Not in parallel—follow ARR/conference dual-submission rules.

Compare

Layouts are cousins. Differences are community and live tracks—not one-column vs two-column.

Facet	ACL	EMNLP
Body pages (typical)	Long 8 / short 4	Long 8 / short 4
Review path	Usually ARR → commit	Usually ARR → commit
Limitations	Required, uncounted	Required, uncounted
Community fit	Flagship CL, broader scope	Empirical NLP, eval, resources
Template	Official *ACL two-column	Official *ACL/EMNLP two-column

Lean ACL for broader CL; EMNLP for methods, evaluation, and resources. Use that year’s official *ACL pack and check commit deadlines.
