Bring a large pot of salted water to a boil. Add the noodles and cook as the label directs, then drain.
Meanwhile, make the sauce: Combine the green tea, peanut butter, soy sauce, vinegar, brown sugar and peanut oil in a blender. Add the sesame seeds, chili-garlic sauce, sesame oil, ginger, garlic and 1/4 teaspoon salt; process until smooth.
Toss the noodles with the peanut sauce and carrots in a large bowl. Chill about 1 hour. Top with cilantro, peanuts and more sesame seeds.
