As you've correctly mentioned the statue of liberty is very common amongst company logo and so is the world map. Having considered this, I used the Liberty Flame and a globe symbol to fit in your requirements.
Any feedback that could make this concept better is appreciated.
We love this concept of the flame/globe. To compare, can we see one where the globe is the solid green/blue map incorporating a more solid flame? Not sure if a yellow/orange/red flame would be too much - you could try one with a contrasting flame, and one with the green flame.
Also, can you change the slogan to 'Understanding and Creating Prosperity". We are working on the best slogan, so it may change again.
