Glencore, a company that's expanding a massive coal mine in Queensland, Australia, is going to destroy a massive amount of koala habitat - and plans to buy 'koala offsets' to claim they've undone that damage www.theguardian.com/australia-ne...
6.0 Final Score and Offset Liability
Significant residual impacts will occur to environmental matters from the development of the
study area and environmental offsets will likely be required through the State and
Commonwealth approvals process. A land-based approach is required for significant
residual impacts to MNES and a land-based approach should take precedence for MSES as
these can be co-located in a single or multiple offset areas. Any residual MSES not covered
by a land-based approach can then be sought through a financial settlement.
6.1 Combination Offset for MSES
A land-based offset will primarily be sought for those State prescribed environmental matters
where a significant residual impact will occur (Table 27). Any proposed offset area for MNES
can also be ground-truthed for those prescribed environmental matters in Table 27. Any
residual quantity for those prescribed environmental matter not covered by a land-based
option may be sought through the DES web-based financial settlement offset calculator.
6.2 Land-based Offset for MNES
A referral and subsequent approval under the EPBC Act is required for significant impacts to
MNES. Overlapping significant environmental matters within the study area where a
significant impact under the EPBC Act have been identified as likely to occur include Koala
and Squatter Pigeon (Southern) habitat (Table 31). Given that significant impacts to MNES
will occur within the study area, offsets in accordance with EPBC Act offset policy will be
required. Note that there is a minimum of a 90 % land-based offset mechanism required
under the EPBC Act offset policy. Multipliers for land area are determined via a number of
parameters, many of which are dependent on attributes of a suitable offset land parcel, and
will therefore be determined when additional information from the offset strategy is available.

been identified
