At this point I don't think the targets will be met. Replacing all those boilers will be very unpopular, it will require a huge amount more electrical capacity and infrastructure alone. It's also very unlikely any new nuclear power will be available by 2035 the first target date. Spending the same money/political capital on cutting cars or flights or renewables would get a lot more co2e reduction a lot faster...
