If you thought eating only “grass-fed” hamburgers could absolve you from climate change guilt, think again. There’s a lack of evidence that livestock (such as cattle, sheep, and goats) dining on grassland has a lower carbon footprint than that fed on grains, as some environmentalists and “pro-pastoralists” claim, according to a new report [Grazed and Confused] by an international group of researchers led by the Food Climate Research Network (FCRN), based at the University of Oxford in the United Kingdom.
“Switching to grass-fed beef and dairy does not solve the climate problem—only a reduction in consumption of livestock products will do that,” says one of the report’s authors, Pete Smith of the University of Aberdeen in the United Kingdom.
Livestock is responsible for 14.5% of global greenhouse emissions, researchers estimate. The animals emit gases such as nitrous oxide, carbon dioxide (CO2), and methane in amounts that have significantly changed our atmosphere. And the impact is growing. As more people worldwide are lifted out of poverty, many more can afford to eat meat regularly; global demand for animal products, now 14 grams per person per day, is expected to more than double by 2050.
BOSTON – The Baker-Polito Administration today announced the Commonwealth has been named the most energy efficient state in the nation by the American Council for an Energy-Efficient Economy (ACEEE) for the seventh consecutive year. Massachusetts continues to receive top marks for its energy efficiency policies and programs, particularly the energy efficiency programs offered by the Commonwealth’s utilities under the Mass Save® brand and for promoting smart growth development in cities and towns. The full 2017 ACEEE State Energy Efficiency Scorecard can be found here.
Earth Overshoot Day marks the date each year when humanity’s demand for ecological resources and services exceeds what our planet can regenerate in a year. This year that date is August 2, six days earlier than in 2016 and the earliest ever since these calculations began.
In concert with 2017 Earth Overshoot Day, Global Footprint Network has launched a new mobile-friendly calculator that individuals can use to measure and assess their own ecological footprint. Calculate your own personal overshoot day and find out how many planets it takes to support your lifestyle.
