The UK's share of international shipping would be potentially responsible for up to 11.25% of all emissions that are allowed by 2050 as set by the Climate Change Act according to the Committee on Climate Change (CCC). This equates to 18 Mt CO2 out of a total of 160 Mt CO2.
Trees could be redundant as far as carbon debts are concerned. Together with his artificial tree, Professor Klaus Lackner has been working on carbon absorption for many years. After trying artificial carbonates and storing liquid CO2, he has brought his latest ideas to the Institution of Mechanical Engineers' Air Capture Week in London.
Obtaining biofuel from forests has been shown to increase carbon emissions. Biofuel production is not without controversy; the food or fuel debate cannot be avoided in developing countries and the impact on water resources is unavoidable. The drive to find alternatives to fossil fuels has caused as many arguments as it has found solutions.
A previous explanation for the warming that ended the last ice age has been called into doubt. The last ice age was lengthy, taking place over a period of 25,000 years. It covered over a third of the earth and ended over 10,000 years ago. How the glacial period ended has been a matter of dispute, but one accepted theory was that a significant release of carbon dioxide from the ocean was the cause.
The New York Stock Exchange might not be an obvious green pioneer, but the historic building's new windows are saving CO2 emissions. The windows, which have been approved by the Landmark Preservation Commission which safeguards national landmarks, will improve the building's thermal performance by 60% and reduce the solar heat gain by 40%.

A Stanford University scientist is claiming that action on soot could have immediate and dramatic effects on slowing global warming, and reducing deaths from smoky air. The model being presented at the 242nd American Chemical Society meet suggests that soot is the second-biggest contributor to global warming - but that controlling it could be cheaper, and produce results faster, than the ongoing battle to reduce CO2.
One of the most powerful greenhouse gases is being released into the atmosphere in far higher quantities than European governments are reporting says a new report. HFC-23 is a so-called super greenhouse gas which has a global warming potential some 14,800 times higher than CO2.
As high-latitude permafrost thaws following climate change, a new study reveals that released CO2 can accellerate the process. Billions of tonnes of carbon are trapped in this permafrost and this will be released as the permafrost begins to thaw and early predictions were that the growth of the new vegetation would pull more carbon from the atmosphere than the permafrost would release.
Historic Florida community shows beauty and sustainability can be combined. Anna Maria Island in Florida is becoming a zero-carbon community. It's not got there yet, but the drive and vision of its co-owners, energetic husband-and-wife team Lizzie Vann Thrasher and Mike Thrasher, is powering it onwards, or rather downwards - in terms of energy use and carbon emissions.
The World Wide Fund for Nature (WWF) is encouraging the British public to celebrate the cultural and natural heritage of forests and woods, Jessica Allan highlights the importance of their campaign. In global climate change; trees act as carbon sinks, so their loss increases the amount of carbon dioxide present in the atmosphere.
Researchers discover that forests with younger, more diverse, species of trees are more effective at soaking up carbon than their older trees. Forests act as CO2 sponges, soaking up to 2.4 billion tonnes of greenhouse gases annually - almost a third of all CO2 released through the burning of fossil fuels each year.
A paper out in Nature today suggests that the touch-paper for runaway global warming could be lit by increased fires in the previously damp tundra soils of the Arctic. Such fires have been absent for 11,000 years - their reappearance could help cause permafrost to melt more readily, in a chain-reaction of CO2 emissions that would boost global warming.
News of AEP's cancellation of its carbon capture trial after mixed success have added to worries that CCS (Carbon capture and Storage) is struggling to match hopes for helping with the global carbon conundrum. And a new report into reusing CO2 - released yesterday by the UK's Center for Low Carbon Futures - is a reminder that potential their may also be too little too late.
The mass extinction 200 million years ago, that paved the way for the rise of the dinosaurs, could have been caused by a massive belch of methane, say scientists in a paper just published online on ScienceExpress. Plant remains show that the atmosphere was rapidly filled with carbon, which could have come from CO2-driven warming, releasing the methane stored in the cold sub-sea sediments.
Study of American foodstuffs finds lamb has the biggest carbon footprint. The study found the foods with the biggest carbon footprint include lamb, beef, cheese, pork and farmed salmon. Lamb has the greatest impact on the environment with a generation of 39.3 kg of carbon dioxide per kilo eaten.
A study carried out by the French Agency for the Environment warns that emailing is just as bad for the environment as flying. At an average size of 1 MB and 220 working days per year, ADEME has calculated sending work related emails generates 13.6 tonnes of CO2, about 13 round-trip flights from Paris to New York.
Biofilters can convert around a fifth of the wasted methane from old landfill sites into less harmful gases says new research. Methane has a much greater impact on global warming per amount of gas than carbon dioxide and landfills account for 12% of global anthropogenic methane emissions.
Warming oceans may be finding it harder to take their share of our CO2 emissions, says an upcoming study out in Nature Geoscience today. The three-decades of North Atlantic data analyzed suggest, for the first time, that climate change is causing the oceans to pass the CO2 buck straight back to us.
Scientists have turned to fossils from a previous time of high CO2 concentrations and found that previous temperature predictions have probably been too high. The team studied growth rings in the shells of molluscs and tested other material found in the fossils.
British Conservative MEPs were instrumental in throwing out an EU report that goes against the wishes of their party's national government says WWF-UK. The European Parliament voted not to follow the recommendations of an EU report that called for a 30% reduction from 1990 levels in greenhouse gas emissions by 2020.
A UK university today announced a £400,000 investment to develop automotive technologies which can save fuel and reduce carbon emissions. The move comes from the University of East Anglia, which says money from its Low Carbon Innovation Fund (LCIF) project will support development work already under way from Essex company Controlled Power Technologies (CPT).
An unprecedented number of marine species are at risk of extinction. Increasing levels of CO2 contributes to rising temperatures. In turn, increased temperatures lead to more CO2 being absorbed into the ocean. Increased CO2 in the ocean leads to increasing ocean acidification and hypoxia, which are devastating for marine life.
Aircraft engine manufacturer CFM International has announced the 1,001th innovation in its new LEAP engine, which is being hailed as a major breakthrough in environmental benefits. Also unveiling new innovations in aero engine design are Airbus and Rolls-Royce, who announced development of the A350-1000 aircraft with more powerful Trent XWB engines, the engine should reduce fuel use by 25 per cent and cuts in CO2 emissions.
Virgin America says its new engines will help keep the airline ahead of the game when it comes to greener travel.

NASA researechers have mapped the earth's forests as a baseline for carbon research and monitoring efforts, and as a tool for managing global carbon dioxide. The map shows that the tropical forests that store the most carbon are in Latin America.
Energy production continues to pump more CO2 into the atmosphere and the targets agreed by world leaders to limit warming to 2 degrees are now seriously threatened warns the International Energy Agency.
Scientists look to volcanic fissures to examine the effects of rising acidification in the world's oceans. As the seas become more acidic through global warming and increased carbon dioxide levels, there's a real possibility that coral reefs and the sea life that relies coral reef habitat could become extinct by the end of the century.
As temperatures rise forest soils will store less carbon says a new study but, according to Jerry Melillo, trees may see carbon-storing growth spurts too. However, the increased temperature also speeded up the nitrogen cycle, enabling trees to store more carbon, partially offsetting the CO2 released from decaying matter in the soil.
The announcement of 3 new advanced sensors for tracking oceanic acidity levels, made yesterday by the University of Alaska Fairbanks, will help scientists monitoring this worrying knock-on from rising CO2 levels. If CO2 levels keep pushing the ocean's acidity up, many organisms relying on limy shells will be threatened.
Carbon dioxide may be harmful to the environment, but it seems Europeans also believe it to be harmful to their health! Three quarters of those surveyed even considered CO2 to be ''unhealthy'', while 9% said they thought it was flammable and 18% believed it be a water pollutant, none of which is accurate.
Latest figures show Australia's carbon emissions are on the rise again. The latest data to be released by Australia's Department of Climate Change and Energy Efficiency shows that the emissions of carbon for the year of 2010 are 0.5 percent higher than the emissions from 2009.
Recent geoengineering conferences have raised the profile of how we might tackle global warming with a Plan B - finding ways to cool the planet down, whilst trying to agree on how to cut those pesky CO2 emissions. But could the Plan B of geoengineering be a dangerous distraction that ultimately locks us into a series of even greater risks?
Mars may well have had a much denser CO2-rich atmosphere hundreds of thousands of years ago - one with wilder dust storms and that was more likely to support running water. That's the claim coming from a new analysis of satellite radar data over the Martian southern ice cap - published in Science today - which hints at a thick wedge of frozen CO2 there that contains 30 times the 'dry ice' of previous estimates.
The EU put forward its long-planned carbon tax this week, a move that will change energy taxes so that they are based on carbon emissions. Loud complaints are already being heard from car-makers and driver-lobby groups. But the new rules won't initially raise fuel prices at all. And that is the real worry, as fuel use ultimately needs to reflect the real cost to the planet - which means, in the end, prices for the worst polluting fuels will have to rise.
A new World Bank report has found that drainage and degradation of coastal wetlands leads to decreased carbon sequestration and increased amounts of carbon dioxide in the atmosphere. If coastal wetlands are drained, for example to convert the land for agricultural use, they emit large amounts of CO2 into the atmosphere
The study of fossilised mollusks could give scientists an invaluable insight into the way the world will respond to climate change. Researchers at Californian university UCLA say that examining the fossils from 3.5 million years ago has allowed them to build a picture of how the world is reacting to current levels of atmospheric carbon dioxide, a key contributor to global climate change.
Greenhouse gas emissions rise in the UK. While the figures from the transport sector were stable, the government was quick to highlight that the bulk of the increase came from the residential sector, despite the fact that just 17% of all CO2 emissions comes from the nation's homes.
A 6% fall in CO2 equivalent emissions is the eye-grabbing figure from the EIA report for 2009 - a record-breaking drop. But that number is muddied by the contrasting effects of the recession, which pulled production, and so emissions, down sharply. But the reported continued decrease in carbon intensity offers a glimmer of hope for 2010.
Last summer's drought in the Amazon left vast swathes of forest visibly stressed, according to a study of images from 2 NASA satellites. This worryingly matches the predictions of drier, harsher times for one of the world's most biodiverse areas - and sets the scene for possible massive outpouring of CO2.
Carbon labelling will help consumers more accurately reflect their green intention says new research and producers will cut energy use and boost their environmental credentials too. Thomas Dietz, a sociology professor from Michigan State University, publishes his research in the new edition of Nature Climate Change and says carbon labelling will help reduce carbon emissions.
Cirrus clouds generated from the contrails of jets may be the cause of more atmospheric warming today than all the CO2 emitted by the aviation industry since the beginning of flight. Aviation is responsible for about 5% of man-made climate change effects, and that proportion could triple by 2050 according to some projections. Least understood is the role of aircraft exhausts in forming clouds.
Scientists have discovered that the movement and melting of icebergs plays an important role in distributing phytoplankton and consequently absorbing and removing carbon dioxide from the oceans. The new findings have major implications for global climate research and management.
Decreasing CO2 concentrations in the atmosphere causes more rain to be wrung from the clouds, according to research published in Geophysical Research Letters. That change in rainfall can go both ways, with decreasing precipitation as CO2 levels rise - and it happens faster than the overall global change in temperature.
Spring Opening for old houses that have been transformed into super low emissions properties. What is a SuperHome and does it wear a cape? The answer to that is fairly clear: no it doesn't; in fact a SuperHome looks pretty much like an ordinary home, except it may have solar panels on the roof. It is inside that it is different. SuperHomes are homes that have reduced their their carbon emissions by at least 60%.
According to the new Blue Carbon Working Group, urgent action is needed to halt increasing carbon emissions from destroyed and degraded coastal marine ecosystems. Rapid and long-lasting emissions of CO2 are being released into the ocean and atmosphere due to the destruction of coastal carbon ecosystems, such as mangroves, seagrasses and tidal marshes.
Biofuels produced in Africa but destined for use in Europe will result in up to six times the carbon emissions of fossil fuels, according to a new report. Some species of the succulent Jatropha genus are widely promoted as easily grown crops, and oil from the seeds is used extensively in many developing countries to produce biofuel. However, the new report contradicts the 'green image' of biofuels, which are widely considered to be a renewable alternative to fossil fuels.
Starting 50 million years ago, repeated spikes in temperature pushed life on earth to the brink. Now new research published in Nature has shown that these hyperthermals were more common at that time than originally thought. With these events being linked to massive outpourings of CO2, they may have much to teach us, as we head into the first hyperthermal in tens of millions of years.
A report on the healing potential of Natural Sequence Farming, in repairing wounded carbon and water cycles, has been published in the latest International Journal of Water. Not only can NSF help restore fertility in a sustainable way for the Australian landscape studied - by building up carbon stores in the soil, CO2 is drawn from the atmosphere, so blunting emissions-driven climate change.
Buying local produce can cause more emissions that importing food from abroad. The fact is the energy that goes into produce not indigenous to the local environment can be vastly greater than what is required in the natural country of origin. In order to thrive in the non-indigenous locality, many foodstuffs require the addition of other elements over its life cycle, most notably heat, resulting in higher CO2 emissions than if the produce was transported from the traditional country of origin. Filed under environment: Emissions/Business.
Toyota - makers of the famous Prius - says sales of hybrid vehicles have now passed 3 million, saving the atmosphere from 18 million tons of carbon dioxide. Hybrid dilute the environmental damage a car does by using an electric engine to supplement the power supplied by a traditional internal combustion engine and the Prius was the first mass-produced model.
UK Climate Change Department releases software tool Pathways 2050 to open debate on carbon emissions and energy policy. The UK Department of Energy and Climate Change (DECC) released Pathways to 2050 on their website. It is a piece of software that allows you to reduce British climate emissions by, for example, electrifying the railways or building more wind turbines.
A new report predicts worrying effects on the transpiration of plants. Enjoy basking in the cool shade of an old oak tree in the height of summer? Well, according to American and Dutch scientists it could soon be a less effective way of escaping the heat from the sun. A new study has found that as a result of rising carbon dioxide levels, plants are releasing less water into the atmosphere.
Researchers have found that the effect of soot - rising from the newly industrialised economies of Asia - could have an even more damaging effect on the climate than CO2 in the Himalayas. Researchers at the Department of Energy's Pacific Northwest National Laboratory, the Universityof Michiganand NOAA looked at the effect of soot on the Tibetan Plateau in the Himalayasand found that soot is a worse offender in climate change than CO2.
China's Premier pledged Sunday to cut carbon emissions intensity, by over 16% for the next 5 years. Whilst such a number sounds impressive, when it comes to global warming it's the total emissions that matter. There the story is not so promising. Whilst this pledge is part of a 20-year plan to reduce carbon intensity by 40-45% by 2020, relative to 2005, reducing the intensity of emissions is not the same as reducing total emissions.
Tiny Antarctic organisms are growing more quickly because of an increase in carbon say scientists who used the polar legend's century's old collections. Scientists have been examining tiny creatures called bryozoans. These sea-bed dwellers feed on microscopically small marine plants called phytoplankton, which need carbon dioxide to survive.
By drilling a field in foot wide strips, nine inches deep, and planting maize and adding nitrate fertiliser at the same time, this increases yields and reduces the amount of nitrate escaping into the atmosphere as nitrous oxide. Although carbon dioxide (CO2) is widely held to be the major contributor to global warming, scientists believe that the contribution of nitrous oxide (N2O) is about 300 times more than CO2.
Should droughts in the Amazon Basin become more frequent, the days of the rainforest offsetting man-made carbon emissions are set to come to an abrupt end. The days of the Amazon Rainforest acting as a natural buffer against man-made carbon emissions may be drawing to a close. In fact, not only could the South American forest soon lose its status as the planet's most-important 'carbon sink'
The drive towards electric vehicles pick up speed. China is set to create at least 10 million electric car charging points by 2020. A heavy dependence on foreign oil, plus significant CO2 levels are leading the country to push towards a more environmentally friendly transport infrastructure.
Asking consumers to pay the 'true climate cost' of meat and other dairy products could lead to a severe reduction in carbon emissions, Swedish scientists have argued. While, for the most part, these 'carbon taxes' are levied on businesses operating in the manufacturing and transportation sectors, new research suggests that they could be equally effective, if not more so, if targeted towards the agriculture and food industries.
Air India has announced significant reductions in carbon dioxide emissions after using engine washing technology developed by an American company. The airline says that it has performed 124 washes using Pratt & Whitney's EcoPower technology, saving more than 540,000 gallons of fuel worth $1.9 million and reducing carbon dioxide (CO2) emissions by 5,300 metric tons.
By looking to the past, one team of US scientists believe they can map out the likely changes to the Earth's climate ongoing rises in carbon emissions will bring. one team of US researchers has been looking to the past in order to gain an understanding of the potential consequences of the major rise in the volume of carbon dioxide in the Earth's atmosphere seen since the dawn of the Industrial Revolution. Specifically, the experts at the National Center for Atmospheric Research in Boulder, Colorado, have been asking: When was the last time the Earth's atmosphere contained as much carbon dioxide as it may by the end of this century?
Airline Deutsche Lufthansa has placed a $300 million order with a US-European manufacturer for an aero engine that reduces carbon emissions. The German airline has chosen the CFM56-5B to power 21 Airbus A320 and two Airbus A321 aircraft, attracted by improvements in the engine's operating performances.
How climate change can give a boost to non-native species with potentially devastating results. A recent study indicates that a combination of a warmer world, more extreme weather and higher levels of planet-warming carbon dioxide have the potential to devastate ecosystems.
A collection of new papers welcoming world leaders to Cancun effectively argue that this latest round of climate change talks should be seen almost as a damage limitation exercise. Up to one billion people around the world are set to lose their homes over the next 90 years as a result of ongoing failures to cut back on carbon emissions.
How one UK education organisation reduced CO2 footprint through more efficient use of ICT. A combination of more efficient storage solutions and a remote ICT management system.
Shipping is responsible for 4.5% of global CO2 emissions, double the amount produced by the aviation industry, making the development of reduced emission craft a priority. A study by University of California Riverside of the world's only hybrid electric tugboat confirms the effectiveness of the technology.
A recent U.S. study has discovered that CO2 injected deep underground could bubble up to the surface and contaminate aquifers supplying drinking water.
Greener, lighter packaging will help reduce carbon emissions. If the packaging was made lighter, some of the most climate-damaging effects would be reduced.
A New Zealand wine company is leading the world; proudly displaying the carbon footprint of each glass of wine on their bottles. Consumers are increasingly demanding information on the carbon emissions of their food and drink. The New Zealand Wine Company has launched their new brand Mobius; each bottle has a label declaring the actual carbon emissions for each glass produced.
Charcoal mixed with fertiliser can enhance soil and hold climate changing carbon safely in the ground: Spanish conquistador Francisco del Orellana peered through the Amazon undergrowth. He saw thriving settlements and fertile agriculture along the river. This was 1542. Later visits by other explorers found only jungle and poor soils which could not support agriculture.
The British Government has announced plans to extend its carbon capture and storage (CCS) funding to gas-fired power stations, while the EU has also launched a new programme of funding for green energy projects across the continent.
