On this issue, Earth system scientist Johan Rockström, Director of the Potsdam Institute for Climate Impact Research:
“The science is clear, the world needs to reach net-zero emissions by 2050 to stand a chance of holding the Paris limit of keeping global warming well-below 2°C. The EU is the world's climate leader, and that it commits in the upcoming Climate Law the target of reaching net-zero by 2050 is positive, and will certainly influence countries and actors around the world that either have taken similar steps – like China, Japan and soon the US –, or that need to do so. The EU pledge of carbon neutrality by 2050 requires large transformative changes, with overall emissions reducing by some 6% per year. This will require large innovations, behavioral change, restructuring sectors and supply chains. Given that evidence increasingly shows that zero-carbon development is beneficial for the economy, jobs, health and resilience, there is a chance that the EU may exceed its own pledges. This will very likely be necessary.”
