Grounded and responsible firms—and those grounded and responsible firms can actually tie into the strategy that Leanne Wood raised earlier of environmental benefit, particularly where they grow locally based, locally sourced supply chains in the foundational sector, which can reduce carbon footprints. We had Redrow housing in our Economy, Infrastructure and Skills Committee last week and asked them if they'd made any assessment of the impact on local supply chains, and they said, no, they'd made no assessment whatsoever of their impact on local supply chains. Therefore, is it not the case that foundational companies, locally sourced companies, can have a very positive impact on a policy of green growth?
