Definition 

Internal carbon pricing (ICP) involves companies setting a price on carbon emissions within their own operations, which can help them identify their carbon footprint and to engage a transition to a low-carbon economy. The disclosed level of internal carbon prices can depend on macroeconomic, regulatory, industry, and firm-specific characteristics. There is a wide diversity of ICP both by industrial sector and by region, due to the non-existence of global standards for pricing of carbon emissions.
