Oxford Study: Diet and Greenhouse Gas Emissions

This project analyzes the environmental impact of different diet groups (vegans, vegetarians, fish-eaters, and meat-eaters) in the United Kingdom, based on data from 2022. The study explores how dietary choices influence greenhouse gas (GHG) emissions.

Overview

• Tool Used: Python
• Dataset: The Environmental Impact of Vegans, Vegetarians, Fish-eaters, and Meat eaters in the UK (2022)
• Country: United Kingdom

Visualizations

• Treemap: Visualizes the hierarchical relationship of diet group → sex → age group, with rectangle size and color mapped to mean GHG emissions.
• Bar Chart: Displays the percentage of participants in each diet group across different age groups.

Key Findings

• Meat eaters produce the highest greenhouse gas emissions.
• Vegans have the lowest greenhouse gas emissions.
• Younger individuals have a higher proportion of vegans and vegetarians compared to older individuals.
• Meat eaters are the majority in every age group.

Data Preparation

• Related diet groups (meat, meat50, meat100) were merged into a single "Meat Eater" group.
• Data was grouped by diet group, sex, and age group to calculate mean GHG emissions.
• Another grouping was performed to determine the percentage of each diet group within age groups.
• Hierarchical structures were prepared for the treemap visualization.
