1998-2014. 1 The perceived slowdown has confirmed the beliefs of climate change doubters and fueled a debate on climate science widely covered by the media. This ongoing debate is stimulated by three important considerations.The first and most obvious consideration is that not all countries and industries are equally affected by climate change. As in other policy areas, the introduction of a new regulation naturally gives rise to policy debates between the losers, who exaggerate the costs, and the winners, who emphasize the urgency of the new policy. The second consideration is that climate mitigation has typically not been a "front burner" political issue. Politicians often tend to "kick the can down the road" rather than introduce policies that are costly in the short run and risk alienating their constituencies-all the more so if there is a perception that the climate change debate is not yet fully settled and that climate change mitigation may not require urgent attention. The third consideration is that although the scientific evidence on the link between carbon dioxide (CO 2 ) emissions and the greenhouse effect is overwhelming, there is considerable uncertainty regarding the rate of increase in average temperatures over the next 20 or 30 years and the effects on climate change. There is also considerable uncertainty regarding the "tipping point" beyond which catastrophic climate dynamics are set in motion. 2 As with financial crises, the observation of growing imbalances can alert analysts to the inevitability of a crash but still leave them in the dark as to when the crisis is likely to occur.This uncertainty should be understood as an increasingly important risk factor for investors, particularly long-term investors. At a minimum, the climate science consensus tells us that the risks of a climate disaster are substantial and rising. Moreover, as further evidence of climate events linked to humancaused emissions of CO 2 accumulates and global temperatures keep rising, there is an increased likelihood of policy intervention to limit these emissions. 3 The prospect of such interventions has increased significantly following the Paris Climate Change Conference and the unanimous adoption of a new universal agreement on climate change. 4 Of course, other plausible scenarios can be envisioned whereby the Paris agreement is not followed by meaningful policies. From an investor's perspective, there is therefore a risk with respect to both climate change and the timing of climate mitigation policies. Still, overall, investors should-and some are beginning to-factor carbon risk into their investment policies. It is fair to say, however, that there is still little awareness of this risk factor among (institutional)
