Some of Australia's biggest property companies are making ambitious emissions-reduction pledges – but how well are they really doing?

The IPCC report says extreme sea level events that used to hit once a century will occur once a year in many places by 2050. This situation is inevitable, even if emissions are dramatically curbed.
Using blockchain to power Australia’s carbon market could deliver tangible results.
Under the current rules, the federal government takes the most responsibility for buying carbon credits. A blockchain-driven market would be faster, smarter, and much more open.

Ahead of the UN climate summit, we take stock of the world's best and worst performers on climate action - including some surprise success stories.
The Port Kembla industrial area in NSW. Industry emissions can be cut by improving efficiency, shifting to electricity and closing old plants.
The UN has asked world leaders to bring concrete climate action plans to this week's summit - and Australia is likely to cop heavy criticism.
The Opal nuclear research reactor at Lucas Heights in Sydney. It does not produce nuclear energy but is used to produce medical radioisotopes and for other purposes.
The state of Australia's energy and climate change policy is reason to despair. But there may be a nuclear solution that keeps both sides happy.
Energy minister Angus Taylor has a range of options when discussing complex emissions data.

Australia's new emissions data for the December 2018 quarter show a rise on the previous quarter, although the raw figures actually dropped. Here's what that all means.
It’s not cows’ fault they fart, but the methane they produce is warming the planet.
Removing human-related methane from the atmosphere could reduce global warming by 15%.
Bill Shorten and his colleagues are offering a broad suite of policies, but little explicit mention of cutting out fossil fuels.

Labor has ditched its reliance on a single economy-wide climate policy, in favour of a range of different measures that will all help drive down emissions. But some crucial issues remain unaddressed.
Unconventional gas wells are being approved in their thousands across Australia.

Gas mining is expanding across Australia, and has been touted as part of the answer to cutting emissions. But there is evidence that this rollout will pose significant health and environmental risks.
Steel mills, like this one in Hamilton, Ont. emit greenhouse gases. Ontario must reduce its emissions from 161 megatonnes to 143 megatonnes by 2030.
Ontario's new environment plan scores poorly on conservative ethos.
Many of Australia’s biggest emitters have not yet engaged with the Emissions Reduction Fund.

The federal government has signalled its intent to prolong the Emissions Reduction Fund. But surveys of business leaders reveal widespread cynicism about a scheme perceived as politicised and bureaucratic.
The closure of the Hazelwood mine has lessons for the future of coal in Australia.

An international report has found there's no future for Australia's coal exports.
Australia’s energy emissions fell slightly due to renewable energy, but it’s not enough.
Australia is falling behind on its Paris targets, but we have many options for improvement.
Sens. Joseph Lieberman, left, and John McCain, right, at a legislators’ forum on climate change in Washington in 2007.
The late Sen. John McCain was an early – and lonely – Republican supporter of action to fight climate change. His challenge was to regulate sources of energy that underlie much of our economy.
A real fire in southern New South Wales - not to be confused with the metaphorical one in the halls of Canberra.

With New South Wales suffering winter bushfires and temperature records tumbling around the globe, our leaders in Canberra have picked a bad time to jettison climate policy in favour of political bickering.
President Trump is challenging the US states’ right to set their own emissions targets.

It's time Australian states took a lesson from US states when it comes to working around obstructive federal climate change policies.
Modelling should be a chance to test your assumptions, not just confirm them.
We need to move past biased, opaque models for energy policies.
Prime Minister Malcolm Turnbull and federal energy minister Josh Frydenberg have been forced to back down on plans to legislate emissions reductions for the electricity sector.

Prime Minister Malcolm Turnbull has abandoned the emissions-reduction component of his signature energy policy, in the latest chapter of a brutal decade-long saga for Australian climate policy.
Taking the long view is difficult when it comes to something as complex as energy policy.

A policy that aims to reshape the electricity sector needs to be judged on its numbers. But the lack of public modelling from the Energy Security Board makes it impossible for analysts to do this.
