Exclusive video: Impact of CO2 on power prices

Power risk managers may face previously unforeseen cost challenges in the next few years, as not enough research has been done to quantify the marginal effects carbon dioxide (CO2) emissions prices will have on the electricity generation sector, says expert

"My basic thesis is that not enough has been done to quantify the effects of environmental policy," said Ted Kury, director of energy studies at the University of Florida, at the Energy Risk USA conference held in Houston this month.

"There's been a trade-off between global emissions and what the carbon price is, and I don't think enough is known about the nature of that relationship. A lot of the modelling I have seen assumes a very linear relationship, where if prices go down, then emissions
