Yes, sh's builtin "env" does this.

It seems you're mixing shells here. The C Shell uses setenv
to set variables, printenv to list them. The systems's sh
uses export to set variables, and env to print them.

Example (with exported and non-exported variable:

	$ export ASDF=yxcvbnm
	$ env | grep ASDF
	ASDF=yxcvbnm

	$ JKL=qwertzuiop
	$ env | grep JKL
	$ echo $JKL
	qwertzuiop

And compare for the C shell:

	% setenv ASDF yxcvbnm
	% printenv | grep ASDF
	ASDF=yxcvbnm

	% set JKL=qwertzuiop
	% printenv | grep JKL
	% echo $JKL
	qwertzuiop

If you omit the "| grep" step, the full list will be printed.
