Hydrogen is feted as the key to a dynamic green economy. But is it the best choice for decarbonisation in all cases?
Don't count nuclear energy out – it may be our best hope of reaching net-zero emissions within the time we have left.
A precedent set at the industry's outset has dominated efforts to reform aviation.
Low-carbon energy sources aren't all equally well-suited to getting us to net-zero emissions.
New bike lanes are a good idea for health and air quality, but the convenience of car travel for most journeys will remain.
It seems likely we are going to need radical reductions in future ownership of private vehicles as we transition to cleaner transport.
Energy efficiency and electrification should lead the effort to decarbonise society, not hydrogen.
Building a greener economy starts at home.
Emissions from Australia's electricity sector have dropped markedly during the pandemic.
