Plant-based pledges & public challenges (Veganuary, Meat Free Monday)
Why this action matters
Evidence-groundedThe current food system drives poor dietary choices and unsustainable environmental impacts, as evidenced by the high environmental costs of animal-based products, which exceed those of plant-based alternatives in terms of greenhouse gas emissions, land use, and water consumption. Transitioning to more sustainable consumption patterns, such as increasing plant-based diets and reducing reliance on high-impact animal products, is essential to address these challenges and support a resilient food system.

Consequences of this action
Evidence-groundedThe action itself
The institution publicly commits to time-limited collective challenges that normalise plant-based eating and build community participation through initiatives such as Veganuary and Meat Free Monday.
UK implications
This action generates measurable short-term dietary shifts, with evidence showing that participants in Veganuary demonstrate sustained dietary change beyond the challenge month, contributing to reduced greenhouse gas emissions and lower land use associated with meat consumption in the UK.
Global implications
UK leadership in these movements amplifies global efforts, as similar initiatives operate in over 50 countries and collectively reach tens of millions of participants annually, promoting shifts toward plant-based diets that can reduce global biodiversity loss and improve food security.

Climate Resilience
The global food system is the single largest activity driving the climate crisis, primarily due to its significant contribution to greenhouse gas emissions and biodiversity loss [Rockström et al., 2023] Animal agriculture is a leading driver of biodiversity loss, terrestrial ecosystem degradation, and excessive freshwater use [Rockström et al., 2023] A shift to plant-based diets can reduce land use by up to 75 per cent, freeing up space for rewilding and restoring ecosystems [Rockström et al., 2023] Public pledges and challenges, such as Veganuary and Meat Free Monday, can drive behavioral change by increasing awareness and promoting plant-based consumption [Rockström et al., 2023] Rewilding and reforestation, supported by shifting away from meat and dairy, can restore vital ecosystem functions and sequester carbon [Rockström et al., 2023]
Equity & Access
The global food system is the single largest activity driving the climate crisis, primarily due to its significant contribution to greenhouse gas emissions and biodiversity loss [Rockström et al., 2023] Animal agriculture is a leading driver of biodiversity loss, terrestrial ecosystem degradation, and excessive freshwater use [Rockström et al., 2023] The current global diet uses 4.13 billion ha of land, with 43 per cent of cropland used to raise farmed animals rather than feed humans directly [Rockström et al., 2023] Public pledges and challenges, such as Veganuary and Meat Free Monday, can help shift consumption patterns by promoting plant-based diets and reducing reliance on animal agriculture [Rockström et al., 2023] Addressing equity and access in food transitions is essential to ensure that marginalized communities, including Indigenous peoples and climate migrants, benefit from sustainable food systems [Rockström et al., 2023]
