Emissions from food items can be significantly reduced by favouring a plant-based diet and switching from high-emitting food to low-carbon options.

Based on the carbon footprint, organisations should identify food items with the highest relative and absolute emissions and focus their efforts on those. The sourcing strategy for food should be reviewed in close collaboration with nutritionists and staff on the ground in order to identify opportunities for switching to low-carbon food options, such as replacing meat with plant-based proteins, reducing rice sourcing and switching to alternatives like pulses.

The production of food is estimated to produce between 21 and 37% of overall anthropogenic emissions. (1) For aid organisations, food is often mostly sourced for beneficiaries. This is also typically the area with the highest impact on the footprint – due to the large quantities of food sourced. Other examples of food sourcing are the canteen, catering at events, or business lunches. Whilst the impact of food choices in these areas on the overall footprint might be comparatively little, it can make a strong contribution to changing eating habits.

Key facts

20 times more

The production of beef, sheep or goat meat emits 20 times more emissions per gram of protein than legumes and requires 20 times more land (3)

Lower impact per tonne

Pulses, maize and wheat have a much lower greenhouse gas impact per tonne of protein than rice (4)

1.5%

Methane from rice contributes 1.5 % of global greenhouse gas emissions and 10% all agricultural emissions (5)

Key actions

  • #1 Prioritise

    Identify food items with the largest absolute and relative impact on the carbon footprint.

  • #2 Identify potential alternatives

    Use publicly available data (see below) to identify potential low-carbon alternatives.

  • #3 Increase sourcing of plant-based options

    Reduce animal-based products when possible (especially ruminant meat: beef, sheep, and goat) and increase plant-based options.

  • #4 Diversify rice sourcing

    At least partly replace rice with less carbon-intensive alternatives, such as pulses, maize, wheat, ideally sourced locally or regionally.

  • #5 Engage with key internal stakeholders

    Involve nutritionists and staff in close contact with beneficiaries to ensure a nutritious and balanced diet and culturally acceptable choices when selecting alternative options.

  • #6 Streamline the procurement process

    Integrate carbon data on key food items into the food procurement decision-making process.

  • #7 Increase plant-based options in the canteen

    Integrate criteria to increase the percentage of plant-based options in contracts with the service provider for the canteen and caterers.

To consider

  • Potential co-benefits

    • Positive health impact through reduced meat consumption and diversification of diets
  • Success conditions

    • Internal awareness-raising on health, environmental and climate impacts of food sourcing
  • Prerequisites & specificities

    • Availability of alternatives in the required quantity
  • Potential risks

    • Potential impacts on the supply of nutrients to beneficiaries need to be considered in close collaboration with nutritionists

Success stories

EU Green Public Procurement Criteria

The EU green public procurement criteria for food, catering services and vending machines include criteria to increase the consumption of pulses, vegetables, fruits, wholegrains and nuts, for example: X vegetarian or plant-based dishes to be offered daily or ‘dish of the day’ to be a vegetarian or plant-based dish. The tenderer must provide the menu planning with the alternatives. (6)

City of Helsinki: Reducing the use of dairy and meat products

The use of dairy and meat products in the city of Helsinki food services will be reduced by 50% by 2025. (7)

Unilever: Products that deliver positive nutrition

Unilever set a goal to double the number of products sold that deliver positive nutrition (i.e. containing plant-based meat and dairy alternatives) by 2025 (as % of servings sold). (8)

UN ESCAP: Sustainable catering at events

UN ESCAP (The Economic and Social Commission for Asia and the Pacific) gives preference to fish and vegetarian proteins over meat-based ones for events. (9)

Although we explore a range of scenarios, we identify reductions in consumption of ruminant meat (beef, sheep, and goat) as the most promising strategy for reducing land requirements and GHG emissions—while also achieving health benefits. (…) by counting the full consequences of diets for land use, we find that diets in general—and consumption of ruminant meat in particular—are even more significant for GHG mitigation than commonly understood WRI, Creating a Sustainable Food Future, 2019
