As South Korea's economy has grown remarkably over the last decade, so have its carbon emissions. In fact, Seoul has the second highest emissions growth rate in the world.
Such an increase would be even higher if it were not for the country's 20 nuclear reactors, which generated a little more than one-third of the country's total electricity in 2008. According to that year's National Energy Basic Plan, South Korea wants to increase nuclear energy's share of domestic electricity generation to 59 percent by 2030. To do so, it will need to build roughly 18 more nuclear reactors.
