Carbon Accounting and Emissions Reporting

Scope 1, 2, 3 Emissions Framework

Defining Emission Scopes:

GHG Protocol Scopes (International Standard):

Scope 1 - Direct Emissions (From company operations):
✓ Controlled combustion sources
  - Owned/leased facilities (natural gas heating)
  - Company vehicles (fleet)
  - Manufacturing equipment
  - Process emissions (chemical reactions)
✓ Examples:
  - Natural gas in owned office building
  - Company fleet gasoline consumption
  - Manufacturing facility furnace emissions
  - Chemical plant process emissions

✓ Relatively Easy to Measure
  - Meters/fuel receipts available
  - Direct control over source
  - Can take immediate action

Scope 2 - Indirect Emissions (From purchased electricity):
✓ Purchased electricity for company operations
✓ Purchased steam/heat
✓ Purchased cooling
✓ Examples:
  - Electricity for office building
  - Electricity for manufacturing
  - District heating steam
  - District cooling systems

✓ Calculation Method:
  - Electricity (kWh) × Grid emission factor (CO2/kWh)
  - Grid factor varies by region (coal-heavy vs. renewable)
  - Example: Texas grid ~0.4 metric tons CO2/MWh
            California grid ~0.2 metric tons CO2/MWh
            Coal-heavy region ~0.7 metric tons CO2/MWh

✓ Two Accounting Methods:
  - Location-based: Uses average grid emission factor
  - Market-based: Uses actual renewable energy purchased
  
  Example (1,000 MWh purchased):
  Location-based (regional avg): 1,000 MWh × 0.4 = 400 mtCO2e
  Market-based (100% renewables purchased): 1,000 MWh × ~0 = ~0 mtCO2e
  Difference: 400 mtCO2e (by using renewables)

Scope 3 - Indirect Emissions (From value chain):
✓ Most Complex and Challenging
✓ Most Material for Many Companies
✓ Often Larger than Scope 1 + 2 Combined

Categories (15 total, many companies track 5-10 primary):

Upstream (Before company operations):
1. Purchased goods & services (supplier emissions)
   - Manufacturing of purchased materials
   - Transportation of purchased goods
   - Office supplies production
   - Example: Steel production for manufacturing

2. Capital goods (equipment/facilities)
   - Production of purchased equipment
   - Construction of facilities
   - IT infrastructure production

3. Fuel & energy-related activities
   - Not included in Scope 1 or 2
   - Extraction/production of fuels
   - Example: Methane from natural gas extraction

4. Upstream transportation
   - Third-party transportation of inputs
   - Example: Supplier delivery to company

5. Waste disposal
   - Emissions from waste handling
   - Landfill methane from company waste

6. Business travel
   - Flights, hotels, rental cars
   - Example: Employee flight to client site

7. Employee commuting
   - Employee drives to office
   - Not all companies include (optional)

Downstream (After company operations):
8. Downstream transportation
   - Third-party transport of products to customer

9. Product use
   - Emissions from customer using product
   - Example: Gas consumption in sold vehicles

10. End-of-life treatment
    - Emissions from product disposal
    - Recycling processes

Key Differences Among Scopes:

| Aspect | Scope 1 | Scope 2 | Scope 3 |
|--------|---------|---------|---------|
| Control | High | Medium | Low |
| Measurement | Easy | Moderate | Difficult |
| % of Total | 10-30% | 5-20% | 50-90%* |
| Action Speed | Fast | Moderate | Slow |
| Cost | Moderate | Low | Variable |

*Varies significantly by industry
  Scope 3 very large for: Retail, Fashion, Tech, Consumer goods
  Scope 3 manageable for: Utilities, Energy, Manufacturing

Calculating Emissions:

Emissions = Activity Data × Emission Factor

Example Calculations:

Scope 1 - Owned Facility Natural Gas:
- Monthly usage: 5,000 therms
- Emission factor: 5.3 kg CO2e per therm
- Monthly emissions: 5,000 × 5.3 = 26,500 kg CO2e = 26.5 mtCO2e
- Annual emissions: 26.5 × 12 = 318 mtCO2e

Scope 1 - Company Fleet Vehicles:
- Fleet size: 50 vehicles
- Average annual miles: 12,000 miles/vehicle
- Total miles: 50 × 12,000 = 600,000 miles
- Emission factor: 0.41 kg CO2/mile (average sedan)
- Annual emissions: 600,000 × 0.41 = 246,000 kg CO2e = 246 mtCO2e

Scope 2 - Office Building Electricity:
- Annual consumption: 500,000 kWh
- Grid emission factor: 0.4 mtCO2e/MWh (Texas grid example)
- Annual emissions: 500 MWh × 0.4 = 200 mtCO2e

Scope 3 - Business Travel (Air):
- Annual flights: 150
- Average flight: 2,500 miles
- Total miles: 150 × 2,500 = 375,000 miles
- Emission factor: 0.255 kg CO2/mile (economy)
- Annual emissions: 375,000 × 0.255 = 95,625 kg CO2e = 95.6 mtCO2e

Scope 3 - Purchased Goods (Materials):
- Annual material cost: $50M
- Emission intensity: 1.2 kg CO2e/$
- Annual emissions: $50M × 1.2 = 60,000 mtCO2e
(Complex due to material variation - often estimated by $ spending)

Company-Wide Emissions Inventory (Example):

Scope 1:
- Natural gas (facilities): 318 mtCO2e
- Fleet vehicles: 246 mtCO2e
- Process emissions: 450 mtCO2e
- Subtotal: 1,014 mtCO2e

Scope 2:
- Purchased electricity: 200 mtCO2e (location-based)
- Purchased steam: 50 mtCO2e
- Subtotal: 250 mtCO2e

Scope 3 (Major Categories):
- Business travel (air): 95.6 mtCO2e
- Employee commuting: 340 mtCO2e (optional)
- Purchased goods: 60,000 mtCO2e
- Waste disposal: 120 mtCO2e
- Downstream transportation: 3,500 mtCO2e
- Subtotal: 64,055.6 mtCO2e

**Total Emissions: ~65,320 mtCO2e annually**

Breakdown by scope:
- Scope 1: 1.5%
- Scope 2: 0.4%
- Scope 3: 98.1%

Key Insight: Scope 3 dominates (typical for most companies)
Primary lever for carbon reduction: Manage supplier emissions

- 2027-2028: Audit/assurance becomes standard

Net-Zero Commitments and Targets

Science-Based Targets

Understanding Net-Zero Commitments:

Net-Zero Terminology:

Carbon Neutral ≠ Net-Zero:
- Carbon neutral: Emissions = Offsets
  (Company emits 100 mtCO2e, buys 100 mtCO2e offsets = carbon neutral)
- Net-zero: Actual emissions reduced 90%+, remaining 10% offset
  (Company reduces to 10 mtCO2e, offsets 10 = net-zero)
- Net-zero is more rigorous

Science-Based Targets (SBTi):

Definition: Emissions reduction targets aligned with climate science
- What emissions level is required for 1.5°C warming limit?
- Company must reduce proportionally
- Verified against scientific climate models

SBTi Process:
1. Establish baseline (historical emissions, usually 2020)
2. Calculate target (% reduction needed by 2030, 2050)
3. Develop pathway (interim milestones, actions)
4. Verify with SBTi (third-party scientific review)
5. Disclose & monitor

Example Science-Based Target:

Company baseline (2020):
- Scope 1 & 2: 50,000 mtCO2e
- Scope 3: 500,000 mtCO2e
- Total: 550,000 mtCO2e

Net-zero science-based target by 2050:
- Near-term by 2030: 45% absolute reduction
  - 2030 target: 550,000 × 55% = 302,500 mtCO2e
  - From 2020 baseline, reduce 247,500 mtCO2e (45%)

- Mid-term by 2040: 75% reduction
  - 2040 target: 137,500 mtCO2e

- Long-term by 2050: 90% reduction
  - 2050 target: 55,000 mtCO2e (offset remaining)

Pathway to Target (Actions):

Energy efficiency (25% of reduction):
- Facility retrofits: 61,875 mtCO2e reduction
- Equipment upgrades: Industrial efficiency

Renewable energy (40% of reduction):
- 100% renewable electricity by 2030: 99,000 mtCO2e
- Covers Scope 2 primarily

Supply chain optimization (20% of reduction):
- Supplier engagement: 49,500 mtCO2e
- Material substitution: Lower-carbon alternatives
- Transportation optimization: Mode shifts

Carbon removal (10% of reduction):
- Remaining 27,500 mtCO2e after 90% reduction
- Direct air capture technology (future)
- Reforestation/nature-based solutions

Interim Milestones & Accountability:

2025: 10% reduction (55,000 mtCO2e)
- Facilities retrofits: 20%+ complete
- Renewable contracts: 40% signed

2027: 25% reduction (412,500 mtCO2e)
- Facilities: 60% complete
- Renewable energy: 70% mix
- Supplier engagement: Initial 50+ suppliers

2030: 45% reduction (302,500 mtCO2e)
- Facilities: 100% complete
- Renewable energy: 100% mix (for electricity)
- Supplier targets: Active in 200+ suppliers
- Executive compensation: 20% tied to climate targets

Verification & Monitoring:
- Annual emissions inventory (third-party spot-checked)
- Progress against 2030 target (disclosed annually)
- Public accountability (regulatory filings, annual report)
- Penalty risk: If missing targets substantially, shareholder litigation possible

Implementation and Challenges:

Common Challenges in Net-Zero Implementation:

Challenge 1: Scope 3 Dependency (Supply Chain)
- Problem: Scope 3 often 70-90% of total emissions
- Company has limited direct control
- Requires supplier engagement (difficult, complex)
- Solution:
  ✓ Develop supplier engagement program
  ✓ Set expectations in contracts
  ✓ Provide technical support for supplier transitions
  ✓ Use leverage: Large companies can influence suppliers
  ✓ Example: Walmart requires suppliers to reduce emissions
            (access to distribution network as incentive)

Challenge 2: Capital Requirements
- Problem: Transition requires significant capex
  - Building retrofits: $500-1,000/square foot
  - Renewable energy installation: $1-3M per MW
  - Supply chain transformation: 5-10 year horizon
  
- Example capital spend (100,000 sq ft facility):
  - Building efficiency: $50-100M
  - Solar installation (3MW): $3-9M
  - EV fleet conversion (500 vehicles): $10-15M
  - Supplier development: $5-10M
  - Total: $75-150M over 5-10 years
  
- Solution:
  ✓ Phased approach (prioritize highest ROI first)
  ✓ Use green financing (lower rates)
  ✓ Demonstrate payback (efficiency = cost reduction)

Challenge 3: Technology Gaps
- Problem: Emerging tech needed for full decarbonization
  - Green hydrogen (not yet cost-competitive)
  - Direct air capture (pilot stage)
  - Low-carbon concrete/steel (early market)
  - Battery technology (improving but cost/capacity gaps)
  
- Solution:
  ✓ Plan for graduated technology adoption
  ✓ Invest in R&D partnerships
  ✓ Don't wait for perfect solutions (act now, improve over time)

Challenge 4: Supply Chain Complexity
- Problem: Indirect Scope 3 difficult to measure/influence
  - Supplier data availability: 30-50% of suppliers have emissions data
  - Data quality: Estimates vs. actual measurements
  - International suppliers: Multiple regulations, standards
  
- Solution:
  ✓ Develop supplier emissions questionnaires
  ✓ Phased data collection (high-value suppliers first)
  ✓ Use industry averages where data unavailable
  ✓ Invest in supplier capacity building

Challenge 5: Stranded Assets & Transition Risk
- Problem: Existing assets may become uneconomic
  - Natural gas facilities (shifting to renewable/electric)
  - Fossil fuel supply contracts (long-term commitments)
  - Equipment with 10-20 year lifespans (may not depreciate fully)
  
- Solution:
  ✓ Accelerated depreciation (write down faster)
  ✓ Asset lifecycle planning (replacements align with targets)
  ✓ Financial hedging (offset transition costs)
  ✓ Business model innovation (shift revenue sources)

Challenge 6: Measurement & Verification
- Problem: Scope 3 emissions notoriously difficult to measure
  - Suppliers: May not have data or be unwilling to share
  - Carriers: Transportation emissions complex to allocate
  - Product use phase: Depends on customer behavior
  
- Solution:
  ✓ Use standardized methods (GHG Protocol guidelines)
  ✓ Third-party verification/audits
  ✓ Transparency on assumptions & limitations
  ✓ Continuous improvement as data improves

Sector-Specific Pathways:

Energy Sector (Oil & Gas, Utilities):
- Scope 1 & 2 management: Primary (operations-focused)
- Stranded assets: Major risk
- Transition: Move to renewables/solar/wind
- Timeframe: 20-30 years (long asset lives)

Manufacturing:
- Scope 1 & 2: 30-40% of total (facility operations)
- Scope 3: 60-70% (supply chain, product use)
- Transition: Energy efficiency + renewable power + supply chain
- Capital intensive: Facility upgrades, equipment
- Timeframe: 15-25 years

Retail & Fashion:
- Scope 3: 80-95% of total (supply chain, product use)
- Supply chain: Primary lever (manufacturing in Asia, etc.)
- Transition: Supplier engagement, material substitution
- Capital: Moderate (not facility-heavy)
- Timeframe: 20-30 years (supply chain transformation slow)

Tech & Software:
- Scope 2 & 3: Primary (electricity, business travel, servers)
- Scope 1: Minimal
- Transition: Renewable power, supply chain optimization
- Asset write-downs: Minimal
- Timeframe: Shortest (10-20 years possible)
- Achievedness: Many tech companies ahead of timeline

Regulatory Compliance Risks

Enforcement and Penalties

Current and Emerging Risk:

SEC Enforcement (Climate Disclosure):

Current Authority:
- False/misleading statements if misrepresent climate impact
- Omission of material climate information (if it affects finances)
- Recent SEC enforcement:
  * Tesla: $15M SEC fine (2020) for Elon Musk tweets
  * Not climate-specific, but demonstrates enforcement willingness
  * Climate greenwashing enforcement expected to accelerate

Future Authority (Post-SEC Climate Rule):
- Non-compliant climate disclosures (if rules finalized)
- Scope 1 & 2 emissions false/misleading
- Scope 3 false/misleading (if reported)
- Transition plan omissions
- Penalty estimates: $5-50M for large companies (not finalized)

Risks:
- Misstatement of emissions: "Emissions actually 50% higher than reported"
- Misrepresentation of targets: "2030 target unrealistic/unachievable"
- Incomplete disclosure: "Omitted material climate risks"
- Inadequate governance: "Board not actually overseeing"

Recent Trends:
- SEC more active in climate enforcement
- 2024-2026: Expect increased enforcement actions
- Focus areas: Energy, utilities, financials (highest exposure)

Attorney General Enforcement (State):

California:
- Climate Corporate Data Accountability Act (2024)
  * Large companies ($1B+ revenue) must disclose Scope 1, 2, 3
  * Inaccuracy penalties: Up to $20K/day per violation
  * First major state law with enforcement teeth

- California Attorney General enforcement authority
  * Can sue companies for false climate claims
  * Penalties available
  * Precedent: ~$10-30M settlements typical for financial misstatement

Example (Hypothetical):
- Company reports Scope 3 as 50,000 mtCO2e
- Investigation finds actual: 150,000 mtCO2e
- Understatement: 100,000 mtCO2e (67% error)
- Potential penalty: If 3-year period, 1,000+ days of violation
  * $20K × 1,000 days = $20M penalty
- Risk: Class action shareholder litigation simultaneously

New York, Massachusetts, Other States:
- Climate accountability laws pending
- Likely similar structure to California
- Expect 5+ states with similar rules by 2026

Shareholder Litigation:

Securities Class Action Risk:
- Misrepresentation/omission of climate risk
- Material impact on shareholder value
- Class action if stock drop >10-20%
- Recent trends: Growing climate-focused shareholder litigation

Examples:
- Exxon Mobil shareholder suit: 2023 (settled, climate risk disclosure focus)
- BP shareholder suit: 2023 (met 2025 emissions reduction target challenges)
- Shell shareholder suit: 2023 (energy transition speed questions)
- Settlements: $20-100M+ range (material)

Credibility Risk:
- Missing ESG targets publicly disclosed: Shareholder litigation likely
- Aggressive net-zero claims not aligned with capex: Litigation risk
- Solution: Conservative targets, transparent roadmap

Reputational & Business Risks:

Supply Chain Disruption:
- Customers increasingly require supplier ESG
- Non-compliant suppliers: Delisting risk
- Example: Apple required suppliers to achieve 100% renewable
  * Suppliers unable to comply: Removed from supply chain
  * Business impact: Significant

Customer Pressure:
- Younger demographic (Gen Z, millennials) prefer sustainable brands
- Service cancellation risk: For non-compliant companies
- Example: Banks divesting fossil fuel exposure (customer demand)

Financing Risks:
- Lenders increasingly price climate risk
- Non-compliant companies: Higher borrowing costs
- Green financing: Lower rates for ESG signatories
- Cost differential: 0.5-2% interest rate variation possible

Insurance Risks:
- Directors & Officers (D&O) insurance: Climate litigation exclusions emerging
- Environmental liability insurance: More expensive for non-compliant
- Annual cost increase: 10-50% typical for exposed companies

Political/Regulatory Risks:
- Enhanced regulations: Increasingly likely 2024-2030
- Compliance cost increases: Need budget for future obligations
- Competitive disadvantage: If competitors move faster to compliance
