The UAE ranked 14th for the highest national concentration of sustainable buildings in the world and was the only country from the region in the top 30, according to a new survey. The country is home to 869 green-rated buildings, while Saudi Arabia ranked 54th with 38 green-rated buildings, consultancy Knight Frank said in the second edition of its (Y)our Space report, which surveyed almost 400 businesses worldwide on their workplace strategies and real estate needs. Kuwait and Oman have 12 green-accredited buildings each and rank 69th and 70th, respectively. "The climate crisis has spawned a global green reawakening and businesses in the Middle East are alive to the climate challenge," Faisal Durrani, head of Middle East research at Knight Frank, said. The UAE is encouraging the construction of greener buildings and working to retrofit older buildings to make them less energy-intensive as part of its push into energy sustainability. The UAE has committed to the Paris Agreement on climate change to reduce its greenhouse gas emissions by 23.5 per cent by 2030. Global companies that have set a 2030 net zero carbon target may struggle to achieve their objectives if there is no major shift towards sustainable buildings, the Knight Frank report found Three-quarters of Middle East businesses surveyed, which represent 7,800 staff, say their real estate choices in the future will be influenced by their net zero targets, the consultancy said. However, the vast majority of companies say that less than 25 per cent of their global portfolios are green or sustainable. “The message to landlords is loud and clear: green credentials of buildings will become a key battleground in [the] post-Covid economy, particularly as office footprints are likely to be revised downward as more businesses adopt hybrid working methods, factoring for greater remote working," Mr Durrani said. Being "greener" will be a major differentiator as businesses adapt their occupational strategies to encourage more employees to return to the office, he added. Landlords in the region will have to weigh the costs and benefits of "greenifying" their buildings to cater to changing business demands. "As investors and businesses are increasingly factoring the green credentials of a building in their decision making, it’s clear that the saleability and lettability of non-green-rated buildings will be negatively impacted over the medium to long-term," Mr Durrani said. Global businesses want to be more sustainable, with 40 per cent of companies setting a net zero carbon target, the report showed. Of those, 77 per cent are aiming to achieve this goal by 2030. However, despite the real estate sector accounting for as much as 40 per cent of global carbon emissions, and with growing pressure from the environmental, social and governance (ESG) agendas of investors, more than 87 per cent of companies said that less than half of their current global real estate portfolios are either green or sustainable, the report said. "This suggests a real disconnect between real estate and wider corporate thinking on sustainability," Knight Frank said. Almost 60 per cent of global respondents said that there is only a partial recognition from their wider business that occupying and utilising real estate differently will impact their ability to achieve net zero carbon and wider sustainability targets. A further 15 per cent said that there is no recognition of this at all, the report showed. “Developers and landlords in the Middle East have made great strides in delivering world-leading green buildings, incorporating stunning technologies," Mr Durrani said, citing the condensation harvesting system on the Burj Khalifa as an example. "But such technologies need to be adopted more widely if landlords are to compete on a level playing field for increasingly green conscious businesses," he added.
