IoT enabling households track, verify, and monetize decarbonization

Problem

Roughly four billion people still lack access to clean cooking, relying on biomass, charcoal, or kerosene that harms health and forests. Decarbonizing cooking could cut more emissions than the global aviation industry, yet the sector has lagged badly. The core obstacle is data integrity: cookstove carbon claims have leaned on sampling and self-reported estimates held by project developers, fueling over-crediting and eroding buyer trust in the credits these projects generate.

Solution

ATEC reframes clean cooking as an untapped carbon asset that can only be realized if the climate claim is reliably tracked. Its patented IoT eCook devices capture 100% usage data on every unit, digitally sign and encrypt it, and send it straight to verifiers as an independent, tamper-proof dataset. Integrated with Hedera Guardian and Gold Standard’s metered methodology, this converts each device’s activity into a fully auditable, scalable carbon credit.

Digitization of carbon credits based on irrefutable dMRV data can dramatically improve accuracy and transparency in carbon markets by measuring 100% of devices 100% of the time. ATEC and its partners look forward to continuing to build the tech that solves trust in carbon markets, unlocking climate finance at scale for those that both need and deserve it the most – women across the Global South.

From estimate to evidence

Cookstove carbon has long suffered a credibility problem. A 2023 University of California, Berkeley
study found pervasive over-crediting across cookstove methodologies, driven by low data veracity
and an over-reliance on sampling. Because the underlying dataset typically sat with the project
developer, it could be altered before verification. ATEC’s hardware closes that gap by generating a
complete, device-level record that is signed and encrypted at source, then transmitted directly to a
verifier’s server. The result is a carbon credit with full data veracity and immutable characteristics,
engineered for transparency and therefore for scale.

A single digitised workflow

ATEC’s IoT data feeds directly into Hedera and Hedera Guardian, where digitized, open-source methodologies manage the full carbon project lifecycle. This lets ATEC interact with validation and verification bodies, certifiers, and standards bodies in one connected workflow, replacing the PDFs, spreadsheets, and siloed records that obscure data as volumes grow.

The approach won first place at the 2023 Sustainable Blockchain Summit Hackathon and positions ATEC for the next wave of carbon-data integrity requirements, giving buyers and communities end-to-end traceability of both the emission reduction and the finance that flows back to it.

Proof at scale: the ENGIE agreement

ATEC and ENGIE’s Global Energy Management & Sales (GEMS) division signed a long-term agreement for up to 11.5 million tons of Gold Standard digital MRV carbon credits from eCook devices in Bangladesh and Cambodia – the first major deal under Gold Standard’s metered methodology, which Berkeley rated the most accurate for cookstoves. Credits are tracked in real time through ATEC’s carbon dashboard, giving buyers unprecedented assurance that a ton is genuinely a ton.

Why Hedera?

ATEC needs an infrastructure layer that is transparent, low-cost, and credible enough for institutional carbon buyers – and that does not undermine the climate benefit it is trying to certify. Hedera’s energy-efficient, carbon-negative public network meets that bar while handling the high data volumes generated by a distributed fleet of connected devices.

Through Guardian, Hedera provides digitised, open-source methodologies and an auditable end-to-end trail from device to retirement. That lets ATEC bypass fragmented, manual processes and present buyers like ENGIE with a verifiable, real-time view of credit quality – the foundation of trust the voluntary carbon market urgently needs.
