According to a report by the Energy Information Administration, wind curtailments in Texas have dropped steadily and substantially since 2011 thanks mostly to the state’s completion of 3,500 miles of transmission lines as part of the Competitive Renewable Energy Zones program.
Conflicts over water have long haunted the Middle East. Yet in the current fighting in Iraq, the major dams on the Tigris and Euphrates rivers are seen not just as strategic targets but as powerful weapons of war.
In 2004, Medellín – the second largest city in Colombia – introduced the Medellín Metrocable system to connect low-income residents to public transport. As the world’s first modern urban aerial cable car transport system, this innovative addition to Medellín’s existing metro system was built in response to significant spatial inequalities in metro access. Metrocable was designed to improve transport and quality of life in informal settlements located on the mountainside, home to some of the city’s most disadvantaged communities. The system currently consists of three lines, the first of which carries approximately 30,000 passengers per day. A recent study further speaks to the system’s success, finding that the Metrocable dramatically improves accessibility to metro stops and employment opportunities for some low-income residents. This attention to the city’s underserved communities reflects Medellín’s increased commitment to improving equity and quality of life while reducing emissions through sustainable mobility.
Global meat production has expanded more than four-fold over the last 50 years — and 25-fold since 1800 — due to growing purchasing power, urbanization, and changing diets, according to a new report from the Worldwatch Institute. Consumers in industrial countries continue to eat much larger quantities of meat (75.9 kilograms per person) than those in developing nations (33.7 kilograms), though that gap is beginning to close, the report says. Nearly 70 percent of the planet's agricultural land and freshwater is used for livestock, with additional land and water used to grow grains for livestock feed. Beef production alone uses about three-fifths of global farmland and yields less than 5 percent of the world's protein, according to the report, and a kilogram of beef requires 15,000 liters of water, versus 3,300 liters for a kilogram of eggs. Sustainable agricultural practices such as feeding livestock with grasses instead of grains and using natural fertilizers could reduce these impacts, the report notes, but alternative dietary choices hold the most immediate promise for reducing the environmental footprint of meat production.
Implementing policies to curb carbon emissions dramatically cuts health care costs associated with poor air quality — in some cases, by more than 10 times the cost of policy implementation, according to new research published in Nature Climate Change. Policies aimed at reducing carbon emissions are as effective as laws targeting polluting compounds like ground-levelRead More
Ljubljana, Slovenia has won the 2016 European Green Capital Award, given annually by the European Commission to cities that set an example of sustainable urban development best practices.
With an ambitious sustainability plan and that has led to significant improvements in the past decade, the capital of Slovenia joins cities such as Bristol, elected as the 2015 winner and Copenhagen, elected as the 2014 winner. The award considers the city’s urban and environmental management strategies and commitment to sustainability. Specifically, the European Commission takes into account indicators such as climate resilience, urban mobility, air quality, waste management, and water quality among other factors.
This post originally appeared at Ensia. “Don’t let fashion go to waste,” says H&M, the global clothing retailer that booked $20 billion in revenue last year. So I brought a bag of old T-shirts, sweaters and khaki pants to an H&M store in Washington, DC, where it took them, no questions asked, and gave me...
Humans risk causing irreversible and widespread damage to the planet unless there’s faster action to limit the fossil fuel emissions that cause climate change, according to a leaked draft United Nations report.
