This is my second post in a series of on carbon offsetting where I compare different providers and ways of carbon offsetting for a trip from Brussels to Stockholm. The first post was about how much carbon you need to offset for a trip.
The second question comes to what type of offsetting to do. Basically there are two broad classes – the ones that are approved through the Clean Development Mechanism (CDM) in the Kyoto protocol called Certified Emissions Reductions (CERs) and ones that aren’t so called VERs (Verified Emission Reductions).

The CERs are usually big projects that have the financial and administrative resources to go through the rigourus certification process required. VERs are generally smaller projects and can be either in developing or developed countries (CDM is only for developing countries).
For the VERs there is currently no single best standard, but rather a lot of different ones. The major ones seems to be the Gold Standard (with different subcertification for developing/developed countries etc.), the Voluntary Carbon Standard and the VER+, where the first two seems to have the biggest backing.
Additionally, there is one thing to watch out for – “tree planting projects“. These projects are the most controversial as what it basically is is a long term storage of carbon that will eventually be released again. The scientific basis of these seem to be under question, so I’d just choose to stay away from them.
From the services I compared there was a range between those who said that their projects complied strictly to CDM (www.carbonpassport.com, www.clear-offset.com) to those that had an unspecified mix of projects conforming to any of the standards (www.climatecare.org, www.greenseat.com), to those who also had their own projects not conforming to any of the standards (www.carbonneutral.com, www.nativenergy.com).
For the spreadsheet I used to compare providers, you can see it here.

Hi Linus
Like what you’re doing here … just wanted to mention that the googledocs link to the spreadsheet where you compare the providers is not functioning. If you can get it working I’d really like to take a look. I have a blog looking at this world from a more ‘market oriented’ position but I like to attend to the personal side too.

Linus,
I must apologise! Looks like you’re miles ahead of me. Thanks for the plug. BTW – keep an eye out for the UK Government’s forthcoming offsetting quality standard – should be released on the 1st October or just after…

@carbontrader
I got it up now, seems that Google Docs somehow managed to break the document. Please, do give me some feedback in case I missed something.
@benjahedley
Yours was one of the services that seemed to stand up pretty well in the comparison. I read somewhere that there might be a lack of CDM accredited projects to invest and that offsetting relying on these might be hard to actually accomplish. How do you look at that?

Linus,
the market for CDMs is pretty big. There have been delays in some projects recently, but on the whole there are are enough to go around at the moment.
I think one issue recently has been the closing down the HFC production CER loophole, which happened at last, but did reduce supply a bit.
On the whole though, the market is healthy and being demand driven a reduction in supply just means prices increase for those who really need / want them…
