About this paper
An assessment of international models used to implement fuel quality standards is necessary before any model for Australian fuel standards can be determined. There are a variety of models that are used internationally to implement fuel quality standards. In the simplest terms, the models fall into three categories: flat limits; averaging limits; and, emission limits models.
- Flat limits require that each batch of fuel supplied by a refiner or importer must comply with certain limits (typically maximum and minimum content limits) for particular fuel parameters.
- Averaging limits require that fuel supplied by a refiner or importer must, over a specified time period, comply with an average limit (but not exceed a cap limit) for particular fuel parameters.
- Emission limits require that fuel supplied by a refiner or importer meet certain emission effects for particular fuel parameters. These effects must be equivalent to outcomes determined by specified limits or reference test fuels.
This paper outlines a description of the current models used to implement fuel quality standards, discusses their advantages and disadvantages, and identifies a preferred model for use in Australia.
This discussion paper is one of several discussion papers made available for public consultation to work towards setting national fuel quality standards. This discussion paper is now closed for public comment.
