Between 40 to 50% of our population is alive on this planet today thanks to fertilizers. However, fertilizers are also one of the largest greenhouse gas emitters and when managed poorly, can also contribute to the nutrient pollution of lakes, rivers and streams.  This week, we sat down with Pablo Barrera Lopez, Executive Vice President of Strategy and Communications at Yara International, a leading Norwegian agribusiness and chemical company on the forefront of the sustainable and ethical production of several types of fertilizer. Lopez takes us through the history of the fertilizer industry (hint, modern fertilizers were invented at Yara), how the invention of fertilizer prevented mass hunger, and the complicated relationship of the life-saving product with climate change. Lopez also walks us through the top innovations taking place in the industry to mitigate its impact on climate including everything from renewable-energy fueled fertilizer plants and high-tech precision application tools to better farmer education. In addition, Lopez works with the World Economic Forum, where he promotes corporate sustainability and works with global youth to help them develop talents and skills to be responsible forces for good in their communities.
