Oxford Uehiro Centre for Practical Ethics square purple and white logo

To align our food practices with our commitments to rational reflection on the most salient ethical issues of our time, the Oxford Uehiro Centre for Practical Ethics is adopting DefaultVeg for all meetings and events that we host. This commitment sets the default and easiest option to plant-based foods, in recognition of scientific research on the environmental benefits of a plant-based diet and philosophical research by Singer and others on our relationship to animals.

Dr Katrien Devolder (OUC Senior Research Fellow and DefaultVeg Ambassador) says:

 “The Uehiro Centre is committed to examining, understanding, and addressing 21st Century ethical challenges, including the environmental, health, and animal welfare costs of industrial animal agriculture. We are therefore adopting DefaultVeg for all meetings and events hosted by the Centre. This commitment allows us to shift our purchasing power towards plant-based foods, while still preserving freedom of choice for every meal."

What is DefaultVeg?

DefaultVeg is an international partnership between three organisations; The UK Food Plan, CreatureKind and The Better Food Foundation. Each partner shares the goal to change the way organisations think about and source their food.

DefaultVeg is run in the UK by the UK Food Plan and led in United States by The Better Food Foundation. 

It is a simple and inclusive way to offer healthier and more sustainable meals.  Menus feature plant-based meals as the default option, while giving diners the choice to add or opt into meat and/or dairy options upon request. Research shows that by simply changing the default, consumers are much more likely to choose a plant-based meal, even when meat and dairy options are available.1

Our Commitment to DefaultVeg

To achieve our aim, where Centre funds are used for catering we will follow these best practices: 

Office refreshments
For teas and coffees, a selection of plant-based milks are provided by default.  OUC Members working at the Centre are offered the opportunity to opt-in to dairy.

Catering for meetings and workshops
Hot drinks: We will provide two plant-based milk options, and one dairy option. 
Food: We have engaged with local suppliers who can provide a predominantly vegan menu. We will alert our participants to our DefaultVeg commitment whilst offering them the opportunity to opt-in to dairy and meat/dairy products.

College dinners
Where possible we will arrange for two/three options per course: one/two vegan and one non-vegan and will let participants know to opt-in if they prefer meat/dairy. If it is not possible to offer a choice, we will preselect a vegan only menu.

Where possible we will work with our local restaurants to devise party menus that offer two vegan and one non-vegan option, as above.

Summary by "Vegetarian and vegan diets are best for the environment and human health, according to research published online in the Proceedings of the National Academy of Sciences of the United States of America. Researchers assessed several regional models that incorporated environmental, economic and health impacts associated with a dietary change in the future. Diets compared included proportional reduction in animal products, reduced or meat-free diets, and diets based on current health standards. A shift to a plant-based diet projected reductions in global mortality and greenhouse gases caused by food production by 10 percent and 70 percent, respectively, compared with a control scenario set in 2050. A global dietary shift would save an estimated 79 million human lives and avoid 5.1 million deaths per year. Estimates for a completely vegan diet project closer to 129 million lives saved and 8.1 million deaths avoided. These projections also saw trillions of dollars saved in health care costs by 2050."

This paper explores the role of the global food system as the principal driver of accelerating biodiversity loss. It explains how food production is degrading or destroying natural habitats and contributing to species extinction. The paper outlines the challenges and trade-offs involved in redesigning food systems to restore biodiversity and/or prevent further biodiversity loss, and presents recommendations for action.

EAT-Lancet Commission Summary Report (2019).

"Transformation to healthy diets by 2050 will require substantial dietary shifts. Global consumption of fruits, vegetables, nuts and legumes will have to double, and consumption of foods such as red meat and sugar will have to be reduced by more than 50%. A diet rich in plant-based foods and with fewer animal source foods confers both improved health and environmental benefits."

IPBES Workshop on Biodiversity and Pandemics. IPBES 2020.

Pandemics represent an existential threat to the health and welfare of people across our planet. The scientific evidence reviewed in this report demonstrates that pandemics are becoming more frequent, driven by a continued rise in the underlying emerging disease events that spark them. Without preventative strategies, pandemics will emerge more often, spread more rapidly, kill more people, and affect the global economy with more devastating impact than ever before. Current pandemic strategies rely on responding to diseases after their emergence with public health measures and technological solutions, in particular the rapid design and distribution of new vaccines and therapeutics. However, COVID-19 demonstrates that this is a slow and uncertain path, and as the global population waits for vaccines to become available, the human costs are mounting, in lives lost, sickness endured, economic collapse, and lost livelihoods.

"The leading scientists behind the 2018 IPCC report warned that we have a mere 12 years to keep global temperatures under 1.5 degrees Celsius, beyond which only half a degree more will dramatically increase chances of flooding, drought, and extreme heat."

This study finds that poor diet is linked to one in five deaths worldwide. “Among all forms of malnutrition, poor dietary habits — particularly low intake of healthy foods — is the leading risk factor for mortality.”
