Reducing meat intake and replacing it with veggies where you can does heaps for the environment. Your best is phenomenal, if everyone did your best, I bet the industries would adapt and offer more alternatives you aren't allergic to, so you had more choice to evolve what "your best" is.

Sadly this is probably going to be a generational change, multi generational even, so please don't chastise yourself for not being able to do more.

Me for example, I try to use vegan/vegetarian ingredients where I can but I'm lazy and also eat meat every 2-3 days. The moment I learn of a new lazy healthy product that tastes good I introduce it to my diet, it's a slow process lol.

I genuinely think this is one of the few good reasons not to be fully vegan. Props to you for still doing your best despite how frustrating all those allergies must be.

From a climate/environmental perspective, just reducing or eliminating beef makes the most impact. Chicken and fish use far less resources and far fewer emissions per lb.

Thanks for wanting to help out :)

I used to be allergic to soy and most fruits 20 years ago. Thankfully that calmed down and went away with most things.
