feat: v0.4.0 — Scope 3 embodied carbon, water tracking, binary build by omrdev1 · Pull Request #10 · omrdev1/greenops-cli

What this closes

The two outstanding items from the original roadmap: embodied carbon (Scope 3) and water consumption tracking. Plus the binary build workflow. Nothing removed, everything additive.

1. Scope 3 Embodied Carbon

Every resource now reports manufacturing lifecycle carbon alongside operational carbon:

embodied_gco2e/month = (1,200,000g / 35,040h lifespan / 48 vCPUs) × vcpus × 730h

Source: Cloud Carbon Footprint DELL R740 baseline (v3)
ARM (Graviton) applies 20% discount — smaller die size + lower manufacturing TDP
All 40 instances in factors.json updated with embodied_co2e_grams_per_month

2. Water Consumption

water_litres = (W_effective × 730h / 1000) × WUE_litres_per_kwh

Source: AWS 2023 Sustainability Report (WUE by region)
WUE applied to IT load before PUE, matching AWS definition
All 14 regions updated with water_intensity_litres_per_kwh
Range: eu-north-1 (0.10 L/kWh) → ap-south-1 Mumbai (0.72 L/kWh)

3. Updated PR Comment Output

The live PR comment now shows all four dimensions:

Metric	Monthly Total
🔋 Scope 2 — Operational CO2e	7.06kg
🏭 Scope 3 — Embodied CO2e	1.88kg
🌍 Total Lifecycle CO2e	8.93kg
💧 Water Consumption	7.5L
💰 Infrastructure Cost	$126.29/month

Resource breakdown table adds Scope 3 and Water columns.

4. Binary Build Workflow

.github/workflows/release-binaries.yml — triggers on v* tags:

Builds 5 platform binaries via Bun compile
Smoke tests each binary (--version, --coverage)
Attaches to GitHub Release via softprops/action-gh-release@v2
Platforms: linux-x64, linux-arm64, darwin-arm64, darwin-x64, windows-x64

5. Documentation

METHODOLOGY.md: full rewrite with Scope 2/3 formulas, water formulas, worked examples, WUE table per region, recommendation scoring formula, full data sources table, known limitations
README.md: full rewrite with real live terminal output showing all dimensions, binary install section, quickstart, policy, coverage matrix

Tests

63 tests, 63 passing. json.test.ts now uses the real engine — no mock data.

Recommendations

`aws_instance.web`

Current: m5.large in us-east-1
Suggested: m5.large in eu-north-1
Scope 2 Impact: -4.21kg CO2e/month | +$2.92/month
Rationale: Moving m5.large from us-east-1 to Europe (Stockholm) (eu-north-1) reduces Scope 2 grid carbon intensity from 384.5g to 8.8g CO2e/kWh, saving 4215g CO2e/month (note: cost increases by $2.92/month). Water consumption also decreases by 3.6L/month.

`aws_instance.worker`

Current: m6g.large in us-east-1
Suggested: m6g.large in eu-north-1
Scope 2 Impact: -2.68kg CO2e/month | +$2.19/month
Rationale: Moving m6g.large from us-east-1 to Europe (Stockholm) (eu-north-1) reduces Scope 2 grid carbon intensity from 384.5g to 8.8g CO2e/kWh, saving 2681g CO2e/month (note: cost increases by $2.19/month). Water consumption also decreases by 2.3L/month.

Emissions calculated using the Open GreenOps Methodology Ledger v1.3.0. Scope 2 (operational) and Scope 3 (embodied) emissions tracked. Water consumption estimated from AWS 2023 WUE data. Math is MIT-licensed and auditable. Analysed at 2026-03-27T18:57:09.985Z.
