You are a senior legal consultant specializing in Canadian environmental law and sustainable supply chain management, with expertise in the Canadian Environmental Protection Act (CEPA), Federal Sustainable Development Act, and provincial green procurement standards. 

Create a comprehensive "Environmental Procurement Policy" for [ORGANIZATION_NAME], operating in the [INDUSTRY_SECTOR] sector within [PROVINCE_TERRITORY], Canada. The organization has an annual procurement budget of [PROCUREMENT_SPEND_RANGE] and prioritizes: [PRIORITY_AREAS].

**STRUCTURE REQUIREMENTS:**
Generate a professional policy document (1500-2500 words) containing:

1. **EXECUTIVE SUMMARY** - Brief rationale linking procurement to Canada's 2030 Emissions Reduction Plan and net-zero targets

   - Canadian Environmental Protection Act, 1999 (CEPA) relevant provisions
   - Treasury Board of Canada Secretariat green procurement requirements
   - Applicable [PROVINCE_TERRITORY] environmental legislation (e.g., Environmental Bill of Rights, waste diversion regulations, carbon pricing)
   - Trade Agreement obligations (CUSMA, CETA, CPTPP) regarding environmental criteria

3. **POLICY SCOPE & DEFINITIONS** - Define 'environmentally preferable purchasing,' 'life-cycle costing,' and 'embodied carbon' within Canadian context

4. **PROCUREMENT TIERS & CRITERIA** - Create tiered evaluation framework:
   - Mandatory environmental specifications for high-impact categories (IT equipment, vehicles, construction, food services)
   - Weighted scoring criteria (suggest 15-30% weighting for environmental factors)
   - Third-party certification recognition (EcoLogo, Energy Star, Forest Stewardship Council, Green Seal)

5. **VENDOR REQUIREMENTS** - Include clauses for:
   - Supplier environmental disclosures (GHG emissions, waste management)
   - Canadian Environmental Sustainability Indicators (CESI) alignment
   - Local/regional supplier preferences within trade agreement bounds

6. **IMPLEMENTATION PROTOCOL** - Provide 12-month rollout plan with:
   - Phase 1: Baseline assessment and priority category identification
   - Phase 2: Template RFP language integration
   - Phase 3: Staff training on life-cycle assessment tools
   - Phase 4: Performance monitoring

7. **MONITORING & REPORTING** - Establish KPIs aligned with Federal Sustainable Development Strategy targets:
   - Percentage of contracts with green criteria
   - GHG reduction through procurement decisions
   - Waste diversion metrics
   - Annual public reporting structure

8. **EXCEPTIONS & FLEXIBILITY** - Define legitimate exemptions (emergency procurement, sole-source national security) with documentation requirements

**TONE & FORMAT:**
- Use formal policy language suitable for board approval
- Include [INSERT: specific commodity codes] placeholders where organization-specific product categories should be detailed
- Add footnotes citing specific Canadian regulations where compliance is mandatory vs. recommended
- Conclude with "Policy Review Cycle" recommending annual updates to reflect evolving carbon pricing and provincial extended producer responsibility regulations

**CONSTRAINTS:**
- Ensure recommendations respect Canadian trade agreement obligations (no explicit 'buy local' mandates that violate interprovincial/international trade)
- Address both federal and [PROVINCE_TERRITORY] specific waste reduction targets (e.g., single-use plastics ban compliance, organic waste regulations)
- Include Indigenous procurement considerations where applicable to environmental traditional knowledge
