Local governments are on the front lines of climate resilience, yet they are often the least resourced to manage critical infrastructure. In this episode, Rory Linehan, director of infrastructure policy advancement at Bentley Systems, joins us to discuss how technology is levelling the playing field. Linehan reveals practical ways regional leaders can safeguard assets, reduce long-term costs, and make informed planning decisions without requiring massive capital budgets or complex technical expertise to build enduring, climate-ready communities.

Jess Miller on lazy spaces, Town Square and the new green challenge

Halfway through her second term as Deputy Lord Mayor of Sydney Jess Miller, who will take to the stage at our next Big Debate, Carbon Triggers, has wasted no time in tackling the glaring problems that annoy her and many others. Among them are the “lazy” or empty spaces in many of the city’s commercial buildings, the housing that’s given over to short term/Airbnb style accommodation and the loss of places for arts and creative work.

Kaushik Chakraborty on trends on infrastructure

Infrastructure work is going regional – in water, sanitation, roads and bridges – says Kaushik Chakraborty senior vice president, Asia Pacific & Japan with Bentley Systems in this podcast.
