Synthetic 'tree' promises to catch carbon

The thought of an artificial tree usually excites memories of building and ornamenting a Christmas centerpiece. But here's an innovation that will put those plastic branches to shame: scientists at Columbia University are developing a structure that can capture carbon 1,000 times faster than a real tree.

Klaus Lackner, a professor of geophysics at the university, has been working on the project since 1998, according to a CNN report, and is optimistic about a near-future application.

Modern improvements in coal-fired power plants have reduced carbon emissions, but Lackner is seeking a different function. The "tree" would be used to trap carbon that has already been emitted into the air by car gasoline or airplane fuel, CNN reports.

Unlike the real thing, the synthetic "tree" doesn't need direct sunlight, water, a trunk, or branches to function, as it looks more like a cylinder than a soaring Redwood. The concept, which Lackner says is flexible in size and can be placed nearly anywhere, works by collecting carbon dioxide on a sorbent, cleaning and pressurizing the gas, and releasing it. Similar to the way a sponge collects water, the sorbent would collect carbon dioxide.… Read more

What's the carbon footprint of your handwash?

Start-up Planet Metrics is developing software that could give consumers a better read on the embedded energy of everyday products.

The San Francisco-based company on Tuesday released the beta test version of its hosted application, which it calls Rapid Carbon Modeling. It also said Method, which makes eco-friendly home-cleaning products, is a customer.

There are a number of companies writing software for calculating how much energy is linked to a business' operations and managing carbon emissions. Planet Metrics' software is geared at manufacturers and makers of consumer packaged goods.

Using Planet Metrics' software, a person could, for example, see how … Read more

Carbon software company claims broad patent

Verisae, a small Minnesota-based company, has received a patent for a system to track and report greenhouse gas emissions with software, a business attracting a growing field of companies.

The company on Wednesday said that the U.S. Patent and Trademark Office issued a patent to Verisae for a method for calculating a corporation's emissions. The patent, filed in May of 2007, describes a business process for gathering corporate emissions data, generating reports, and managing carbon credits.

Verisae is already offering hosted carbon accounting software focused primarily on retail companies, basing its tracking and reporting on the protocols established … Read more

NEC monitor tracks your carbon emissions

A couple months back, I talked about Dell's new Eco-friendly monitors, the G2210 and G2410, which feature on-screen displays (OSDs) that allow you to see, in real time, how much energy your monitor is using depending on its current brightness level. In the original blog, I commented that I hoped more developers would follow Dell's lead, and it looks like NEC will be the first to try--perhaps even topping Dell.

On Tuesday, NEC announced the MultiSync E222W, a 22-inch LCD monitor with a host of ergonomic and Eco-conscious options.

The monitor includes 110 millimeter height adjustment, pivoting, swivel, and tilt. It also includes an Eco Mode that purportedly reduces power consumption and heat generation.

Also, according to NEC, its Intelligent Power Management and off timer will help conserve energy and reduce carbon dioxide emissions by switching to a low-power state or automatically powering down when the monitor is on but is not in use. This feature apparently circumvents OS-based power options.

Taking a page out of Dell's aforementioned unique OSD options, the MultiSync E222W will allow users to track their carbon footprint savings, with what NEC calls the display's carbon footprint meter.

According to NEC, the tool takes the concept used in the Dells one step further by actually calculating the reduction of green gas emissions, unlike Dell's tool, which only shows energy readings relative to the monitor's brightness.

Hara: Software for a carbon-constrained economy

Start-up Hara Software is betting that businesses need to get smarter about managing natural resources and carbon emissions even before regulations force them into it.

The Silicon Valley start-up on Monday is scheduled to come out of stealth mode after 18 months to announce the details of its software service which it designed for what its founder calls a "post-carbon economy era."

The 25-person company received $6 million in venture capital from Kleiner Perkins Caufield & Byers, where partner Al Gore played a role in getting Hara funded. It's the second software-focused investment after PC power management … Read more

House committee OKs climate bill

The House Energy and Commerce Committee passed an energy and climate bill on Thursday that puts a cap on greenhouse gases in a way designed to give heavy polluters years to transition to low-carbon technologies.

The American Clean Energy and Security Act of 2009, sponsored by Congressmen Henry Waxman and Edward Markey, passed through the committee after four days of marathon "markup" sessions where dozens of amendments were considered.

The bill calls for a cap-and-trade system designed to reduce greenhouse gases and a mandate that would require utilities to get a portion of their electricity from renewable energy … Read more

SAP buys into carbon management

Having mastered ways to automate manufacturing and dozens of other business processes, SAP is now acquiring expertise in managing carbon emissions.

The enterprise software giant said on Monday it has acquired 2-year-old, privately held Clear Standards, a Sterling, Va.-based software company with tools for tracking and reporting a corporation's environmental impact. No financial terms were disclosed.

Clear Standards' Web-based hosted applications are designed to help a company develop a strategy for managing carbon emissions and reducing its environmental impact. The software can create an inventory of a company's emissions and then give an environmental regulations manager, for … Read more

Do Google's carbon offsets add up to much?

Google, a company that runs power-hungry data centers, employs thousands of people, and operates a corporate jet, said on Wednesday that it was carbon neutral for the past two years. How so? Offsets.

The idea of a carbon offset is to compensate for the greenhouse gas emissions of a company or person by investing in a project that reduces emissions from the atmosphere.

Google sees offsets as an imperfect method for lowering their total carbon footprint, among other efforts. To detractors, offsets are essentially greenwashing when companies do little more than buy offsets to meet their environmental sustainability goals.

There … Read more

Grading Google's carbon neutral claims

Google reached its goal of becoming carbon neutral for 2007 and is almost entirely neutral for 2008, Google's Green Energy Czar Bill Weihl announced on the official Google blog Wednesday evening.

In June 2007, Google had announced it was going to try to become carbon neutral by the end of that year by working to maximize its efficiency, investing in renewable energy resources, and as a last resort and interim solution buying carbon offsets.

In Wednesday evening's post announcing the company had finally achieved that goal, Weihl reiterated the company's 2007 promise of using carbon offsets was … Read more

Scope of clean energy, climate bills takes shape

Policies now being considered to boost renewable electricity generation and efficiency at utilities will make it cheaper to comply with caps on greenhouse gas emissions, said members of the Energy Future Coalition, a group of business, environmental, and labor advocates.

Both the the House and Senate are expected to move ahead with energy and climate change bills in the coming weeks.

The Waxman Markey bill in the House combines both energy and climate regulations in a single bill, while the Senate is working on separate efforts. Committee markup meetings in the House and Senate are expected, starting as early as … Read more
