A new analysis of the relationship between new green technologies and CO2 emissions in 15 EU countries shows that environmental innovations lead to decreased emissions in the long-term. The opposite is true in the short-term, however, due to the 'rebound effect': as energy efficiencies are made available, people consume more. To avoid this behavioural response, the study suggests that policy should promote both innovation and energy-efficient lifestyles. Click here to read more
