Defra and STAR

  • STAR (Sustainable Technology Advice and Reporting) requires departments to report quarterly across IT emissions categories
  • This will allow in year review of emission reduction for all three emission scopes across DWP IT infrastructure / operations
  • Proposed Metric : 7/8% reduction year on year (Scope 1 -3)
  • Supports
    • Annual STAR reporting
    • Quarterly Cabinet Office Reporting for Sustainability
    • DDaT Mission 4 reporting
    • Greening Government 2021 – 2025 commitment

“Co-Doc: We don’t have access to the numbers of developers/engineers needed to maintain and translate that code into cloud friendly technology quickly and efficiently. We are therefore exploring how Gen AI can do this for us using legacy code to generate up-to-date documentation and creating modern code from documentation.”�DWP Digital Group Hub
