Both of the major American political parties are hard to categorize with one or two Words, although many try. There are "liberals" and "conservatives" in both parties. More liberals are in the Democratic Party and more conservatives are in the Republican Party but that is not the entire story.

The American Republican Party continues to hold among its members people who believe in being "conservative" with natural resources. The Environmental Protection Agency was created under a Republican President.
