Eating
less meat essential to curb climate change, says report
Global
livestock industry produces more greenhouse gas emissions than
transport but fear of a consumer backlash is preventing action, says
Chatham House report

Curbing the world’s
huge and increasing appetite for meat is essential to avoid
devastating climate change, according to a new report. But
governments and green campaigners are doing nothing to tackle the
issue due to fears of a consumer backlash, warns the analysis from
the thinktank Chatham House.
The global livestock
industry produces more greenhouse gas emissions than all cars,
planes, trains and ships combined, but a worldwide survey by Ipsos
MORI in the report finds twice as many people think transport is the
bigger contributor to global warming.
“Preventing
catastrophic warming is dependent on tackling meat and dairy
consumption, but the world is doing very little,” said Rob Bailey,
the report’s lead author. “A lot is being done on deforestation
and transport, but there is a huge gap on the livestock sector. There
is a deep reluctance to engage because of the received wisdom that it
is not the place of governments or civil society to intrude into
people’s lives and tell them what to eat.”
The recent landmark
report from the Intergovernmental Panel on Climate Change found that
dietary change can “substantially lower” emissions but there is
no UN plan to achieve that.
Past calls to cut
meat eating by high-profile figures, from the chief of the UN’s
climate science panel to the economist Lord Stern, have been both
rare and controversial. Other scientists have proposed a meat tax to
curb consumption, but the report concludes that keeping meat eating
to levels recommended by health authorities would not only lower
emissions but also reduce heart disease and cancer. “The research
does not show everyone has to be a vegetarian to limit warming to 2C,
the stated objective of the world’s governments,” said Bailey.
The report builds on
recent scientific studies which show that soaring meat demand in
China and elsewhere could tip the world’s climate into chaos.
Emissions from livestock, largely from burping cows and sheep and
their manure, currently make up almost 15% of global emissions. Beef
and dairy alone make up 65% of all livestock emissions.
Appetite for meat is
rocketing as the global population swells and becomes more able to
afford meat. Meat consumption is on track to rise 75% by 2050, and
dairy 65%, compared with 40% for cereals. By 2020, China alone is
expected to be eating 20m tonnes more of meat and dairy a year.
Two recent
peer-reviewed studies calculated that, without severe cuts in this
trend, agricultural emissions will take up the entire world’s
carbon budget by 2050, with livestock a major contributor. This would
mean every other sector, including energy, industry and transport,
would have to be zero carbon, which is described as “impossible”.
The Chatham House report concludes: “Dietary change is essential if
global warming is not to exceed 2C.”
The consumer survey
in the report, covering 12 nations including the US, China, India,
Brazil and the EU bloc, found a link between the awareness of climate
change and its impacts and the willingness to change behaviour.
Acceptance that human activities cause climate change was
significantly higher in China, India and Brazil than in the US, UK
and Japan.
The good news, said
Bailey, was that “the majority of future demand appears to be in
the countries [like China and Brazil] that are the most receptive to
change”. He said it was “pretty disappointing” that in
developed countries, where meat and dairy eating is highest,
awareness of livestock’s impact on the climate is low and
willingness to change is low.
Brigitte Alarcon,
sustainable food policy officer at WWF said: “Our LiveWell project
has shown we can cut a quarter of our climate emissions from the
European food supply chain by eating more pulses, fruit and
vegetables and by reducing our meat consumption. National governments
should improve food education to encourage healthy eating habits and
environmental sustainability as a first step.”
A spokesman for the
UK government said: “Greenhouse gas emissions from the UK
agricultural industry have fallen by more than 20% since 1990. While
food choices can have an impact on emissions, well managed livestock
also provide many environmental benefits including supporting
biodiversity.”
A separate survey by
the Eating Better alliance, also published on Wednesday, shows that
UK consumers are beginning to eat less meat. The YouGov poll found
20% saying they have cut the amount of meat they eat over the last
year, with only 5% say they are eating more.
Prof Keith Richards,
at the University of Cambridge and one of the researchers behind the
two key scientific studies, said: “This is not a radical vegetarian
argument; it is an argument about eating meat in sensible amounts as
part of healthy, balanced diets.”
