As I see it the change is all too slow. There has been a plethora of commitments by sovereign states over the past 15 years or so, none of which even come close to having any real impact on tackling climate change. We have yet to come up with a formula as to how the polluting countries are going to split up the dwindling carbon budget while 'decarbonising'. As around 87% of global primary energy is from fossil fuel we will be emitting considerable amounts of CO2 while providing alternatives to replace it. And if I understand the IPCC figures it will be all too late if by 2030 if Europe's renewable capacity is only 27%
