Six Community Pain Points
Dual-carbon goals reaching grassroots communities without tools, data or incentives
Carbon "unclear"
No unified boundary or ledger; building, transport, lighting, waste and sink data are fragmented, making per-capita and per-area metrics hard to derive.
Energy "invisible"
Common-area lighting, lifts, pumps and charging lack sub-metering and real-time monitoring; losses and anomalies go undetected.
No "pathway"
Lack of target breakdown and peaking simulation; retrofit measures lack reduction estimates and prioritization.
Residents "not engaged"
Green behavior is neither quantified nor incentivized; low participation in recycling and carbon-benefit programs.
Outcomes "hard to assess"
No alignment to near-zero-carbon indicator systems, no self-assessment reports, nothing to disclose upward or to residents.
High build "cost"
Limited retrofit budgets require lightweight upgrades reusing existing smart-community assets, avoiding reinventing the wheel.
Five Capability Domains
From carbon ledger to green energy assets, covering the full community dual-carbon lifecycle
Carbon data ledger
Full-scope monitoring, accounting, attestation and annual ledger for buildings, transport, lighting, waste and sinks.
Smart energy management
Sub-metering of power/water/gas/cooling, real-time common-area monitoring, efficiency analytics, alerts and diagnostics.
Resident carbon benefit
Personal carbon accounts, reduction scenarios, point rules, marketplace and redemption to activate low-carbon behavior.
Near-zero-carbon evaluation
Alignment to core/general indicator systems, compliance tracking, self-assessment reports and disclosure.
Green energy & low-carbon assets
Distributed PV, storage, EV charging, smart lighting, eco-roofs and smart recycling stations operated at community scale.
Five Business Scenario Loops
From boundary setup to audit-ready disclosure — a policy-driven data governance loop
Community accounting & audit readiness
Enter/ingest activity data by boundary, run factor-method accounting, produce annual ledger and self-assessment, benchmark to targets, then disclose.
Common-area energy monitoring & saving
Connect sub-meters, monitor lighting/lifts/pumps/charging, trigger anomaly alerts to work orders, and track diagnostics and measures.
Resident reduction & incentive loop
Residents authorize scenarios, reductions are quantified into carbon points, redeemed in the marketplace, accumulating community reduction assets.
Targets & pathway management
Set peaking/reduction targets, break them down by energy/building/transport/waste, size measures, and simulate peaking pathways.
Government area supervision
Cross-community comparison of emissions, compliance and engagement, with ranking, alerts and assessment across the district.
Four-Layer Architecture
Aligned with green low-carbon community digital technology and carbon-management platform frameworks
IoT Sensing
Meters, PV inverters, EV chargers, smart recycling stations, solar street lights and environmental sensors.
Data Aggregation

AI assists decisions and efficiency; carbon issuance, audit reports and work-order execution retain human review and approval with auditable logs; supports mainland / HK / international multilingual and multi-standard modes.
Accounting Methodology & Indicators
Emission-factor method under GHG Protocol GPC and ISO 14064 boundaries
Under the GHG Protocol GPC, Scope 1/2/3 emissions from stationary energy, transport and waste within the community boundary are quantified and reported at BASIC / BASIC+ levels; building operational carbon metrics follow ISO 16745 and interoperate with local factors.
E = Scope1 + Scope2 + Scope3 (BASIC+)E = Σ(activity data × emission factor)E ÷ resident population (tCO₂/cap·yr)(base year − current) ÷ base year × 100%Three-Terminal Integration
