Food for Synagogues
This section covers the food and drink that you serve in your synagogue. It is broken into two parts: Kiddush and Yom Tovim Meals
The emissions factors for Kiddush meals are based on data supplied by Eco Synagogue for a typical Kiddush meal served to 200 people after a Shabbat service.Item | Emissions per item (kgCO₂) | Emissions per person (kgCO₂) |
3.6 kg (8 lbs) of fishballs | 19.75 | 0.099 |

The emissions factors for the different foods are taken from Agribalyse, the factors from Agribalyse are kgCO₂ per kg of product. Liquid quantities have been converted from litres to kg.
Other Meals
As well as Kiddush and Yom Tovim meals, other types of meals can be added to the synagogues carbon footprint. The emissions estimate given for meals is from “farm to fork” and includes packaging and transport to the supermarket.The data we use for estimating the carbon footprint of your synagogues's other food comes from a study conducted by Dr Peter Scarborough of Oxford University called “Dietary greenhouse gas emissions of meat-eaters, fish-eaters, vegetarians and vegans in the UK” (available here).
The study was based on data from the UK and each factor covers a day's food – 2,000 kcal diet. Churches don't tend to serve three meals a day so for the purposes of estimating emissions for churches we have taken a proportion of Dr Scarborough's figure in line with NHS guidance about how we should split our calories across meals in a day (excluding drinks). The NHS suggests a 400-600-600 split between breakfast, lunch and dinner. This gives a “weighting” for a single meal – lunch or dinner – of 0.375, which we have used for the six meal factors.
The emissions factors we have used are:
Meal type | Factor (kgCO₂/meal) | Notes |
High meat-eater | 2.696 | More than 100g per day |
Medium meat-eater | 2.111 | Between 50g and 100g per day |
Low meat-eater | 1.751 | Less than 50g per day |
Fish | 1.466 | |
Vegetarian | 1.429 | |
Vegan | 1.084 |
Some average weights for meat products:
- Quarter pounder burger – 227g
- Rump steak – 200g
- Lamb chop – 150g
- Chicken drumstick – 85g
Even within the UK there are many factors that can affect your food carbon footprint. For example:
- Food that is bought locally will typically (but not always) have a smaller footprint than food that comes from abroad.
- Produce that is “in season” will have a smaller footprint than “out of season” produce because it will usually have been produced in the country where it will be consumed – so it will travel less.
- Different supermarkets have different supply chains and those supply chains will have different carbon footprints depending on how efficient they are and where the supermarket sources goods.
- How far you travel to buy food – your carbon footprint from getting your food home isn't included here, but should be entered in the Travel tab.
