I ended up flipping the sentence around. Instead of writing that one thing implies the next, it felt natural to write that the latter is implied by the former. Essentially the voice is changed from active to passive. When writing prose it is normally advised against using the passive voice, but in this case it can give a more formal feel, and help vary things up.
All environmental factors, such as consumer confidence and interest
rates, are automatically accounted for due to the nature of the model.
Instead of due to a simple by can also suffice
All environmental factors, such as consumer confidence and interest
rates, are automatically accounted for by the models nature.
You can use due to while keeping the active voice as well
Due to its nature the model will automatically account for all
environmental factors such as consumer confidence and interest rates.
and by in a dependent clause
The model will, by its nature, automatically account for all
environmental factors such as consumer confidence and interest rates.
In short, rather than just focusing on varying the words, change up the structure as well, it will often necessitate the use of new words anyway.
I also see I've opted for will account for (future perfect?) rather than your accounts for (present indicative?). That wasn't a conscious choice.
