Climate change is evolving as the major concern of erratic weather conditions for example heavy rains, drought floods, landslides, soil erosion, tsunami, and extreme cold and warm weather, which severely impact the livelihoods of mankind. Attaining the substance by reducing carbon pollution and other greenhouse gases is the best way to control climate change. Considering the suitable climate, habitat variation, and their adverse effects such as glaciers, heatwave, sea levels rise, etc., it is important to understand the climate control and framing combat policy as per the requirement of energy. Hydrogen is now established as a clean and flexible energy carrier. Europe and the other nations are progressively walking toward achieving the net-zero objective with the overview of clean hydrogen energy, which will ensure global sustainability faster.
