How Corymbia Credits and the Gum Tree Lane Methodology Work
Corymbia Credits are premium, nature-based environmental credits created under the Gum Tree Lane Methodology — a leading Australian framework designed to channel private capital into the protection and restoration of nationally significant biodiversity areas.
The methodology allows landholders to generate credits by delivering measurable, long-term environmental improvements. Companies and institutions purchase these credits to meet biodiversity, ESG, or nature-positive targets with credible, verifiable outcomes.
Process Overview
Site Assessment
Eligible sites are nominated by landholders and undergo a detailed ecological assessment by accredited professionals to evaluate baseline biodiversity value and restoration potential.
Baseline Establishment and Management Commitment
A scientifically verified ecological baseline is established. Landholders commit to a long-term management plan detailing conservation activities such as habitat protection, weed control, or reforestation.
Credit Issuance and Sale
Credits are issued upfront based on the verified baseline and management commitments. This avoids the need for annual reissuance and provides both revenue certainty for landholders and cost certainty for buyers.
Segregated Fund Management
Proceeds from credit sales are held in a segregated, multi-signatory bank account on behalf of project participants. This structure ensures that buyer funds are protected and only released in accordance with verified project milestones, safeguarding buyers in the event of underperformance.
Ongoing Verification and Reporting
Independent third-party verification ensures the project remains on track against its ecological goals. The methodology allows for adaptive management to respond to changing environmental conditions.
Key Differentiators of Corymbia Credits and the Gum Tree Lane Methodology
Upfront Credit Issuance
Credits are issued at the beginning of the project, giving immediate funding certainty for landholders and fixed, upfront costs for buyers without future exposure to market volatility.
Segregated Accounts for Buyer Protection
Buyer funds are safeguarded in a segregated account, providing clear financial security and ensuring that payments align with ecological delivery.
Science-Based, Outcome-Focused Approach
Projects must demonstrate measurable improvements against an established ecological baseline, verified by independent auditors.
Proponent-Led Flexibility
Landholders have flexibility to design and implement conservation actions suited to their unique site conditions, promoting better and more sustainable outcomes.
Alignment with Global Best Practices
Corymbia Credits are structured to align with emerging standards such as the Taskforce on Nature-related Financial Disclosures (TNFD) and Science-Based Targets for Nature (SBTN), providing buyers with confidence in the quality and durability of the environmental outcomes.
Not-for-Profit Governance, Market Access
Managed through a not-for-profit custodian to prioritise environmental outcomes, Corymbia Credits also maintain access to private and institutional buyers to maximise conservation impact at scale.
