Stupid little question, but how this:

It was essential, he said, that “France reduces our dependence on so-called fossil fuels, coal, petrol and gas, which we don’t produce any more but on which we depend”. The aim, he added, was to reduce this dependence from 60% to 40% by 2030.

The same as no fossil fuels by 2030. If you are 40% dependent on fossil fuels by 2030, you are still using fossil fuels or am I somehow mistaken.

I am guessing it is no fossil fuels in the electricity grid by 2030, but that is just a guess.
