The CRL project has adopted the Infrastructure Sustainability Council of Australia’s (ISCA) Infrastructure Sustainability (IS) rating framework. It is one of the pilot projects using this framework in Aotearoa.
The framework is a comprehensive rating and certification tool for evaluating sustainability across the project's design, construction and operation.
The CRL project aims to achieve an overall rating of “excellent” by satisfying the criteria within the 6 themes:
The IS rating tool focuses us on:
- Modelling and measuring resource consumption.
- Identifying and implementing feasible opportunities to reduce consumption.
- Achieving significant reductions in resource use across the infrastructure lifecycle.
CRL is working with Mana Whenua to recognise Te Tiriti o Waitangi and identify opportunities to respond to New Zealand’s cultural context within this framework, ensuring the sustainability criteria are compatible with te Ao Māori.
CRL was recently awarded a "Leading" Infrastructure Design rating by ISCA. Read our Sustainability Rating news article for more information.
The City Rail Link project is the first public transport project in New Zealand to measure its carbon footprint. AT is calculating the carbon emissions associated with the construction and operation of the stations and tunnels to produce a carbon budget for the project.
During construction, data from energy, waste and water reports as well as delivery information for materials will feed into the carbon footprint calculations. Considering opportunities for innovation and improvement will also be part of our ongoing analysis.
Zero waste to landfill
Throughout construction, the project is striving to send zero waste to landfill. Designing for waste minimisation is a priority to support this aspirational goal, and our contractor's waste management plans (which will be key) will identify:
- Likely sources of waste and when they will arise.
- Strategies for implementing the waste management hierarchy of
avoid– reduce – reuse – recycle – recover – treat – dispose.
- Systems to monitor and report on waste.
- Predicted quantities and diversion paths.
To support our understanding of the CRL sustainability journey and to contribute to the IS rating, we will be monitoring and reporting on our energy and water use, and waste generation.
This report outlines the CRL’s sustainability journey to date. Read about our vision, the sustainability approach, how we are reducing the construction and operational impacts, striving to send zero waste to landfill and engaging positively with the local community.
