Not really aligned with sustainable cities per se, but occasionally you read a blog that just clarifies complexity in a wonderfully concise way. Today I read a blog written by Howard J. Herzog, a Senior Research Engineer at Massachusetts Institute of Technology. In his blog on The Conversation‘s website “Pumping CO2 underground can help fight climate change. Why is it stuck in second gear?” he explains not only the opportunity afforded by carbon capture and storage but also disentangles the complexity of financial and political interventions and drivers. But, quite simply, he does make the case for capturing ‘free’ CO2 and storing it underground to reduce the amount of greenhouse gases in the atmosphere causing climate change.
On the same day, by coincidence, George Monbiot writes in The Guardian “The extraction of fossil fuels is a hard fact. The rules governments have developed to prevent their use are weak, inconsistent and negotiable. In other words, when coal, oil and gas are produced, they will be used. Continued production will overwhelm attempts to restrict consumption. Even if efforts to restrict consumption temporarily succeed, they are likely to be self-defeating. A reduction in demand when supply is unconstrained lowers the price, favouring carbon-intensive industry”. Keeping those fossil fuels that were formed over millions of years underground exactly there is the only way we’re going to stave off irreversible climate change.
Both conclude that the true cost of ‘freeing’ those carbons is not being met. If there was a true polluter pays principle it would make the case for keeping the carbon in the ground in the first place and it would certainly help invest in technologies to capture carbon, store it and re-use it. We need to find ways of keeping what is in the ground there for longer and ways of putting what has already been liberated back there, safely out of the atmosphere whilst we figure out a low carbon solution to our needs.
