In its decision, the Supreme Court of Canada recognized the gravity of climate change and upheld the idea that Parliament has the authority to act on matters of "peace, order and good government."
Both sides can make a case, but they might not get the chance.
It's said the best predictor of future behaviour is past behaviour. Let's hope that's not the case with Mathias Cormann's climate stance when he joins the OECD.
For an orderly transition from fossil fuels, Australia needs a carbon price to replace its hodgepodge of clumsy government interventions.
None of Canada's past climate targets or plans has been credible. But the math on the latest plan, which relies on a steadily increasing carbon price, could have Canada meet its 2030 goal.
If Canada began to reduce its greenhouse gas emissions by about four per cent per year, we could still meet our 2030 climate targets.
Australia faces a carbon tax being imposed on it by its trading partners. It's time to get ahead of the curve.
While much of the world moves towards zero-carbon economies, a NSW mega-plan for new renewables may set up the state as an energy superpower.
A diverse group of experts including representatives of oil companies and banks unanimously agreed that climate change poses an existential threat to the financial system.
COVID-19 pandemic has seen the Morrison government abandon long-held dogma on debt and deficits. But on climate and energy, it's singing from the same old songbook.
It's encouraging that the federal government recognises its role in industry policy. But its choice to support some technologies is disappointing.
The Paris climate change agreement aims to limit global warming to 1.5C above pre-industrial temperatures — and the federal carbon pricing plan was meant to help Canada meet its commitments.
We cannot rely on technology development alone to deeply cut Australia's emissions. Other policies and more money will be needed.
Having a carbon price is linked to lower emissions growth. A larger price cuts emissions by more.
Making the solutions cheaper – rather than the problems more expensive – could reduce emissions more fairly.
The climate action plans of three companies in different industries – Delta Air Lines, Amazon and Microsoft – illuminate the three key strategies needed to cut carbon emissions.
In all the strategies and tactics of the climate wars, the most disturbing development is that the carbon pricing became roadkill.
The case for carbon pricing is not as ironclad as the case for climate action.
We analysed what the world's top 58 airlines – such as American Airlines, British Airways and Qantas – are doing about climate change. Even the best airlines are not doing anywhere near enough.
There's been one notable exception to Doug Ford's supposed willingness to change direction: the environment.
