Cover Story
Policy Challenges for Achieving Carbon Neutrality
Increasingly, the efforts to address global warming are seen, not as a burden, but as an opportunity to create new business models and transform the industrial structure. Hiroshi Ohashi, Vice President and Professor of Economics at the University of Tokyo, discusses the measures to promote investment in GX that are prerequisites for carbon pricing.
Rethinking Current Practices to Enable a Sustainable Future
Many countries and regions have declared their intention to reach carbon neutrality by 2050. What are the key considerations when it comes to achieving carbon neutrality? Also, as an island nation in Europe, what is the UK doing? Hitachi Review posed these questions to Professor Mary Ryan, Vice-Provost of Imperial College London.
Helping Fleets Achieve Accelerated Electrification
Optimise Prime Initiative in the UK
Over the last four years, Hitachi and Optimise Prime have gathered data on the usage of commercial EVs, exploring new methods for reducing impact on electricity infrastructure. The data gathered will help power networks and local authorities plan to meet future EV charging demands. This article provides the project findings and the future outlook.
Achieving Carbon Neutrality in 2050
Policies and Technologies Needed for GX
The impact of climate change on people’s lives and corporate activity is becoming significant, efforts are required both to address climate change and ensure security and to stabilize energy supplies. Hitachi Review invited two experts to share their visions for decarbonization and to discuss specific measures for promoting and implementing GX.
