Establish new technology hub in Germany in 2023
to foster advanced development for Carbon Neutrality / Circular Economy“Regenerative” refers to initiatives that aim to achieve positive impact, contribute to, and enhance
the global environment and society. In an era marked by indisputable climate change and depletion ofnatural resources, the term “regenerative” is gaining prominence as a proactive approach thattranscends the neutral connotation of the term “sustainable.” Instead, it fundamentally advocates acomprehensive approach to realizing its goals, encompassing both nature and social systems.
