- Improving air quality and reducing pollution
- Reducing pollution from power stations
- Use less electricity to reduce the amound of CO2.
- Turn down the heating at home
- Insulating the home
- Turning off lights and appliances when they're not needed to be on
- Using a microwave instead of using an electric oven.
- We can remove most of the sulfur dioxide from natural gas and fuel oil.
- Less sulfur dioxide is produced.
- Wet scrubbing (removing the sulfur dioxide from the flue gases before they get out of the chimney)
- Spraying the flue gases with sea water. The sulfur dioxide is dissolved, producing carbon dioxide, water and dissolved sulfate.
- Powdered lime (calcium oxide) dissolved in water can be sprayed so the sulfur dioxide reacts and forms a solid waste product of calcium sulfate.
- Use less electricity to reduce the amound of CO2.
- Reducing pollution from vehicles
- Burning less fuel by producing more efficient engines.
- Catalytic converters are installed in all cars.
- These convert the very harmful pollutants like nitrogen monoxide to nitrogen and oxygen.
- Legal limit to how much pollution the car can produce. (Tested by MOT.)
- Using public transport
- Using different fuels
- Biofuels - renewable energy resource made from plants and waste. Only produce carbon dioxide and water. Carbon neutral as the plants needed to make it take in as much CO2 as is being released. However a lot of land needs to be cleared to grow the plants, so there is loss of habitats and biodiversity.
- Electric cars. Produce no exhaust gases and just get plugged into the mains to recharge. However, fuels are still being burnt to produce the electricity.
- Laws have been introduced to reduce the amount of pollution in the air
- Reducing pollution from power stations
