After the Paris Climate agreement of 2015, the President and Chief Executive Officer of Yara shifted gears. The milestone event - held just a few months after he started at Yara - sharpened his understanding of the critical role his company could play in decarbonising food value chains. This shifts that resulted have meant new priorities and a new way of working for him and his teams at the fertiliser and food solutions company. It has also lead to an exploration of innovations such as green ammonia that could lead to fossil free solutions for fertiliser and fuel. Such new solutions require collaboration and trust. That trust, says Holsether, will be play a bigger role than miracle tech in making progress for the climate.
