A system which is running in the Netherlands and in Flanders (I)
→ because of the tight Kyoto burden sharingin Flanders large installations started up between the Kyoto reference year 1990 and the Kyoto protocol year 1997.
→ the policy not to obstruct growth of companies
companies with a good prospect for future are those who grow.

A system which is running in the Netherlands and in Flanders (II)
→ government did not want to impose absolute caps on energy consumption or greenhouse gas emissions…
→ … but expects optimised energy efficiency of production installations, in a quantified way
→ standards must be set; the benchmarking system is the way to these BAT-standards

General outline of Benchmarking
→ the company makes a split up of its facilities into benchmarkable installations
→ for every installation a study is performed to compare energy efficiency with similar installations in the world
→ for energy intensive installations it is assumed that the best installations are BAT
→ the BAT-standard allows a certain margin→ the covenant requires to attain the standard

1) Full benchmarking of all installations in the world; the decile point gives the standard (Decile method)
۔ may require a lot of data۔ co-operation of all important world actors is
necessary۔ result is very acceptable, irrespective of the
consumption span۔ irregularities are rare
Benchmarking methodsThe benchmarking methods, in order of application priority are:

2) Benchmarking in the best region in the world; the average consumption of the installations in the best region gives the standard (Region method)
۔ first a best region must be defined۔ that region must be acceptable as BAT-
standard for the world۔ definition problems about number of regions
and number of companies in the region۔ difficult method۔ method may be desirable to limit the number
of installations of the full benchmark

3) Best Practice: the world best installation has to be found and to be assessed; standard = world best + 10%
۔ good feasibility in terms of investigation work۔ proof of “world best” is not evident, but more
feasible than for the region method۔ 10% may be too tolerant as margin

4) Auditing: if other methods fail, the installation must be thoroughly audited – standard = own installation after execution of all economically efficient measures (I.R.R. > 15%)
۔ this method gives little handhold۔ results are often disputed

In Flanders: ۔ Covenant approved by government on 29.11.2002
for companies > 0,5 PJ, later also companies which must participate in system of emission rights (T.E.R.)
۔ 176 companies participate in the Covenant۔ commitment to achieve BAT, to be specified in an
energy plan۔ energy plans submitted 30.06.2004, by all T.E.R.-
companies۔ all energy plans to be verified by 15.09.2004
State of the art of the Covenant

Is Benchmarking an easy way to find BAT-standards?
Unfortunately not…every installation has its own
difficulties!
