But wait a minute: of course, all studies should take all issues into account (they never do) That’s why you use a meta-study (all papers leave out something, but taking them together eliminates cherry-picking)

3) They cite Swedish study’s very honest description of limitations to estimates of CO₂e reduction from going vegetarian“ (similar arguments would apply to all the studies in metastudy) But again, this has *nothing* to do with rebound

Indeed, the Swedish study explicitly shows how *any* realistic modeling of rebound means a diminishment of the reduction from going vegetarian. My critics simply chose to ignore this

Ironically, my critics’ favorite article, Hoolohan, explicitly backs up the rebound point: Instead of the Swedish finding that going vegetarian reduces costs by 1.89%, Hoolohan finds it reduces costs by 3%, allowing for 3% other purchasespic.twitter.com/0dDgFZajJM

The rebound effect of 3% more spending on everything else is estimated by assuming proportional spending on all other products (Swedish article shows this is likely a slight underestimate), approximately 373kgCO₂e (=3%*12440)

So their own, favorite article indicates a *higher* rebound effect than what I show But despite a lot of verbiage, they simply ignore the rebound effect

tl;dr: Going vegetarian cuts your greenhouse emissions ~2% Critics cherry-pick studies and ignore economics, hence exaggerate impact of going vegetarian about 5xpic.twitter.com/ZMwadmWy24

Addendum: This discussion question of likely size of impact – unlikely 2.1% exactly correct answer. But based on best estimate from meta-study along with best estimate for rebound Picking the absolutely highest number and ignoring rebound is extremely likely to be exaggerated
