So, why would CMLCA claim to be scientific software? Of course this is subjective and
debatable, but there are good arguments:
It is probably the only software for LCA that has been developed entirely at a university.
It has been designed with university students, PhD students and academic staff as the primary audience,
whereas most LCA programs have a prime focus on consultants.
The internal machinery has been described in the scientific literature, to a far better extent than
that of other LCA programs.
Concerning this last point, important aspects has been published in the following books:
