Reducing usage of technology can increase emissions through secondary factors. It's a major inconvenience with a minor or even sometimes negative gain (real life activities like driving are more co2 intensive).

Reducing meat consumption doesn't increase emissions because animals already have to eat plants and they already fart on our behalf. If you cut out the middleman (the animal) you need less plants and also fart less. It's a major inconvenience with a major gain.
