Climos Def New company wants to seed ocean with iron to sequester carbon		05 Mar 2008	News
Posted at 12:24 PM on 05 Mar 2008 Weeks after ocean-seeding company Planktos bit the iron dust, a startup called Climos is plowing ahead with a similar business plan: seed the ocean with iron dust to stimulate the growth of CO2-gobbling plankton, then sell offsets for the sequestered carbon. Climos has announced $3.5 million in venture capital and is backed by reputable investors: Tesla Chair (née Pay-Pal cofounder) Elon Mu ...

Rule four of offsets: No enhanced oil recovery Injecting CO2 into oil wells is not real carbon sequestration	Joseph Romm	24 Aug 2007	Gristmill
Capturing CO2 and injecting it into a well to squeeze more oil out of the ground is not real carbon sequestration. Why? When the recovered oil is burned, it releases at least as much CO2 as was stored (and possibly much more). Therefore, CO2 used for such enhanced oil recovery (EOR) does not reduce net carbon emissions and should not be sold to the public as a carbon offset. Yet a company, Blue Source, LLC, proposes to do just that: to capture the CO2 from a f ...

Trees They're not going to save us	David Roberts	10 Aug 2007	Gristmill
Oh well, it was a nice thought: A decade-long experiment led by Duke University scientists indicates that trees provide little help in offsetting increased levels of the greenhouse gas carbon dioxide. Note to the hordes of indignant commenters lunging for the CAPS LOCK key: this does not mean trees are worthless. Trees do many wonderful things. They're like ponies and ice cream, only awesomer. I'm going to go hug one as soon as I'm done with this post. Yay for tree ...

Rule three of offsets: No geo-engineering Smacking down a bad idea	Joseph Romm	27 Jul 2007	Gristmill
I know you've all been eagerly waiting for this (don't worry, I don't have many more rules). I got sidetracked by last week's offset hearing. Offset projects should deliver climate benefits with high confidence -- that's a key reason trees make lousy offsets, especially non-urban, non-tropical trees. An even more dubious source of offsets is geo-engineering, which is 'the intentional large scale manipulation of the global environment' (PDF) to counter ...

Timber industry rent seeking Making things out of wood sequesters carbon, turns out	David Roberts	25 Jul 2007	Gristmill
One telling point that carbon tax advocates make against cap-and-trade systems is that they create an enormous incentive for rent-seeking. Now it seems the timber industry is getting in on the game. Via Greenwire (sub rqd), this has my BS alarm all a-ringin': [Timber] Industry groups are lobbying Congress and making a public relations push to promote privately managed forests as carbon sinks -- a bid for a place in potential cap-and-trade schemes for greenhouse gas e ...
