Here are my revisions with the requested from you changes. As you wished, the attention now is more in the "Sustainability Group" part of the name, where "Boston Area" is secondary. I still keep both text groups separated but if you need them all in one line, please let me know.
About the font types, as you can see I've used several combination of different font styles - bold, UPPERCASE, serifs and sans-serifs. I could easily refine the font part of the logo if you give me a little better direction of what you would like to see.
Hope to have your feedback.
Thanks
