The mark consists of a green outline of a circle is filled with the color grey. Outside of the circle the words "BIOMASS - RENEWABLE - SUSTAINABLE" are located on the same 360 degree continuous baseline. All letters of the literal element are capitalized, non-serif, and black in color. Three black dots separate the three words. An image of a leaf is centered in the foreground of the grey-filled, green-outlined circle. The leaf image has a continuous perimeter and is filled with graduated dark-to-light green shading beginning with solid color at the bottom of the leaf image and gradually fading to a lighter green at the top of the leaf image. The leaf has two outlines, both of which begin just below the widest (left to right) part of the leaf. The first outline is touching the green leaf image and is thin and yellow in color. The second outline is located outside the yellow outline, is thicker than the yellow outline, and is graduated in color. The second outline fades from yellow near the bottom of the leaf image, to orange near the middle of the leaf image, to red at the top of the leaf image.
