Achieving net zero will be the biggest technological challenge of the 21st century
The COP26 summit illustrates how the agenda has shifted from recognition to targets, with particular targets set for achieving net zero CO2 emissions
Look at almost any annual report from a listed company and the first dozen pages are full of references to sustainability and assessments of current climate/CO2 impact—large companies are not waiting for 2035
Summary
Achieving net zero will be the biggest technological challenge of the 21st century. A truly global, all-pervasive challenge impacting every application, market, and technology. A random sample of annual reports of firms associated with the photonics industry shows a 7-fold increase in terms associated with sustainability (climate, energy etc) between 2016 and 2020.
