How the Planetary Diet Could Slash Emissions and Save Lives

The global food system produces nearly a third of all human-caused greenhouse gas emissions. Experts have developed the planetary diet, also known as the EAT-Lancet diet, to address this issue while improving health. The plan encourages a shift towards plant-based foods with limited animal products. The planetary diet was designed to feed a growing population sustainably. It promotes diverse plant-based meals with smaller amounts of fish, eggs, and dairy. Red meat and dairy are currently among the biggest contributors to dietary emissions.

Adopting this diet could reduce global emissions by 17%. In some countries, like Uzbekistan, Australia, and Qatar, the drop could exceed 60%. For populations that overconsume, emissions might fall by 32.4%.

Health benefits are also significant. The diet aims to cut saturated fat and sugar intake, lowering the risk of premature death by 30%. However, cost remains a barrier, as 1.58 billion people worldwide cannot afford it. The planetary diet offers a way to reduce environmental harm and improve health. Its widespread adoption could lead to substantial cuts in emissions and better nutrition. Yet, affordability remains a major challenge for many.
