Computes Scope 2 greenhouse gas (GHG) emission reductions achieved by clean renewable energy generation or efficiency improvements based on regional grid emission factors (e.g. 715 g CO2/kWh for India, 385 g/kWh for US, 230 g/kWh for EU). Calculates lifetime carbon credits value and tree absorption equivalents.
Governing Formulas & Standards
Standards Basis: GHG Protocol Scope 2 / IPCC / CEA India Baseline Database
\text{CO}_2 \text{ Avoided (t)} = \frac{E_{gen} (\text{MWh}) \cdot EF_{grid} (\text{kg CO}_2/\text{MWh})}{1000}
Calculates metric tons of carbon dioxide avoided by multiplying clean MWh generation by the regional grid carbon intensity factor.
Worked Engineering Example: Annual Carbon Offset for 2.5 GWh Clean Solar Plant in India
- Annual CO2 Avoided: CO2 = (2500 × 715) / 1000 → 1,787.5 Metric Tons CO2 / year
- Tree Absorption Equivalent: Trees = (1787.5 × 1000) / 21.8 kg → 82,000 Trees Equivalent
- Carbon Credit Valuation: Value = 1787.5 × ₹950 → ₹16.98 Lakhs / year ($19.6k/yr)
Final Solution: Annual CO2 Avoided: 1,788 Tons | Tree Equivalent: 82,000 Trees | Carbon Credit Value: ₹17 Lakhs/yr
Frequently Asked Questions
- What is the difference between Scope 1, Scope 2, and Scope 3 emissions?
- Scope 1 covers direct emissions from owned sources (e.g. diesel generators, company vehicles). Scope 2 covers indirect emissions from purchased electricity/heating. Scope 3 covers all other upstream and downstream supply chain emissions.
