Question Weird simple question on comparing positive and negative integers

Hi, I don´t know how to deal with this:

When comparing climate impact (contribution of CO2 released to atmosphere) of different types of insulation, how do I compare the positive and negative impact? I want to compare this materials:
CORK -59 kg/m2
EPS +23 kg/m2
WOOL +96 kg/m2
__________
I can say that WOOL has 4,17 times bigger contribution than EPS.
How many times bigger is contribution of WOOL or EPS in comparison with CORK?
(mathematicaly -1,63 times, but that as an explanation doesn´t make sense, it´s not possible to imagine)

I will be very happy for help.
