Governance and reporting

The project's sponsors, the Crown and Auckland Council, expect CRL to be designed, constructed and operated to achieve sustainability excellence, as 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 Link Alliance on C3. Embedded within the strategies and objectives are the following commitments:

• To minimise waste and limiting visual, air quality, water quality and noise impacts

• To integrate sustainability in design, construction, operation and maintenance

• To maximise opportunities to support local businesses and suppliers

• To recognise the broader dimensions of the environment, including social, cultural, economic and natural

• To maximise opportunities for training and skills development for the widest possible group of people

• To protect and promote our cultural and historic heritage for future generations.

Infrastructure sustainability

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

CRL 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.

CRL 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 C1, C2 and C3 to achieve at least 65 points, which would result in at least an 'Excellent' rating.

To date both C1 and C2 have achieved a 'Leading' Design rating, C1 a 'Leading' As Built rating and C2 an 'Excellent' As Built rating.

Delivering CRL safely and sustainably requires a shared commitment and collaboration - we acknowledge the efforts of all.
