Global warming and the water and energy crises are threatening life on Earth. As the signs of danger unravel and awareness heightens, man can no longer stem the effects of his careless stewardship of Earth by passive inaction. Clean and green environmental technologies become necessary to decelerate, if not stop, the alarming effects of Earth's decreasing sustainability. These are the main drivers for clean and green environmental technologies. This research service presents findings from technology trends in the clean and green environment sector captured from accumulated secondary and primary research. It provides a snapshot of the top technologies in the sector that are likely to impact planet Earth in 2013 and until 2020.
