Clean technologies are scientific or process innovations that reduce carbon intensity and environmental pollution leaving a smaller human ecological footprint. Their applications can be used to make traditional industries (e.g. energy, mining, industrial, transport) more energy or raw material efficient. Technologies that help preserve and restore the environment will benefit from significant growth prospects.
Investments in clean technologies have grown considerably with global new investment in clean energy increasing nearly five-fold from $55 billion in 2004 to $318 billion in 2011. Cumulative investments from 2004 to 2013 have reached nearly $2 trillion.
