One more lane won't fix Britain's congested motorways.
History shows how the states and territories can step into a policy breach when the federal government fails. It's time they band together on electric vehicles.
Green hydrogen produced using New Zealand's mostly renewable electricity sounds like a great idea, but a high-tech smart rail and urban tram network is a more obvious and sustainable option.
A new Morrison government plan sorely misses the point on electric vehicles. It's in stark contrast to Biden's ambitious EV strategy.
Australia has a lot of work to do to overcome the challenges facing electric vehicles users, starting with the lack of a comprehensive national charging network.
A net-zero goal will provide clarity, ambition and focus. But Morrison must back the rhetoric with investment and policy commensurate with the task.
The Climate Change Commission releases New Zealand's first comprehensive plan to cut emissions, calling on the government to "pick up the pace".
Exaggerating how much lockdown improved air quality could allow us to underestimate the scale of the air pollution problem.
A person who exercises, attends sporting events as a spectator and takes their kids to the oval or swimming pool will create 935 kg of CO₂ per year if using their car.
Electric vehicles would lower emissions, but if their lower running costs lead to increased car use that creates a whole lot of other costs for our cities.
It's high time the international shipping industry radically curbed its emissions. The industry must set a net-zero target and adopt a realistic plan to meet it.
Some atmospheric pollutants actually help cool the planet, but the sudden shutdown of heavy industry threatened to purge them.
Australian bicycles are largely influenced by sport, not utility. We should embrace cargo bikes for their usefulness, over speed.

New Zealand voters are divided on climate policy along party lines, with the majority on one side of the political spectrum calling for urgent action while at the other end most recommend caution.
Without plastic shielding between seats or more efficient engines, the environmental benefits of public transport are lost.
The drop in traffic during COVID-19 lockdowns reduced global emissions. If we keep encouraging cycling and working from home beyond the pandemic, our climate goals may become more achievable.
Removing engine idling would be like removing up to 1.6 million cars from the road.
Bullet trains are back on the agenda. But a new analysis shows that rather than helping cut emissions, such a project would drive them up for at least 24 years.
New research reveals which sectors of the global economy fuelled the emissions decline during COVID-19. We have a narrow window of time to make the change permanent.
