Reducing Meat and Dairy a ‘Win-Win’ for the Climate and Your Waistline
Consumption of meat and dairy products in many countries has risen beyond healthy levels, the report says and emissions from rearing livestock mean growing meat demand will make it harder to keep global temperature rise below 2C.
Political leaders are “afraid of telling people what to eat,” says the authors, but the findings suggest the public may be less averse to changing their diets than governments fear.
As you can see in the chart below, consumption of meat and dairy products generally increases as a country’s national income rises. While this growth flattens off as earnings climb further, meat eating in many developed countries has plateaued at excessive levels, the report says.
The dotted line shows a healthy level of meat in our diets. On average, in Europe we eat around twice as much as we should, while in the U.S. it’s three times.
This is bad for our waistlines and the climate, the report says.
Our appetite for meat is a major driver of climate change, says lead author Laura Wellesley, a research associate at Chatham House. She told a press conference, "Globally, the livestock sector accounts for 15 percent of all greenhouse gas emissions—that’s equivalent to all exhaust emissions from every vehicle on the planet."
Rearing livestock produces emissions directly from animals, from digestion and manure and from transporting animals and producing their feed. Greenhouse gases are also released when forests are cleared to make way for pasture or for cropland in order to grow animal feed.
Global demand for meat is expected to increase by 76 percent by the middle of this century as both population and incomes rise, Wellesley says, which means emissions are set to rise as well.
Research last year by Chatham House found that without keeping a lid on rising meat and dairy consumption, keeping global temperature rise to 2C above pre-industrial levels was “off the table.” The new report asks how to go about bringing global diets in line with climate emissions targets.
Cycle of Inertia
The issue of how to address meat and dairy consumption has been “trapped in a cycle of inertia,” the report says. Governments have shied away from promoting sustainable diets in fear of a backlash from the public and food industry, while the lack of action means public awareness of the climate impact of meat and dairy is low.
The researchers conducted discussion groups with members of the public in Brazil, China, the U.S. and the UK to explore attitudes to meat and dairy consumption.
The results showed that the public wanted guidance from the government on how much meat they should eat, with participants of the focus groups saying they were unlikely to change their eating habits without it. The report concludes, "Government inaction signals to [the general public] that the issue is unimportant or undeserving of concern."
The findings also suggest that the public may be less reluctant to being asked to cut their meat intake than governments fear. Wellesley explains, "The assumption that interventions like this are too politically sensitive and too practically difficult to implement is unjustified. Our focus groups pointed to a public that expect governments to lead, that expect governments to take action on issues that are in the public interest."
This action could include “nudges” towards more sustainable food choices by improving awareness, food labeling and availability of alternative options. But the most effective method of changing eating behavior is likely to be taxation, the findings suggest.
The Chatham House report doesn’t look into possible tax levels, but research published in the British Medical Journal in 2013 found that taxing the carbon emissions from beef production at £2.72 (USD$4.10) per ton of CO2eq for every 100g of beef would result in a £1.76 (USD$2.65) increase per kilo. This in turn could lead to a 14 percent reduction in consumption.
Although there would be some initial opposition to adding taxes to meat and dairy, public acceptance would come in the long-term, Wellesley says, "Our research also indicates that any backlash to unpopular policies would likely be short-lived."
The public is more likely to accept a tax if they can see the revenues are being redistributed towards other foods, the researchers add.
An Opportunity, Not an Impossibility
So, how much of a difference to global emissions could healthier diets make? Wellesley explains, "A global shift to healthy diets, which for most would mean a reduction of meat consumption—a significant reduction in meat consumption—could bring a quarter of the emissions reductions needed [by 2050] to bring us back online for the 2C target."
You can see this in the chart from the report below. The dark blue line is the future emissions path based on the existing national pledges for cutting greenhouse gases emissions, while the pale blue line shows the reduction if the world shifted to the healthy levels of meat and dairy consumption. The grey line shows the path necessary for 2C.
But you needn’t rush out to stock up on sausages before they disappear from supermarket shelves, says Wellesley, "We’re not in any way advising or advocating for global vegetarianism. It doesn’t need that. You can see a massive change and huge emissions reductions from just converging around healthy levels and moderating our intake."
For example, a study published in Nature Climate Change last year suggested that a global diet of no more than 24g of red meat a day and no more than 85g of chicken, would save six billion tons of CO2e by 2050. For reference, the beef burger in a standard McDonalds hamburger weighs in at 33g.
Cutting back on meat and dairy has a dual benefit of improving global health as well as helping to limit climate change. This makes a “compelling case” for governments to encourage the public to shift their diets, Wellesley concludes, "The key message here is that governments should see dietary change not as impossibility, but as an opportunity."

A stretch of coastline in the Philippine capital, Manila has received backlash from environmentalists. The heavily polluted Manila Bay area, which had been slated for cleanup, has become the site of a controversial 500-meter (1,600-foot) stretch of white sand beach.
Sand Makeup Crucial for Ecosystems<p>While UNEP/GRID-Geneva generally supports finding <a href="https://www.dw.com/en/not-enough-sand-for-construction-industry-despite-abundance/a-49342942" target="_blank" rel="noopener noreferrer">alternative sources of sand</a> so as not to disrupt ecosystems in rivers and oceans when extracting them, Vander Velpen stressed it was vital to use sand which closely matches the makeup of the native sand to protect beach fauna.</p><p>"If you change the core characteristics of the native sand, the original sand, you need to do an environmental impact assessment (EIA) to find out how it's going to impact the ecosystem and nearby ecosystems," he told DW.</p><p>But according to Torres, such an assessment was not done in Manila.</p>
Beautification Stunt Instead of Proper Cleanup?<p>Manila Bay's waters are heavily polluted by oil and trash from nearby residential areas and ports. A huge "No swimming" sign warns visitors to stay away from the ocean.</p><p>Philippines' <a href="https://denr.gov.ph/index.php/priority-programs/manila-bay-clean-up/25-priority-programs/1825-frequently-ask-questions-faqs-on-the-dolomite-and-the-beach-nourishment-project" target="_blank">Department of Environment and Natural Resources (DENR)</a> has denied dolomite sand poses any risk to human health and the ecosystem.</p><p>However, scientists of the University of the Philippines have come forward disputing the DENR's claims. A <a href="https://biology.science.upd.edu.ph/index.php/ib-statement-regarding-dolomite-in-manila-bay/" target="_blank" rel="noopener noreferrer">statement by the Institute of Biology</a> said that using crushed dolomite did not address any of the rehabilitation phases and instead was "even more detrimental to the existing biodiversity as well as the communities in the area," pointing to the case of water birds. "The dumping of dolomite in Manila Bay has effectively covered part of the intertidal area used by the birds thereby reducing their habitat."</p><p>At peak migration season, Manila Bay is home to 90 aquatic bird species, including species of international conservation concern that are facing a very high extinction risk in the wild. </p><p>Authorities should focus on protecting and conserving biodiversity, the Institute of Biology added. "Rehabilitating mangroves is an example of a nature-based solution that is cheaper and more cost-effective than the dolomite dumping project," the scientists said.</p><p>Moreover, <a href="http://www.msi.upd.edu.ph/" target="_blank" rel="noopener noreferrer">the Marine Science Institute</a> has warned that prolonged inhalation of finer dust particles of dolomite could "cause chronic health effects," leading to discomfort in the chest, shortness of breath and coughing.</p><p>They also warned dolomite sand grains would erode during storms and be carried out to sea, essentially being washed away.</p>
Rehabilitation vs. Reclamation<p>Environmentalists say covering up the beach doesn't address the real issues of the bay. Torres and others believe the best way to clean up Manila Bay is not to add anything, but rather remove trash and pollution.</p><p>"There have been studies saying much of the waste comes from already collected waste — so these are open dump sites along the coast that get washed up because of the rain," Torres said.</p><p>She criticized the authorities for continuing to push reclamation projects she says are at odds with each other. These projects will affect large areas of mangrove forests, she said, and experts warn that this, in turn, exacerbates coastal erosion.</p><p>"If you've removed the areas that helped trap the sand, like mangrove forests, then the likelihood increases that you will have to nourish a beach. Same as building right up to the waterfront," said Vander Velpen of UNEP/GRID-Geneva.</p>
Plenty of Sand in the Sea?<p>The question of Manila's contentious white beach echoes larger questions about sand mining worldwide. <a href="https://unepgrid.ch/storage/app/media/documents/Sand_and_sustainability_UNEP_2019.pdf" target="_blank">Global sand consumption has tripled</a> over the past two decades, UNEP/GRID-Geneva has found. A huge chunk of it is now taken up by construction.</p><p>"Many operate on the assumption that natural sand is endless in its supply," said Vander Velpen.</p><p>Sand scarcity is a concern shared by Stefan Schimmels of <a href="https://www.fzk.uni-hannover.de/fzk_start.html?&L=1" target="_blank">Forschungszentrum Küste</a> who's done extensive research on shore nourishment to stop coastal erosion. And as climate change and rising sea levels are threatening coasts, demand for sand will grow even more.</p><p>A large study, the <a href="http://www.stencil-project.de/wp-content/uploads/2019/10/STENCIL_SWOT_Analyse_191026.pdf" target="_blank">Strategies and Tools for Environment-Friendly Shore Nourishments as Climate Change Impact Low-Regret Measures (STENCIL project)</a>, focused on the German island of Sylt, a popular vacation spot.</p><p>About 1 million cubic meter of sand per year is used to maintain the coastal area of Sylt, STENCIL project head Schimmels said. That's about 100 million 10-liter buckets of sand.</p><p>When sand was extracted off the coast of Sylt, underwater craters were formed. "You can still detect these craters even decades later," Schimmels told DW.</p><p>"Also when you add a couple of meters sand onto the beach — you essentially bury all things that do creep and fly," he said. "How quickly will they recover?" Schimmels said more research was needed as there was still too little known about long-term effects on the environment. </p>
Criticism Piling Up<p>As for Manila's artificial white sand, it looks like some might have already been blown away by a recent storm. DENR claims it wasn't washed away, but said that grayish sand, stones and other material had simply piled up over the dolomite sand. People in Manila have tweeted photos showing how the storm has ravaged the beach. </p>
