ve taken on gold mining?

No. Starting back around 1994, we began receiving a fair amount of unsolicited mail asking us to oppose the New World gold mine that was planned right outside of Yellowstone National Park. At that point, we didn’t have the ability to see into our gold or silver supply chain, nor had our company policy on these issues been developed.

We began making inquiries, and as we learned more we thought, “If the New World mine is built, and there’s a catastrophic failure of the tailings dam, the flood would destroy a good part of Yellowstone National Park. That’s not a good thing for the jewelry industry.” It was that simple. We drew the conclusion that, as leaders of the jewelry industry — not necessarily by size but certainly by reputation — it was appropriate for us to speak out in opposition.

When did you begin to formalize your mining policies?

About 10 years ago, we began to see concerns about gold mining enter the mainstream media. So around 2001, we started making inquiries to the NGO community, saying, “We’re very interested in responsibly mined metals, but what should we do?” The response shocked us because, back then, a lot of NGOs said, “There are no standards of responsible mining yet. We really can’t tell you where to go.”

In 2002, we began working with NGOs like Earthworks to move forward on this issue. Today we abide by a set of core principles around responsible development and operation of large-scale mines.

Tiffany is synonymous with diamonds. How did the crisis of blood diamonds influence your position on mining?

Our experience with blood diamonds certainly raised our awareness about the environmental and human rights risks connected to metal mining. They weren’t remotely on our radar screen when the stories first surfaced. That’s because, back in in the early ’80s, we did not manufacture the majority of our jewelry. We bought it from manufacturers around the world, primarily from Europe, and some from the U.S. We would also buy polished diamonds — not rough unfinished diamonds — from diamantaires* in historic diamond centers such as New York, Tel Aviv, or Antwerp. Because of this arrangement, we had little insight into the supply chain beyond those levels, and quite frankly, little incentive to make needed improvements to our supply practices. [*Ed. note: Diamantaire is an industry term, describing buyers, traders, and artisans who work in the middle layer of the supply chain. Diamantaires buy, cut and polish raw diamonds before they’re set into jewelry to sell to larger wholesalers or retail jewelers.]

So dependency on diamantaires left you with little control over the origin of the gems?

Yes. Then, in essence, we became our own diamantaires. We had also undertaken a separate effort to vertically integrate our supply chain, beginning some years before the blood diamond problem first surfaced. The company was growing rapidly, and we needed to assure the flow of supply of manufactured goods, and later raw materials. We committed to cutting and polishing our own diamonds so that we could buy rough diamonds at the mine head. That gave us better knowledge of where a particular diamond came from.

The horrors of Sierra Leone crystallized this part of the strategy. We knew we absolutely had to be able to identify the country of origin and, ultimately, the mine of origin of as much of our raw materials as we could.

It’s an ongoing process. We’re not all the way there, even today. But we’re confident that over time, for diamonds, we can identify the mine of origin, and attest to the social and environmental conditions at those mine sites.

Many industries have abandoned such vertical integration, arguing that high-volume specialists can be more efficient. How has taking control over your manufacturing process affected your bottom line?

By streamlining the supply chain, we have been able to capture a greater share of the profits typically taken at each step, from mine to trader, from trader to polisher, and so on. The vertical integration has been a strong profit-driver, and it’s also allowed us to try to exercise some leadership on corporate social responsibility issues around the supply chain. For example, we have invested heavily in places like Botswana and Namibia to train diamond setters and polishers. By investing in those communities, we’ve helped create industries that deliver more income than the simple extraction of gems could alone.

We’re probably rather unique, I think, for a retailer. We are without a doubt the most vertically integrated retail jeweler in the world. We make about 65 percent of all our jewelry at facilities here in the U.S., at a site in Westchester County, New York, and another in Providence, Rhode Island. This includes the jewelry we sell around the world — in fact, we’re a net exporter, even to China.

Other industries have established standards — I’m thinking of industry-created definitions of “organic” in the food business. Tiffany has been outspoken about the need for third-party standards for responsible mining. What progress are you making?

We very much believe that if there are to be standards for human rights and environmental practices in the jewelry industry, there must be genuine third-party certification, where NGOs and other stakeholders participate in the establishment of those standards. You saw this with blood diamonds. I think the industry rallied dramatically to correct the problem by creating theKimberley Process [to certify rough diamonds as conflict-free], which I think has largely been a success.

We have every control in place to be certain that diamonds from Tiffany only have Kimberley certificates. Can I make a 100 percent affirmative claim that nothing here has every come through? No one can. And that is, I think, where some of the biggest challenges are, in trying to assure supply chain integrity.

Does this position create tension with the mining industry?

We take great umbrage at criticisms we’ve faced. Some of the pro-mining folks have said of our efforts, “This is all about public relations.” In response, I say, “Hold on. We’ve been concerned about this for almost 20 years. This is not about greenwashing. This is something we’ve been committed to. It’s what our customers want. It’s about the business imperative.”

In fact, we’re pro-responsible mining because we think that’s what is essential for the growth and long-term economic health of the jewelry industry.


TRUTH SQUAD — Checking industry claims with NRDC’s sustainability experts

The prestige of Tiffany’s brand means there is real force behind the company’s efforts to reshape the way jewelry retailers and the broader mining industry are approaching sustainability, says Joel Reynolds of the Natural Resources Defense Council, who directs its urban west program and the marine mammal protection and Southern California ecosystem projects. He also leads the Save Bristol Bay campaign, bringing together a broad coalition of interests opposing the proposed Pebble Mine in Bristol Bay, Alaska. In particular, he says, “Tiffany has a unique ability to draw attention to [Pebble Mine].”

As Tiffany turned up the volume on the issue, other major retailers such as Walmart and Target — which sell high volumes of lower-cost gems, gold and other jewelry — have taken notice, says Reynolds. This is leading to a process that he believes will improve industry practices and lead other major jewelry retailers to sign on to the The Bristol Bay Protection pledge, as Tiffany has done. At the core of the issue, Reynolds said, is the question of whether the mine can be built and operated without significant risk. “Under comparable hydrological circumstances, 93 percent of similar mines in the U.S. have failed to meet the standards they commit to in their original environmental impact assessments,” he notes, pointing to a 2006 study of water-quality problems at hard-rock mines.

Key state and federal deadlines for Pebble’s developers to submit permit applications for the mine were originally set for this year, but have been pushed back to 2012 and 2013. This suggests opposition to the project is getting traction, Reynolds says. Outside Alaska, the mining reform organization EarthWorks has successfully lobbied more than 60 jewelers to take the “No Dirty Gold” pledge, which would apply to the Pebble Mine. Tiffany & Co. is a long-time signatory. Target is the most recent retailer to sign on, in March of this year.

By taking this voluntary pledge, jewelers agree to abide by The Golden Rules of responsible mining: to ensure that toxins, such as sulfuric acid, don’t contaminate the land, water, and air, and that workers rights and labor standards are respected. Still, critics charge that until a third-party certification system for gold mining exists, efforts to clean up the industry will remain piecemeal and difficult to verify. — Adam Aston

Challenging a Landmark Theory of Biodiversity | environment:YALE

By Adam Aston

What does a court full of towering collegiate basketball players have in common with a forest full of vertiginous trees?

For legions of basketball fans, the answer may not go beyond height. But for ecologists who study species dynamics, the answer promises to alter our understanding of the success of species. It could also help better guide how conservation is practiced in an era of fast-multiplying extinctions.

In a study published on March 9 in PLoS ONE, a team of four ecologists at F&ES outlined a connection between basketball and ecology that is, at first glance, deceptively simple. They concluded that the pattern of wins and losses by basketball teams is essentially identical to how species flourish or fail in nature.

Straightforward as these similar distribution patterns may seem, the findings bring into question a landmark theory of species dynamics known as the unified neutral theory of biodiversity.

Developed in recent decades, neutral theory offers ecologists a tantalizingly powerful tool. As a statistical approach, it suggests that for any species—from trees to fish to microbes—patterns of diversity can be modeled solely on the basis of random fluctuations in births, deaths and new arrivals of species rather than on particular traits.

For many ecologists, the implications are jarring. By this reasoning, competitive aspects—whether drought tolerance in trees or poisonous glands in frogs—have little to do with a species’ long-term success relative to its competitors.

As a test of neutral theory, however, the basketball study proves otherwise, says Robert Warren, lead author of the study and a postdoctoral researcher at F&ES. “Some scientists say that the theory of survival of the fittest predicts which species are abundant; some say it is just random,” says Warren.

Scientists cannot assume that because “a mathematical model is simple, the underlying processes are simple,” says Warren. “This assumption is where unified neutral theory becomes problematic.”

To understand the allure of the neutral theory of biodiversity, it’s helpful to take a step back. Compared with physics or math, ecology has relatively few grand unified theories—as yet, there’s no E = MC2 to describe species dynamics.

Unlike more theoretical, mathematical sciences or experiment-based laboratory studies, field biology is messy. Collecting observational data on flora and fauna in their habitats is painstaking. And the data sets from studying trees for decades, for example, are relatively small.

The upshot is that sweeping laws are notoriously difficult to make foolproof in ecology and, so, are rare.

The best-known example of such an insight is, of course, Charles Darwin’s quest to develop and refine his theories of natural selection to explain the process and history of the evolution of species that he observed in a mix of living animals and related fossil records.

In 1859, following decades of observation, he noted that “… rarity is the attribute of vast numbers of species in all classes …” in his landmark On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.

That’s why, in 2001, when ecologist Stephen Hubbell published a statistical explanation of the diversity and relative abundance of species in ecological communities, it caused such a stir.

Using statistical methods to assess tree populations in a tropical forest, Hubbell suggested that biodiversity derives from randomness more than from species-by-species attributes.

Put another way, variables such as species dominance, food supply, climate or competition can be treated as neutral, or ignored, in predicting a species’ success. For its methodological elegance, Hubbell’s 2001 book, The Unified Neutral Theory of Biodiversity and Biogeography, changed the paradigm for the way ecologists modeled ecosystems.

“It had long been assumed that competition and the theory of survival of the fittest created the diversity patterns observed in nature as species evolved unique niches to coexist,” says Warren. “Then unified neutral theory came along; it could explain species abundance as well, or better, than competition models.”

The theory set up a troubling dilemma, however, fueling a debate that has simmered ever since. As correct as the math of Hubbell’s unified neutral theory may be, it suggests that factors ecologists had long toiled to map and understand didn’t matter in the success or failure of a given species.

Ecology is a field where careers can be spent—as Darwin did sailing the seas—in remote study, meticulously assessing the effects of geography, environment or competitors on species. Against this backdrop, the implication of unified neutral theory suggests that, on average, none of these factors matter much more than any other—i.e., they are all neutral.

And while Hubbell didn’t necessarily intend for his study to guide conservation thinking, it nevertheless has big implications there, too.

On one hand, it offered a new tool: since unified theory mathematically combines the study of species abundance and biogeography—or how the distribution of organisms relates to the Earth’s physical features—it offers conservationists a tool to guide the sizing of reserves to harbor the greatest diversity of species.

But on the other hand, if competitive factors are truly neutral, then decisions made by conservation biologists about how best to protect a struggling species could easily be off target or even, at worst, a waste of time and money.

“Neutral theory would say just roll your dice,” says Oswald Schmitz, a co-author and Oastler Professor of Population and Community Ecology at F&ES. “But if there are rules about how species associate themselves on the landscape and there are mechanisms behind the rules, then that has very different management implications than a neutral-theory approach.”

At the middle of this scientific tug of war is the question of randomness.

To model species abundance and distribution, unified neutral theory assumes that the mechanisms that guide success or failure have no pattern.

Yet for Warren and other ecologists who disagree, it’s a vexing challenge to disprove, because identifying the mechanisms that affect a species’ success is so devilishly difficult.

A population of frog species, for example, could grow one year because of good rains but ebb in similar conditions another year because of a blight or the shift to a new region as a result of land use changes. Simply identifying the vast number of mechanisms affecting the frogs’ numbers is a challenge.

Connecting these interrelated factors with effects is even trickier.

What if, Warren wondered, one could identify a population whose mechanisms of competition are well-understood and which also generated population dynamics consistent with neutral-theory methods?

This would prove, a priori, that mechanisms are not neutral. If mechanisms do matter, unified neutral theory would still be useful in describing population dynamics at a high level, but it would be inappropriate to use the theory to devalue the close study of ecological mechanisms in the field.

Enter the basketball test. A native of Indiana, home of Larry Bird and arguably the most basketball-crazed state, Warren considers himself a die-hard basketball fan. The idea for the study came to him one day in North Carolina’s Appalachian mountains, while he was counting seed-carrying ants as part of his research on herbaceous forest plants. Warren realized that the pattern of basketball wins is similar to the distribution curves that underpin unified neutral theory.

Warren isn’t the first ecologist to look to examples beyond biology to test aspects of neutral theory. Other researchers have identified even more eclectic sample groups where much is understood about the underlying dynamics. Stock prices, the occurrence of scientific citations and even set lists for the Cowboy Junkies have all been used to generate species abundance distributions, a core piece of evidence for neutral theory.

Basketball seemed like a particularly ripe prospect to Warren. What you’d need, he figured, is lots of species, and there are hundreds of basketball teams. In his approach, each team is analogous to a species, with each of their wins counting as an individual being born. Losses, therefore, are akin to an individual dying. And because basketball teams play many games each year, over many years, the resulting data set is big enough for solid statistical analysis.

Most of all, though, basketball makes an apt case, because the underlying mechanisms of success and failure are so well-understood by so many. As even casual fans can attest, winning in a season or over many years comes from a combination of strategies. Among dominant teams—such as Duke, North Carolina, UCLA, or this season’s winner, Connecticut—some combination of great coaching and strong recruiting, among other factors, has led to long runs of dominance.

For the statistical trial, Warren crunched won-lost records from 327 NCAA Division I men’s basketball teams, a pool of data covering some 20,000 games spanning 2004 through 2008. It may come as no surprise that, across so many games, the most competitive teams generated many more individuals, or wins.

As he suspected, Warren found that his data pool of winning basketball species produced abundance distributions pretty much identical to those observed in countless ecological communities. For most teams, wins are rare, but for a few they are very common.

In short, if basketball wins are not random, then neither is species success. Conversely, if the logic of unified neutral theory were applied to basketball, “then our findings would suggest that the top seed in the tournament is no more likely to win than the last seed in each bracket,” says Mark Bradford, a co-author and assistant professor of terrestrial ecosystem ecology at F&ES. “We know that’s not true.”

For ecology writ large, the implication of the basketball study isn’t to disprove neutral theory. The study does knock out a cornerstone piece of

evidence, though, says Warren: “We show that a community, in this case college basketball—which is undoubtedly structured by competition—appears random when current methods for assessing biodiversity are used.”

Understanding what drives these dynamics is critical to both explaining species distribution today and guiding species conservation policy.

Reflecting on decades spent studying amphibian ecosystems—searching for causes of an ongoing population decline in frog, toad and related species— Dave Skelly, a co-author and professor of ecology at F&ES, acknowledged that the drive to infer process from pattern is one of science’s greatest animating forces.

Yet that search shouldn’t take away from on-the-ground study of mechanisms affecting species diversity. The hunt for a culprit in amphibian decline, for example, has led researchers to multiple causes. In the tropics, the chief culprit is a fungus. But in North America, most amphibians are immune to the fungus. Here, habitat loss is the greater threat.

“The upshot is that if you tried to ascribe a single cause to all this, you’d get it right in one environment, but dreadfully wrong in others,” says Skelly.

For conservation practices, the stakes for finding the balance are getting higher. In addition to fitting mathematical models to broad biodiversity patterns, “we need to put on our boots and head back to the woods to figure out why some species are common and so many are uncommon,” says Warren.

“Otherwise, we may find ourselves unable to manage species in the face of global environmental change.”

Book review – “The World Without Us” By Alan Weisman | BusinessWeek

Save The Planet: Disappear — Weisman presents a curiously refreshing vision of the apocalypse

THE WORLD WITHOUT US By Alan Weisman. Thomas Dunne Books/St. Martin’s Press — 324pp — $24.95

The extinction of humankind is a grim topic. Yet in The World Without Us, journalist Alan Weisman invokes this ancient specter as the jumping-off point for a refreshing, and oddly hopeful, look at the fate of the environment. His central question: What would earth be like if humanity just vanished? Weisman’s answer is as fascinating as it is surprising. It turns out, from towering bridges to sprawling cities–not to mention delicate books or masterly artworks–precious few of man’s creations would last long. The author richly documents the damage done by industrial civilization, providing further momentum for business to go green. But his explanation of just how all of our methodically built cities, factories, and temples would implode under the slow assault of rot, rain, plants, and critters is the most compelling aspect of the book. The winners in Weisman’s tour de décomposition are the very flora and fauna that today are under pitiless assault from humanity…
