The Climate Action Network Europe published a study April 29 that found that the European Union’s binding 2020 goals of a 20 percent cut in GHG emissions and for 20 percent of energy to be provided from renewable sources could be jeopardized by the lack of a binding energy efficiency targets and by uncertainties over enforcement. The Accountability of European Renewable Energy and Climate Policy study concluded that the renewables target if nonbinding energy efficiency measures were also established.
