Apple has become more environmentally-friendly over the years not only by how they run their business, from relying on renewable energy to using environmentally-friendly packaging, but also by how they design their products. Apple Silicon not only empowers users with greater performance and battery life, but also reduces electricity usage in every computer that uses it. If automotive emissions regulations were applied to Apple products, they would pass with flying colors because of how little electricity they use. In fact, "In 2022, all eligible Apple devices received an ENERGY STAR® rating for superior energy efficiency."
In light of Apple's pursuit of environmentally-friendly products, iMacs don't make good sense. An iMac becomes e-waste as soon as a customer is dissatisfied with its screen or performance, while a separate Mac mini and display may be replaced independently of each other.
In the past, buying a large-screen iMac was necessary if you wanted an affordable but fast Mac with a big screen. Back then, the Mac Pro was too expensive, and the Mac mini was underpowered. Today's Mac mini can now be had with an M2 Pro processor, and all you need to do is pair it with a third-party screen that's larger than the largest iMac ever sold (27 inches). Customers are spoiled for choice nowadays, and don't need the large iMac anymore.
