This report examines how the climate impact of electricity use is shaped not just by its source, but also by its timing and location. It evaluates the EU’s RED III framework and associated hydrogen targets, using the RFNBO standard as a case study. The analysis shows that ill-timed use of renewable electricity (particularly for hydrogen production) can inadvertently drive fossil generation. It argues for more strategic use of electricity to avoid these unintended consequences and support genuine decarbonisation.
