Tesco: Science-based target case study

Tesco has committed to reducing its scope 1 and 2 emissions by 60% by 2025 and scope 3 emissions by 17% by 2030, both using a 2015 base-year. To achieve these goals, the company is implementing a costed renewable electricity roadmap and investing in energy and refrigeration efficiency, having already spent over £700 million since 2006. Tesco aims for 100% renewable electricity by 2030 and a net-zero carbon status by 2050, while managing specific challenges related to agricultural emissions, which constitute approximately 70% of its supply chain emissions.

• Tesco's approved science-based targets include a 60% reduction in direct (scope 1) and indirect (scope 2) greenhouse gas emissions by 2025 and a 17% reduction in scope 3 emissions by 2030, both relative to a 2015 base-year.
• The company aims to source 100% of its electricity from renewable sources by 2030, with a requirement that over 50% comes from on-site generation and Power Purchase Agreements (PPAs).
• Since 2006, Tesco has invested more than £700 million in refrigeration and energy efficiency, resulting in a 41% reduction in emissions per square foot for its distribution centres and stores.
• Agricultural emissions are a significant challenge, representing approximately 70% of Tesco's supply chain emissions, leading the company to set a separate reduction target for agriculture compared to other scope 3 sources.
• Tesco has already achieved 100% renewable electricity usage in the Republic of Ireland and the UK, and invested £8 million in onsite generation in Asia during 2016.
