Many companies have little or no knowledge of the Scheme and respondents felt it important to raise awareness. A single trading scheme is preferred. Many respondents agree that participation should be on the basis of all a company's operations within a given sector to avoid cherry picking. However, many question the definition of a sector and think that provisions for entering only part of a business should be considered further. A few respondents noted that company participation on a sectoral basis may not be compatible with the arrangements made for participation in some forms of Agreements.
Some respondents agree with the allocation of emissions from electricity generation to end users.
However, there is widespread concern that the fixed carbon rate for these indirect emissions will create discrepancy between actual reductions of emissions and calculated reductions of emissions. In addition, should generators also take on caps, thereby including both generators and end users, there is concerned that the fixed carbon rate will introduce double counting of emissions reductions. Including both generators and end users is not simple or transparent and will introduce uncertainty and complexity. Whether the Scheme's participants are solely end users, or both generators and end users, there could be incompatibilities with other national trading systems, a future EU scheme or an international scheme. The generators feel concerned that their role in the Scheme has not been fully addressed.
