The constructor backs contractual risk allocation that favours low-carbon solutions and, where it needs challenging, works with the owner and the other parties to reach terms everyone can accept; shows in its bids how it will find the relevant low-carbon options and, where fitting, which carbon-cutting measures the bid includes; looks at how its subcontracts can support the scheme's carbon targets and low-carbon solutions in keeping with the owner's process; keeps the owner regularly informed of performance against the agreed carbon targets with the same weight as cost and programme; shows how it will satisfy the owner's carbon management process; reviews its own buying categories for material carbon effect, writes proportionate tender criteria for suppliers able to deliver low-carbon results and, where required, builds low-carbon solutions into its bids; and promotes its own low-carbon solutions, tells its chain its carbon targets and the part they play in meeting them, goes back to its chain from time to time for low-carbon techniques and products, and looks for chances to build skills and capability together.
