A price on carbon introduced by the Labor government, dubbed the “carbon tax”, was more effective at motivating big emitters to act, compared to the current Direct Action plan.
New research has found that carbon intensive companies have lost focus on reducing emissions under Direct Action, when compared with the carbon tax.
Nne-star-rated ‘Catalyst’ houses built to maximise passive solar principles were evaluated against seven control houses built to DHHS standards.
Emerging research challenges the idea that sustainable housing is unaffordable. It shows sustainability and good design can be affordable when analyses include social, health and wellbeing benefits.
Half a degree could make all the difference for the Great Barrier Reef.
A new report published by the Climate Institute says Australia could avoid lengthy heatwaves and help save the Great Barrier Reef by meeting the Paris Agreement's 1.5C global warming goal.
Australia will likely have to close more coal power stations to meet climate targets.

Australia's energy watchdog has warned that closing coal power stations could leave us vulnerable to supply problems. But not if we help take the pressure off the grid.
Victoria has joined three other states and territories in setting a renewable energy target.

Victoria has announced a renewable energy target of 40% by 2025.
Wasting food, wasting the earth.
Feeding Melbourne generates over 900,000 tonnes of edible food waste every year, enough to feed more than 2 million people.
Airlines have saved energy by changing flight routes and modifying wings for better fuel use.

Companies could improve their profits 2-10% each year by saving energy, according to a world-first attempt to assess energy performance.
Labor has promised 50% of electricity will come from renewable sources by 2050, but has left the detail for after the election.

Labor's detailed climate policy is ambitious, but it remains to be seen if it will capture the voters.
Green planet: tropical rainforests have produced more growth in response to rising carbon dioxide.

Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
An LNG tanker leaves Gladstone, Queensland. Gas development is one of the drivers behind Australia’s increasing emissions and electricity demand.
Over the past year Australia's greenhouse gas emissions from electricity rose 2.7%.
Electricity emissions have risen by 5.5% in the past two years due to increasing demand and the scrapping of Labor’s carbon price.
Modelling done for the Climate Institute indicates that without big policy changes Australia's path to zero emissions from the electricity sector by 2050 would mean huge disruption after 2030.
Self-driving cars are way more energy efficient than your average vehicle – but that doesn't necessarily mean they'll reduce carbon emissions.
Is the sun setting on coal investments?
Energy companies are realising that, in light of the Paris climate deal, the economics are starting to line up in favour of climate action, not against it.
The Great Barrier Reef is made up of thousands of individual reefs.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
The mussel hustle.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
Renewable energy is at the more expensive end of the emissions cost curve, but is a vital piece of the bigger picture.

Australia's greenhouse emissions are once again rising, after a decade of consistent declines. But the right policies are already in place to turn things around - they just need to be ramped up.

The IMF wants a levy on ship and plane fuel, but that won't magically create low-carbon alternatives.

National Archives of Australia
The National Archives of Australia today released selected federal cabinet records for 1990 and 1991. They reveal intense battles over Australia's domestic climate targets and, above all, a palpable determination that Australia not damage its coal revenue.
If shipping and aviation don't rein in their emissions it could seriously jeopardise our goal of preventing more than 2℃ of warming.
While low emissions technology might help coal, there are plenty of other energy sources competing in the post-Paris climate race.

Despite its vital role in the development of Australia's economy, the future of coal looks grim in a world aiming to limit warming to below 2℃.
