Carbon Footprint Calculator – User Guide

🌍 Overview

The Carbon Footprint Calculator helps you measure your personal environmental impact by calculating how much carbon dioxide (CO₂) you produce annually. Understanding your carbon footprint is the first step toward reducing your environmental impact and living more sustainably.

🎯 How to Use the Calculator

Step 1: Home Energy Assessment

Monthly Electricity Usage (kWh)

• Enter your average monthly electricity consumption

• Typical range: 200-800 kWh for most households

• Find this on your electricity bill or utility account

Natural Gas Usage (therms/month)

• Enter your monthly natural gas consumption

• Typical range: 20-100 therms for average homes

• Check your gas bill for exact usage

Step 2: Transportation Analysis

Car Miles Driven Weekly

• Enter total miles driven per week across all vehicles

• Include commuting, errands, and personal trips

• Tip: Use your odometer or GPS tracking for accuracy

Public Transport Usage

• Select your public transportation frequency:

  • None: Never use public transport

  • Occasional: 1-2 times per week

  • Regular: 3-5 times per week

  • Daily: Use public transport daily

Flights per Year (short-haul)

• Count round-trip flights under 4 hours

• Include both business and personal travel

• Long-haul flights have higher impact but are less frequent

Step 3: Food & Shopping Habits

Diet Type

• Heavy Meat Eater: Meat with most meals

• Average Meat Eater: Meat with some meals (typical)

• Vegetarian: No meat, but dairy/eggs

• Vegan: No animal products

Food Waste Level

❓ Frequently Asked Questions

Q: How accurate is the calculator?

A: It uses standard emission factors and provides a good estimate. Individual results may vary based on specific circumstances.

Q: What’s a “good” carbon footprint?

A: The global target is 2-3 tons per person annually to combat climate change effectively.

Q: Why are flights counted separately?

A: Air travel has disproportionately high emissions per mile compared to other transport.

Q: How often should I recalculate?

A: Quarterly or when you make significant lifestyle changes.

Q: Are all emissions included?

A: This covers major personal categories. It doesn’t include embedded emissions in public services or infrastructure.
