For example, Feijoo et al. [10] measured the energy efficiency of industries in Spain and concluded that energy policy and regulation reduced CO2 emissions.
The company estimates it has reduced CO2 emissions by 2,700 tonnes and saved clients £2m.
This has reduced CO2 emissions by 240,000 metric tons over the past five years.
He says "We have improved fuel efficiency by 30% and reduced CO2 emissions by 30% in recent tests".
Environmental performance proved most statistically significant: reduction in packaging, increased investment in alternative energy, reduced CO2 emissions, and reduced water waste.
All of the wind turbines, rooftop solar panels, hydroelectric and biogas plants have not reduced CO2 emissions in Europe by a single gram.
The certification process confirmed that the GNM reduced CO2 by 4,422 tonnes or 28% over the last three financial years ending March 2010.
One victor, a team in New Mexico, reconfigured energy flows, which reduced CO2 emissions in a central utilities building by 27,000 tons per year.
He says renewables offer a number of advantages over diesel for islands, including "lower costs, lower volatility of costs, reduced CO2 emissions, greater energy security and equal or improved reliability".
One exception were the CAFE standards on car fuel efficiency issued in 2011 where the benefits of reduced CO2 were significant, but still secondary to the benefits of reduced petrol consumption.By contrast, reduced CO2 is front and center in both the purpose and accounting of the EPA's new carbon pollution proposal for power plants.
