How much CO₂ does your food, travel, tech, and lifestyle really produce? Dive into verified emissions data, source breakdowns, and practical tips to reduce your impact.

Use our free calculators for travel, diet, energy, and more — with country-specific data.
View all calculatorsCarbon footprints vary significantly by country due to differences in energy grids, farming practices, supply chains, and climate. For example, beef from Brazil (with deforestation-linked land use) can emit 3-5x more than European pasture-fed beef. Similarly, an electric car in France (nuclear-powered grid) produces 90% less CO₂ than one charged on a coal-heavy grid. The figures below represent global median estimates from peer-reviewed research — use our country-specific calculators for a more accurate picture.
Beef produces ~27 kg CO2e per kg — the highest of any common food. See the full emissions breakdown, country comparisons, and how to reduce your impact.
A return transatlantic flight produces ~1.6 tonnes CO2 per passenger — roughly 16% of the average annual footprint. See the full breakdown by distance and class.
One hour of video streaming produces 36-100g CO2 depending on device and resolution. See the real data on Netflix, YouTube, and gaming emissions.
An iPhone 15 Pro produces 75 kg CO2e over its lifecycle — 83% from manufacturing. See why keeping your phone longer is the best climate action.
An EV produces 40-60% fewer lifetime emissions than a petrol car in most countries. See the full lifecycle breakdown including battery manufacturing.
Working from home saves 0.5-1.7 tonnes CO2/year vs commuting by car. But home heating and electricity add back some emissions. See the full comparison.
Cement production alone accounts for 8% of global CO2. One tonne of concrete produces ~410 kg CO2. See the full breakdown and low-carbon alternatives.
Bitcoin mining consumes ~150 TWh/year — comparable to Poland. A single transaction produces ~700 kg CO2. See the full energy and emissions breakdown.
The fashion industry produces 4-8% of global emissions — more than aviation. A single cotton T-shirt generates ~8 kg CO2. See the full lifecycle breakdown.
Training GPT-4 produced ~5,000 tonnes CO2. A ChatGPT query uses 10x more energy than a Google search. See the full breakdown of AI emissions.
The average UK home produces 2.7 tonnes CO2/year from energy alone. See the full breakdown by heating, electricity, and how to cut your home emissions.
A cup of coffee produces 0.05-0.6 kg CO2 depending on preparation method. See how milk, pods, and brewing method change your coffee's carbon footprint.
Plastic production emits 1.8 billion tonnes CO2/year — 3.4% of global emissions. See the full lifecycle from oil extraction to disposal and recycling.
Solar panel production carbon footprint (~400–750 kg CO2e per typical residential panel) vs lifetime savings: 20–50g CO2/kWh. Payback 1–3 years; methodology + energy calculator links on page.
Fast fashion produces 10% of global CO2 — more than aviation and shipping combined. The average garment is worn just 7 times. See the full impact.
The internet produces 2-4% of global CO2 — comparable to aviation. Data centres, networks, and devices each play a role. See the full breakdown.
