Our aim is not to “drain the ocean” in a few months but to add a voice of engineering insight to the debate, demolish potential myths and legends and suggest some sensible ways forward. We don’t expect to achieve pinpoint accuracy in our investigation, but we can be honest about that. We want to establish some genuine truths and point to where more work or funding should be focussed. We need more information and guidance to existing reliable reports and research on carbon in materials mining and manufacture, infrastructure provision, renewal and maintenance, and end of life recycling.
