Answer a few questions to estimate your yearly carbon footprint. Results are approximate and for guidance only. Knowing your footprint is the first step towards reducing your impact on the planet.
Your carbon footprint measures the greenhouse gases emitted through your daily activities. Major sources include:
Use this estimate as a starting point to reduce emissions by driving less, flying less often, improving insulation and choosing renewable energy suppliers. Small changes add up to make a big difference.
Understanding Your Carbon Footprint
A carbon footprint represents the total amount of greenhouse gases (primarily carbon dioxide, methane, and nitrous oxide) that are directly or indirectly produced by your activities. These gases trap heat in the atmosphere, contributing to climate change and global warming.
Major Sources of Personal Emissions
Transportation (typically 30-40% of personal footprint):
- Private vehicle use - the largest contributor for most people
- Air travel - particularly long-haul flights
- Public transport - generally much lower per passenger
Home Energy (typically 20-30% of personal footprint):
- Heating and cooling systems
- Electricity consumption for appliances and lighting
- Water heating
Food and Consumption (typically 20-30% of personal footprint):
- Diet choices - meat and dairy have higher emissions
- Food waste and packaging
- Purchased goods and services
Practical Steps to Reduce Your Carbon Footprint
Transportation:
- Walk, cycle, or use public transport for short journeys
- Consider carpooling or ride-sharing for longer trips
- Choose fuel-efficient vehicles or electric alternatives
- Reduce air travel and consider video conferencing for business
Home Energy:
- Improve home insulation and seal drafts
- Use energy-efficient appliances and LED lighting
- Set thermostats to optimal temperatures (18-20°C in winter)
- Switch to renewable energy suppliers
Lifestyle Choices:
- Reduce meat consumption and choose local, seasonal foods
- Minimise food waste through better meal planning
- Buy fewer, higher-quality items that last longer
- Repair and reuse items instead of replacing them
Remember that individual actions, while important, must be combined with systemic changes to achieve meaningful climate impact. Consider supporting policies and businesses that prioritise environmental sustainability.
How Your Score is Calculated
Our estimator uses standardized emission factors to provide your results:
- Driving: We assume an average of 0.411 kg CO₂ per mile driven.
- Flying: We estimate 0.25 tonnes of CO₂ per short-haul flight.
- Home Energy: We use an average of 50 kg CO₂ per square metre of living space per year.
Top 5 Ways to Lower Your Carbon Footprint
- Switch to Renewables: Choose a green energy provider for your home.
- Reduce Meat Intake: Eating more plant-based meals significantly lowers food-related emissions.
- Improve Insulation: Sealing drafts and adding insulation reduces the energy needed for heating.
- Fly Less: Consider trains for shorter distances or combine trips to reduce air travel.
- Drive Efficiently: Maintain correct tyre pressure and avoid carrying unnecessary weight in your car.
Frequently Asked Questions
Q: What is a "tonnes CO₂e"?
A: It stands for Carbon Dioxide Equivalent. This measures the impact of all greenhouse gases (like methane) in terms of the amount of CO₂ that would create the same warming effect.
Q: Is 10 tonnes a high score?
A: In the UK, the average personal carbon footprint is roughly 6 to 10 tonnes per year, depending on the study. The global average is closer to 4 tonnes.
