Botswana is an African nation where over 23% of population is infected with HIV. The government introduced prevention, treatment and testing strategy to address this serious issue. The goal of this program is to bring HIV infections under control in the country and reduce the chances of further infections.
According to the ‘treat all’ program every person who is tested to be <em>HIV positive</em> is given immediate treatment. All infected persons are given free Anti Retroviral Treatment for a lifetime. The government’s active measures could successfully reduce the infections that spread from affected mother to infants.

The purpose of a carbon tax is to internalise this externality. What this means is that the final price of the good should include the external costs and not just the private cost. It is similar to the ‘polluter pays principle.‘ – which was incorporated into international law at the 1992 Rio Summit. It simply means those who cause environmental costs should be made to pay the full social cost of their actions.
