What is unique about green innovation? Evidence from green hydrogen, green steel, batteries and electric vehicles

Green hydrogen, green steel, batteries, and electric vehicles (EVs) are critical examples of green transition efforts in heavy industry, transport, and energy, spanning upstream sectors (green hydrogen and batteries) and downstream sectors (green steel and EVs). In 2019, global GHG emissions were largely driven by heavy industry, energy, and transport, contributing 24%, 23%, and 15% of total emissions, respectively (IPCC, […]
