Question re the Carbon Tax

Hoping some of the supporters of the Carbon Tax can answer this one!
If a company pays the Carbon Tax and then takes measures to reduce their carbon footprint such as installing Solar Panels and using Toyota Prius cars for their fleet and so on, do they then get the amount of Carbon Tax that they have to pay reduced?
I am pretty sure I read that Sanatarium were doing both of those things along with other measures to reduce their environmental footprint, will they be getting a discount on the amount of Carbon Tax that they are required to pay as opposed to their competitor Kellogg's for example?
