Offsetting in the context of policy

What happens to the theory when it hits the real world?

Biodiversity offsetting is a highly topical and increasingly popular approach used to compensate for impacts on species and ecosystems as a result of development, and is the subject of a large and growing body of scientific research. There has been substantial work in developing offset metrics (Miller et al, 2015) which can accurately measure biodiversity losses and gains over time, as well as discussion around the ecological limits of offsetting (Maron et al, 2012). However, there has been comparatively less attention paid to how the policy system as a whole influences the possible environmental outcomes from biodiversity offsetting.

For instance, what are the roles and responsibilities of key organisations involved in offsetting, how do these organisations interact, and do they have sufficient capacity and ‘fit-for-purpose’ information to implement and oversee offset policy? What institutional settings are in place to govern the offsetting process? What legal mechanisms are used to transfer and enforce offset obligations between different participants? Are there appropriately aligned incentives to stimulate market participation and to facilitate monitoring and compliance?

To explore these many dimensions of offsetting policy we brought together fifteen academics and professionals from law, economics, business, ecology and policy for a two day workshop at ANU at the beginning of 2015 (see box on ‘Legal and institutional dimensions of biodiversity offsetting’).

By considering these institutional and organisational dimensions of biodiversity offset markets, in addition to key criteria for the effective implementation of environmental policy, workshop participants were able to identify a range of issues arising from the offset implementation process which may be impeding positive outcomes for biodiversity.

From good design to good outcomes

Although it was recognised and agreed that the recently updated Australian environmental offsets policy guide had introduced scientific rigor and improved transparency in the calculation of offset requirements, this has not necessarily led to improvements in other aspects of policy implementation. For example, it was pointed out that translating the offset requirements calculated at the design phase into on-ground implementation is still a rather complex process.

A better understanding by policy-makers of the challenges that on-ground offset providers can face (such as availability of native seed stock), and the unique insights these practitioners can bring to the table (such as knowledge of new management and restoration techniques), could help to ensure that the biodiversity outcomes that are promised by offset proposals are actually achieved on the ground.

What are the roles and responsibilities of key organisations involved in offsetting, how do these organisations interact, and do they have sufficient capacity and ‘fit-for-purpose’ information to implement and oversee offset policy?

Policy uncertainty

Biodiversity offsetting is a rapidly evolving policy space, which means that government policies have been through a number of changes in a relatively short space of time. For example, the Queensland Government introduced on average, one new offset policy per year over the 2000s. The introduction of new policies may be motivated by a number of reasons:

  • a need to provide more guidance or to better address the problem at hand
  • to incorporate new information as it comes to light
  • to adapt the policy to respond to a variety of interest-group pressures.

The downside is that it continually shifts the goal-posts for businesses who need to comply with such policies when developing environmental impact statements and submitting development applications.

Securing an offset site which can provide adequate compensation for the impacts of a development is a long, complex and expensive process, requiring negotiation with many parties including landholders, banks, brokers, Federal, State and local governments and third-party offset providers. If a policy is changed or re-interpreted during this process, investments of what can sometimes be millions of dollars tied to an offset project may be at risk. This uncertainty can have a very real impact on what outcomes can be delivered by an offset policy.

People, culture and relationships

Although the main concern about biodiversity offsetting is of course the species and ecosystems being impacted and compensated for, ultimately it is the individuals and organisations who implement the policy that can influence its effectiveness. For example, if information about what the offset requirements are, what legal mechanisms are needed to secure the offset, or what actions are required for regulatory compliance are not adequately communicated among all participants, this can result in offsets that provide less enduring and effective outcomes for biodiversity.

It’s crucial to recognise that the motivations and objectives of individuals and organisations involved in offsetting will often differ.

Identifying where there may be opportunities to better align policy processes in a way that is mutually beneficial could help to improve outcomes for biodiversity through offsetting in the long term.

More changes are on the horizon

Biodiversity offsetting is certainly an active policy space in Australia. In addition to the recent Senate inquiry, there have been new policies introduced in Queensland and New South Wales during 2014. Concerns have been raised about the relaxation of key policy principles in these new policies, such as the ‘like-for-like’ principle (ensuring an offset is the same species or ecosystem type as the one impacted), permitting mine rehabilitation (which is already required under the NSW Mining Act) to be counted as an offset, and allowing up to 100% of an offset to be ‘indirect’ (which is really a change in the definition of the term ‘offset’).

Although these changes have likely been driven by politics rather than science, this is simply a reality in the making of public policy – which results from an interaction between different values, interests and resources. The role which researchers can take in this process is to do provide the best possible science, while remaining cognisant of this broader contestation of ideas.

On reflection

The ideas presented in this editorial capture some of the topics which were discussed by workshop participants, which included researchers who specialise in economics, public policy, law and ecology, as well as professionals from Government, business and legal and environmental NGOs. The key outcome arising from the workshop was the identification of a range of non-ecological issues which can influence the ecological outcomes resulting from biodiversity offset policy.
