Angular 2 share the same css file across the module

It's possible to share the same css file across the same angular 2 module?

I know that I can set View Encapsulation Emulated to inherited parent component css but I want to share the same style across one particular module of my app.

This is my app structure:

• Main component
  • Module A (shared css style for this module)
    • Component 1
    • Component 2
  • Module B (shared css style for this module)
    • Component 1
    • Component 2
