Emissions from energy-rich Norway on the decline

Emissions from energy-rich Norway on the decline

Business
Aug. 15 (UPI) -- The Norwegian government reported Wednesday that total greenhouse gas emissions were lower, with declines in pollution from road traffic leading the way. Statistics Norway, the government's record-keeping agency, published data showing total greenhouse gas emissions declined in 2017 by 1.7 percent from the previous year. By sector, manufacturing and mining had the greatest increase with 4.3 percent from 2016, while emissions from road transportation had the greatest decrease with 9.6 percent. There were 142,490 total electric cars registered in the country at the beginning of the year, up more than 40 percent from one year ago. Passenger vehicles made up 97 percent of that total. The Norwegian government said electric vehicles make up about 5 percent of the passenger flee...
Climate change: 'Hothouse Earth' risks even if CO2 emissions slashed

Climate change: 'Hothouse Earth' risks even if CO2 emissions slashed

World
It may sound like the title of a low budget sci-fi movie, but for planetary scientists, "Hothouse Earth" is a deadly serious concept.Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.Even if countries succeed in meeting their CO2 targets, we could still lurch on to this "irreversible pathway". Their study shows it could happen if global temperatures rise by 2 deg C.An international team of climate researchers, writing in the journal, Proceedings of the National Academy of Sciences, says the warming expected in the next few decades could turn some of the Earth's natural forces - that currently protect us - into our enemies. Each year the Earth's forests, oceans and land soak u...
VW fined €1.2bn over diesel emissions scandal

VW fined €1.2bn over diesel emissions scandal

Business
The emissions scandal that engulfed Volkswagen three years ago continues to dog the carmaking giant, as German authorities hit the group with a €1.2bn fine. Volkswagen has said that prosecutors in the German city of Braunschweig levied the £880m fine, saying the carmaker failed to properly oversee its engine development department's activities, resulting in about 10.7m diesel vehicles with illegal emissions-controlling software being sold worldwide.The firm said it hoped that paying the fine would have "positive effects on other official proceedings being conducted in Europe against Volkswagen" and its subsidiaries.:: VW Group set to 'recall up to 28,000' Volkswagens and Seats over seatbelt issue Image: Reacquired Volks...
Mysterious rise in emissions of ozone-damaging chemical

Mysterious rise in emissions of ozone-damaging chemical

Science
Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC) highly damaging to the ozone layer.Banned by the Montreal Protocol in 1987, CFC-11 was seen to be declining as expected but that fall has slowed down by 50% since 2012.Researchers say their evidence shows it's likely that new, illegal emissions of CFC-11 are coming from East Asia.These could hamper the recovery of the ozone hole and worsen climate change.CFC-11 is also known as trichlorofluoromethane, and is one of a number of CFCs that were initially developed as refrigerants during the 1930s. They were also used as propellants in aerosol sprays and in solvents. However, it took many decades for scientists to discover that whe...
Sentinel tracks ships' dirty emissions from orbit

Sentinel tracks ships' dirty emissions from orbit

Science
The new EU satellite tasked with tracking dirty air has demonstrated how it will become a powerful tool to monitor emissions from shipping. Sentinel-5P was launched in October last year and this week completed its in-orbit commissioning phase. But already it is clear the satellite's data will be transformative. This latest image reveals the trail of nitrogen dioxide left in the air as ships move in and out of the Mediterranean Sea. The "highway" that the vessels use to navigate the Strait of Gibraltar is easily discerned by S5P's Tropomi instrument. "You really see a straight line because all these ships follow approximately the same route," explained Pepijn Veefkind, Tropomi's principal investigator from the Dutch met office (KNMI). "In this case, we also looked into how many big ships th...
