There are a wide range of sustainability topics that have an impact on the built environment and related industries. Starting with sustainability tension and the impact on organisational behaviour and finishing with ESG data, technology and green finance. The changing landscape results from growing emphasis on sustainability whether it is top down or bottom up.
