Measure it. Understand it. Reduce it.
BelleTech is a climate-first studio. We've planted over 5,000 trees, convene climatetech builders at the Tech4Green Summit, and we're now building the BelleTech Carbon Calculator — software and hardware that turn everyday emissions into action.
Carbon you can see.
Flagship Climate Product
BelleTech Carbon Calculator
Real-time carbon intelligence — in software, soon in hardware.
A smart, eco-friendly system that measures your environmental impact and helps you reduce it in real time. It tracks CO₂, temperature, humidity, air quality, energy use, light, noise and indoor wind speed, then uses AI to recommend precise, achievable reductions. The web version is live today; the wall-mounted hardware — 200×200×45mm, aluminium framed, Wi-Fi and cloud sync — is in development for homes, offices, schools and industry.

Community & Climate
Tech4Green Summit:
Inspiring the next wave of climatetech.
Our flagship convening of founders, researchers and policy makers building the next decade of climate technology — alongside our ongoing reforestation work, now past 5,000 trees planted.

Alongside the Mission
Side projects.
Climate is the heart of BelleTech — but we also build small, useful tools for problems we can't ignore: food waste and maternal wellbeing.
FoodShare
A quiet logistics layer for surplus food.
Businesses and households list food that would otherwise be wasted. Verified NGOs are matched by proximity and capacity, then routed for pickup.

MamaCare
Personalised care, every trimester.
A gentle web companion for pregnant women — tailored nutrition, movement, mental health check-ins and week-by-week guidance.

Research in motion.
Everything we ship begins as a climate question worth answering. Here's what we're studying right now, and how far along we are.
Carbon Calculator hardware
Sensor selection, calibration and low-power design for an accurate indoor CO₂ and air-quality monitor built for African grids.
Prototyping — schematic and enclosure design underway
AI reduction models
Turning raw sensor and energy data into recommendations people will actually act on, tuned to local energy mixes.
In research — early models under evaluation
Reforestation measurement
Verifiable tracking of survival rates and sequestration for the trees we plant, beyond headline counts.
Field pilot — data collection in progress
From the lab to the landscape.
