CleanCruising.com.au is the first cruise agency that offers "carbon neutral" cruising to passengers. When people book their cruise with us, we calculate the emissions their cruise would generate, and plant Australian native trees to offset the emissions at no extra cost. The site has been soft-launched and we have an existing logo and tagline but want to see some fresh ideas. We think an icon that combines a cruise ship and green theme could work well, ie trees replacing the smokestacks or something. Thanks in advance.
