Technology Transformation - Consumer Products & Retail
Digitalisation has transformed how consumer products are manufactured, distributed and sold.The push to maintain a competitive advantage, drives increased investment in new technologies. This investment may reduce operational cost and ease the retention of legacy systems, but what challenges arise and how do businesses approach the changing risk profile?This report is a deep dive into data first produced for the re­port Tech­no­logy Transformation: Managing Risks in a Changing Landscape. In the original report we surveyed over 500 corporate counsel and risk managers from multiple industries across the world.Here, we look in detail at the 75 respondents surveyed in the consumer and retail sector, and their perspectives on the risks associated with busi­ness-crit­ic­al technologies, including emerging technologies. Our survey shows that businesses across the sector, whether retailers or manufacturers, have the same concerns but the influences on the adoption of technology, the resulting risks, and the approaches taken to mitigate or resolve those risks vary depending on whether or not the business involves a direct sales relationship with the con­sumer.Down­load the consumer and retail sector report now to read about: Drivers of technology adoption in the consumer and retail sectorNew risks emerging and traditional barriers to risk man­age­ment­Cur­rent technology risks in the consumer and retail sectorFuture risks and measures to deal with themPreferred approaches to technology dispute resolution for the consumer and retail sector

Digital Assets
Does your business have or is it ready for digitalisation and digital assets? Digital assets are transforming the world of business. Not just technologies in the news, like AI and crypto currencies, but a whole world of technological advances, from digital twins and extended reality to smart contracts and token­isa­tion. For tech businesses and those already using such technology to develop and market new products, much of this is core activity and relatively well understood – although legal and regulatory uncertainties remain, and potential pitfalls still exist for the unwary.But other business leaders, often less familiar with the territory, have to manage an increasingly complex assortment of issues that never troubled their predecessors, ranging from protecting their brand in the metaverse to deciding whether they should tokenise their shares or accept payments in crypto currencies.This section of Bandwidth looks at issues around the development and regulation of a wide variety of digital assets, and discusses how businesses can embrace them to innovate and evolve.

MEES - why are local authorities failing to enforce?
The UK government has a continued drive and commitment to reach net zero emissions by 2050. Yet as highlighted in the first of this series of publications, “MEES – are the regulations working?” the risk of MEES enforcement is low. Against a hotly discussed political backdrop, why is it that local authorities are continually failing to enforce the MEES regulations? Left alone, the existing approach serves to undermine the UK’s net zero strategy.
