Carbon Positive Logo

C'est ce que Carbon Positive "Creating a positive future for NZ businesses" recherchait dans leur logo design

I need a logo designed for a New Zealand based company that provides tools enable businesses to measure their carbon dioxide footprint, identify greenhouse gas (GHG) reductions, and offset GHG emissions through planting trees.
The logo should incorporate greens or blues and a link in the logo to the name being 'positive' or incorporation of a tree element . Our measurement is an annual cycle so open to circles in the logo if desired. Please see samples attached of the colours and symbols we like - happy for designs to be similar to the concepts in the samples Voir plus
