The French President urged “new ambition” or the Brussels bloc would face the “dismantling of Europe”.
It comes after European Commission President Mr Juncker’s State of the Union speech which included his masterplan for greater integration without treaty change.
But speaking at a Bloomberg event in New York, Mr Macron warned of difficult months and years ahead for the bloc if it could not shake its image of overbearing bureaucracy.
He said: “We have to fix 10 years’ objectives for Europe and we have to decide some convergences and some investment decisions in order to reach these objectives.
“We will have to change treaties but we need these new ambitions because for my generation there is just one alternative.

“Do we want the dismantling of Europe and it’s an ongoing process, we discussed years and years about Brexit and now it’s all about Brexit and now we have a lot of tensions with Poland regarding overflow in Europe.
“But in a few months or years, you will have other countries suddenly raising and saying ‘I’m no longer comfortable with this bureaucracy and with this Europe without any vision, but just a lot of constraints’.”
In his State of the Union address last week, Mr Juncker ratcheted-up the federalisation of the 60-year-old bloc’s core economies.
The Brussels boss has also called for EU integration in the face of rising populism after Britain voted to sever ties with the bloc ahead of crunch elections in Italy, Sweden, Hungary and the Czech Republic, where eurosceptic parties are gaining momentum.
It appears the EU chief is keen to make his mark with a grand masterplan to rebuild the bloc, as his five-year term as European Commission president expires in 2019.
