President Macron said he would visit Budapest in the first half of 2018, reported MTI. 

Áder told MTI the two presidents had discussed implementation of the Paris Treaty climate agreement, drafted in 2015, agreeing that the accord should be extended to subnational actors such as regions and towns, and that EU carbon prices should be raised from the current EUR 8 per tonne to around EUR 25-30 per tonne. 

Both Áder and Macron said nuclear power capacities are needed until a solution is found to the problem of storing energy.
