Back in 2004, Stephen Pacala and Rob Socolow of Princeton University, US, came up with the concept of “stabilization wedges”, a way of mixing and matching currently available technologies to cut carbon emissions by the amount needed to stabilize the climate. The paper was a reaction to what Pacala and Socolow saw as strategy to stall action on global warming by the Bush administration by claiming that the world lacked the technology to tackle it. While any one of today’s technologies alone is unable to meet the challenge, the pair showed that a portfolio of such solutions would be up to the job.

Here Pacala speaks to environmentalresearchweb about how emissions and the planet have changed since publication of the wedges paper, the potential effects of a recession, how easy it might be to invent our way out of the problem, and his new work on calculating fair national emissions caps by assigning individual carbon allowances.
