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.
Carbon neutrality
Companies introduce methods, such as planting trees, to take out as much carbon dioxide as they put into the atmosphere. Overall the amount of carbon entering the atmosphere would be zero
Carbon footprint
Emissions of carbon dioxide and methane
Carbon off-setting
Plant more trees (reforestation) to convert carbon dioxide into oxygen
Capture, and store, carbon
Carbon dioxide gas from power stations can be stored underground
Increase/introduce taxes
Penalise companies/individuals for releasing too many greenhouse gases
There are many things you can do to reduce your personal carbon footprint:
use more alternative energy supplies, often referred to as 'green energy'
reduce your energy consumption, and/or increase energy efficiency, in your home
reduce your use of cars, or increase the fuel efficiency
car share or use public transport, to reduce the amount of road vehicles
