Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_73732 ( "Country" text, "Annual CO2 emissions (in thousands of metric tons)" real, "GDP (current, in billions of US dollars)" text, "GDP per Emissions (in US dollars per ton)" real, "GDP (PPP, in billions of current international dollars)" text, "PPP GDP per Emissions (in international dollars per ton)" real )

### Question ###
when the gdp (current, in billions of us dollars) is 162.50, what is the GDP?

### Accurate SQL ###

SELECT MAX("GDP per Emissions (in US dollars per ton)") FROM table_73732 WHERE "GDP (current, in billions of US dollars)" = '162.50'
