Litter sources and hotspots are poorly measured at an actionable granularity
#00081
Decision-makers rarely have street-level data on where litter concentrates, what it is, and which brands it come from. Without comparable, location-specific evidence, interventions can't be targeted, producers can't be held accountable, and nothing can be proven to work.

Description
Why this is its own facet
Most litter response happens without good data. Authorities seldom know, at street or beach granularity, where litter concentrates, what it is composed of, which products and brands recur, or whether a given intervention actually reduced it. Traditional litter surveys are slow, manual, and hard to scale, so the evidence base lags far behind the problem.
Consequences of the gap
Without comparable, location-specific measurement: cleanups and infrastructure get placed by guesswork rather than at true hotspots; producers cannot be held accountable for the specific items they put into the waste stream; and programmes cannot demonstrate impact, undermining the case for funding what works.
Why it is a distinct facet
This is a measurement and information problem that sits beneath every other litter intervention — the precondition for targeting, accountability, and evaluation — rather than a litter stream in itself.
