Exam points

  • Separate responses that reduce emissions from adaptation measures that limit climate impacts.
  • Weigh biofuel and reforestation benefits against food production, land demand and long-term effects.
  • Assess country climate plans by linking energy choices and sector emissions to stated targets.
  • Compare societal adaptation through flood protection, freshwater supply and climate-resilient crops.
