Help communities measure carbonclearly, manage finely, plan paths, engage residents, evaluate outcomes
A community-level dual-carbon platform for governments (ecology, housing, urban management), sub-districts, property managers and operators. For both retrofits and new communities, built on proven MeetCarbon Cloud capabilities for accounting, energy control, resident carbon-benefit programmes and near-zero-carbon evaluation.
Policy and standards
Functions are designed against national and local policy and standards, as the basis for acceptance and compliant outputs
10 Level-1 / 46 Level-2 indicators; a binding drop in community CO₂; carbon statistical accounting and public disclosure.
Near-zero-carbon community indicator set; resident recycling-points participation; education-activity counts.
Personal and institutional carbon accounts, scenario registration, issuance and points conversion, mall and benefit redemption.
Core and general indicators; accounting boundary and emission factors; build-and-operate process.
Near-zero-carbon community construction and operations: evaluation system and composite score.
Building carbon calculation standard: emission-factor method for the operating stage.
Reduction-information management, points, and mall administration.
Digital technology for green low-carbon communities: sensing / platform / management-service layers.
Switchable international community accounting and carbon-neutrality framing, producing comparable inventories and net-zero statements for outbound projects and cross-border disclosure.
A built-in policy and standards hub holds interpretations, a technical-standards library, construction and accounting methods, and module-level compliance mapping. Business pages can “view the basis” for traceability and inspection packs. Domestic, Hong Kong and international standard sets can run in parallel.
Six community dual-carbon pain points
Targets have reached grassroots communities that lack tools, data and incentives
Emissions cannot be counted clearly
No shared boundary or ledger. Building energy, transport, street lighting, waste and sinks sit in silos, so per-capita and per-area intensity never forms.
Energy cannot be seen
Common-area lighting, lifts, pumps and charging lack submetering and live monitoring, so leaks and anomalies are found late.
No path to cut carbon
No target breakdown or peaking-path simulation. Retrofit measures lack estimated reductions and priority ranking.
Residents do not take part
Green behaviour is unquantified and unrewarded, so awareness does not land and recycling-points participation stays low.
Outcomes are hard to evaluate
Cannot benchmark the national near-zero-carbon indicator set, no self-evaluation report, nothing to disclose to superiors or residents.
Build cost is high
Stock communities have tight retrofit budgets. Delivery must stay light and reuse existing smart-community assets.
Five capability domains
From the carbon ledger to green energy assets across the community dual-carbon life cycle
Carbon ledger
Full-scope monitoring, accounting, evidence and annual ledgers for building energy, transport, street lighting, waste and sinks.
Smart energy control
Electricity, water, gas, cooling and heat submetering, live common-area monitoring, efficiency analysis, anomaly alerts and diagnostics.
Resident carbon-benefit programmes
Personal carbon accounts, reduction scenarios, points rules, mall and benefit redemption to activate everyday low-carbon behaviour.
Near-zero-carbon evaluation
Core and general indicators, pass-rate tracking, self-evaluation reports, inspection tasks and public disclosure.
Green energy and low-carbon assets
Community-scale access and operations for distributed PV, storage, charging, smart lighting, eco-roofs and smart recycling stations.
Five closed business loops
From boundary setup to inspection disclosure — policy-driven data governance
Community accounting and inspection
Enter or ingest activity data by boundary → auto-account with emission factors → annual ledger and self-evaluation → benchmark near-zero-carbon indicators → disclose to superiors and residents.
Common-area energy monitoring and saving
Connect submeters → live lighting, lift, pump and charging loads → anomaly alerts to work orders → diagnostics and measure tracking.
Resident reduction and incentive loop
Residents authorise scenarios → reductions convert to points by methodology → mall redemption → community reduction assets accumulate.
Targets and reduction pathways
Set peaking / cut targets → split across energy, buildings, transport and waste → measure library estimates reductions → scenario simulation and peaking path.
District supervision and assessment
Compare, rank, warn and assess multiple communities on emissions, pass rates and carbon-benefit participation.
Four-layer architecture
Aligned with digital technology for green low-carbon communities and the overall digital carbon-management framework
IoT sensing
Meters for electricity, water and gas; PV inverters; chargers; smart recycling stations; solar street lights; environmental sensors.
Data aggregation

Three terminals
B-end community / property admin, C-end resident carbon-benefit mini-app, dashboards for government, operators and communities.

AI assists decisions and speed. Accounting issuance, inspection reports and work-order execution keep human review and approval, with auditable traces on key actions. Domestic / Hong Kong / international languages and standard framings are supported.
Accounting methodology and indicators
Chapter 6 of the near-zero-carbon community guide and GB/T 51366, emission-factor method

Case: Huansha Lake dual-carbon EOD belt
Wuchang District, Wuhan · 15 residential communities · ~750,000 m² · AI + green low-carbon demonstration
The Huansha Lake EOD uses a four-layer sensing–transport–platform–application stack and a district carbon-management platform covering collection, live monitoring, energy statistics, smart energy management, fault diagnosis and intelligent monitoring. This system’s accounting, energy control, low-carbon assets, carbon-benefit, map and dashboards map to the project’s three workstreams: public-building efficiency, district low-carbon scenes, and the carbon platform. Resident carbon-benefit can link with local programmes such as Wu Carbon Jianghu / Wu Carbon Tong, closing the behaviour–points–incentive loop.
