What happened

New ammonia-making method could upend one of industry's dirtiest processes Stephanie Baum Scientific Editor Robert Egan Associate Editor As our world's population grows, so does the demand for ammonia—a key ingredient in fertilizer.

Why it matters

The International Renewable Energy Agency estimates that ammonia production must quadruple by 2050 to feed the increase in global population.

Common ground

The current gold standard process for producing ammonia is energy-intensive and a major contributor to global greenhouse gas emissions.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
