This is discussed in the article:
"Some scientists have suggested that grass-finished beef, if managed properly, can be a more sustainable option: As the cattle graze, they stimulate grass to grow deep roots and pull more carbon into the soil, helping to offset the cows’ climate impact. But, on the flip side, grass-finished cattle also take longer to reach slaughter weight, which means they spend more time burping up methane into the atmosphere. Because of this, some studies have suggested that grass-fed beef can actually be worse for the climate over all, though the debate about this continues to rage.
For now, it’s hard to say with confidence that grass-fed beef is consistently more climate-friendly than conventional beef."
