The Quiet Clean Mining Revolution

The Quiet Clean Mining Revolution
Few industries have got the black eye, literally and metaphorically, of mining. After centuries of environmental effects ranging from toxic emissions to unsightly tailings ponds, acid mine drainage, massive energy consumption and other impacts, mining is slowly cleaning up its act. Why? Mostly because new clean technologies are increasing industrial efficiencies. They’re lowering mining companies’ power needs. And they’re even helping reduce water requirements, and/or remediating the produced water and mines of years past that are now leaching toxins. And that’s translating into cost savings for mining companies, which are being held increasingly accountable for their environmental impacts and are looking for ways to minimize the expenses of both the production phase of their operations, and reclamation.

Could Resilience Become the New Green?

The latest EBN feature article is new available. Click on image to enlarge.

A new feature article in Environmental Building News examines how a focus on resilient design could advance green building more quickly than our current focus on sustainability.



Sometimes advancing sustainability feels like pushing a boulder uphill. Are we like a modern-day (benevolent) Sisyphus who keeps pushing the idea of sustainability uphill only to have it roll back down as other priorities grab society’s attention?

I thought about this question during a six-week bike trip through the Southwest at the beginning of my sabbatical from BuildingGreen. To be sure, there has been a lot of improvement in building practices over the past few decades. Standard levels of insulation have risen in homes, and windows have gotten better. We’re using daylight more effectively. Efficiencies of virtually all mechanical systems have improved. Photovoltaic modules have become more cost-effective.

There are innumerable improvements being made to buildings, but climate scientists tell us that we’re only chipping away at the edges. If we are to prevent a climate catastrophe in the century ahead, we need to make far more dramatic progress. Rather than incremental improvement, we need threshold improvement–an order-of-magnitude reduction in fossil fuel consumption. How will we get there?
I thought about that a lot in the hot, dry sunlight of Arizona and Texas as I snaked my way across 1,900 miles of gorgeous terrain.

Resilience as a motivation for change



I came to the realization that we need motivation beyond simply “doing the right thing” or staving off climate change–a distant and overwhelming-sounding task. What if people did all this stuff (building carbon-neutral homes and weaning themselves from automobile dependence, for example) not because it was good for the planet, but because of self-interest?

For you and me, that probably isn’t necessary. Anyone reading Environmental Building News or perusing BuildingGreen resources regularly is probably already convinced that we need to make these sorts of changes for reasons of altruism. But for lots of other people, that isn’t the case. And even people committed to the need for addressing climate change are sometimes overwhelmed by the shear magnitude of the challenge and what can seem like insignificant contributions that they are making.

The idea with resilient design is to turn sustainable design practices into necessity in an age of advancing climate change. We need to build ultra-low-energy homes and create bicycle-friendly communities to keep our families safe as a warming climate makes storms more frequent, causes more flooding, knocks out power more frequently, and produces extensive regional droughts.

These are some of the arguments I make in our latest EBN feature article, “Resilient Design: Smarter Building for a Turbulent Future” (requires log-in). The article addresses five general observations about resilience and why we need it, then presents 59 specific strategies in a detailed Checklist of Actions.

By implementing these actions, we can create homes and other buildings that will maintain livable conditions in the event of extended power outages, loss of heating fuel, or shortages of water. We can transition to communities that have strong, locally based economies and rely on locally produced food. We can reduce our dependence on cars so that if political turmoil in the Mideast doubles or triples the price of gasoline, we won’t be as affected.

These are practical, common-sense solutions that can drive the green building movement, I believe, more rapidly than is possible when we make change only because it’s the right thing to do. In fact, due to the life-safety benefits, some of these measures could actually be incorporated into building codes. We require seismic codes in areas prone to earthquakes. Why not implement building codes that will ensure that new houses incorporate enough insulation, passive solar gain, and natural cooling strategies that they will never put their occupants at serious risk should extended interruptions occur in our power or heating fuel supplies?

I look forward to your input. Is this a reasonable argument? We instituted seismic codes after the San Francisco Earthquake and fire codes following the Great Chicago Fire. Is it time for building codes to mandate superinsulation and passive solar design as safety measures, just as we did in response to those other catastrophes?

FSC and Beyond: LEED 2012 Buries the "Wood Wars" Hatchet

After months of controversy, the third public comment draft of LEED 2012 strengthens commitments to both FSC and local wood–while not budging on the importance of life-cycle assessment.

This is Part 2 in our “Wood Wars” series.

Part 1: Are FSC and LEED Killing American Jobs? A Look at the Evidence

Next: forests and global warming

In this ad from last year, several heavy-hitting environmental groups attempted to show the difference between life-cycle metrics and performance-based standards–and also objected to the since-revised credits for biobased materials. Click to embiggen.

For years, certified wood has ignited tempers and dominated discussions of building materials in the LEED rating systems.

The U.S. Green Building Council (USGBC) is clearly ready to expand the scope of that discussion. In the LEED 2012 drafts, this readiness has been reflected in a gut renovation of the Materials & Resources section, which offers a variety of credits having to do with product transparency by rewarding life-cycle assessment and disclosure of chemicals of concern. (See our coverage of the non-wood-related updates on our sister site LEEDuser–where LEEDuser members can participate in forums–and watch for more over at EBN.)

Opponents of these now-controversial credits have been very vocal. Among them is the Forest Stewardship Council (FSC), which has fought fiercely against a focus on transparency that might let unsustainable forestry practices get a foot in LEED’s door (see the ad posted here). Just before the release of the third draft of LEED 2012, a group including FSC, Perkins+Will, HOK, Cascadia Green Building Council, and the Healthy Building Network released a slightly softer statement of consensus (PDF) calling for “balanced recognition of leadership performance standards and LCA-based disclosure tools in LEED 2012.”

USGBC is also feeling heat from federal and state governments over its promotion of FSC-certified wood, which is falsely perceived as supporting importation.

The third LEED 2012 draft for public comment attempts to answer these concerns by deepening its commitment to both FSC and local wood. At the same time, it doesn’t give up on expanding the scope of LEED to embrace transparency, though the new draft does seem to bring more balance to the relative weighting of transparency.

The LEED 2012 Wood Credits

There are three main subsections in the third draft that could potentially apply to lumber products:

  • Building reuse and whole-building life-cycle assessment (1–3 points)

    This option encourages reuse or salvage of onsite or off-site materials. It could include existing wood framing, wood flooring, etc., as well as steel framing and many other materials. Issues of wood certification and transparency don’t apply when building products are simply reused, although the effect of wood certification on whole-building life cycle assessment remains to be seen.

  • Material life-cycle disclosure and assessment (2 points)

    This controversial subsection promotes transparency by offering three different options (see more about the conflict in our prior coverage, along with USGBC’s rationale for incentivizing transparency). The first two would give one point each for using products that have a third-party-reviewed life-cycle assessment (LCA) or environmental product declaration (EPD); one point is for transparency for 20% of non-structural materials, and one point is for transparency for 20% of structural and enclosure materials.

    The section has been controversial because it rewards transparency without regard to a product’s environmental performance: in theory, cedar clapboards harvested using slash-and-burn forestry practices could be used in calculations for achieving one of these credits–just by virtue of having an LCA or EPD associated with it. There are also issues with the ability of LCA (which is the methodology underlying EPDs) to capture ecosystem damage and many other impacts. (See “The End of Greenwashing? Five Myths about Product Transparency” for a quick take on the limitations of LCA.)

    The other option is called “multi-attribute assessment,” which is an odd name since it appears to be based on single attributes: materials reuse, recycled content, and local sourcing. This third option sets a high bar for achievement: 50% of nonstructural products.

  • Responsible extraction of raw materials (1–2 points)

    All new wood products used to achieve this credit must be FSC-certified “or better.” The only exception to this is wood harvested and milled within 50 miles of the building site–a significant change from prior versions of LEED, which gave credit for “locally” sourced wood and other materials within 500 miles of the site.

    The whole subsection on extraction of raw materials also has local-sourcing tiers for calculating credit, which is based on percentage by cost. Domestic products have their cost value multiplied by 1.5; in-state or in-province products have their cost value doubled; and products from within 50 miles/80 km have their cost value tripled. It’s a major incentive for using locally and regionally sourced materials, which fosters local economies and could potentially quell arguments against using LEED for government projects–despite LEED 2012′s renewed commitment to FSC for wood sourcing.

Two other subsections could apply to composite wood products:

  • Disclosure of chemicals of concern (1 point)

    While wood products are not the first thing that come to mind, sheathing products or composite countertops, for example, could count toward a credit collected for disclosure of chemicals. Again, the credit is based on disclosure itself–not on whether there are high levels of formaldehyde or other chemicals we should be concerned about.

  • Avoidance of chemicals of concern (2 points)

    Unlike the disclosure credit, which was previously combined with the avoidance credit, this subsection addresses the actual performance of products and rewards them for reductions in chemicals of concern. So a sheathing product or composite countertop that avoids formaldehyde or other chemicals on the list could count toward these credits in addition to the disclosure credit.

Is This a “Back Door” for SFI?

By my count, that makes three points based entirely on transparency that could potentially be used for wood products, as opposed to seven based on specific green attributes. It remains to be seen how opponents of the weighting in the previous draft will react, but there are those who thought that a focus on transparency would let FSC’s competitor–the Sustainable Forestry Council (SFI)–in through a “back door” in LEED. Should we be worried about this?

USGBC doesn’t think so. “That accusation can’t be made without already fundamentally misunderstanding the rating system,” said Lane Burt, director of technical policy at USGBC. “Right now you can get credit for any wood within 500 miles [for the Regional Materials credit], and you only have to use 50% of wood that’s FSC-certified [for the Certified Wood credit].” That means lots of SFI-certified wood and non-certified can be used for LEED regional points, while the project could still earn the Certified Wood point with FSC material.

Revising local sourcing to 50 miles is a huge change that could close out a lot of previously accepted SFI-certified and non-certified products for achieving this particular credit. If any other wood products are going to be included for LEED credits, if they are not sourced from a 50-mile radius, they’ll now have to do it almost exclusively through transparency–by having LCAs or EPDs or by disclosing chemicals of concern.

But that’s not really the point anyway, as far as the crafters of the system are concerned. Burt continued, “We’re now moving away even from wood and local credits to something more robust and realistic. People can continue to make those accusations, but they are going to be even more fundamentally flawed in their premise.”

Eyes on the Prize

Brendan Owens, P.E., vice president of LEED development for USGBC, acknowledges the historic leadership role of FSC and encourages FSC to support efforts to increase transparency. Because standard LCA methodology is currently limited, part of the point, he says, is to incentivize further development of these tools.

“Wouldn’t it be great if we had quantifiable metrics that allow us to distinguish between FSC and SFI?” asked Owens. Instead, he said, “We rely on proxies rather than data.” In the long term, Owens anticipates “the 2.0 or the 3.0″ version of forestry standards–driven by the development of better measurement tools. “We want to push that,” he said. But right now, “we’re not getting the information that allows us to quantifiably say that the things we are assigning as proxies are necessarily outcomes.”

Owens challenged FSC supporters to look at the forest instead of the trees: “One of the things that’s important about this is the fact that we are juggling at least seven different environmental and social issues simultaneously across a complex infrastructure for design, construction, operation, and maintenance of buildings,” said Owens. “Buildings are not a wood issue. It’s the other way around.”

“The Soul of the Green Building Movement”

Jason Grant, a consultant to the sustainable forest products industry and a long-time backer of FSC, sees things a little differently. “Forests matter,” he said in an interview conducted before draft three of LEED 2012 was released. “They are one of the key systems for our survival. It is fundamental.”

Grant believes that sustainable forestry isn’t just about two or three credits. “It’s about the soul of the green building movement. It’s about the soul of LEED,” he said. “Are we going to capitulate to greenwashing and an intense pressure campaign? Or are we going to stand strong for what LEED is supposed to be about? That really matters.”

I find both of these passionate arguments moving and convincing. And I don’t actually think they’re mutually exclusive. LEED is large; it contains multitudes.

I’ll be curious to hear what Grant and other FSC supporters will say about the third draft once they’ve had a chance to mull it over. Does it thread the needle? Or is it a poke in the eye? What do you think? Let us know in the comments.
