It was crucial to collaborate with the International Cleantech Network in our search for 1,000 Efficient Solutions; we needed that partnership to increase the quality and geographical diversity of the portfolio. Now that this scouting objective has been reached, we foresee teaming up with ICN to anchor our Foundation’s advocacy and implementation actions in the reality of challenges on the ground. I am looking forward to continuing leveraging that strong partnership to boost the adoption of cleantech.
