I want to know the answer to the following question:
When did the ITU announce that it had embraced micro-USB as the Universal Charging Solution?
All the background I'm provided with is that "In addition, on 22 October 2009 the International Telecommunication Union (ITU) has also announced that it had embraced micro-USB as the Universal Charging Solution its "energy-efficient one-charger-fits-all new mobile phone solution," and added: "Based on the Micro-USB interface, UCS chargers also include a 4-star or higher efficiency rating—​​up to three times more energy-efficient than an unrated charger."". Is that enough to answer the question?
Answer: yes
