What are these “green talents” that are attracting attention? Background to the $5 Trillion-Plus GX Market According to the International Renewable Energy Agency’s (IRENA) “World Energy Transitions Outlook 2023,” achieving the 1.5°C target (the Paris Agreement’s goal of limiting global temperature rise to 1.5°C) will require cumulative GX investment of $150 trillion (approximately 2 quadrillion yen) by 2050, translating into an annual average of more than $5 trillion (approximately 700 trillion yen). Furthermore, in 2020, the Japanese government officially declared its intention to achieve carbon neutrality by 2050. The GX Promotion Act will be enacted in 2023, and it is expected that over the next 10 years, GX investments of over 150 trillion yen will begin in earnest. In the expanding GX business market, you have the potential to dramatically increase your market value. ■Points of this book 1.

Includes conversations with key figures in green risk-skilling both in Japan and overseas Shuichiro Kawamura (President and CEO, Energy & Environment Investment Co., Ltd.) Anshuman Bapna (Terra.do Inc.) CEO) Hiroyuki Nagashima (Managing Partner, Toy Toy LLC / Visiting Researcher, Chuo University Corporate Research Institute) Midori Mizobe (Senior Manager, CIC Institute) Hiroaki Idema (Senior Advisor, Green Talent Hub Co., Ltd. / Business Creation Division, Tohoku Electric Power Co., Inc.) Advisor) Message from the Author Many people think that the field of decarbonization is highly specialized and has nothing to do with them, but that’s a misunderstanding. Green talent isn’t someone with a wealth of knowledge, or someone with a fancy title. It’s someone who is excited about change and who can continue to learn and improve themselves. Your past experience is more valuable than you might think. This book is packed with concrete ways to bridge that value to the “future era” of climate change. Career sustainability is not guaranteed by companies or systems. The future is up to you, and no one else. I sincerely hope this book will be a reliable guidebook that encourages readers to take their next step. ■Book summary Title: Author: Kazuhiro Iguchi (CEO, Green Talent Hub) Release Date: Friday, August 29, 2025 Format: A5 size / Paperback / 264 pages Price: 1,980 yen (tax included) ISBN: 978-4-485-30127-2 / C0034 Publisher: Denki Shoin Co., Ltd.
