Chemistry: Cambridge International GCSE Supplement, topic 10.3.4
Strategies to Reduce Pollution Effects on Air Quality & Climate
Combat climate change by planting trees, cutting fossil fuels, and boosting renewables. Reduce acid rain with catalytic converters, low-sulfur fuels, and flue gas desulphurisation.
Reducing climate change effects
- Reducing livestock farming lowers methane emissions, a harmful greenhouse gas.
- Decreasing fossil fuels use cuts carbon dioxide released into the air.
- Increasing hydrogen and renewable energy like wind and solar provides clean power.
How trees help climate change
- Trees take in carbon dioxide during photosynthesis.
- Planting more trees means more carbon dioxide is removed from the atmosphere, reducing greenhouse gases.
Cleaner energy sources
- Fossil fuels, like coal and oil, burn to release carbon dioxide.
- Hydrogen burns cleanly, producing only water.
- Wind and solar power create electricity without pollution.
Reducing acid rain effects
- Catalytic converters in vehicles reduce nitrogen oxides and carbon monoxide.
- Using low-sulfur fuels lowers sulfur dioxide emissions from burning fuels.
- Flue gas desulphurisation with calcium oxide removes sulfur dioxide from power station emissions.
Flue gas desulphurisation and catalytic converters
- Flue gas desulphurisation treats smoke from factories to remove sulfur dioxide.
- Calcium oxide reacts with sulfur dioxide to form harmless compounds.
