How much of Earth is carbon-based? Description

Carbon ($C$), makes up for the majority of our planet and everything that lives on it. Coal, gems (any gem), plants, and most sedimentary rocks also contain great deals of carbon.


  Fun fact: Coal is almost purely carbon; due to it being made entirely of decayed plants and animals.


Question

I'd prefer a fraction or percentage answer (ex. about 1/3 or 34%) Rounded, if you would.


  About how much of planet Earth is carbon based?


Proportion of $C$ to really anything else.
0.07% of the mass of the Earth is estimated to correspond to carbon atoms (computed from data on Abundance of the chemical elements that comes originally from this paper)

The following table is from the above link and show the relative abundances on Earth in parts per million of mass:


The original table in the source paper (which correspond to Chapter 1 in, EARTHQUAKE THERMODYNAMICS AND PHASE TRANSFORMATIONS IN THE EARTH'S INTERIOR) is this one:
