The price really depends on the project selected and can vary from less than a dollar to close to $20 per tonne, and the cheaper projects do not necessarily have less of an impact (more likely they have fewer levels of independent verification).
Do note that apart from the company recommended on the Wikimania wiki, there are other options out there. For example, on the UNFCCC portal you will find many in even under the $1/tonne range: https://offset.climateneutralnow.org/allprojects if you check the individual projects, there is quite a lot of detail and documentation included to be able to have confidence that the money goes to the correct place. The ones that come with further certification can cost more of course, with the projects on the Gold Standard website being on the $10-15/tonne price range (they have a "basket" of projects option at $11[1]), and Terrapass chosen by the organisers of Wikmania also seem to be around the $9 mark (they count in pounds for some reason on their website). For personal offsetting I am quite happy to go by the UN site and I think that is a good start to starting offsetting if one did not do it before. If one has more resources or time, they can spend it on selecting projects that meet their specific criteria (for example, social impacts beyond climate impacts, projects in specific geographic regions, or an extra level of certification) taking into account the extra cost.
