“Whilst mass
balance is probably the most
|
|
|
accurate way to
measure emissions, it is also
|
|
|
complex and hence
expensive. Some of the
|
|
|
facilities that
you are interested in may have
|
|
|
used a mass
balance measurement, but the NPI
|
|
|
does not record
the method used. You can find
|
|
|
out the method
employed by contacting each
|
|
|
facilities
'public contact' officer, whose contact
|
|
|
details will
appear on the facilities data sheet”.
