A direct and personal message to the CEO and key decision makers are best. If you’re a current or potential customer or shareholder, do mention that as well.
Here are some questions you could ask:
- Why is Chubb insuring the Trans Mountain pipeline, even though another Swiss company, Zurich, just dropped its coverage in the dirty tar sands pipeline? 
- Chubb is a industry leader when it comes to not working with Coal companies, when will it do the same for climate destroying pipelines? 
- What chance will our grandchildren think of the choices we made at this critical time for our climate?
