Led by VTT, the EU North State project has developed a new method of using satellite images to evaluate the forest carbon balance. The carbon balance indicates how much carbon is sequestered or released by forests each year. This enables the carbon balance to be displayed on digital maps, with an accuracy of up to ten metres.

A UBC researcher is drawing attention to the human cost of our consumer behaviour by examining the number of deaths caused by air pollution from manufacturing goods. While some countries bear the brunt of the health risks from air pollution, the products often end up in the hands of consumers in other countries.

Potentially explosive methane gas leaking from energy wells may travel extensively through groundwater and pose a safety risk, according to a new study by University of Guelph researchers.

New research from the University of Minnesota points to lawn fertilizers and pet waste as the dominant sources of nitrogen and phosphorus pollutants in seven sub-watersheds of the Mississippi River in Saint Paul, Minnesota.

A new U.S. Geological Survey interactive map provides a comprehensive, long-term look at changes in the quality of our nation’s rivers and streams over the last four decades. For the first time, monitoring data collected by the USGS and 73 other organizations at almost 1,400 sites have been combined to provide a nationwide look at changes in the quality of our rivers and streams between the 1972 passage of the Clean Water Act and 2012.

Aerosols are collections of fine particles, either biological or of other types, in suspension in a gaseous medium. They play a major role in cloud formation and therefore have a strong impact on climate models. They are however extremely hard to study due to the small size and immense variety of their constituent particles. But researchers from the University of Geneva (UNIGE), Switzerland, members of the PlanetSolar Deepwater expedition, have now succeeded in linking the composition of marine biological aerosols - and therefore their influence on the climate - to that of bodies of water under them within the Atlantic Ocean, thereby paving the way to an indirect study of these aerosols through water analysis. This study, which has been published in Scientific Reports, will contribute to making climate models more accurate.

Installing green infrastructure in residential neighbourhoods can reduce stormwater run-off, mitigating the effects of climate change on sewer systems, says Zach McPhee.

A new class of carbon nanotubes could be the next-generation clean-up crew for toxic sludge and contaminated water, say researchers at Rochester Institute of Technology.

Enhanced single-walled carbon nanotubes offer a more effective and sustainable approach to water treatment and remediation than the standard industry materials—silicon gels and activated carbon—according to a paper published in the March issue of Environmental Science Water: Research and Technology.

Climate change has dominated the news over the past 15 months. First, nearly 200 nations signed a historic accord in Paris during the COP21 climate talks in December 2015. The signatories to the accord, including the United States, the countries of the European Union, China and India, agreed to do their part to cut carbon emissions, and the Paris agreement entered into force months ahead of schedule. 

A type of bacteria accidentally discovered during research supported by the Engineering and Physical Sciences Research Council (EPSRC) could fundamentally re-shape efforts to cut the huge amount of electricity consumed during wastewater clean-up.

The discovery has upended a century of conventional thinking. The microorganisms - 'comammox' (complete ammonia oxidising) bacteria - can completely turn ammonia into nitrates. Traditionally, this vital step in removing nitrogen from wastewater has involved using two different microorganisms in a two-step approach: ammonia is oxidised into nitrites that are then oxidised into nitrates, which are turned into nitrogen gas and flared off harmlessly.
