Legislation that would require limiting emissions in 2012 gets support from both parties. The landmark bill would establish an independent group to oversee a cap and trade system and require a 65 percent reduction in greenhouse gas emissions by 2050.

The Department of Energy (DOE) will spend nearly $200 million over the next decade to test the efficiency of sequestering carbon generated from burning coal. According to a new report from the Carnegie Mellon Electricity Center, large scale carbon sequestration is technically possible, but could cost billions of dollars per year.

The DOE announced this month that it would spend $197 over the next ten years on three pilot programs to test the feasibility of storing underground carbon generated from coal plants. The DOE will pay for 62 percent of the $318 million projects, and the private sector including utilities will pay the remainder.

According to DOE the three deep saline reservoirs near the pilot projects span parts of 27 states and 3 Canadian provinces and can store up to 100 years of the total carbon output of the U.S.. The three projects will store 1 million tons of carbon underground, doubling the amount currently being sequestered.

Collectively the projects will store approximately .05 (five one hundredths) of one percent of the carbon generated by coal power plants annually, according to data from the Energy Information Administration.

The Carnegie Mellon Electricity Center on October 15 published a new report entitled "Incentives for Near-Term Carbon Dioxide Geological Sequestration" that outlines the potential and the cost for sequestering carbon while suggesting the government incentives needed to make it cost-effective for the power industry.

According to the report, "Carbon capture and deep geologic sequestration holds the promise to make deep carbon emission reductions possible with the continued and increased use of coal and petroleum coke (petcoke)."

CO2 can be safely sequestered "essentially indefinitely," according to the report, but "financial incentives are necessary to begin commercial scale [sequestration]." The study suggests sequestering carbon at gasification sites because "transport and sequestration costs are estimated at $5-$15 per ton of CO2."

Based on DOE estimates for the three pilot projects, carbon sequestration will cost approximately $30 per metric ton.

Because of the high cost of sequestration, the report suggests a broad array of federal tax incentives to make carbon sequestration viable for power companies, including:

Continue the 15% enhanced oil recovery federal tax credit

Enact a federal CO2 sequestration tax credit.

Enact a federal investment tax credit for CO2 pipelines.

Add low-carbon emission coal facilities to the facilities eligible for the production tax credit.

Enable tax-exempt financing for CO2 sequestration infrastructure investments'

Each kilowatt hour of electricity produced by a coal plant generates slightly less than one (0.94) metric ton of coal, so the cost of transporting and sequestering all of the carbon generated by coal power plants would be between $10 and $30 billion annually.

Independent testing facilitated by Greenpeace International revealed that the iPhone contains two types of hazardous substances -- brominated compounds and toxic phthalates. While not outlawed in mobile phones, the phthalates have been banned in toys and childcare products in Europe because of their "ability to interfere with sexual development in mammals."

According to the report from Greenpeace, other mobile phone makers have already eliminated the use of the chemicals. The brominated compounds were found in the phone's antenna, while the toxic phthalates were found in the PVC coating of the headphone cables.

Greenpeace also criticized Apple for not coordinating the recycling of the phones so that that they do not end up in landfills.
