摘要: A conceptually complete taxonomy is proposed at three levels of the impact pathway: Elementary flows, midpoint impacts, and endpoint impacts. The completeness ensured by including unspecified residuals use fully quantifiable indicators that can be traced from source to sink, so verified input-output balances against measured totals. Each category in has a definition lowest level also unit measurement. Examples definitions units are illustrated an pathway model with starting point “Undernutrition”. This demonstrates role development characterisation factors.
