The UK’s Committee on Climate Change (CCC) has advised its government to go zero-carbon by 2050. But, say Joe Blakey and Marc Hudson of the University of Manchester, counting all emissions means counting the carbon footprint of imports too. Including these (and excluding emissions from exports) the UK’s footprint is 70% higher than the figure used by the CCC. The same is likely true for all high income economies. And the cost of successful … [Read more...]
Carbon Capture: Can CO2-EOR really provide carbon-negative oil?
Enhanced Oil Recovery (EOR) injects CO2 into oil reservoirs, increasing the pressure and forcing the oil out. 20% of global oil production uses EOR. But if that CO2 doesn’t stay underground it hasn’t been captured. If it was itself extracted from natural underground CO2, there is no benefit – or worse. Ideally, it should come from already captured CO2. But most oil wells are nowhere near a CCUS (carbon capture, usage and storage) facility: in the … [Read more...]
