Senator Chris Evans: The Prime Minister has provided the following answer to the honourable senator's question: I am advised that the carbon price will be applied to those companies that have operational control over a facility that emits over 25,000 tonnes annually of CO2-e emissions, except where those companies are in sectors not covered by the carbon price. Estimates of the number of companies that will be liable to pay a carbon price is largely based on emissions data previously reported under the National Greenhouse and Energy Reporting Act 2007 (the NGER Act). Of the estimated 500 businesses to be subject to a carbon price: around 60 are primarily involved in electricity generation; around 100 are primarily involved in coal or other mining; around 40 are natural gas retailers; around 60 are primarily involved in industrial processes (cement, chemicals and metal processing); around 50 operate in a range of other fossil fuel intensive sectors; and the remaining 190 operate in the waste disposal sector. Given that only greenhouse gas emissions and energy consumption data can be published by the Greenhouse and Energy Data Office, it is not possible to provide details of corporations listed on the NGER Register as this would breach secrecy provisions under the NGER Act
