According to a special report by the IPCC (Intergovernmental Panel on Climate Change), the global temperature needs to be below 1.5 °C to avoid a climate disaster that could worsen hunger, conflict, and drought worldwide. This would require CO₂ emissions to decline by about 45% from 2010 levels by 2030 and reach net zero around 2050.

A technical report published by the IGES (Institute for Global Environmental Strategies) showed that in order to achieve the 1.5 °C target, the global average annual carbon footprint per person needs to be 2.5 tonnes of CO₂ equivalent in 2030, 1.4 by 2040, and 0.7 by 2050.

Food accounts for 10-30% of a household's carbon footprint as stated by the Center for Sustainable Systems - University of Michigan. A study published in Nature Food found that 34% of global greenhouse gas emissions come from food.

We decided to assume on average that 30% of an individual's carbon footprint is food based on the percentage of food emissions that accounts for a household's carbon footprint and the percentage of food emissions that accounts for the global greenhouse gas emissions.

Keeping in mind what the global average annual carbon footprint per person needs to be to reach the 1.5 °C target, the global average annual food carbon footprint per person needs to be 0.75 tonnes of CO₂ equivalent in 2030, 0.42 by 2040, and 0.21 by 2050.

With only a few years left until 2030, we are focusing on trying to help our users maintain a food carbon footprint of 0.75 tonnes per year.

This is how we evaluate the total GHG emissions to determine what color they should be:

• Green:
• Current Today emissions are below 1.85 kg of CO₂ equivalent
• Current This Week emissions are below 12.95 kg of CO₂ equivalent
• Current This Month emissions are below 55.50 kg of CO₂ equivalent
• Current This Year emissions are below 675 kg of CO₂ equivalent

• Yellow:
• Current Today emissions are above 1.85, but below 2.05 kg of CO₂ equivalent
• Current This Week emissions are above 12.95, but below 14.35 kg of CO₂ equivalent
• Current This Month emissions are above 55.50, but below 61.50 kg of CO₂ equivalent
• Current This Year emissions are above 675, but below 750 kg of CO₂ equivalent

• Red:
• Current Today emissions are above 2.05 kg of CO₂ equivalent
• Current This Week emissions are above 14.35 kg of CO₂ equivalent
• Current This Month emissions are above 61.50 kg of CO₂ equivalent
• Current This Year emissions are above 750 kg of CO₂ equivalent

To summarize, if the GHG emissions are green, you are well on track to keeping your food carbon footprint below 0.75 tonnes per year. Yellow can be seen as a warning sign. You are still on track to keeping your food carbon footprint below 0.75 tonnes per year, but you are getting close to going over our yearly target for food emissions. Red is to show you that your food carbon footprint will be (or already is) above 0.75 tonnes per year if you continue to consume foods where the GHG emissions are colored red.

As of right now, you can get up to 20 recipes for every search request made. By default, your list of recipes is sorted by their calculated GHG emissions in ascending order (least to greatest).

Our image AI is able to process various formats. We do suggest images where each ingredient is on a separate line and in the following format:

The order of elements for each line does not matter. For example, your lines can be in the following format:

• Chicken 100 g
• 1 pound beef
• 2 Rice Kilograms
