Researchers convert carbon dioxide into a valuable resource
Researchers at Aalto University have opened a pilot plant that converts CO2 and slag, the by-product of steel manufacturing, into a valuable mineral product. The product, Precipitated Calcium Carbonate (PCC), ...
Global shift away from cars saves US$100 trillion, eliminates 1,700 MT of CO2 pollution
More than $100 trillion in cumulative public and private spending, and 1,700 megatons of annual carbon dioxide (CO2)—a 40 percent reduction of urban passenger transport emissions—could be eliminated by 2050 if the world ...
Fossil-fuel emissions unbraked by financial crisis
Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday.
Iron fertilisation would 'significantly' change deep-sea ecosystems
Adding iron to the oceans in an effort to curb growing emissions of carbon dioxide (CO2) in the atmosphere would lead to 'significant changes' in deep-sea ecosystems, the latest study suggests.
Climate change plays 'Russian roulette' with the world's oceans
The world's oceans will see dramatic changes thanks to climate change, affecting hundreds of millions of people who depend on the sea according to research published today in the online journal PLOS Biology. It's the first global forecast for the oceans under clim ...
Consumption, carbon emissions and international trade
Accurately calculating the amount of carbon dioxide emitted in the process of producing and bringing products to our doorsteps is nearly impossible, but still a worthwhile effort, two Carnegie researchers claim in a commentary ...
Researchers look to carbon dioxide as a more environmentally friendly refrigerant gas
Keeping food fresh is no easy feat. Trials of transporting ice over long distances and the hazards of systems that rely on toxic gases riddle the pages of refrigeration history. And although cooling science ...
Jatropha Helps Air New Zealand Cut Its CO2 Emissions by More Than 60%
Greenhouse gas levels in atmosphere hit new high, UN reports
Surging levels of carbon dioxide sent greenhouse gases in the atmosphere to a new record in 2013, while oceans, which absorb the emissions, have become more acidic than ever, the UN said on Tuesday.
EU cuts CO2 emissions for vans by 28%
European Parliament signed off Tuesday on new carbon dioxide restrictions for commercial vans that will slash emissions by 28 percent from 2020.
Study maps 15 years of carbon dioxide emissions on Earth
World leaders face multiple barriers in their efforts to reach agreement on greenhouse gas emission policies. And, according to Arizona State University researchers, without globally consistent, independent ...
Morphing is one way to make aircraft more efficient
It is estimated that by 2050 there will be a six-fold increase in the number of flights there are today. This is going to be an environmental problem, and it will need radical change in aircraft design to ...
Researchers warn against high emissions from oil palm expansion in Brazil
Expanding millions of hectares of Brazilian land to produce palm oil for food or for renewable, clean-burning biodiesel could result in extremely high emissions of carbon dioxide (CO2) unless strict controls are put in place.
US scientists report big jump in heat-trapping CO2 (Update)
The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees (1.2 C) as many global leaders have hoped, new federal figures ...
