The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.
India submitted its long-awaited climate pledge on Thursday, vowing to reduce the intensity of its emissions 33 to 35 percent below 2005 levels by 2030.
India is last of the major carbon emitters to reveal its pledge in advance of the global climate talks scheduled for December in Paris. And unlike the other largest countries, it did not promise to cap its emissions. Instead, the Indian government outlined a host of renewable energy projects, mitigation and adaptation strategies and policy initiatives designed to achieve its target. It also estimated that it will require $2.5 trillion to follow through on its pledge.
TransCanada is forced to drop its eminent domain claims to run the controversial tar sands pipeline through private lands.
TransCanada, the company behind the Keystone XL pipeline, has pulled out of a lawsuit launched by Nebraska landowners who oppose the project. The move ensures another delay of seven to 12 months in the Nebraska review process as the company seeks a legally approved route through the state.
ExxonMobil has been hit with a $2.6 million fine and harshly criticized by federal safety officials for failing to maintain an aging oil pipeline that burst two years ago in a quiet Arkansas neighborhood and sent heavy crude oil flowing through the streets.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) also faulted the company for its failure to spot warning signs that its 65-year-old Pegasus pipeline had structural defects that led to the rupture in Mayflower, Ark., a small community about 25 miles north of Little Rock, in March 2013.
Increased greenhouse gas emissions from the release of carbon dioxide and methane contained in the Arctic permafrost could result in $43 trillion in additional economic damage by the end of the next century, according to researchers from the University of Cambridge and the University of Colorado. In a letter published today (21 September) in the journal Nature Climate Change, the researchers have for the first time modelled the economic impact caused by melting permafrost in the Arctic to the end of the twenty-second century, on top of the damage already predicted by climate and economic models.
King crabs may soon become high-level predators in Antarctic marine ecosystems where they haven’t played a role in tens of millions of years, according to a new study led by Florida Institute of Technology. “No Barrier to Emergence of Bathyal King Crabs on the Antarctic Shelf,” published online in the Proceedings of the National Academy of Sciences, ties the reappearance of these crabs to global warming.
In a study published today in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere. “The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with tremendous quantities of lower-cost goods,” said co-author Steven J. Davis, an assistant professor of Earth system science at the University of California, Irvine. “But all of this has come at substantial cost to the environment.”
The researchers, also from Harvard University and the University of Maryland, attribute China’s high emissions intensity – the quantity of CO2 emitted per dollar of goods produced – to the nation’s antiquated manufacturing processes and reliance on coal.
At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
