| Framework | Focus | Packaging Metrics | Best For |
|---|---|---|---|
| GRI (Global Reporting Initiative) | Most widely used globally | GRI 306: Waste (2020) — requires waste generated, diverted, and directed to disposal by type and method. | Companies with broad stakeholder reporting needs. Required by many EU sustainability directives. |
| SASB (Sustainability Accounting Standards Board) | Investor-focused | Industry-specific metrics. For consumer goods: packaging lifecycle impacts, recyclability rates. | Publicly traded companies or those seeking institutional investment. Now part of ISSB/IFRS. |
| CDP (Carbon Disclosure Project) | Climate-focused | Scope 3 Category 1 (purchased goods) and Category 5 (waste in operations). Packaging materials in both. | Companies responding to investor or customer CDP questionnaires. Scoring from A to D-. |
| TCFD (Task Force on Climate-related Financial Disclosures) |
Packaging waste falls primarily into three Scope 3 categories under the GHG Protocol. Most companies focus on Category 5 (waste in operations), but inbound and outbound packaging also contribute to Categories 1 and 12.
Category 1: Purchased Goods & Services
Emissions from producing packaging materials you purchase — pallets, boxes, wrap, containers.
Calculation: Weight of material purchased x emission factor per kg for that material type.
Example: Buying 10,000 new wood pallets at ~27 kg each x 0.26 kg CO2e/kg = ~70 MTCO2e.
Category 5: Waste Generated in Operations
Emissions from disposing of packaging waste — landfilling, incineration, or recycling.
Calculation: Weight of waste by disposition x EPA WARM emission factor for that disposition method.
Example: Landfilling 50 tons of wood pallets = ~50 x 0.16 MTCO2e/ton = 8 MTCO2e. Recycling the same = -0.44 MTCO2e/ton (net negative).
Category 12: End-of-Life Treatment of Sold Products
Emissions from packaging that ships with your product and is disposed of by the end customer.
Calculation: Weight of outbound packaging x assumed disposition rates x emission factors.
Example: If 60% of outbound pallets are returned/reused and 40% landfilled, calculate each stream separately.
The EPA Waste Reduction Model (WARM) calculates GHG emission reductions from different waste management practices. Negative values indicate net emissions avoided compared to baseline (landfill for most materials).
| Material | Landfill | Recycle | Combust | Notes |
|---|---|---|---|---|
| Wood (pallets, crates) | 0.16 MTCO2e/ton | -0.44 MTCO2e/ton | -0.41 MTCO2e/ton | Recycling wood avoids emissions from virgin lumber production. Negative = net emissions avoided. |
| Corrugated Cardboard | 0.04 MTCO2e/ton | -3.14 MTCO2e/ton | -0.41 MTCO2e/ton | Corrugated has the highest recycling benefit due to high virgin production emissions. |
| HDPE (plastic pallets, drums) | 0.04 MTCO2e/ton | -1.32 MTCO2e/ton | -0.81 MTCO2e/ton | Plastic recycling avoids petroleum extraction and processing emissions. |
Double-counting: Material weighed at pickup and again at processing facility. Use one measurement point consistently.
Contamination not deducted: Recycler rejects 10% but you report 100% diverted. Deduct rejection rates from totals.
Mixing recycling and reuse: A reused pallet avoids more emissions than a recycled one. Track separately for accuracy.
Ignoring transportation emissions: Hauling waste 200 miles to a recycler has its own carbon cost. Include logistics in net calculations for completeness.
Using outdated emission factors: EPA updates WARM periodically. Verify you are using the most recent version.
Scale Tickets
Weight verification at pickup or delivery. Primary data source for tonnage reporting.
Retention: 3 years minimum. 5 years recommended for audit trail.
Diversion Certificates
Recycler-issued documentation confirming material was diverted from landfill. Specifies disposition method.
Retention: 3 years minimum. Required for GRI 306 and CDP disclosures.
Waste Manifests
Tracking documents for regulated waste streams. Required by EPA for hazardous waste (not typically needed for pallets/packaging).
Retention: 3 years (EPA requirement for hazardous waste manifests).
Vendor Certifications
Recycler permits, licenses, and environmental compliance documentation. Verifies your downstream partner is legitimate.
Retention: Current plus one prior year. Request updated annually.
Photos / Load Documentation
Visual record of material quality, staging, and loads. Useful for contamination disputes and audit support.
Retention: 1 year. Store digitally with date and location metadata.
| Level | Description | Cost | Credibility |
|---|---|---|---|
| Internal Review | In-house team validates data and methodology. No external party involved. | Low | Baseline — acceptable for internal reporting and initial ESG disclosures. |
| Limited Assurance | Third-party auditor performs inquiries and analytical procedures. Less rigorous than reasonable assurance. | Moderate | Standard for most voluntary sustainability reports. Acceptable for CDP, GRI. |
| Reasonable Assurance | Full third-party audit with detailed testing of data, systems, and controls. | High | Equivalent to financial audit rigor. Required by some EU regulations (CSRD). |
| ISO 14064 Certification | GHG inventory certified to ISO standard by accredited body. | High | Gold standard for GHG claims. Provides internationally recognized certification. |
Standardize categories
Define material buckets: wood, corrugated, plastic, metal. Use consistent naming across all sites.
Capture weights
Record weights or counts per pickup with date and location for traceability. Use scale tickets as primary source.
Request certificates
Collect diversion certificates and scale tickets from recyclers monthly. These are your audit trail.
Convert to CO2e
Use EPA WARM model emission factors to calculate avoided emissions. Apply factors specific to each material and disposition method.
Publish dashboards
Share monthly dashboards internally and year-end summaries for annual reports. Automate data pipelines where possible.

Employees
Focus on tangible impact — "We diverted X tons from landfill, equivalent to Y garbage trucks." Use visual comparisons.
Channel: All-hands meetings, break room signage, internal newsletter
Leadership / Board
Lead with cost savings and risk reduction. Tie to strategic goals. Include year-over-year improvement and comparison to industry benchmarks.
Channel: Quarterly business reviews, board ESG updates, annual sustainability report
Investors
Frame as risk mitigation and regulatory readiness. Use framework-aligned metrics (GRI, SASB, CDP scores). Show trend lines, not just snapshots.
Channel: Annual report, CDP disclosure, investor presentations, ESG ratings submissions
Customers
Emphasize supply chain sustainability and shared goals. Provide certificates they can use in their own reporting (Scope 3 Category 1 data).
Channel: Sustainability questionnaire responses, RFP attachments, customer portal
Regulators
Demonstrate compliance with waste reporting requirements. Use conservative estimates and third-party verified data.
Channel: Regulatory filings, permit renewals, compliance documentation
We can generate quarterly reports from your pickup data with all metrics ready for ESG disclosure.
