Concrete jungle functions as carbon sink
November 22, 2016 07:03 AM - UCI News
Cement manufacturing is among the most carbon-intensive industrial processes, but an international team of researchers has found that over time, the widely used building material reabsorbs much of the CO2 emitted when it was made.
Airlines to Test Alternative Fuel
October 12, 2016 06:35 AM - Anum Yoon, Triple Pundit
As the world turns its attention to addressing global warming, the airline industry, too, is researching ways to do its part and lower greenhouse gas emissions. One option is investing more into the development and integration of alternative fuels. Biofuels made from vegetable oil, corn and even household garbage are all very real possibilities.
Recycling on the ropes, France has a plan to fix the industry
January 11, 2016 05:29 AM - EurActiv
Low raw material costs have dealt a heavy blow to the recycling industry. The French recycling federation (FEDEREC) believes the sector needs a complete overhaul to stay afloat in the coming years.
FEDEREC published its view of the future of recycling in a white paper entitled "The recycling industry by 2030." In the preface to this 70-page document, a frank discussion of the problems facing the industry and how they might be solved, Corinne Lepage, a Republican politician, evoked a sector "devastated by an oil price that is so low that it is driving us back towards a linear economy, as it is cheaper today to buy primary raw materials than recycled raw materials".
Solar gaining on coal in India
January 4, 2016 06:15 AM - Chris Goodall, Ecologist
A KPMG study shows that the cost of solar power in India, revealed by public auctions, is barely half a cent above that of cheap local coal , writes Chris Goodall, with generators bids falling well below 5p (UK) / 7¢ (US) per kWh. The idea put about at COP21 that India and other poor but sunny countries need coal to develop their economies is fast running out of steam.
When the accountants have fully loaded the network and other costs PV ends up as very slightly cheaper than using lndian-mined coal. And, of course, this advantage will grow as solar gets cheaper.
Commentators eager to arrest the move towards renewable energy are facing increasing difficulties finding arguments for the continued use of fossil fuel.
2015 Year in Review
December 31, 2015 07:10 AM - Mike Gaworecki, MONGABAY.COM
As 2015 comes to a close, Mongabay is looking back at the year that was. This year saw President Obama reject the Keystone pipeline as historic droughts and a vicious wildfire season wracked the western US and Canada. The world committed to climate action in Paris as Southeast Asia was choking on the worst Indonesian haze in years, Shell aborted its plans to drill in the Arctic for the “foreseeable” future, and ExxonMobil is being investigated for lying to the public about climate risks. Here, in no certain order, are the top 15 environmental stories of 2015.
Wind power on the rise in U.S.
December 22, 2015 07:22 AM - Jeff Brady, NPR
The U.S. wind power industry is celebrating after reaching a new milestone in November: 70 gigawatts (GW) of generating capacity.
"That's enough to power about 19 million homes," says Michael Goggin, senior director of research at the American Wind Energy Association (AWEA).
Rapid plankton growth seen as indicator of carbon dioxide loading in oceans
November 27, 2015 08:04 AM - Arthur Hirsch, Johns Hopkins
A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found.
What these findings mean remains to be seen, as does whether the rapid growth in the tiny plankton's population is good or bad news for the planet.
Published today in the journal Science, the study details a tenfold increase in the abundance of single-cell coccolithophores between 1965 and 2010, and a particularly sharp spike since the late 1990s in the population of these pale-shelled floating phytoplankton.
Canada ranks #2 for most LEED buildings
July 28, 2015 01:24 PM - Roy L Hales, ECOreport
Though LEED is not the world’s only green building rating system, it is the most widely used and recognized. Thus it is no small thing that, for the second year in a row, Canada is #2 for LEED building in the World.
Aircraft may be lessening their carbon footprint, but what about airports?
June 22, 2015 08:47 AM - Timothy Spence, EurActiv
Today’s passenger aircraft are becoming ever more efficient, driven by regulations like the EU’s emissions trading scheme and airlines looking to squeeze profit out of every drop of fuel saved. Yet on the ground, airports operate in a different class. New findings from a European Union-funded research project show that commercial airports use as much energy as a small city, and up to one-fifth of that may be wasted.
Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.
