Snacking on Emissions
Eating and drinking are absolutely central part of live performances - whether that be in keeping artists and crew going through intensive work schedules, or for audiences as part of the live event experience. Large quantities of food and drink are consumed, for which considerable resources are required in the production stages; and when we don't finish our food and drink, these resources effectively go in the bin, so there is also the issue of waste. Both food production and disposal leads to the emission of GHGs, alongside other environmental impacts.
There are plenty of good reasons to engage with reducing food's GHG impact including economic, environmental and marketing drivers. Through awareness and targeted action by those responsible for food provision in the live performance sector, GHG emissions can be reduced. This sheet is aimed at those who procure food, lease catering tenders and cook/ prepare food in the live performance sector. A brief introduction to the GHG emissions of food is provided here, alongside the policy context and some guidance.
Food - a Climate Change Contributor
Food is thought to be responsible for 20-30% of our national GHG emissions (1) (Audsley, Brander et al. 2009). Similarly, at the EU level food has also been calculated to contribute 30% of total emissions. Climate changing gases arise at all stages of food production, preparation and disposal. See Figure 19 for a diagram of two supply chains for foods commonly sold at live performance venues - beer and beef burgers. These also happen to be relatively GHG intensive food stuffs.
Farming in particular, through the production and use of fertilisers, the creation of feed for livestock, the emission of methane (CH4) burps from ruminant (cows, sheep) digestion and nitrous oxide (N2O) from soil (2), emits comparatively more GHGs than other stages of the food chain. That is not to say however that other stages of production - whether that be transporting food, processing, manufacturing, packaging or cooling it - do not also warrant looking into. In fact, in many cases it can be easier to reduce emissions from the non-farming stages as methane and nitrous oxides in particular are harder to measure and manage.

The Impact of Climate Change on Food
Climate change will also impact food in the longer run. As the climate changes the conditions for growing food will alter. While it is anticipated that this might be beneficial for northern latitudes in the shorter term to 2050, it is likely to have a negative impact for less developed countries in mid to low latitudes. Assuming we continue to emit greenhouse gases globally at the current rate, towards the end of this century climate change is expected to have an increasingly negative effect on agriculture across all countries (Parry et al 2007). Extreme weather events will also affect distribution and other production infrastructure.
Government Policy on Food and Climate Change
The government has signed up to 80% reductions in GHG emissions by 2050 - a large target that will affect each stage of the food chain. To date the food industry has not been specifically targeted by regulations to reduce emissions although a number of policies, such as the climate levy (a tax on energy) and the EU Emissions Trading Scheme do affect some parts of the supply chain. The most specific development for encouraging the food and drink industry to assess and improve environmental performance has been the Food Industry Sustainability Strategy, an industry lead initiative, and PAS 2050, a product carbon footprinting and labelling scheme developed by the Carbon Trust.
Voluntary Initiatives Underway
Adnams - A brewery that has developed an environmental and social policy that shapes their business development. They have taken a number of environmental initiatives such as producing a carbon neutral beer and a distribution centre with grass roof, rainwater collection, renewable energy sources, and environmentally benign materials and design.
To learn more check out this video:
E-CO2 - The E-CO2 Project seeks to carbon footprint farmers and growers, and gives advice on renewable energy generation on farms. They have been working with McDonalds.
Large Retailers - Retailers are taking increasing interest in the greenhouse gas emissions in their supply chains, including carbon labelling. For example Tesco is working with dairy farmers to examine emissions in the supply chain and opportunities for improvements.
Guidance to the Live Performance Sector
There are a number of strategies that will reduce the emissions created by food and drink consumption. Table 1 outlines 5 broad approaches and gives examples of the types of actions that can be taken under each approach.
Suggestions for Venues
- Develop a sustainable procurement policy for food and drinks.
- Learn about the environmental impacts of food and drink sold at the venue.
- Assess the energy used for food and drink provision and identify opportunities for energy savings.
- Work with contracted food and drink concessions to offer consumerables with low environmental impacts.
- Communicate efforts to reduce the environmental impact of food and drinks to audiences.
Suggestions for Incoming Productions
- Hire caterers with environmental policy and credentials.
- Ask venues about their food and drinks procurement policy and about the actions they are taking to reduce its environmental impacts. This could be part of a green rider.
