Decision Tree Workshops - Green-Software-Foundation/toss GitHub Wiki


We are running a series of virtual workshops to shape the future of our Transforming Organisational Software Sustainability (TOSS) project.

We want to

Build out the decision tree frameworks for all four pillars - Strategy, Implementation, Operational, Compliance and Regulations.

The TOSS project team is actively developing a framework that encapsulates an underlying methodology and decision trees for organisations to 1) Embed 2) Transform and 3) Use software emissions data to help achieve their Net Zero targets. The framework provides companies with an approach to build a future-proof foundation for continuous improvement and change management regarding the sustainable development and use of their software operations.


The workshops will run on:

  • Monday 15th July - TOSS Orientation
  • Monday 22nd July - Strategy pillar
  • Monday 29th July - Implementation pillar
  • Monday 5th August - Operational pillar
  • Monday 12th August - Compliance and Regulations pillar
  • Monday 19th August - Wrap-up

Each workshop will run between 14:00 - 15:00 UTC.
