It is difficult for me to understand why more environmentalists don't talk more positively about veganism, especially with regard to climate change. The facts in support of reducing meat and dairy use are overwhelming. A UN report from way back in 2006 found that livestock produces 18 percent more greenhouse gas emissions from CO2 than from from transport (
source). A new study from the World Preservation Foundation was recently discussed on the
Freakonomics.com website. Some of the findings from WPF include:
- Eating vegan more beneficial than driving
a hybrid.
In 2006, a University of Chicago, US, report
concluded a person adopting a vegetarian
diet for a year would reduce more emissions
than someone swapping their regular car for
a Toyota Prius.
- Livestock emissions higher than transport
emissions. In 2006, the Livestock group
within the UN‟s Food and Agriculture
Organization released Livestock’s Long
Shadow, estimating livestock to be
responsible for 18 percent of global
emissions:
more than all transportation combined.
- A vegan diet reduces emissions 7 times
more than local eating.
In 2008, Carnegie Mellon University
compared the emissions from consuming a
diet of 100% locally grown food to one of
100% plant-foods, concluding a vegan diet
led to a reduction of seven times the
emissions of a locally-grown diet because
most dietary emissions are in operations, not
transportation.
- An organic vegan diet reduces 94% of
dietary emissions vs. 8% for sustainable
meat & dairy. In 2008, Germany's
Foodwatch Institute estimated shifting from
a conventional diet, including meat and
dairy, to a conventionally-raised vegan diet
would reduce emissions by 87 percent, while
shifting to an organic diet including meat
and dairy would only reduce emissions by 8
percent. By contrast, a 100% organic vegan
diet would reduce emissions by 94 percent.
