The development of the score would stand up to scrutiny of the members.  This is the same format of survey that organisations use to evaluate the effectiveness of hospitals, schools, police forces and others.  Questions are rposed which assess the effectiveness of the work or organisation.  Quantitative answers are provided, such as the following questions, and national rankings are provided.   Over time the index criteria will evolves as some areas gain in importance.  The criteria will include a over 40 questions.  Examples of the scope of the questions asked include:  

Governance

• When was your sustainability strategy last reviewed?
• When was the action plan last reviewed?
• Does the action plan included mitigation and adaptation to climate change?
• Is a board member overseeing the sustainability action plan? 

Existing Buildings

• Is any effort made to incorporate sustainable materials in the refurbishment of homes?
• Is any effort made to incorporate water efficient technologies in refurbishment?
• Are residents receiving advice on flooding preparedness?
• Are residents receiving advice on more efficient appliances?

New Build

• Is the average SAP rating (this is a measure of the energy efficiency of buildings) above the national average?
• Are residents informed of how to use their homes in an energy efficient way?
• Has adaptation to climate change been considered in the design of homes?

In the intervening years a specific topic will be chosen, such as water efficiency or resident involvement.  A quantification of performance (this could be a score out of 100 or a rating much like the energy efficiency badge) would also be developed on this subject area.

For members, such as housing associations, membership provides the opportunity for assessment of progress on sustainability against peers, and bespoke interaction with housing experts on how to improve.
