"CCS" often refers to carbon capture at power stations (where CO2 comes out at high concentrations). MacKay's<br />"The last thing we should talk about" is <b>Capturing carbon dioxide <em>from thin air</em>,</b><br />which is a more costly and difficult thing to do because the CO2 is at such low concentrations.
