PJA Carbon Calculator

In March 2013, the Pipejacking Association (PJA) launched its Carbon Calculator, comparing the C02 emmissions from pipejacking or microtunnelling against a similar construction by open-cut trenching. The calculator was developed for the PJA by TRL (Transport Research Laboratory) and verified by indepenedent consultancy WRc.
