(b)(ii) Discuss whether it is feasible to reduce the carbon dioxide emissions by international cooperation according to the situations in countries P, Q and R shown in Figure 5b. (4 marks)

​Feasible

​- Country P is successful in cutting CO2 emission by replacing .... with .....

​- Thus, country P can help other countries, e.g. country Q by transferring ... of renewable energy.

​- Country P can also help by trading ..... to countries with an increase in CO2 emission, e.g. country .....

​- Since country P is a .... developed country with a high ..... (evidence). She can also help LDCs, e.g. country ... by providing c..... to help them improve their technology and energy efficiency in power generation. Through international cooperation, the use of fossil fuel in power generation can be reduced and thus, reduce CO2 emission.

​- However, it may be quite difficult for country Q to accept the transfer technology as they have a large reserve of ...... .

​- She will prefer using oil as the major energy resource because it is cheaper.
