Background
Limno Tech and Water.org co-developed a concept note in 2021 outlining the need and opportunity to develop a standardized accounting method for the co-benefits of WASH with a similar rigger to the industry-accepted volumetric water benefit accounting (VWBA) method. In November 2021 a workshop was held with interested businesses and stakeholders where the concept was widely acknowledged as a beneficial step to strengthen the business case for investments in WASH. Limno Tech and Water.org then approached the CEO Water Mandate and WASH4Work to host a project to develop the standardized accounting method, to leverage the WASH expertise and business leadership on WASH via the WASH4Work initiative. The concept was approved by the WASH4Work Steering Group in April 2022.
Project Objectives:
- ” To strengthen the business case for investing in WASH; to go beyond beneficiary counting to a standardized method and guidance for identifying and accounting for the broader impacts, outcomes and benefits of investing in WASH such as: social, environmental, economic, health, well-being and resilience.
- ” To make more concrete and science-based linkages between the benefits of WASH access on water quality, quantity, replenishment, and resilience corporate water stewardship goals.
- “To embed into the method the integrated, systems-level approach of climate resilient WASH.
- ” To provide guidance for business on the use and implementation of the standardized accounting method.
