Hundreds of academics call for 100% plant-based meals at UK universities

Damian Carrington, The Guardian, Sept. 4, 2023

fight the climate crisis, saying that the institutions have “for centuries, been shining lights of intellectual, moral, and scientific progress”.

The open letter, organised by the student-led Plant-Based Universities campaign, likened the move to meat-free food to the fossil fuel divestment to which 101 UK universities have already committed.

Cutting meat consumption in rich nations is vital to tackling the climate crisis, with scientists saying it is the single biggest way for people to reduce their impact on the planet.

The letter, sent to UK university vice-chancellors, catering managers, and student union presidents, said: “We are acutely aware – as you must be too – of the climate and ecological crises; not only this but we are also mindful that animal farming and fishing are leading drivers of them.

“Most universities have declared a climate emergency, with many taking steps such as fossil fuel divestment. [Students] deserve to know that their universities are actively working to create a future for them to graduate into.”….

The Plant-Based Universities campaign is active in more than 50 universities. To date, the student unions’ at Birmingham, University College London, Stirling, and Queen Mary universities have voted to phase in 100% plant-based menus.

Related votes also have passed at Cambridge, Kent and London Metropolitan universities. Votes at Edinburgh and Warwick universities did not pass. The University of Cambridge removed beef and lamb from the menus of its 14 catering outlets in 2016, “dramatically reducing food-related carbon emissions”.

Chris Packham said: “The student campaigners of Plant-Based Universities are making incredible changes in their institutions and it’s only right to see hundreds of academics stepping up to support them.”

In 2020, A powerful coalition of the UK’s health professions said the climate crisis could not be solved without action to cut the consumption of high-emission food such as red meat, and that sustainable diets were healthier.

Public sector caterers serving billions of meals a year in schools, universities, hospitals and care homes also pledged in 2020 to cut the amount of meat they serve by 20%. In 2021, a government-commissioned national food strategyrecommended cutting meat consumption by nearly a third.

Vegan diet massively cuts environmental damage, study shows

Detailed analysis finds plant diets lead to 75% less climate-heating emissions, water pollution and land use than meat-rich ones

Damian Carrington, The GuardianJuly 20, 2023

Eating a vegan diet massively reduces the damage to the environment caused by food production, the most comprehensive analysis to date has concluded.

The research showed that vegan diets resulted in 75% less climate-heating emissions, water pollution and land use than diets in which more than 100g of meat a day was eaten. Vegan diets also cut the destruction of wildlife by 66% and water use by 54%, the study found.

The heavy impact of meat and dairy on the planet is well known, and people in rich nations will have to slash their meat consumption in order to end the climate crisis. But previous studies have used model diets and average values for the impact of each food type.

In contrast, the new study analysed the real diets of 55,000 people in the UK. It also used data from 38,000 farms in 119 countries to account for differences in the impact of particular foods that are produced in different ways and places. This significantly strengthens confidence in the conclusions.

However, it turned out that what was eaten was far more important in terms of environmental impacts than where and how it was produced. Previous research has shown that even the lowest-impact meat – organic pork – is responsible for eight times more climate damage than the highest-impact plant, oilseed.

The researchers said the UK should introduce policies to help people reduce the amount of meat they eat in order to meet the nation’s climate targets. Ministers have repeatedly said they will not tell people what to consume, despite the precedent of, for example, taxes on high-sugar drinks.

Prof Peter Scarborough at Oxford University, who led the research, published in the journal Nature Food, said: “Our dietary choices have a big impact on the planet. Cutting down the amount of meat and dairy in your diet can make a big difference to your dietary footprint.”

The global food system has a huge impact on the planet, emitting a third of the total greenhouse gas emissions driving global heating. It also uses 70% of the world’s freshwater and causes 80% of river and lake pollution. About 75% of the Earth’s land is used by humans, largely for farming, and the destruction of forests is the major cause of the huge losses in biodiversity.

Prof Neil Ward at the University of East Anglia said: “This is a significant set of findings. It scientifically reinforces the point made by the Climate Change Committee and the National Food Strategy over recent years that dietary shifts away from animal-based foods can make a major contribution to reducing the UK’s environmental footprint.”…

What To Consider When Asking Institutions To Shift How They Serve Food

A guest blog from Greener By Default explores and explains the process of getting institutions to consider menu changes and plant-based defaults.

Sarah Thorson & Ilana Braverman , Faunalytics, May 10, 2023

Food choices are extremely personal. They’re informed by our culture, upbringing, education, ethics, and more. For some, food serves as a time capsule keeping familial and cultural history alive, while for others it’s an outward expression of morals and values. Food choices can also be restricted by bodily responses, religious affiliation, and financial realities. And when we work to shift food norms, all of these considerations have to be taken into account to realize widespread change.

For animal advocates working to shift food norms, it can be tempting to ask for the elimination of meat and dairy from menus and diets, since we want to improve the lives of all living beings. But human behavior is complex, and people may respond negatively to a drastic change which they feel is forced upon them. And, with meat consumption still on the rise in the US, psychological research shows that appeals to reduce meat consumption have stronger and longer lasting impacts on eating behaviors than appeals to eliminate meat consumption completely. Serving plant-based meals by default works to accomplish both: preserving freedom of choice, while nudging consumers towards sparing the lives of many animals and lessening food’s overall impact on the environment.

Fostering Inclusivity In Foodservice

Greener by Default (GBD) consults with institutions, including universities, conferences, hospitals, and corporate cafeterias, to serve plant-based meals by default. The default is the option an individual ends up with when they don’t make an active choice. For example, every iPhone user is familiar with the brand’s default ringtone, which most of us don’t bother to change. People tend to stick with defaults partly because it’s one less decision to make, and partly because defaults are often seen as the more socially acceptable option. Because of this tendency, defaults and other behavioral nudges can be used to encourage particular food choices; research shows that implementing plant-based defaults can decrease meat consumption by 53% to 87%, depending on the environment.

With help from GBD, LinkedIn San Francisco was able to switch their menus to serve 65% veg options in the cafeteria and make oat milk the default choice for milk-based drinks in their coffee bar. GBD was also instrumental in helping NYC Health and Hospitals transition their patient meals to serve plant-based meals by default, resulting in over half of eligible patients now choosing plant-based meals. This approach leads to more plant-based options being selected, thus saving many animal lives, while also shifting food paradigms by normalizing plant-based eating. Best of all, because freedom of choice is preserved and there are still meat options available for those who want or feel they need meat at every meal, this approach does not encounter the same type of pushback as fully meatless menus….

Let’s make plant-based foods the default on campus

A ‘default veg’ position on campus food is one way that universities can respond to the climate crisis.

Kathleen Kevany, University Affairs, Oct. 13, 2022

What can universities do to respond to the climate crisis? Our most obvious contributions may come from research and teaching across a range of disciplines: from ecology to the environmental humanities, from engineering to economics and beyond, scholars working in labs and classrooms are trying to mitigate the complex, urgent issues we face.

Yet universities are also much more than engines of research and education. They are societies in themselves, as well as cultural and economic drivers for the broader communities in which they are embedded. The contributions that the students, staff, and faculty who are gathered in universities can offer – and the leadership they can provide – come from many directions.

One critical change that is relatively accessible and affordable and more importantly, more equitable, is to adopt a “default veg” practice. This means changing the current practice of emphasizing meat dishes, to placing the spotlight on plant-based foods on our campuses, while still enabling the full range of dietary choices to be met.

Fulfilling our responsibilities to lead change

We know we need more sustainable food habits. The famous EAT-Lancet report demonstrated that largely plant-based, sustainable diets protect human health and our environments. We are enjoined to “eat local,” to cut food waste, and perhaps above all, to reduce our consumption of meat. The most recent report of the Intergovernmental Panel on Climate Change offered yet more evidence that animal agriculture is among the top contributors to our environmental crisis. Deforestation, soil degradation, habitat and biodiversity loss, animal emissions and waste all compound to make animal agriculture a driving force in global warming, just behind fossil fuel consumption. Even as we seek to limit our use of environmentally destructive fuels to fight climate change, so too must we rebalance our diets.

We also know that universities can be leaders when it comes to sustainability. I teach at Dalhousie University, where signature research clusters are grounded in  the United Nation’s Sustainability Development Goals. Over 30 years ago, Dalhousie hosted a gathering of university leaders who committed to the Halifax Declaration. Echoing an earlier agreement signed in Talloires, France by university leaders from around the world, the agreement made at Dalhousie in 1991 espoused concrete goals and lofty aspirations to direct teaching, research, outreach, and operations toward an equitable and sustainable future. Both declarations affirmed not just the risks to our planet’s integrity but also the urgent responsibilities of universities to lead change….

Changing Behaviour for Net Zero 2050

Marteau, Theresa M., Nick Chater, Emma E. Garnett, “Changing Behaviour for Net Zero 2050,”  British Medical Journal 375 (2021). doi: https://doi.org/10.1136/bmj.n2293

Theresa Marteau and colleagues argue for rapid, radical changes to the infrastructure and pricing systems that currently support unhealthy unsustainable behaviour

“Many major economies, including the US, EU, and UK, have committed to net zero greenhouse gas emissions by 2050 to limit climate change. Immediate action is needed to hit this target and to minimise cumulative emissions. Current commitments are, however, unmatched by action….

The latest International Panel on Climate Change report estimates that if global emissions are halved by 2030 and net zero is reached by 2050, the current rise in temperatures could be halted and possibly reversed. The 26th UN climate change conference (COP26) in November 2021 offers a precious opportunity to get back on track.

Behaviour change by individuals, commercial entities, and policy makers is critical to achieving net zero in all domains. Here we focus on behaviour concerning diet and land travel, given their importance for both achieving net zero and improving population health, but the approaches we outline are also applicable to other behaviours.

Diet and land travel contribute an estimated 26% and 12% of greenhouse gas emissions, respectively. Cutting these emissions would also benefit health by reducing air pollution—now the greatest external threat to human health—increasing physical activity, and healthier diets, thereby tackling major risk factors for non-communicable disease globally.”

“Dietary change is likely to deliver far greater environmental benefits than can be achieved by food producers.”

This paper considers the behaviour of three groups central to achieving net zero by 2050: the public (both as citizens and consumers), policy makers, and private sector leaders.

Key messages:

  • Current government policies globally are insufficient for the rapid decarbonisation needed for net zero by 2050
  • Changing behaviour across populations is key to achieving this as technological innovation will be insufficient
  • Changing behaviour at scale requires changing the environments that drive the behaviour
  • Changes to diet and land travel can be achieved through policies to increase the availability and affordability of healthier and more sustainable options.
  • Policies for net zero need to be driven by evidence and citizens’ values, safeguarded from corporate interference

Meat accounts for nearly 60% of all greenhouse gases from food production, study finds

Production of meat worldwide emits 28 times as much as growing plants, and most crops are raised to feed animals bound for slaughter

Oliver Milman, The GuardianSept. 13, 2021

The global production of food is responsible for a third of all planet-heating gases emitted by human activity, with the use of animals for meat causing twice the pollution of producing plant-based foods, a major new study has found.

The entire system of food production, such as the use of farming machinery, spraying of fertilizer and transportation of products, causes 17.3bn metric tonnes of greenhouse gases a year, according to the research. This enormous release of gases that fuel the climate crisis is more than double the entire emissions of the US and represents 35% of all global emissions, researchers said.

“The emissions are at the higher end of what we expected, it was a little bit of a surprise,” said Atul Jain, a climate scientist at the University of Illinois and co-author of the paper, published in Nature Food. “This study shows the entire cycle of the food production system, and policymakers may want to use the results to think about how to control greenhouse gas emissions.”

The raising and culling of animals for food is far worse for the climate than growing and processing fruits and vegetables for people to eat, the research found, confirming previous findings on the outsized impact that meat production, particularly beef, has on the environment.

The use of cows, pigs and other animals for food, as well as livestock feed, is responsible for 57% of all food production emissions, the research found, with 29% coming from the cultivation of plant-based foods. The rest comes from other uses of land, such as for cotton or rubber. Beef alone accounts for a quarter of emissions produced by raising and growing food….

The paper’s calculations of the climate impact of meat is higher than previous estimates – the UN’s Food and Agricultural Organization has said about 14% of all emissions come from meat and diary production. The climate crisis is also itself a cause of hunger, with a recent study finding that a third of global food production will be at risk by the end of the century if greenhouse gas emissions continue to rise at their current rate.

Scientists have consistently stressed that if dangerous global heating is to be avoided, a major rethink of eating habits and farming practices is required. Meat production has now expanded to the point that there are now approximately three chickens for every human on the planet.

Lewis Ziska, a plant physiologist at Columbia University who was not involved in the research said the paper is a “damn good study” that should be given “due attention” at the upcoming UN climate talks in Scotland.

“A fundamental unknown in global agriculture is its impact on greenhouse gas emissions,” Ziska said. “While previous estimates have been made, this effort represents a gold standard that will serve as an essential reference in the years to come.”

Plant-Based Food Sales to Increase Fivefold By 2030, BI Says

Elizabeth Elkin, Bloomberg.com, Aug. 11, 2021

The global market for plant-based foods could see fivefold growth by 2030 helped by rising demand for sustainable products, according to a Bloomberg Intelligence report.

Sales of plant-based dairy and meat alternatives reached $29.4 billion in 2020, and could increase to $162 billion by 2030, comprising 7.7% of the global protein market.

Demand is increasing as companies like Beyond Meat Inc., Impossible Foods Inc. and Oatly Inc. bring alternative protein products to more restaurants and grocery stores. Legacy food companies like Tyson Foods Inc., Kellogg Co. and Nestle SA are also competing in the space with their own plant-based burgers and milks. They’re using their scale to drive distribution and working with retailers on promotions and marketing.

Meat and dairy substitutes are marketed as healthier and more sustainable than the products from animals that they aim to replace. They’re getting popular just as consumers become more conscious of the environmental footprint of food, and aim for healthier eating. Asia will also be a significant driver of plant-based protein sales because it’s vulnerable to limited food supplies, the report said.

Berlin’s university canteens go almost meat-free as students prioritise climate

Philip Oltermann,The Guardian, August 31, 2021

Students at universities in Berlin will from this winter swap currywurst and schnitzel for seeds and pulses, as campus canteens in the German capital make heavy cuts to their meat and fish options.

The 34 canteens and cafes catering to Berlin’s sizeable student population at four different universities will offer from October a menu that is 68% vegan, 28% vegetarian, and 2% fish-based, with a single meat option offered four days a week.

Students will be able to nourish themselves over the winter months with meals including buckwheat and spelt bowls topped with grilled sweet potatoes, marinated beetroot and sesame seeds, or pasta bakes with tomato and cheese.

“We developed a new nutritional concept mainly because students have repeatedly approached us with the request for a more climate-friendly offer at their canteens,” said Daniela Kummle of Studierendenwerk, the organisation providing economic, social, health and cultural support to students enrolled at Berlin’s higher education institutions.
