According to its website "ACIL Tasman is an economic consulting firm providing analysis and advice on economics, policy and strategy to clients in Australia and internationally." It was formed after the Tasman Institute merged with ACIL Consulting.
ACIL's clients include many associations and companies with vested interests in preventing effective emission reduction policies being introduced. They include the Australian Industry Greenhouse Network, the Australian Coal Association, the Australia Petroleum Production, the Electricity Supply Association of Australia, the Minerals Council of Australia, and Exploration Association, the Australian Aluminium Council, Alcoa, BHP, Rio Tinto, Woodside, Shell, Mobil, Chevron and Santos. Despite receiving millions of dollars from greenhouse gas polluters, ACIL Tasman has often been hired as a consultant to various federal and state government departments on various global warming related matters ("often without an open tender process").
According to Guy Pearse, ACIL Tasman "has been the most constant private analytical prsence int he greenhouse debate in Australia". Its research exaggerates the cost of greenhouse gas reduction policies including carbon taxes, emissions trading and the mandatory renewable energy target (MRET). It instead promotes the public funding of new technologies such as carbon capture and storage and emphasises the contribution that coal and alumninium make to the Australian economy.
