Signina × DelAgua — Tubeho Neza Impact

Investor legacy

From European belief to Rwandan hearths

Early Signina Capital investors backed a thesis that patient capital could seed climate and health infrastructure at household scale.

That bet helped build the platform behind DelAgua’s Tubeho Neza programme — free, high-performance Rwanda cookstoves for rural families who could never have bought clean cooking hardware over school fees or healthcare.

Today the story is measured in cleaner air, lighter fuel loads, protected forests, and Verra-verified carbon finance that keeps the clean cooking impact flywheel turning for Signina investors’ living legacy.

Tubeho Neza — “live well”

On the public record Historical Signina investor capital was held as preference shares in DelAgua Water Testing Ltd (UK Companies House 05940720) — the UK vehicle that helped seed the platform behind Tubeho Neza.

The arc

How belief became distribution

A simple chain — from investor conviction to community health workers at the door — that still delivers every day.

Patient capital

Early Signina Capital investors funded the architecture for scale — patient capital behind DelAgua Water Testing’s platform thesis, not a one-off charity drop.

Platform & partnership

DelAgua built Tubeho Neza with the Government of Rwanda across nearly every district.

Free at the point of need

High-quality stoves reach households who would otherwise stay on three-stone fires.

Verified climate finance

VCS-certified credits fund education, CHWs, monitoring — and the next wave of stoves.

Impact in numbers

Tubeho Neza, measured

Featured figures from DelAgua’s public impact materials — the scale early capital helped make possible.

To Date

0 stoves distributed to households

0 lives improved

Our Stoves By Numbers

0 reduction in household air pollution when using the stove outdoors

0 reduction in cookstove emission exposure among children

0 reduction in diarrhoea in children under 5 when using boiled water

0 less wood required than a traditional 3-stone fire

On Project Completion

0 of forestry saved annually — an area the size of Manhattan

0 football pitches of forest protected each year

0 tons of CO₂ saved annually

The same story Verra tells in its Rwanda case study — health, forests, and high-integrity carbon finance working as one system.

Featured “To Date” figures (1.8 million stoves; 7 million lives) per DelAgua public materials / impact infographic. Verra’s case study (July 2026) cites 1.7 million households with a stove and 6.8 million people impacted — earlier programme snapshots that may lag the latest DelAgua totals. Percentage and completion figures also from DelAgua public materials; Verra additionally notes ~3.1 MtCO₂e reduced annually under current verification framing.

Verified impact

How Verra frames Tubeho Neza

Independently told on Verra’s case-study desk: free clean cookstoves, community health workers, and VCS-certified carbon finance that funds the programme at scale.

Live well, free of charge

Tubeho Neza (“live well” in Kinyarwanda) delivers high-performance cookstoves to rural households who cannot afford the upfront cost — replacing three-stone fires that drive smoke exposure and long firewood walks.

Health, time, and forests

Verra highlights ~71% less firewood, sharply lower household air pollution, and lighter fuel collection for women and children — with education and follow-up through thousands of community health workers.

Integrity through VCS

Projects registered under Verra’s Verified Carbon Standard (including Projects 3699 and 4150) use methodology VM0050 so emission reductions track real, household-level stove use — the credits that keep free distribution possible.

Immediate, multi-benefit impact

As Verra’s energy lead puts it: few interventions change lives as immediately as a clean cookstove — climate finance delivering health and opportunity while cutting emissions at scale.

What capital made possible

Homes, health workers, cleaner air

Tubeho Neza pairs every stove with education and support through community health workers — so the technology is used, trusted, and lasting.

Education at the door

CHWs visit families to teach safe use — Verra notes 8,000+ local jobs for community health workers supporting the programme.

Less smoke, less wood

Up to 73% less household air pollution outdoors; 71% less wood than open fires.

Free at the point of need

Stoves reach rural households who could not otherwise choose a stove over school fees or care.

Climate & forests

Carbon finance that keeps kitchens clean

High-integrity carbon credits fund free distribution — a model that turns climate finance into daily dignity.

On project completion, DelAgua materials describe saving 64 km² of forestry annually and 4.08 million tons of CO₂ each year — while families cook with far less firewood.

That flywheel — capital → stoves → verified credits → more stoves — is the lasting architecture early investors helped make possible.

For the Signina community

Your capital has a living legacy

“Tubeho Neza” — live well.

To every early Signina Capital investor: thank you. The kitchens lit, the hours of firewood saved, and the cleaner air in rural Rwanda are part of what your belief helped unlock.
