Paolo Gemma – senior Specialist for Europe and representative of Huawei on issues related to energy saving and environmental sustainability of companies worldwide – has done its input in Huawei in April 2008.

Before he was in Nokia Siemens Networks, has been responsible for laboratories Italian for EMC (electromagnetic compatibility) and electrical safety areas. Previously he held for 18 years a role like within the Siemens Communications Division. Paolo Gemma, between the leading experts of sector at international level, has an active role in international standardization activities. Since 1993 has engaged in ETSI (European Telecommunication Standard Institute) and participates in the development of telecommunications EMC standards.

In 1997 he joined ITU-T Study Group 5 as Rapporteur and he is now the Chairman of Working Party 3 “ICT and Climate Change”. Paolo Gemma has followed the work of the EE (Environmental Engineering) of ETSI Technical Committee since 1998. EE is the Technical Committee of ETSI engaged in the standardization of energy power, mechanics and environmental conditions. The group is committed since 2004 on ecological issues in particular with regard to the reduction of energy consumption and cooling management of equipment and installation publishing some standards on this issue. In 2002, has been appointed Secretary of the Committee ETSI TC EE and 2009 holds the position of Chairman of the EEPS EE (eco Environmental product standard) working group.

Tim Smolcic is a global technology executive and a leading voice in sustainable IT, with over 15 years of experience driving innovation at the intersection of enterprise technology, cloud computing, AI, and environmental impact. Currently serving as Director of IT Strategy & Sustainability at HSBC, Tim leads global transformation initiatives, integrating sustainability as a core design principle for modern enterprise infrastructure.

A passionate advocate for responsible technology, Tim is an active partner of the ITU Green Digital Action initiative. His work focuses on embedding sustainability into the digital ecosystem—particularly the development of open-source tools that enable real-time measurement of software-related carbon emissions. His patented carbon tracking framework is now listed on the UN Digital Public Goods Register.

At the AI for Good Summit, Tim brings industry-wide insights from his ongoing research into the measurement and reporting of AI energy consumption. His work identifies critical gaps in current methodologies and reporting frameworks, offering evidence-based recommendations to align AI development with global sustainability goals. Through cross-sector collaboration, Tim is helping define what “green AI” means in practice—and where the industry must evolve to close the disconnect between innovation and environmental accountability.
