The full life-cycle footprint
The full life-cycle footprint

A carbon footprint is the total amount of carbon dioxide and other greenhouse gases released over the full life cycle of a product, service or event. Greenhouse gases absorb infrared radiation emitted by Earth and transfer energy to the atmosphere, causing warming.
Step-by-step lessons covering AQA GCSE Chemistry 9.2.4 The carbon footprint and its reduction for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
