I interviewed for a company (years ago), while I didn't get the job, I did study their business model.

In an effort to slow/prevent climate change, the Canadian Government agreed to implement a Carbon Credit exchange system. It was discovered that modifying agricultural techiniques reduced carbon emissions by using the soil as a carbon store.

Exchanging and tracking carbon credits is difficult for small farmers, so this company decided to aid in the process by acting as a middle man. They track all of the paperwork involved by paying companies for reduced emissions, and then selling the tracked reductions on to other companies.

An ecologically responsible, community minded company.

Here is the question: who profits in this model?
