Venting R600A (isobutane) isn't really the problem. This stuff gets vented from things like backpacking stoves fairly regularly. R410A is what's used in most modern HVAC equipment and it has a GWP of around 4000 (it's complicated because it's a mix of two refrigerants). 3000g of R410A might be in a small to moderate-sized system.
