The target page is a bit more complex: first you need to switch to iframe and next to frame:

driver.get('http://estatisticas.cetip.com.br/astec/series_v05/paginas/lum_web_v05_series_introducao.asp?str_Modulo=Ativo&int_Idioma=1&int_Titulo=6&int_NivelBD=2/')
driver.find_element_by_xpath('//*[@id="divContainerIframeBmf"]/div/dl/dd[2]/a').click()
driver.switch_to.frame(driver.find_element(By.XPATH, '//iframe[@name="dados_corpo"]'))
driver.switch_to.frame(driver.find_element(By.XPATH, '//frame[@name="ativo"]'))
find_dp1 = driver.find_element(By.XPATH, '//select[@name="ativo"]')
select_find_dp1 = Select(find_dp1)
select_find_dp1.select_by_visible_text("CBIO - Crédito de descarbonização")

time.sleep(3)
