A mere 100 years ago pretty much everything that was for sale, food, clothes, tennis rackets, condoms (or what passed for one), ... was produced from animals.
You'd have to stop doing a hell of a lot more than merely stop eating meat to have any measurable impact.
Also what about the secondary effect ? If you stop eating meat, that will increase supply and reduce demand, and thus drop the price by a lot, which will lead to new customers, both for eating and other applications.
You really want to help ? Buy the rainforest, let it be rainforest. For bonus points, destroy the co2 certificates instead of selling them.
You would also have to protect the rainforest. There was a documentary about a guy who did this (https://www.youtube.com/watch?v=eKFJjkRZk6Q). And he had to spend a great deal of time (and flights) to try and stop people poaching the wood.
Another free market solution (well, kind of), is for the price of CO₂ to rise enough so it may be economically feasible to "buy the rainforest [to] let it be rainforest". This also should of course come with some mean of allotting taxed resources to the CO₂ consumers.

Things just aren't this simple.
