Japan's draft proposal for a carbon emission reduction target sparked calls for deeper cuts from experts as well as from within the ruling coalition, as the world's fifth-biggest carbon emitter struggles to reduce its dependence on fossil fuels. The government last month presented a draft plan to aim for a 60% cut in greenhouse gas emissions by 2035 from 2013 levels, a commitment that would align with Japan's future energy mix currently under consideration and other energy policies. Climate activists have branded the proposed target as insufficient, saying that it falls short of a target set by the United Nations' main scientific body as necessary to limit global warming to 1.5 degrees Celsius above pre-industrial levels.
