I have a question related to OpenLCA. I imported my outputs in the software, but it seems that it is mandatory to give a specific amount for the output. I think the purpose of calculation with this software is to evaluate the output amount, and basically, this is the reason we are using this software. In SimaPro software, there are some libraries, and based on these libraries, we can have an accurate amount of output, and I could not find such this thing in OpenLCA. For example, for my project, I am going to consider air emissions as the output, and the air emissions include carbon dioxide fossil, carbon dioxide biogenic, nitrogen oxides. My questions are:
1. How do I find the output values without any library?
2. If there is not any library in the software, what are the criteria for giving specific amounts to the outputs?
3.If there is library in the OpenLCA. How can I use the library?
