Understanding Your Carbon Footprint
Your carbon footprint is the total greenhouse gas emissions caused by your activities, measured in tonnes of CO₂ equivalent per year. The main contributors are transportation (especially flying and driving), home energy (heating and electricity), diet (meat production is carbon-intensive), and consumption of goods. Even small changes — like reducing one long-haul flight or switching to a plant-based diet two days a week — can significantly reduce your footprint.
