Pearson Edexcel IAL Chemistry AS 4.15 Alternative fuels & emissions
Practise evaluating alternative fuels and transport choices using renewability, CO2 emissions and climate-change arguments.
How this is tested
- justify bioethanol as renewable while noting land or food-crop disadvantages when asked
- compare electric cars or hydrogen with alkane fuels using local CO2 and pollutant emissions
- explain fossil-fuel climate impact by linking released CO2 to increased greenhouse warming
