In recent decades the climate emergency has become increasingly urgent and heartfelt. Governments, driven by social pressure, have begun to plan interventions to reduce the impact on their countries' economies. Following these initiatives numerous companies have moved to reduce their environmental impact. Seeking to achieve these ambitious results, companies are relying heavily on innovation and the development of new technologies.

Taking over to support this new market is blockchain technology.
