*** WHAT’S COVERED ***
1. Definition of a carbon footprint
* The total amount of carbon dioxide and other greenhouse gases emitted over the entire lifecycle of a product, service, or event.
2. Why measuring carbon footprints is difficult
* The need to account for all lifecycle stages, including sourcing raw materials, manufacturing, transport, power consumption, and disposal.
3. Methods to reduce carbon footprints and emissions
* Utilising renewable energy sources (wind, solar, nuclear).
* Implementing more efficient manufacturing processes to reduce energy and waste.
* Government interventions like new laws and taxes.
* Using carbon capture technology to store CO₂ underground.
4. Real-world challenges in reducing emissions
* The high economic cost of alternative technologies compared to fossil fuels.
* The difficulty for governments to implement changes that might harm the economy.
* The challenge of securing international agreements.
* The role of individual responsibility in making sustainable choices.
