26 June 2016, Climate News Network, China aims to halve meat eating.The Chinese government has issued guidelines to help wean its citizens onto a more vegetarian diet − offering huge potential health gains and cuts in greenhouse gases. In a bold challenge to individual appetites and societal norms, China says it wants to reduce its citizens’ consumption of meat by 50%. The country consumes 28% of the world’s meat, including half of its pork, although its per capita consumption is much less than in at least 14 other countries. The average American or Australian eats twice as much meat as the typical Chinese citizen. The Chinese health ministry has published new dietary guidelines recommending that people should eat from 40g to at most 75g of meat a day, which is close to the level recommended by British health authorities to limit the risk of developing bowel cancer. The guidelines’ main purpose is to improve public health, but if they achieve their aim they will also give a significant boost to efforts to cut emissions of the greenhouse gases (GHGs) that are stoking climate change and global warming. Livestock emissions Worldwide, 14.5% of greenhouse emissions come from the livestock industry, which is more than the contribution from the entire transport sector. Livestock emit the highly-potent greenhouse gas methane, although there have been proposals to tackle the problem by changing the animals’ diets. Land clearing, fertilisers and slurry also release large quantities of GHGs. The new guidelines could mean carbon dioxide equivalent emissions from China’s livestock industry would fall by 1bn tonnes by 2030, from a projected 1.8bn tonnes in that year. Read More here

22 June 2016, Reuters, Court strikes down Obama fracking rules for public lands. A federal judge has struck down the Obama administration’s rules for hydraulic fracturing on public lands, a victory for oil and gas producers and state regulators who opposed the rules as an egregious overreach. The ruling, which the White House vowed to appeal, halts the administration’s efforts to address what it sees as safety concerns in the industry and reverses what producers had seen as a first step toward full federal regulation of all fracking activity. The U.S. Interior Department’s Bureau of Land Management (BLM) lacked Congressional authority to set fracking regulations for federal and Indian lands, U.S. District Judge Scott Skavdahl in Wyoming ruled late on Tuesday. BLM’s rules, issued in their final form in March 2015, would have required companies to provide data on chemicals used in hydraulic fracturing and to take steps to prevent leakage from oil and gas wells on federally owned land. Fracking, currently regulated by states, involves injection of large amounts of water, sand and chemicals underground at high pressure to extract oil or natural gas. Environmental groups and some neighbors of oil and gas wells have linked fracking to water pollution as well as increased earthquake activity in certain areas. Because most fracking in the United States takes place on private land, the case had little direct effect on existing operations. Roughly 22 percent of U.S. oil production comes from federal lands, with much of that from offshore Gulf of Mexico production, not shale fields. Still, oil producers had feared the new regulations would be a step toward federal oversight of all fracking. “This ruling sends a broad signal about who really does have the jurisdictional authority to regulate this area,” said Ryan Sitton of the Railroad Commission of Texas, which oversees the oil and gas industry in the top producing state.

13 June 2016, The Conversation, The hidden energy cost of smart homes. Light globes that change colour with the tap of an app, coffee machines you can talk to, and ovens that know exactly how long to cook your food: our homes are getting smart. These devices, just a few examples of what is known as “the internet of things” (or IOT), have been called the “next great disruptor” and “the second digital revolution”. One of the great hopes of this revolution is that it will help households save energy. Sensors can turn off lights and appliances when not in use, or turn the heating down when people go to bed. Smartphone apps can provide households with more insight into the energy use of their appliances. While estimates vary widely, industry proponents suggest that emerging connected home technologies could help households reduce their energy bills by 10-25%. Such claims are largely speculative given the absence of robust “before and after” research. Social research from Australia and the UK is revealing ways in which IOT might also increase energy demand. We have identified three “hidden” energy impacts which are rarely considered in IOT research or energy-saving predictions. New updates and hardware Read More here
April 2016 GrowthBusters: Great news about progress in questioning the worship of perpetual economic growth! The UK Parliament has officially convened an “All-Party Parliamentary Group on Limits to Growth.” This collection of members of the House of Commons and the House of Lords will “create the space for cross-party dialogue on environmental and social limits to growth; assess the evidence for such limits, identify the risks and build support for appropriate responses; and contribute to the international debate on redefining prosperity.” This should be headline news around the world. I’ve always said elected officials will be the last to adopt 21st century thinking about true sustainability – especially the unsustainability of economic growth; it appears they are finally getting on the bus. This is a truly significant step. Be sure to check out the new publication prepared for this launch, Limits Revisited: A Review of the Limits to Growth Debate.
