What is biodiversity offsetting and what does it mean for your project in NSW?

News & Insights

Biodiversity offsetting specialist Dr Amanda Griffith introduces the basics of biodiversity offsetting, and how it applies in NSW.

Biodiversity offsets aim to deliver beneficial and sustainable environmental outcomes and are an integral component of most project approvals in Australia.
In NSW, the Biodiversity Offsets Scheme (BOS) provides the framework for assessing impacts to biodiversity. It seeks to balance development with protection of our environment. Key to the scheme is the requirement to avoid and minimise impacts wherever possible and then offset any unavoidable impacts. Recent judgements in the Land and Environment Court have revealed that clearly demonstrating efforts to follow the hierarchy of “avoid, minimise and then offset” may be critical to project approval.

Biodiversity impact assessments – generating an offset/credit requirement

Where impacts of land clearing for development are unavoidable, project proponents may be able to offset the “cost” to biodiversity by purchasing biodiversity credits.
In NSW, an accredited assessor will apply the Biodiversity Assessment Methodology (BAM) to prepare a Biodiversity Development Assessment Report (BDAR) identifying the number and type of credits required to offset a project’s impact on biodiversity. The number and type of credits will depend on the quality and area of vegetation/habitat impacted. There are two credit types: ecosystem credits are generated through impacts to vegetation communities; species credits are generated for impacts to threatened flora and some threatened fauna species.
Note, the BAM provides highly prescriptive survey requirements which must be followed and can be an expensive and time-consuming process. Getting early advice regarding potential time and cost implications will minimise risks to project timeframes and budgets.

Discharging a biodiversity credit requirement

To meet a project’s biodiversity credit requirement, developers have three options:

  • Purchase biodiversity credits directly from the open market (credits that have or are being generated at an offset site)
  • Establish their own offset site
  • Pay a premium for the credits to the Biodiversity Conservation Trust (BCT) who then take on the responsibility of settling the credit requirement.


Biodiversity credits – the source of credits

Credits are generated when land containing biodiversity values is protected and managed for conservation in-perpetuity, at an established Biodiversity Stewardship Site (or BioBanking Site under the previous legislation). The NSW Biodiversity Conservation Trust (BCT) approves and administers the establishment of offset sites.  It is our experience that assessment and approval of offset sites is a time-consuming process (one to two years); again understanding this early is important for project and business imperatives.
The establishment of offset sites presents a potentially significant opportunity for landholders in NSW. Landholders with land containing biodiversity values can – with the help of an accredited assessor – sell biodiversity credits to developers seeking to meet their project’s obligations while retaining ownership of their land and managing it as a biodiversity offset site.

Biodiversity offsetting strategy

Purchasing biodiversity credits can be extremely costly, however with the right strategic advice early in your project’s planning phase, it is possible to meet offset requirements efficiently and to turn offset liabilities into positive, income-generating outcomes.
Matching the biodiversity offsetting needs of developments with the biodiversity offsetting resources of landowners can provide exceptional commercial and environmental outcomes.
