1. What is a kWh to kg CO2 Calculator?

Definition: This calculator estimates the carbon dioxide (CO2) emissions produced from electrical energy consumption based on the emission factor of the electricity grid.

Purpose: It helps individuals and organizations understand and quantify their carbon footprint from electricity usage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CO_2 \) — Carbon dioxide emissions (kilograms)
• \( E_{kWh} \) — Energy consumption (kilowatt-hours)
• \( EF \) — Emission factor (kg CO2 per kWh)

Explanation: The energy consumption is multiplied by the emission factor to calculate the total CO2 emissions.

3. Importance of CO2 Emissions Calculation

Details: Understanding CO2 emissions helps in environmental impact assessment, sustainability planning, and meeting regulatory requirements.

4. Using the Calculator

Tips: Enter your energy consumption in kWh and the appropriate emission factor (default 0.233 kg/kWh for UK grid). Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is an emission factor?
A: It represents the amount of CO2 emitted per unit of electricity generated, varying by energy source and grid mix.

Q2: Why is the default 0.233 kg/kWh?
A: This is the average for the UK electricity grid. Factors vary by country (e.g., ~0.5 kg/kWh for coal-heavy grids).

Q3: How can I find my local emission factor?
A: Check with your national energy statistics agency or electricity provider for the most accurate data.

Q4: Does this include all greenhouse gases?
A: Typically just CO2, though some factors may include other gases converted to CO2 equivalents.

Q5: How accurate is this calculation?
A: It provides a good estimate, but actual emissions vary by time of day and specific generation sources.
