P a g e | 52 The trick with alternative PCC mix design and processes is the same as in asphalt concrete manufacturing. Achieve maximum, realizable carbon reductions while not degrading overall materials performance and durability. As discussed, paving materials carbon reductions, while worthwhile, will be greatly limiting and unlikely to have a material impact on total road-associated carbon. PCC emissions are a high priority among regulators, agencies, and activists as they are among the highest in the industrial sector. They are anticipated to be ~27% of all industrial emissions by 2050, up from just 23% presently (Figure 27) .
