Evidence & Context

Therefore, the benchmark for Litter Cover (%) representing the best available condition in a high-functioning, sustainably managed urban ecosystem is 100%.

Metric Definition:

Litter Cover (%) on managed pervious surfaces in urban and developed land uses.

Benchmark Definition:

The best available condition benchmark for litter cover in urban tropical rainforest biome.

Justification:

This benchmark is based on Brisbane City Council's standard drawings for stormwater treatment assets, representing a high-functioning, sustainable, and replicable standard for urban green infrastructure.
