You would emit more CO2 switching to glass than you would save. It's not worth it.
Glass is heavy, breakable, and not worth recycling (the planet's crust is made of glass so there's no real reason to recycle it, the glass shards harm the recycling of everything else, and the weight consumes extra energy in transport.)
And yes, you could make plastic directly out of air. And you can recycle the plastic back into air by burning it. It's a very clean process.
