The Environmental Firewall for AI. Built by one person, on an iPhone and a Mac Mini, to solve a problem that affects every enterprise deploying AI at scale.
In early 2026, as mandatory CSRD limited assurance requirements came into force across Europe, a structural problem became clear: enterprises were deploying AI agents at scale with no mechanism to govern, measure, or verify the carbon emissions those agents were generating.
Existing tools could estimate emissions after the fact. None could prevent them in real time. None could produce the cryptographically verifiable audit evidence that CSRD limited assurance requires.
ACERM was built to close that gap — at the hardware layer, before emissions occur, with every decision sealed in a tamper-evident chain.
ACERM was conceived, designed, and built entirely by Terral Henry — on an iPhone XR and a Mac Mini. No venture capital. No team. No office. Just a clear problem, a patent, and a working product.
The UK Patent GB2610865.4 was filed on 9 May 2026, covering 11 claims across the Environmental Firewall architecture — from hardware-layer interception to cryptographic audit chain to Carbon Flexibility Certificate issuance.
Production V1 was validated in a live operational environment in May 2026, governing 1,000+ inference requests with verified carbon avoidance of 73.6kg CO₂e and a confirmed sub-millisecond enforcement latency of 0.857ms.
A mandatory network chokepoint between AI agents and upstream providers. Hardware-native. Cannot be bypassed by software updates or agent logic. Enforces carbon governance at the infrastructure layer — before emissions occur.
ACERM does not merely restrict — it optimises. By deferring low-priority workloads to periods of grid abundance, it maximises carbon efficiency without sacrificing operational capability. Avoided carbon is tokenised into tradeable Carbon Flexibility Certificates.
Every enforcement decision is recorded in a SHA-256 sequential hash chain. Tamper-evident, independently verifiable, and suitable for ESRS E1 limited assurance engagement. The audit trail exists from day one — not retroactively constructed.
Filed with the UK Intellectual Property Office on 9 May 2026. The patent covers 11 claims across the core ACERM architecture — the first patent specifically addressing real-time carbon governance for AI inference at the hardware layer.
ACERM's goal is not to report on AI carbon emissions after the fact. It is to make high-carbon AI inference structurally impossible during periods of grid stress — and to provide cryptographic proof that governance occurred.
Shadow Audit mode gives you 7 days of verifiable AI emissions data with zero enforcement and zero disruption. Your first CSRD-ready Category 11 disclosure starts from day one.
The SHA-256 audit chain provides tamper-evident, independently verifiable evidence suitable for limited assurance under ISAE 3000. Every decision traceable from genesis to present.
Stochastic re-entry prevents synchronised demand surges when grid conditions improve. ACERM nodes don't all resume simultaneously — protecting National Grid frequency stability.
