The 17-year-old presented the Entourage alum, 39, with the 2016 Paul Walker Ocean Leadership Award at the Monterey Bay Aquarium in Monterey, California.
Earlier in the week, Meadow teased the event by posting a photo of herself on the beach via Instagram.
“Excited to honor my dad’s legacy at our @PaulWalkerFdn Ocean Leadership Award Presentation @MontereyBayAquarium this Saturday,” she captioned the pic.
Grenier — who was honored for his work with the Lonely Whale Foundation, which promotes ocean health awareness through conservation — posted a shot of himself, Meadow and the aquarium’s executive director Julie Packard on Twitter on Saturday.
“Honored to share my voice today,” he wrote. “Thank you @paulwalkerfdn for recognizing my work with @lonelywhale. #DoGood.”
In April, Meadow was awarded $10.1 million in a settlement from Roger Rodas’ estate. Rodas was driving the car that Meadow’s father, Paul, was traveling in when they were both killed in a fiery accident in Santa Clarita, California, in 2013. The Fast and the Furious actor was 40.
Last year, the teen started The Paul Walker Foundation. “Reflecting on my father, I found myself reflecting on his passions,” she wrote on Instagram in September. “His passion for the ocean, his passion for rescuing animals, his passion for helping people and his passion for spontaneous goodwill. I wanted to start this foundation because I want to share that piece of him with the world. I want to share that part of him with others. … I can’t think of a better way to celebrate my father.”
