Enter your typical weekly meat intake in ounces. You get an annual footprint in CO₂, water, and land use, plus how you compare and where to reduce.
Rough amounts per week. Use averages if it varies.

We use impact factors per ounce (about 28 g) of meat: CO₂ equivalent (kg), water (liters), and land (m²). Beef and lamb have the highest factors; chicken and fish are lower. Weekly totals are multiplied by 52 for annual impact. Comparison is to a rough US average of about 124 lbs of meat per person per year. These are estimates from published lifecycle data, not lab measurements. Regional and production methods vary.
Reduction scenarios (e.g. Meatless Monday, cutting beef by half) show how much CO₂ and water you could save with small changes.
Factors assume typical production (e.g. grain-fed beef, conventional poultry). Grass-fed, local, or different farming systems change the numbers. We do not model transport or packaging. Use this tool for ballpark comparison and habit awareness, not for exact carbon accounting.
Reduce red meat first (beef, lamb) for the biggest drop. Swap some meals for poultry, fish, or plant-based options. Meatless Monday alone cuts about one-seventh of your meat footprint. Portion size and quality over quantity also help.
