One of the newest faces at Exxon Mobil Corp., Kaisa Hietala, wants to make sure she¡¯s not misunderstood as she¡¯s propelled to sudden fame in a battle between climate activists and the oil industry.

The 50-year-old Finn ¡ª unknown to corporate America until last month ¡ª won her boardroom seat at Exxon after a campaign by activist hedge fund Engine No. 1 convinced BlackRock Inc., Vanguard Group Inc. and other key investors to back her in a contentious vote.

Speaking in an interview, Hietala says she understands how important it is to look after a company¡¯s ¡°traditional, existing business.¡± That¡¯s after devoting her career to helping the energy industry move away from fossil fuels and over to renewables.
