The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?

The debate surrounding global climate change has been a very hot button issue for the past few years. In most cases the average person doesn’t know enough about the science behind this issue to make an informed decision. The fact is that climate change will become a major issue within the next two decades and will have a host of environmental as well as economic impacts in the United States. Climate change will play a major role in the way our economy functions as well as the way our legislators make decisions.
In recent years there has been a ‘boom’ in the availability of online carbon emission calculation tools. It seems as though every company with the slightest interest in the area is offering assistance on both commercial and personal levels. This do-it-yourself approach offers pros and cons, opportunities and problems. Are these tools reliable? Do they do what they say they do or are they simply a way to appear green whilst actually doing very little? This article seeks to explain the issues surrounding this type of emissions calculation and answer these important questions.
Stephen Hinton, provides a compilation of professionals that will see growth as the US economy goes green. He predicts that those in STEM professions (Science, Technology, Engineering and Mathematics) will experience the most job security.
In a major new announcement, the U.S. Environmental Protection Agency (EPA) has concluded that greenhouse gases (GHGs) threaten the public health and welfare also explicitly stating that GHG emissions from on-road vehicles contribute to that threat. This conclusion by the EPA has been reached after a thorough examination of the scientific evidence and careful consideration of public comments.
Carbon Offsets are responsible for a huge debate within the environmental and sustainability sectors. Do they help? Are standards adequate to achieve the goal of the scheme? Sould they be banned? This article presents an arguement in support of carbon offsetting, covering the basic theory and issues behind the idea.
A new study by the Marine Biological Lab (MBL) of Woods Hole Oceanographic Institution (WHOI) has reported that biofuels that displace food crops may have a much bigger carbon footprint than previously thought. MBL senior scientist Jerry Melillo and his colleagues at the MBL have reported that carbon emissions from land-use change caused by the displacement of food crops and pastures by a global biofuels program may be twice as much as the emissions from lands directly devoted to biofuels production.
With global eco awareness expanding on climate issues, it is not a surprise to many that the fastest growth in CO2 levels has occurred in the last 10 years. Studies indicate that electricity generation and consumption is the largest contributor and is increasing faster than any other energy sector. However, efforts to manage electricity show the slowest decline in emissions progress.
This country’s 130 million homes together generate more than 20% of the nation’s carbon dioxide greenhouse gas emissions. This is one of the most significant contributing sources in the country to global warming. Existing techniques and technologies in energy efficiency retrofitting can reduce home energy use by up to 40 percent per home on average which would also lower our national greenhouse gas emissions by 160 million metric tons annually by the year 2020. In addition doing so would reduce home energy bills by $21 billion a year and over time these savings would more than pay for the high up-front costs for energy efficiency retrofitting.
