The Excise Department wants to complete its study of carbon tax collection measures this year, says director-general Ekniti Nitithanprapas.
He said most nations opt for one of two methods when imposing a carbon tax: a levy on carbon dioxide-emitting products, or on factory production processes that emit a high level of carbon dioxide.
Mr Ekniti said the EU levies a tax on the production process pertaining to both local and imported products.
