The world is facing a climate change emergency and the creation and operation of built assets is a contributor to the problem. The sustainability of creating and operating buildings and infrastructure will need to dramatically increase in order to achieve net zero emissions of carbon dioxide and other climate-warming gases.
Reducing the impact of creation, operation, maintenance and disposal of assets on climate change is principally a technical issue addressed in the Scope. However, there are limitations in this approach as it relies on users including the required content in the Scope and linking this to the contractual processes in the contract.
Introducing additional conditions of contract was seen as beneficial in driving the reduction of the impact of the works on climate change.
- Signposting to the issues to be covered in the Scope / raising its profile
- Incentivising performance against climate change targets
- Adding to existing processes or creating new processes that support the reduction of the impact of the works, service and supply on climate change
This has led to the development of X29.
Combatting climate change has to be considered at every point in the life of an asset and needs the engagement of clients and all key members of the supply chain. To support this a version of secondary Option X29 has been produced for all NEC4 main and main subcontract forms.
We welcome feedback on the use of secondary Option X29 and are keen to support the capture and development of best practice examples and look forward to engaging with users to do this.
