The auction share should be expressed as a percentage figure in Directive 2003/87/EC of the European Parliament and of the Council [4], to enhance planning certainty as regards investment decisions, to increase transparency, to minimise carbon leakage, and to render the overall system simpler and more easily understandable.
Ba cheart an scair a chuirfear ar ceant a shloinneadh mar fhigiúr céatadáin i dTreoir 2003/87/CE ó Pharlaimint na hEorpa agus ón gComhairle [4], chun an chinnteacht pleanála i ndáil le cinntí infheistíochta a fheabhsú, chun trédhearcacht a mhéadú, chun sceitheadh carbóin a íoslaghdú, agus chun go mbeidh an córas foriomlán níos simplí agus níos sothuigthe.
