The mark consists of the lowercase letters of "ib" and the intentional uppercase "E" for the word "environmental." The upper case "E" highlights that the ENVIRONMENT is the emphasis, as opposed to the founder's initials of “i” and “b.” These letters/words appear in the top half of the logo. The green arrows around the logo represent the environmental concepts of the water cycle, as well as recycling. The blues in the middle of the logo represent the sky (upper portion), related to clean energy; while the medium blue in the middle symbolizes water; and the darkest blue in the lower portion represents the ocean and its resources.
