ESS, a company that sells software for managing corporate information related to various compliance initiatives, has teamed up with Carbonetworks to help companies track greenhouse emissions information more formally.
Carbonetworks' Carbon Balance Sheet actually turns a company's greenhouse information into something that can be expressed as a financial value. Basically, carbon assets minus liabilities equals what the company calls the "carbon balance." The deal between the two software suppliers will allow companies to aggregate the information across an entire organization rather than just looking at projects separately. The idea is that it will help businesses prioritize.
Regardless, if your company already uses some sort of software to manage environmental, health and safety regulations, it might be worth adding information about the greenhouse effect.
