Emissions rising faster this decade than last
October 02, 2008The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.
"This is a concerning trend in light of global efforts to curb emissions," says Global Carbon Project (GCP) Executive-Director, Dr Pep Canadell, a carbon specialist based at CSIRO in Canberra.
Releasing the 2007 data, Dr Canadell said emissions from the combustion of fossil fuel and land use change almost reached the mark of 10 billion tonnes of carbon in 2007.
Using research findings published last year in peer-reviewed journals such as Proceedings of the National Academy of Sciences, Nature and Science, Dr Canadell said atmospheric carbon dioxide growth has been outstripping the growth of natural carbon dioxide sinks such as forests and oceans.
The new results were released simultaneously in Washington by Dr Canadell and in Paris by Dr Michael Raupach, GCP co-Chair and a CSIRO scientist.
Dr Raupach said Australia's position remains unique as a developed country with rapidly growing emissions.
"Since 2000, Australian fossil-fuel emissions have grown by two per cent per year. For Australia to achieve a 2020 fossil-fuel emissions target 10 per cent lower than 2000 levels, the target referred to by Professor Garnaut this month, we would require a reduction in emissions from where they are now by 1.5 per cent per year. Every year of continuing growth makes the future reduction requirement even steeper."

Carbon Emissions Current Events and Carbon Emissions News RSSORNL, Los Alamos pioneer new approach to assist scientists, farmers
Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories.
Berkeley Lab Lends Expertise to India to Promote Energy Efficiency
ndia may rank only a distant fourth in terms of carbon dioxide emissions, behind China, the United States and Russia, but its rapid economic growth rate coupled with aging and inefficient energy infrastructure suggest dire environmental consequences if "business as usual" continues.
Health care accounts for 8 percent of US carbon footprint
The American health care sector accounts for nearly a tenth of the country's carbon dioxide emissions, according to a first-of-its-kind calculation of health care's carbon footprint.
Researchers Hail Innovative Plan to Save Rainforest, Reduce Greenhouse Gas Emissions
An innovative proposal by the Ecuadorian government to protect an untouched, oil rich region of Amazon rainforest is a precedent-setting and potentially economically viable approach, says a team of environmental researchers from the University of Maryland, the World Resources Institute and Save America's Forests.
Simple measures can yield big greenhouse gas cuts, scientists say
New technologies and policies that save energy, remove atmospheric carbon and limit greenhouse gas emissions are needed to fight global climate change - but face daunting technological, economic and political hurdles, a Michigan State University scientist said.
Growth versus global warming
Houses on stilts, small scale energy generation and recycling our dishwater are just some of the measures that are being proposed to prepare our cities for the effects of global warming.
Concentrating emissions
Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants.
Smaller isn't always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality.
Scientists say climate change mitigation strategies ignore carbon cycling processes of inland waters
In the paper, The Boundless Carbon Cycle, published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud™ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player - inland waters.
Agricultural methods of early civilizations may have altered global climate, study suggests
Massive burning of forests for agriculture thousands of years ago may have increased atmospheric carbon dioxide enough to alter global climate and usher in a warming trend that continues today, according to a new study that appears online Aug. 17 in the journal Quaternary Science Reviews.

Conquering Carbon: Carbon Emissions, Carbon Markets and the Consumer by Felicia Jackson (Author) This is a book to help consumers understand the consequences of carbon emissions and why we cannot afford to ignore them. 2009 will be a pivotal year in terms of carbon markets. A successor to the Kyoto Protocol is to be agreed by the end of the year and it essential that individuals start to understand and take responsibility for their carbon footprints. Carbon markets are the key to the largest economic change since the Second World War. We need to alter our relationship with carbon by learning how best to manage and prevent the loss of our resources in order to increase our sustainability. "Conquering Carbon" provides a clear overview of the role of carbon and the direct effects of our relationship with it. By providing a historical overview of global warming and key issues, examining... |

2008 Global Conference: Market Solutions to Climate Change: The European Experience Europe has taken a proactive approach to addressing climate change, with the EU committing its 27 member states to reducing their carbon footprints by 20 percent beyond the Kyoto accords by 2020. The enormous cost of emissions reduction will fundamentally alter how business is done, driving massive investments into efficiency and renewables. The EU's early action has also translated into market leadership for the continent's major players in clean tech. This panel from the 2008 Milken Institute Global Conference reveals what the rest of the world can learn from the European experience.

AC-Energy Saver 220V UL Approved with Surge Protection by ACEnergySaver, Inc. Incorporating power-factor (PF) correction can mean life-cycle cost savings of appliances for home owners. PF measures how efficiently current is being converted into useful real work. The closer the PF is to 1, the more efficient the electrical usage. The average home in the U.S. has a PF of 75%, which means 25% of electricity is wasted. Our device can save up to 80% of this average waste. |
