To achieve universal sanitation, as covered in SDG 6 target 6.2, one important piece of information to know is what expenditure is required to achieve it – how much is needed, where it is needed, and when it is needed.
As progress is made towards the SDG targets, new estimates are needed to assess what is the current funding gap and also to support advocacy efforts to fill the gap.
This study by UNICEF’s Guy Hutton and water specialist Mili Varughese provides an update on the required expenditure to meet the 2030 global targets on household sanitation.
