Carbon emission trading is supposed to use market mechanisms to make carbon-intense processes less attractive. Unfortunately, the EU market is flooded with emission certificates, such that the mechanism does not work.

Obviously, it would be most ecologic to leave the coal where it is. But since this does not happen, instead of buying emission certificates, it may be more effective to buy and store/sink coal to cut emissions and drive up the price.

My question is, what good ways are there store/sink coal? Just sinking large quantities of coal in the oceans is probably be a bad idea, and can have disastrous side effects. So what is known in this direction?

  • Do you mean coal? – LShaver Dec 5 at 16:32
  • It may be a language issue. I mean fossile coal that is produced from exploiting natural deposits – Rainer Glüge Dec 5 at 19:13
  • Could you get carbon credits by leaving coal in the ground ? – blacksmith37 Dec 6 at 0:57
  • Charcoal is the stuff you get by charring wood. Still, the best solution would be to never produce/dig up the stuff, since the production/mining already leads to carbon emissions. All CCS-technology currently comes down to "put it in the ground". So... leave it, where it is. – Erik Dec 6 at 9:34
