Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more
