«As a society, we need to better understand the potential cost and performance of CDR strategies for the same reason that we need to better understand the cost and
performance of emission mitigation strategies — they may be important parts of a portfolio of options to stabilize and reduce atmospheric concentrations of carbon dioxide»
In 2014, these organizations decided to join forces and provide more comprehensive guidance including a method that illustrates the
scale of emissions mitigation required to achieve a 2 °C pathway and the differences facing each sector to achieve reductions.
Second, both sets of intervention also bring some similar ethical risks, such as potential for certain forms of «moral hazard»: the likelihood that
rates of emissions mitigation will be lower than otherwise, in the belief that SRM or CDR can rectify the «overshoot» at some future date.
