Managing Change in the Atmosphere

Carbon footprint

• \(\bullet\)The carbon footprint is the total amount of carbon dioxide and other greenhouse gases emitted over the full life cycle of a product, service or event.
• \(\bullet\)The carbon footprint can be reduced by reducing emissions of carbon dioxide and methane.
• 

Reducing the use of fossil fuels

• Use of nuclear or renewable power
• Recycling and reusing materials
• Fuel-efficient vehicles
• Reducing energy consumption in the home
• Using mass transport rather than personal vehicles
• 

Limiting the emission of harmful gases

• Stop deforestation
• Carbon capture - Capturing \(CO_2\) produced by power stations and storing it safely in geological sites such as depleted oil wells
• Use low sulfur fuels
• Use catalytic converters in vehicles to convert nitrous oxides to harmless nitrogen
• Have legal limits to exhaust emission
