Logo design for website 'My Carbon Coach'

My Carbon Coach is a social media website, online community and global campaign for individuals to 'carbon coach' themselves. With carbon foot-printing facilities, discussion forums and peer blogging, users can share knowledge, information and experience of their transition to a low-carbon lifestyle. The site aims to capture a global audience with a strong community feel. We want the site to attract users from all nations and to provide a 'global village' feel with us all being citizens of one "Earth Nation." The purpose of the site is for people to collective reduce carbon emissions in a positive way - the logo should reflect this and not get caught up in eco-cliches. Users can set voluntary carbon reduction targets for themselves and submit their personal carbon disclosure. We are looking for a textual and illustrative logo for the site. The logo should be simple, sleek and modern. The logo should be easily readable, distinct and recognisable. It is to represent a brand, campaign and website. Think: fresh, self-empowerment, people-powered, authentic, self-accountable, self-leadership, momentum for change and action centred leadership. Ideally, the colours for the logo should be neutral (purple or sky blue) but creative ideas welcome.

Many thanks.
