The environment chief has brushed aside a cross-party call by lawmakers to replace the city's 'pseudo' carbon reduction target with a real one, saying only that the government might review its climate strategy. In a motion debate ahead of the world climate conference in Copenhagen next week, legislators put aside political differences, calling for replacement of the 'energy intensity' target with an absolute carbon reduction target. They also called on the government to look at ways to help developing countries finance reductions. Environment Secretary Edward Yau Tang-wah, who will join the Chinese delegation in Copenhagen, said the government might review its strategy in light of the new targets set by the mainland. Beijing says it will try to reduce carbon intensity - carbon emissions per unit of gross domestic product - by 40 to 45 per cent below 2005 levels by 2020. This differs from Hong Kong's target of a 25 per cent cut in energy intensity - the amount of energy used per unit of GDP - below the 2005 level by 2030, under a regional agreement. Audrey Eu Yuet-mee, the Civic Party legislator who moved the motion, was unhappy at what she called a lack of commitment. 'It is totally disappointing because we all know that the current energy intensity target is just a pseudo target,' she said.
