According to this report, the greatest efficiency gains have been led by policy and the greatest untapped potential lie where policy is absent or inadequate. It focuses on progress made in China. The report demonstrates the central role of policy in driving energy efficiency. According to the report, the largest global gains in energy efficiency are linked to mandatory policy instruments such as minimum energy performance standards (MEPS). While the expansion of policies has been effective in generating energy savings and reducing emissions, more is required and more is possible, according to the authors. And, improvements in energy intensity and energy efficiency are still far from achieving our climate goals. Analysis presented in the report emphasizes that policies must be strengthened and their coverage expanded to boost the potential of energy efficiency.
