Australian power sector must exit coal by 2030 to play its part in climate fight: study
Using the latest science from the Intergovernmental Panel on Climate Change (IPCC), the report – For Climate’s Sake: Coal-free by 2030 – found that in order for governments to fulfill their obligations under the Paris Agreement, OECD countries, including Australia, need to phase out coal in their electricity sector by 2030, (globally by 2040).
Coal, the most climate-damaging fossil fuel, still supplies about 60 per cent of Australia’s electricity, making its grid one of the most polluting in the world and among developed economies, the report shows.
“Australia would be well advised to fully decarbonise its electricity generation quickly, as it is a fundamental step in cutting emissions in all other sectors, where electrification plays an important role. Delaying coal phase-out will mean that the necessary emission reductions to meet climate targets is going to be even harder and very expensive,” said report author Paola Yanguas Parra, who leads the work on decarbonisation strategies at Climate Analytics.
Australia’s coal power stations are already technically obsolete and increasingly unreliable: they fail during extreme heat waves, on occasion leading to blackouts. They also have extremely weak air pollution controls and cause substantial adverse health effects.
If Australia’s power plants continue to operate to the end of their technical lifetimes, as current policies foresee, they would emit twice more (194%) than the remaining power sector carbon budget for coal in line with the Paris Agreement.
“Australia has a massive potential for renewable energy and replacing coal with renewables will have large economic and environmental benefits in terms of jobs, lower power costs, and reduced air pollution. Yet international investors are increasingly wary of us as a country, because of our continued reliance on coal – and we stand to lose out, economically,” said Bill Hare, CEO of Climate Analytics.
So far, global warming has already caused events such as major damage to the Great Barrier Reef, and climate projections show that Australia is extremely vulnerable to the effects of global warming.
As temperatures rise, Australia can expect even less winter rainfall, with more drought, more frequent periods with a high wildfire risk, a longer fire season, and people will be more exposed to dangerous heat extremes. And if warming is not limited to 1.5oC we risk the complete loss of the Great Barrier Reef.
“The realisation that climate change poses an existential threat to Australia is certainly hitting home right now, as as communities across New South Wales and Queensland are reeling from the devastation of the recent unprecedented bushfires. Clearly the world needs rapid emissions cuts and Australia must play its part in fighting climate change, and it could start by switching from coal to renewables in its own electricity system,” said Hare.
Carbon capture and storage could unleash 86 billion tonne carbon bomb
A new analysis finds reliance on carbon capture and storage could release an extra 86 billion tonnes of greenhouse gases into the atmosphere between 2020 and 2050.
Projected warming almost unchanged for two years as governments push false solutions over climate action
Despite their promises, governments have not taken enough action to drive down warming projections, with some instead turning to false solutions such as carbon capture and storage to continue the world's reliance on fossil fuels, according to the Climate Action Tracker's annual warming update.
Oil and gas majors could have paid for their share of climate loss and damage and still earned 10 trillion USD: new report
Global climate damages from emissions associated with the top 25 oil and gas ‘carbon majors’ between 1985 and 2018 are estimated at 20 trillion USD compared to the 30 trillion USD they earned over the same period, according to a new report released today by international think tank Climate Analytics.
A 1.5˚C pathway for the Philippines power sector entirely feasible: analysis
With the right international funding and policies in place, the Philippines could transition its’ power sector to near-100% renewable energy without compromising on the costs of electricity, reducing its reliance on expensive imports of both coal and gas, and creating up to a million jobs by 2050.
State of Climate Action report finds progress lags on every measure except EV sales
Global efforts to limit warming to 1.5°C are failing across the board, with recent progress made on every indicator — except electric passenger car sales — lagging significantly behind the pace and scale that is necessary to address the climate crisis.
Governments plan to produce double the fossil fuels in 2030 than the 1.5°C warming limit allows
The Production Gap Report finds governments plan to produce around 110% more fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C, and 69% more than would be consistent with 2°C.
Beetaloo fracking and Middle Arm emissions wildly underestimated: analysis
An independent analysis of the projected emissions from the Northern Territory's proposed Beetaloo Basin gas fracking project — and the associated Middle Arm LNG precinct in Darwin Harbour — has found they've been gravely underestimated, as have the availability of offsets to deal with them.

Three leading comic creators have collaborated with the Horizon Europe project, CONSTRAIN, to develop comics exploring the climate change challenge.

Changes to the jet stream could trigger simultaneous crop failures impacting global food security
This new study finds that the jet stream – air currents in the upper atmosphere – can synchronise extreme weather caused by climate change, resulting in crop failures in multiple countries at the same time.
