Just by virtue of them being big, it is still a problem. Also said started goal is less than used for consensus "current" climate change target by IPCC which is considered optimistic and nets some 3.5 C rise as per model.

2050 is too late as well. To make a big difference the timetable for that capacity would have to be 2030 and all the baseline would have to be hydro or nuclear. This is unlikely to happen even if they really want to do it.

Now consider that we also have USA to handle who are notorious about ignoring climate change targets...

Now, even 5 C is not a cataclysmic event but it will be very bad on a global scale - mostly water availability and farming, related price shocks and social upheaval.
