See Get default login environment and the discussion therein. There is Shell::EnvImporter.

I'm not sure if you really want the effects of a shell script, or just something that "looks like sh environment commands". If so, your approach seems good, but doesn't respect quoted constructs.

In your code, I would at least change the split() to a more robust parser, so that it also understands foo=bar=baz as setting foo to bar=baz:

       #my ($key, $value) = split /\s*=\s*/, $line;
       if( $line =~ /^\s*([^=]+)=(.*?)\s*$/ ) {
           my ($key,$value) = ($1,$2);
           $ENV{$key} = $value;
       } else {
           croak "Malformed environment line: '$line'";
       };

Support for foo="bar=baz" and foo=\"bar=baz\" would also be addable, but if you want to support multiline values, you'll have to switch away from line-based parsing.

Updated: The capturing parentheses were missing for the key, spotted by Anomalous Monk
