Eco Footprint Visualizer

Show the impact of partial and full dietary shifts Most tools only show static “all or nothing” comparisons. We want people to see what happens if they move 25%, 50%, or 75% toward plant-based diets - making the science both personal and actionable.

Scale individual choices to collective change Let users multiply results across groups - from 1 person to millions. This helps organizations, schools, sports teams, and even countries explore “what if we all shifted together?” scenarios.

Highlight the full spectrum of impacts Deliver clear outputs on greenhouse gases, land use, water use, eutrophication, and acidification, while adding often-missing layers: biodiversity outcomes, animal lives spared, and broader opportunities to rewild and draw down carbon.

Make abstract data relatable through visualization Use dynamic, scenario-based visuals that translate numbers into familiar comparisons: football fields for land, swimming pools for water, cars off the road for emissions, species icons for biodiversity.

Enable transparency and credibility Ground the calculator in Poore & Nemecek’s dataset, complemented by Clark et al., 2022 and work from Tim Searchinger, FAO, WWF, IPBES, and others. Provide clear references so users know the source and reliability of each metric.

Create a tool for individuals and institutions For individuals, the calculator reveals the real power of everyday choices - even if they don’t go 100% plant-based. For organizations, it offers a data-backed alternative to questionable carbon offsets, showing how dietary shifts can meet sustainability goals.

Bridge science and outreach at scale

The calculator will serve as a direct, interactive way for millions to engage with the data and see their potential impact in real time.

Engagement & Reach: Total users, sessions, and time spent exploring scenarios.

Scale of Use: Number of dietary shifts modeled (individual, group, organizational).

Behavioral Impact: % of users reporting intent or action to reduce animal-based foods.

Scientific Credibility: Transparent sourcing (Poore & Nemecek, FAO, WWF, IPBES) and endorsements from this.

Distribution Impact: Downloads, shares, and use by schools, NGOs, and companies.

The visualisations will power the Food Impact Calculator, turning complex science into simple, relatable insights. They will be used by the general public, schools, teams, and community groups to model “what if” scenarios, and by organizations as a credible alternative to offsets in their sustainability plans.

Advocacy groups will use them to highlight biodiversity and animal welfare co-benefits, while researchers and policymakers can rely on them as transparent, data-backed tools. The aim is to inform personal choices, collective actions, and institutional strategies by showing the real-world impact of shifting diets.
