The challenge

Our client had bold sustainability goals for 2030 and 2050 and needed enterprise-wide transformation, including requiring the business to decarbonise its stores and fleets, developing circular retail solutions and shifting consumer behaviours towards plant-based proteins.

The sustainability team had set targets, defined some initiatives and started to make progress on quick wins – but they needed to create a coherent, robust transition plan to ensure the business was set up to deliver on their goals long-term. Gate One partnered with their sustainability leaders to create a Transition Plan using the gold standard Taskforce framework, which could be used internally and published to stakeholders externally.


Executive alignment: Interviewed Executive-level leaders to align on sustainability ambitions and transition plan challenges.

Business engagement: Engaged with stakeholders across the business via “Accelerator” workshops to assess business impact of the ESG strategy and potential delivery blockers.

Gap analysis: Assessed the gaps between existing strategies and requirements for the Transition Plan Taskforce framework.

Transformation assessment: Assessed effectiveness of governance to manage delivery and developed future state operating model for ESG delivery.

Disclosures: Developed an external disclosure on the transition plan, targets and metrics for inclusion in the annual report.

Summary output: Created an internal strategy summary document, aligning the client’s purpose, ESG strategies and external narrative.
