Generally, established companies have a lot of trouble, and often fail, adopting when the rules of business change.
In this case, Shell is having a lot of trouble adopting to carbon-free (or neurtral) energy.
IMO: I think the best approach is to seek out carbon-free (or neutral) energy business models and disrupt Shell out of business. From Shell's POV, the best thing they can do is invest in the disrupters and have them organically displace their existing fossil-fuel based businesses.
