c = conn.cursor()

c.execute('''CREATE TABLE unfccc (
        Country TEXT, 
        CodeCountryFormat TEXT,

def insert_row(Country, CodeCountryFormat, NamePollutant, NameYearSector, NameParent, Sector, CodeSector, CNUEDSPD):
    c.execute("INSERT INTO unfccc VALUES (?, ?, ?, ?, ?, ?, ?, ?)", (Country, CodeCountryFormat, NamePollutant, NameYearSector, NameParent, Sector, CodeSector, CNUEDSPD))
    conn.commit()

with open('UNFCCC_v20.csv') as csvfile:
    readCSV = csv.reader(csvfile, delimiter='\t')

    counter = 0

    for row in readCSV:
        insert_row(row[0], row[1], row[2], …
