In the summer of 1999, I received a call from Laura Bush. She and then-governor George Bush wanted a design for a house that would blend into the landscape of an extraordinary piece of land they had just purchased in Crawford, Texas. We talked at length about environmental systems, and Laura was clear at the outset that they wanted to do everything possible to protect the land. It is exceptionally beautiful, with deep bluffs, streams and stands of native live oak.

The house is designed to use a quarter to a third of the energy of a normal house its size. With some modification, it could run entirely off the grid. There are dozens of features that contribute,

ROCKY ANDERSON
Mayor of Salt Lake City

In Salt Lake City, we've been able to reduce greenhouse-gas emissions in our municipal operations by 31 percent in four years. We've eliminated 143 cars from the city's light vehicle fleet, and replaced 41 SUVs with smaller, more efficient cars. By retrofitting all city and county buildings with compact fluorescent bulbs, we save the city $33,000 a year. We then invest one third of that in wind power, making Salt Lake City the state's largest purchaser of wind power. We also changed all the city's traffic lights from incandescent bulbs to LED lights, which saves about $50,000 a year in electricity while also reducing annual carbon emissions by 500 tons. Those are just a few small, easy changes that net

MARY T'KACH
Executive director, Environmental Sustainability for Aveda

Since our inception in 1978, our focus has been on producing plant-based personal-care products. Currently, 90 percent of the essential oils that go into our products are certified organic, and, as we continue to learn about the functionality of plants, we are able to use even more. That's been a lot of work for our suppliers. In terms of the industry, we're certainly a leader, as a lot of companies have come into organics. In the scope of personal- care products, we're small but we've been a catalyst for so much change. The packaging of products, to how stores get designed, we're always getting chased. So it's good to see the big players step in and say there's some

A chance to fix a neighborhood
There is a huge hole in our economic fabric where clean tech should be. And residents of this community can be trained to fill these "green collar" jobs. Instead of all these economic-growth agencies pushing for stadiums or big-box stores where the average wage is $7 an hour, the city could invest in cleaner transportation systems such as barges and rail lines to connect us to the rest of the city. We could take all the waste grease from the food industry that now gets trucked here for disposal and process it instead into biodiesel fuel. Workers will install "green roofs" on commercial buildings, which will provide cooling and generate

The ocean's food chain is at risk
We were one of the first to call attention to the acidification of the oceans. The oceans take up a huge amount of carbon dioxide from the atmosphere every year. A portion of that carbon gets turned into carbonic acid, so that the more carbon dioxide there is in the atmosphere, the more acidic the oceans become. The oceans are now 30 percent more acidic than they were before the Industrial Revolution. It's the most chilling change I've seen in my professional career. If it continues, tiny organisms at the base of the food chain will have their shells dissolve while the animals are still alive. It will

New stores will use less energy
Hurricane Katrina was a big turning point for us. It showed us that we've got a role we can play that might be greater than we realized. Two years later, we have prototype stores-the first is in Kansas City, Mo. It uses LED lighting in the freezers, and a heating and cooling system without a fan. That store uses 20 percent less energy than a store we'd have opened in 2005. One product we're promoting heavily are compact fluorescent light bulbs, or CFLs. They account for only 5 percent of light-bulb sales, but at Wal-Mart we've been redoing our aisles to make CFLs more visible. Today 20 or 30 percent of the light-bulb aisles will be CFLs, mostly at eye

K. R. SRIDHAR
Founder and CEO, Bloom Energy

Look at the crisis as an opportunity
I think the debate about the climate crisis in this country has been framed the wrong way. We've been talking about it from the perspective of the cost to society, rather than the point of view of the opportunity for profit. People are missing that this is a $4 trillion market for energy, and that's before we factor in the supply-demand imbalances that will occur as China and India ramp up their energy use. There is both a climate crisis and an impending energy crisis, and as Stanford economist Paul Romer has said, a crisis is a terrible thing to waste. Energy is just the capacity to do work, and work is what creates economic output. I'm not against

Director of Corporate Responsibility, Intel

Being green is just good business
As the largest chip manufacturer worldwide, Intel has been leading the area of environmental excellence for decades. For us, being green is just part of the way we do business. One thing that plays to our advantage is that our manufacturing process essentially gets refreshed every few years. We can anticipate that, so instead of having to retrofit facilities, we've applied a philosophy of design for environmental health and safety that projects eight to 10 years down the road. With each step we take in successive generations of the chip, we employ different manufacturing recipes every two years. So when we went from the eight-inch wafer to the 12-inch

President, Wildlife Trust

Cutting down trees can lead to malaria
One of the most important and overlooked ecosystems in the world is in areas of rapid land conversion, where agriculture is encroaching on wilderness and where wildlife, livestock and humans are in close proximity. When you talk about emerging diseases, that's where they're emerging from. Nipah virus, which was first identified in Malaysia in 1999, is an example. Pig farms were carved out of forested areas, and fruit orchards were planted next to the pig enclosures, which brought pigs into contact with fruit bats, the natural reservoir for Nipah virus. The virus spread to pigs and then to the farmers, and the ones who caught it had a 40 percent mortality

Europe is propping up an unsustainable industry in an extreme example of short-termism that our children will pay for
by George Monbiot

All over the world, protesters are engaged in a heroic battle with reality. They block roads, picket fuel depots, throw missiles and turn over cars in an effort to hold it at bay. The oil is running out and governments, they insist, must do something about it. When they've sorted it out, what about the fact that the days are getting shorter? What do we pay our taxes for?

The latest people to join these surreal protests are the world's fishermen. They are on strike in Italy, Spain, Portugal, France and Japan, and demonstrating in scores of maritime
