CO 2 is today at the center of the attention of scientists and technologists for its potential as a
source of carbon. The actual utilization of CO 2 although significant “per se”(ca. 200 Mt/y)
represents a minor fraction of the anthropogenic emission (32,000 Mt/y). This chapter
describes old and new uses of carbon dioxide in synthetic chemistry, with an analysis of the
potential of several applications, highlighting barriers to a large-scale conversion and
identifying technologies, which enable the conversion into fuels. Cycling large volumes of …
