Shortly after our study on unused fossil fuels was published in Nature[1], Andrew Leach, an acknowledged expert in Canadian oil sands, wrote a piece scrutinising some of our conclusions. We were grateful for Andrew’s comments, which he said could be summarised as ‘plenty of good, a lot of bad, and some ugly’. (more…)

LEAVING FOSSIL FUELS IN THE GROUND: HOW MUCH, WHERE AND OVER WHAT TIME FRAME?

We have known for some time that to limit global warming, some of the world’s fossil fuel reserves are going to have to stay in the ground. All of the carbon dioxide that would result from burning current fossil fuel reserves is around three times the amount that gives us a decent chance of staying below the 2oC threshold (the temperature rise accepted by the international community as associated with the possible onset of dangerous climate change).

Until recently people therefore frequently reported that two thirds of fossil fuels globally were ‘unburnable’. While it’s possible to get lots of interesting insights from this simple finding, this treats all the fossil fuels as the same. This is too simplistic. (more…)
