I'm resitting this exam. I've hardly revised though as I've had other exams. To be honest, the syllabus seems much larger than it is; visiting revision sites and getting the key points and definitions from the book is the most important thing, OCR sticks a lot of extra 'stuff' in the textbook you may not necessarily need.

EU agreement between countries to minimise carbon emission long term
-at least 20 percent of energy should come from renewable sources by 2020,
-at least 10% of fuels used in transport will be biofuels,
-eu green house gas emmissions will be reduced to 20% below 1990 levels,
-urther reduce greenhose gas emission to 30%,

ccs- carbon capture storage and stored in deep in oceans, in geological formations, reacts with co2 to form metal carbonate and found in exhaust fuels,
2) bioethanol, turbine, biobutanol , current
