Columbus Dispatch: Those big, sprawling, suburban homes might seem appealing for the space, the lawns or the schools. But the environmental cost of households there are much greater than their urban counterparts, according to a new analysis. Community Research Partners, a Columbus nonprofit group, found that the average household in New Albany created more than twice the greenhouse gas emissions than the average household in Downtown Columbus. (New Albany had the greatest carbon footprint, and Downtown had the smallest...

Diesel cars may be be worse than petrol for CO2 emissions, report claims
2016-02-19 16:56:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Diesel engines may be doing nothing to slow global warming despite being the backbone of Europes policy to reduce car emissions, a new report claims. Tailpipe emissions of sooty black carbon could be as much as 25-50% higher than the EU estimates for cars made before 2005, says the paper by Professor Erckard Helmers of Triers University. On this analysis, some 20m cars in use since the 1990s may each have produced 40-80g of CO2 equivalent per kilometre more than previously thought. However,...

Harvard Study: U.S. Likely Culprit Global Spike Methane Emissions
2016-02-18 16:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Common Dreams: New research has linked the U.S. to the massive rise in global methane emissions. Bobby Magill reported on the Harvard University study on Climate Central Tuesday. Using satellite data, the researchers found that methane emissions in the country rose more than 30 percent over the 20022014 period and that increase "could account for 3060 percent of the global growth of atmospheric methane seen in the past decade," the study`s abstract states. Though the study does not attribute the increase...

How To Reduce Methane Emissions With Thermal Mass Flow Meters
2016-02-18 09:51:29| oilandgasonline Home Page
The flare gas discussion is heating up again. According to the Bureau of Land Management (BLM), U.S. oil production is at an all-time high, and so are the harmful methane emissions from leaks, flaring and venting. U.S. Secretary of the Interior Sally Jewell has proposed to update 30-year-old regulations in order to reduce the excess release of natural gas into the atmosphere from oil and gas operations on public and American Indian lands.
