Queensland, Dec 20: As international air travel rebounds after COVID-19 restrictions, greenhouse gas emissions from aviation are expected to rise dramatically – and with it, scrutiny of the industry’s environmental credentials. Aviation emissions have almost doubled since 2000 and in 2018 reached one billion tonnes. Climate Action Tracker rates the industry’s climate performance as critically insufficient. As the climate change threat rapidly worsens, can aviation make the transition to a low-carbon future – and perhaps even reach net-zero emissions? The […]

Commercial flights could one day be propelled by sustainable fuels, renewable energy or hydrogen propulsion – but big challenges remain.

If current climate targets are met there will likely be a 50% increase in droughts in the Middle East by 2050 compared to a 2C rise in global temperatur

That will likely bring price shocks associated with rising metal prices, energy costs, and carbon taxes – what has been called “greenflation”. Greening the economy will also require public spending and redistributive policies.
