1. This statement is false.
2. This statement is true.
3. This statement is partially true.
4. This statement is misleading.

Correct answer: This statement is false.

Solution

The statement is false because CFCs are ozone-depleting substances, not the main greenhouse gases typically discussed in climate totals. The claim that the United States emits about 37% of them is also not a standard or accurate attribution.
