the UN observes today but the "container-based sanitation coalition" is key for global "ecological sanitation." ....vermicomposting toilets, ISO 30500-compliant “reinvented” toilet... Sanitation is starting to make its mark in carbon markets. The Sanergy Collaborative, through Fresh Life and its treatment operations, earned the first carbon credits for container-based sanitation (CBS) and related treatment. Meanwhile, SOIL’s model in Haiti demonstrates an alternative path for smaller implementers – selling verified climate impacts directly to buyers outside formal markets. https://fresh-life.org/ Very fascinating that ecological sanitation is now getting funding by selling "carbon credits"!!! All the best,

https://www.un.org/en/observances/toilet-day
3.4 billion people still don’t have a safe toilet.... Unsafe water, sanitation and hygiene are responsible for the deaths of around 1,000 children under five every day. (WHO, 2023)...At the current rates of progress, 3 billion people will still be living without safe toilets in 2030. (WHO/UNICEF, 2025)

Let’s be honest: the toilet is often much more than we give it credit for. It’s where we hide for a moment of quiet, flip through a book, escape a noisy room, or catch our breath in the midst of a holiday work party. But for billions of people, a safe, private place to do even the most basic of human functions is still out of reach.

Introduction
- — by 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations;
- — by 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.
1 Scope
- a) collects, conveys and fully treats the specific input within the NSSS, to allow for safe reuse or disposal of the generated solid and liquid outputs, and the safe emission of air, noise and odour outputs;
- b) is designed to operate without being connected to a networked sewer or networked drainage systems.
- — guidelines for selection, installation, operation and maintenance, and management of NSSS;
- — requirements for the amount or type of energy or resources to recover;
- — transportation of treated output outside of the NSSS (e.g. manual transport, transportation by truck or trunk pipes) for further processing, reuse, or disposal;
- — treatment processes taking place at another location separate from that of the frontend and backend components;
- — external reuse and disposal of NSSS output;
- — the plane or surface (e.g. flooring, concrete pad) upon which a fully assembled NSSS is situated;
- — NSSS constructed in situ without prefabricated parts.
