Partner Programme

iThemba Kuluntu.

A carbon offset and clean water access programme. Gold Standard methodology, generated in South Africa, with socio-economic impact you can report.

The challenge

Most offsets happen
somewhere else.

Carbon liabilities are rising. The tax rate stepped up sharply at the start of 2026 and the offset allowance widened at the same time, so more organisations are looking at offsets than ever. The trouble is what is on the shelf. A great deal of it is generated far away, in a landscape a South African board has no line of sight into, and the category has taken real reputational damage from projects that turned out to be worth less than they claimed.

There is also a practical constraint that catches people out. Under South Africa's carbon offset regulations an offset only counts against carbon tax if the project is wholly undertaken in the Republic, sits outside an activity that is itself taxed, and is certified under one of three approved standards. An imported credit, however well intentioned, does not qualify.

PureFlow Amanzi is a carbon offset and clean water access programme in the rural Eastern Cape, run by iThemba Kuluntu NPC, a women-led Public Benefit Organisation. Households that currently boil water over wood receive gravity-fed filtration instead. Less wood burned means fewer emissions, and it also means safe water, less preventable illness, and hours given back to the women and caregivers who carry that burden. GCX is carbon technical advisory partner to the programme.

Why these credits

  • Generated in South Africathe origin requirement for carbon tax offsets
  • Gold Standard methodologyone of three standards recognised locally
  • Co-benefits you can seesafe water, health, schools, local livelihoods
  • Two budget lines, one projectcarbon and socio-economic development
  • Impact you can reportmeasured delivery, not a certificate alone
Structured against the regulation, methodology and reporting frameworks that govern offsets in South Africa

What you are buying

An emission reduction,
and everything attached to it.

The carbon is the instrument. What separates this from a generic credit is everything that has to happen on the ground to produce it.

01

The emission reduction

Households treating water by boiling burn wood to do it. Reliable filtration removes that need, and the emissions with it, continuously rather than as a one-off event.

02

South African origin

The programme runs in Port St Johns and Ingquza Hill in the Eastern Cape. That matters commercially as well as ethically: an offset must be generated in the Republic to count against carbon tax.

03

Safe water in the home

Gravity-fed, non-electric, chemical-free filtration, suited to rural conditions where power and consumables cannot be assumed. Lower exposure to unsafe water, and less preventable illness.

04

Time returned to women

Boiling costs time, fuel and money, and that burden falls most heavily on women and caregivers. Removing it is one of the most direct social returns the programme produces.

05

Schools and local livelihoods

Safe water reinforced in schools and ECD centres, alongside local assembly, distribution, onboarding and monitoring work that creates income-linked participation in the area.

06

Measurement and reporting

Household onboarding, follow-up support, delivery tracking and verification, so what you report rests on delivery rather than on an assumption.

Why it holds up

This category has an integrity problem.
That is exactly the point.

The methodology

An established Gold Standard methodology, not a bespoke one.

What that means

  • An existing safe water methodology, with registration work already initiated
  • Gold Standard tightened its biomass accounting rules through 2025 and 2026
  • We work to the current rules, not to expired pre-approved values
  • Conservative assumptions are worth more than optimistic ones in this market

The eligibility

Local origin and an approved standard are the two tests that matter.

What that means

  • The project is wholly undertaken in South Africa, as the regulations require
  • Gold Standard is one of three standards recognised for the offset allowance
  • The activity displaced is not itself subject to the carbon tax
  • Credits are cancelled and listed on the national registry before they can be claimed

The impact

Socio-economic delivery is the product, not a marketing wrapper.

What that means

  • Delivered by a registered Public Benefit Organisation already working in the area
  • A full implementation model: education, onboarding, aftercare and monitoring
  • Local assembly and distribution, so capability stays in the community
  • Outcomes you can put in front of a board or into a sustainability report

Volumes, pricing and the registry process are scoped per buyer against the current methodology. We would rather quote conservatively than revise downwards later.

How it fits

Advisory,
in the field.

Methodology selection, additionality, registration pathway, pricing basis and revenue structuring are the same disciplines whether the project is a corporate decarbonisation programme or a rural safe water rollout. GCX acts as carbon technical advisory partner here, which is the same work our Climate and Carbon team does for clients directly.

If you are weighing offsets as part of a wider carbon strategy, that conversation is usually better had before the purchase than after it. Offsets are the last step in a decarbonisation plan, not a substitute for one.

Who it is for

  • Organisations carrying a carbon tax liability
  • Sustainability and ESG teams sourcing credible offsets
  • CSI and socio-economic development budget holders
  • Boards wanting impact they can point at, locally
  • Companies reporting under IFRS S2 or GRI
  • Anyone burned by an offset that did not hold up

Offsets you can
stand behind.
