Governance and reporting

The project's sponsors, the Crown and Auckland Council, expect CRL to be designed, constructed and operated to achieve sustainability excellence. This is set out in CRL Ltd's Statement of Intent, and is reported to sponsors annually against the Statement of Performance Expectations.

CRL is being designed, procured and constructed to generate the greatest long-term environmental, social and economic value from the considerable resources needed to deliver the project. This will result in:

• an asset that has a carbon footprint optimised over its 100-year design-life • a construction process that minimises the amount of waste sent to landfill • training and employment opportunities for those experiencing barriers, disadvantage or discrimination in the labour market • supply chain opportunities for Māori and Pasifika small and medium size enterprises and socially innovative businesses.

Link Alliance commitments

Many of CRL Ltd's performance expectations are being delivered by the Link Alliance on Contract 3. Embedded within the alliance's strategies and objectives are the following commitments:

• minimising waste and limiting visual, air quality, water quality and noise impacts • integrating sustainability in design, construction, operation and maintenance • maximising opportunities to support local businesses and suppliers • recognising the broader dimensions of the environment including social, cultural, economic and natural • maximising opportunities for training and skills development for the widest possible group of people • protecting and promoting our cultural and historic heritage for future generations.

Infrastructure Sustainability

ISCA's IS framework is a comprehensive rating and certification tool for evaluating sustainability across project design, construction and operation.

The CRL project adopted the IS rating framework to evaluate and drive sustainability performance. We adapted the framework in collaboration with Mana Whenua to ensure it is appropriate within the context of Tāmaki Makaurau.

The CRL project continues to meet criteria across the framework's six themes:

• management and governance • using resources • emissions, pollution and waste • ecology • people and place • innovation. The IS rating tool ensures the project focuses on:

• modelling and measuring resource consumption • identifying and implementing feasible opportunities to reduce consumption • achieving significant reductions in resource use across the infrastructure lifecycle.

There are three levels of performance -

• Leading • Excellent • Commended.

CRL Ltd has required Contracts 1, 2 and 3 to achieve at least 65 points, which would result in at least an 'Excellent' rating.

To date both Contracts 1 and 2 have achieved a Leading Design rating. Contract 2's As-built rating is currently being processed.
