Inventario GEI organizacional ISO 14064-1

ISO 14064-1:2018 specifies requirements for organizational GHG quantification and reporting. Applies to companies worldwide reporting GHG emissions per regulatory (Sustainability, CSRD/ESRS) or voluntary (CDP, SBTi) frameworks.

ISO 14064-1 scope: Organizational GHG inventory. Direct emissions (Scope 1), indirect energy emissions (Scope 2), other indirect emissions (Scope 3). All in CO2-equivalent (CO2e) terms per IPCC AR6 GWP.

Organizational boundary: Equity share approach (GHG emissions proportional to equity ownership) or control approach (financial or operational control). Choose one and apply consistently.

Reporting boundary: All facilities + operations within organizational boundary. Identify emission sources per Scope 1/2/3 categories.

Scope 1 (Direct emissions): Stationary combustion (boilers, generators), mobile combustion (vehicle fleet), fugitive emissions (refrigerants, SF6), process emissions (chemical, cement), direct land use. Accounting methodology: Activity data x emission factor = emissions. Activity data: fuel consumption, distance traveled, refrigerant refilled, materials used. Emission factors: per IPCC, EPA, DEFRA, IEA, local agencies.

Scope 2 (Indirect energy emissions): Purchased electricity, steam, heating, cooling. Two methods: location-based (national grid average) + market-based (supplier-specific, contractual instruments like RECs/Guarantees of Origin).

Scope 3 (Other indirect emissions): 15 categories per GHG Protocol. Upstream: purchased goods, capital goods, fuel + energy related, upstream transport, waste, business travel, employee commute, upstream leased assets. Downstream: downstream transport, processing of sold products, use of sold products, end-of-life treatment, downstream leased assets, franchises, investments.

Significance assessment: Determine which Scope 3 categories are significant (de-minimis threshold 5% per category, total 75% of all categories, or business relevance). Include significant categories in inventory.

Quantification methodology: Calculation-based (activity data x emission factor), spend-based (spend x EEIO emission factor), supplier-specific (supplier LCA data). Choice depends on data availability.

Base year + recalculation: Choose base year (typically founding or first reporting year). Recalculate base year for significant changes (>5% per category). Document recalculation policy.

Uncertainty management: Address uncertainty in activity data + emission factors. Use uncertainty quantification (e.g., 95% confidence interval). Document uncertainty sources.

GHG reduction target: Absolute target (CO2e reduction from base year) or intensity target (CO2e per unit of activity/product). Science-based target (SBTi) per Paris Agreement 1.5°C pathway.

B2B relevance: For B2B manufacturers + exporters, ISO 14064-1 compliant GHG inventory is mandatory per EU CSRD/ESRS, US SEC climate disclosure, UK TCFD-aligned reporting, customer Scope 3 inquiries.

B2B recommendation: For 2026 ESG-bound B2B orders, target ISO 14064-1 compliant GHG inventory: Scope 1+2 mandatory, Scope 3 significant categories (especially Category 11 product use + Category 12 end-of-life), base year + recalculation policy, SBTi-aligned reduction target, external verification (ISAE 3410 or ISO 14064-3).

Huella carbono producto ISO 14067

ISO 14067:2018 specifies requirements for product carbon footprint (PCF) quantification. Critical for B2B products where customer asks for product-level carbon data per EU CSRD/ESRS or voluntary frameworks.

ISO 14067 scope: Product carbon footprint. Quantifies GHG emissions per functional unit (declared unit) over product life cycle. Single issue: climate change only (no other environmental impacts).

Cradle-to-gate vs cradle-to-grave: Cradle-to-gate (raw material extraction to factory gate, manufacturer controls up to factory exit). Cradle-to-grave (full life cycle including use phase + end-of-life). Cradle-to-customer (raw material to customer delivery).

Functional unit vs declared unit: Functional unit = defined use (e.g. "1 kg of protective case protecting 5 kg equipment for 5 years"). Declared unit = physical unit (e.g. "1 piece of protective case weight 2.5 kg"). Cradle-to-grave uses functional unit.

PCF methodology: LCA (life cycle assessment) per ISO 14040/14044 principles. Goal + scope definition, life cycle inventory (LCI), life cycle impact assessment (LCIA), interpretation.

Product life cycle stages: (1) Raw material acquisition, (2) Manufacturing, (3) Distribution, (4) Use, (5) End-of-life treatment. Each stage has Scope 1/2/3 emissions.

Raw material acquisition: Material extraction, processing, transportation to factory. Includes Tier 1 + Tier 2 supplier emissions. Use supplier-specific data where possible, industry-average (e.g., ecoinvent, GaBi) otherwise.

Manufacturing: Factory energy use, process emissions, waste, water. Direct + indirect emissions. Electricity (location-based or market-based), heat, steam, compressed air, waste disposal.

Distribution: Transportation from factory to customer (incoming raw material + outgoing finished product). Per km, per kg, per mode (truck, rail, ship, air).

Use phase: Customer-side emissions during product use. For protective case = 0 (passive). For active product = significant (e.g., motor, refrigeration).

End-of-life: Disposal, recycling, incineration, landfill. Credit for recycled content + recyclability (avoided burden method or closed-loop approximation).

GHG gases: CO2, CH4, N2O, HFCs, PFCs, SF6, NF3. Convert to CO2e per IPCC AR6 100-year GWP.

Documentation: PCF report per ISO 14067 Section 6. Includes goal + scope, methodology, data sources, assumptions, results, critical review. Critical review by independent third party recommended for public claims.

Communication: ISO 14067 distinguishes product carbon footprint study (full report) vs product carbon footprint claim (public-facing claim with specific statements per ISO 14021 + ISO 14027).

B2B relevance: For B2B manufacturers, product carbon footprint PCF is increasingly requested by EU-bound customers per CSRD/ESRS. Required for EU Digital Product Passport per EU Ecodesign for Sustainable Products Regulation (ESPR) 2024/1781.

B2B recommendation: For 2026 EU-bound B2B orders, target ISO 14067 compliant PCF: cradle-to-gate scope (minimum) + cradle-to-grave (preferred for ESPR compliance), verified by third party per ISO 14071, declared in product specifications, aligned with customer PCF calculation methodology.

GHG Protocol Corporate Standard

GHG Protocol Corporate Accounting and Reporting Standard (developed by WRI + WBCSD, 1998 + 2004 revised + 2013 Scope 2 Guidance + 2011 Scope 3 Standard) is the global baseline for corporate GHG inventory. Most regulatory + voluntary frameworks reference GHG Protocol.

GHG Protocol scope: Corporate GHG inventory. Globally applicable to public + private sector. Used as basis by 90% of Fortune 500 companies reporting GHG inventory.

GHG Protocol + ISO 14064-1 alignment: ISO 14064-1 is the formal ISO standard, GHG Protocol is the global baseline. ISO 14064-1:2018 references GHG Protocol for Scope 3 categories. Both compatible.

GHG Protocol Scopes 1/2/3: Scope 1 = direct, Scope 2 = purchased energy, Scope 3 = value chain. Same as ISO 14064-1.

GHG Protocol Scope 3 Calculation Guidance: 15 categories with calculation methodology per category. Sub-categorized for specific industry applications.

GHG Protocol Scope 3 Standard + Technical Guidance: Tools for calculating Scope 3 across all 15 categories. Includes spend-based method, supplier-specific method, hybrid method, average-data method.

GHG Protocol Policy + Action Standard: Framework for assessing policy + actions on GHG emissions. For governments + companies setting internal carbon pricing.

GHG Protocol Mitigation Goal Standard: Framework for setting + tracking corporate GHG reduction targets. Compatible with SBTi.

GHG Protocol Protocol Chain: Cross-cutting methodologies for scope 1/2/3 + land use + removals. Includes updated IPCC AR6 GWP values.

GHG Protocol Sector Guidance: Sector-specific guidance for 10+ sectors (aluminum, cement, electric power, financial, food, ICT, iron + steel, oil + gas, pulp + paper, retail). Each has Scope 1+2+3 priority categories + calculation guidance.

GHG Protocol Cross-Sector Tools: Emission factors (DEFRA, EPA, IEA), stationery combustion tool, mobile combustion tool, fugitive emissions tool. Standardized tools for inventory compilation.

GHG Protocol Verification: Third-party verification per ISO 14064-3 + ISAE 3410 (limited + reasonable assurance). For SBTi, scope 1+2 required + Scope 3 optional but recommended.

GHG Protocol Reporting climate: Annual sustainability report per CDP, CSRD/ESRS, TCFD-aligned disclosure. Public disclosure recommended for transparency + stakeholder engagement.

B2B relevance: For B2B manufacturers + exporters, GHG Protocol compliance is the de facto global standard for GHG inventory. Required by EU CSRD, UK TCFD, US SEC climate disclosure, customer Scope 3 inquiries.

B2B recommendation: For 2026 global ESG-bound B2B orders, target GHG Protocol + ISO 14064-1 dual compliance: Scope 1+2 mandatory inventory, Scope 3 significant categories, base year + recalculation, SBTi-aligned target, external verification per ISO 14064-3 + ISAE 3410.

Verificación huella carbono + aseguramiento

External verification + assurance of GHG inventory + product carbon footprint is increasingly required by regulatory frameworks (CSRD, SEC) + voluntary frameworks (SBTi, CDP).

Verification standard: ISO 14064-3 (Specification with guidance for the verification and validation of greenhouse gas statements). Specifies verification approach for organizational + project-level GHG statements.

Assurance standard: ISAE 3410 (International Standard on Assurance Engagements 3410, Assurance Engagements on Greenhouse Gas Statements). Two levels: limited assurance (moderate confidence) + reasonable assurance (high confidence).

Verifier qualification: Lead auditor qualified per ISO 14064-3 + sector experience. Typically ANAB-accredited verifier for ISO 14064-3 or CPA firm registered for ISAE 3410.

Verification scope: Organizational boundary, Scope 1/2/3 categories, base year, recalculation policy, emission factors, data sources, calculation methodology, internal controls, uncertainty management.

Verification procedure: Risk assessment, materiality threshold, sampling strategy, recalculation checks, data verification, control testing, documentation review, on-site audit.

Verification opinion: Limited assurance (nothing came to our attention) vs reasonable assurance (in our opinion, fairly stated). For SBTi, reasonable assurance preferred for Scope 1+2.

Materiality: Typical materiality threshold 5% of total emissions or industry benchmark. Smaller organizations may use higher threshold.

Verification cycle: Typically annual. Mid-cycle monitoring if significant change.

PCF critical review: Independent expert review per ISO 14071 + ISO/TS 14071. Recommended for public PCF claims. Required by EU PEF (Product Environmental Footprint) methodology.

Documentation package: GHG inventory report, base year + recalculation policy, data sources + emission factors, calculation methodology, internal controls, verification opinion.

B2B relevance: For B2B manufacturers reporting to EU customers, external verification + assurance is increasingly required by CSRD/ESRS (limited + reasonable assurance) + SBTi (reasonable for Scope 1+2).

B2B recommendation: For 2026 ESG-bound B2B orders, target: external assurance by accredited verifier per ISAE 3410 limited assurance (minimum) or reasonable assurance (preferred). Annex C for non-financial reporting per CSRD/ESRS. 3rd-party verified PCF for product carbon footprint per ISO 14067 + ISO/TS 14071 critical review.

Science-Based Targets Initiative (SBTi) + TCFD

SBTi + TCFD are voluntary frameworks for science-based GHG reduction targets + climate-related financial disclosure. Increasingly adopted by EU + US companies.

SBTi (Science Based Targets initiative): Validates corporate GHG reduction targets per Paris Agreement 1.5°C pathway. Targets validated within 24 months of submission.

SBTi target types: Near-term target (5-10 year reduction, Scope 1+2 mandatory, Scope 3 if >40% of total emissions). Long-term target (typically 2050 net-zero, Scope 1+2+3 all categories).

SBTi methodology: Absolute Contraction Approach (ACA) or Sectoral Decarbonization Approach (SDA). Most companies use PCA + sector standards (cross-sector tools).

SBTi near-term: 50% Scope 1+2 reduction by 2030 from base year. Scope 3 if >40% of total must be addressed. Validated target within 24 months.

SBTi long-term: 90% Scope 1+2+3 reduction by 2050 from base year. Net-zero requires residual emissions offset by carbon removal credits (not reduction credits).

TCFD (Task Force on Climate-related Financial Disclosures): Voluntary framework for climate-related financial disclosure. Adopted by EU CSRD/ESRS + UK mandatory climate reporting + global investors.

TCFD pillars: (1) Governance (board + management oversight), (2) Strategy (climate risks + opportunities + scenario analysis), (3) Risk Management (climate risk identification + assessment + management), (4) Metrics + Targets (GHG inventory + climate metrics + SBTi-aligned targets).

TCFD scenario analysis: Per TCFD Guidance, scenarios include 1.5°C + 2°C + 4°C pathways. Use IEA + IPCC + Network for Greening Financial System (NGFS) scenarios.

TCFD disclosure: Recommended per TCFD aligned with annual sustainability report. Mandatory per UK Companies Act + EU CSRD/ESRS.

CSRD/ESRS (EU Corporate Sustainability Reporting Directive + European Sustainability Reporting Standards): Mandatory for EU companies meeting thresholds. ESRS E1 (Climate Change) requires GHG inventory + reduction targets + transition plan + scenario analysis + financial effects + risk management.

B2B relevance: For B2B manufacturers + exporters, SBTi + TCFD alignment is increasingly required by EU customers for supply chain alignment. CSRD/ESRS compliance mandatory for EU customers + large non-EU companies selling into EU.

B2B recommendation: For 2026 global ESG-bound B2B orders, target: SBTi-aligned near-term (50% Scope 1+2 by 2030) + long-term (90% Scope 1+2+3 by 2050) targets, TCFD-aligned disclosure (governance + strategy + risk + metrics), CSRD/ESRS E1 climate disclosure for EU customers.

Correlación maletín de protección

Protective cases used in B2B exports contribute to customer Scope 3 emissions (Category 1: purchased goods + services). ISO 14064-1 + ISO 14067 + GHG Protocol compliance enables customer to report their Scope 3 accurately.

Customer Scope 3 Category 1: Purchased goods + services. Protective case is a purchased good. Customer must include case cradle-to-gate emissions in their Scope 3 inventory.

PCF per ISO 14067: Cradle-to-gate PCF (raw material extraction to factory gate). Typical protective case PCF = 15-50 kg CO2e per kg of case (depending on material, manufacturing, transport).

Material-specific PCF: Stainless steel 304/316L (~6 kg CO2e/kg material, varies). Aluminum 5083/6082 (~12 kg CO2e/kg). Engineering plastic PP/PA (~25 kg CO2e/kg). PP ~25 kg CO2e/kg.

Manufacturing PCF: Assembly energy, packaging, factory emissions. Typically 1-3 kg CO2e per kg case.

Distribution PCF: Sea freight ~10 g CO2e/tonne-km, road freight ~60 g CO2e/tonne-km, air freight ~500 g CO2e/tonne-km. Shenzhen to Hamburg sea freight ~12-15 days = ~120 g CO2e/tonne-km x distance.

Use phase PCF: Passive case = 0 emissions. Active case (with refrigeration + electronics) = significant. Typical B2B protective case = 0 use phase.

End-of-life PCF: Recycling (net credit for avoided virgin material), landfill (CH4 emissions), incineration (CO2 emissions). Credit for recycled content ~50-90% reduction.

PCF improvement strategies: Lightweight design (material reduction), recycled content (15-90% reduction), renewable energy manufacturing (50-100% reduction), efficient distribution (sea vs air 50x), durability (longer life reduces per-year PCF).

B2B compliance: For B2B protective case manufacturers, ISO 14064-1 + ISO 14067 + GHG Protocol compliance includes: corporate GHG inventory, product carbon footprint per product line, reduction targets, SBTi alignment, CSRD/ESRS E1 disclosure (if EU customer).

Documentation: PCF per ISO 14067 (cradle-to-gate), verification per ISO 14064-3, public disclosure, customer communication.

B2B relevance: For B2B protective case sales to large EU customers (CSRD/ESRS compliant), supplier must provide product carbon footprint data + verified GHG inventory + SBTi-aligned reduction targets. Increasingly required in B2B RFPs.

B2B recommendation: For 2026 global B2B orders, target: ISO 14064-1 corporate GHG inventory (Scope 1+2+significant Scope 3), ISO 14067 cradle-to-gate product carbon footprint (verified per ISO 14071), SBTi-aligned reduction targets (50% by 2030, net-zero by 2050), CSRD/ESRS E1 disclosure support for EU customers, recycled content (recycled PP, recycled steel), renewable energy manufacturing, eco-design optimization.
