Specific objection to waste. Construction waste can normally be 80-90% diverted from landfill. There is also confusion in recycling vs landfill in the three targets.

Suggest
Bronze - Implement a SWMP and record waste removed from site
Silver - Greater than 80% of waste diverted from landfill
Gold - PAS 402 contractor used to manage waste, demonstrating 95% diversion from landfill or greater

Passive Design Principles and WLC should be made more stretching and more specific / clear about what is targeted. For example LETI standard or equivalent is not entirely clear. Also the WLC targets could have the gold standard as <300 to meet Leti 2030 Design Target
