I'd first question whether the NY Times' accounting included the carbon footprint within NZ, where the lambs are probably raised far from the shipping piers. Then you've got the infrastructure and power requirements for freezing for the long ocean voyage. Then...

After that, I'd question local sheep farmers about how suitable upstate NY is for raising lambs, compared to NZ. And about the regulatory and business environment they face. Agriculture in the US is a hellish mess, and the great majority of its problems are caused by neither its associated carbon emissions nor by underinvesting in transportation infrastructure.
