The 3 arrows stand for development and strategy. The orange arrow symbolizes Global Warming, the blue arrow stands for business and economy, the green arrow symbolizes alternative/ green energy sources.
Again the three arrows symbolizing Global Warming, Economy/ Business and Green Energy. Arrows pointing up symbolize growth, the arrow that points down symbolizes a decline.
Hi there! Thank you for participating! For numbers 3 and 4: Sorry requires too much explanation. Logo should stand by its own merit. Not exciting enough. Cheers!
