Our overall environmental performance is measured by our carbon footprint, and we include Scope 1, Scope 2 and significant Scope 3 GHG emissions within this profile. Our goal is to reduce our relative carbon footprint by 30% by 2020 (against a 2010 baseline) and we continue to perform strongly against this target.
We have improved our refrigeration systems to use ammonia rather than F-Gas and this has reduced our absolute carbon footprint by over 10,000 tonnes CO₂ as they are significantly more economical to run.
We are also investing in Combined Heat & Power (CHP) in various forms using both biomass and gas-fired systems.
The majority of our GHG emissions come from electricity and gas, which are continuously monitored and we are constantly looking for ways to reduce these. Our livestock also account for a significant level of GHG emissions and we are working to quantify those impacts where possible.
We have undertaken a carbon footprint assessment of our Wayland Farms sites to estimate the carbon footprint of our pigs at each stage of their development. We achieved a B-rating for carbon performance per finished pig (3,14 kg CO₂/Kg LW), above the average C-rating (4,68 kg CO₂/Kg LW) for our industry. We are now planning to scale up these carbon assessments across all of our farms.
