Quick Summary

The High Court of Australia ruled that the approval for MACH Energy's Mount Pleasant coalmine expansion in New South Wales was invalid because it failed to consider minimizing greenhouse gas emissions generated when the mined coal is sold and burned overseas. This decision, which received support from environmental advocates like NSW Greens MP Sue Higginson, establishes a precedent requiring consent authorities to account for these "scope 3" emissions. Higginson urged legal action against other coalmine approvals based on this ruling, indicating potential challenges for projects like the Hunter Valley Operations extension.

Story summary

The High Court in Australia ruled that planning authorities must consider local climate change impacts from global greenhouse gas emissions when approving fossil fuel projects. In a 3-2 split decision, the court dismissed MACH Energy's appeal against a New South Wales Court of Appeal ruling that halted the expansion of its Mount Pleasant coal mine near Muswellbrook. The case was brought by environmental advocates who argued that planning authorities failed to account for "scope 3" emissions — those caused when exported coal is burned overseas. The court found that such emissions must be minimized as much as possible under New South Wales planning law, setting a precedent expected to influence future fossil fuel project approvals across the country.

“While both articles discuss a High Court ruling affecting fossil fuel projects and climate change considerations, Article A focuses on the specific ruling against MACH Energy’s Mount Pleasant coalmine expansion in NSW, whereas Article B discusses broader implications for Western Australia's oil and gas industry.”

🔮 These mysterious pulses were first discovered in 2007 and have puzzled scientists ever since, with speculation from some that they could have an alien origin.
🔮 In a 3-2 split ruling, the high court found the state’s Independent Planning Commission (IPC) failed to consider imposing conditions to minimise greenhouse gas emissions that would be generated by the mine when the coal is sold and burnt overseas.

Narrative

In a joint statement, Liberal leader Angus Taylor and Nationals leader Matt Canavan described the decision as a threat to “Australia’s standing as a reliable energy exporter”, and said the federal and NSW governments “must act immediately to fix the law”. “A project extension the Independent Planning Commission approved in 2022, after years of assessment, has been sent back to square one,” they said, arguing that the Minns government should amend NSW’s environmental planning and assessment act, to “make clear that overseas emissions from Australia’s exported resources are not a consideration in project approvals”.

A landmark decision in Australia’s first climate change high court case has been described as a clear message to governments and fossil fuel companies that exported greenhouse gas emissions “cannot simply be ignored”. asserted
decision → describe → governments
On Wednesday morning, the nation’s highest court ruled that the approval of MACH Energy’s Mount Pleasant coalmine expansion in NSW’s Hunter Valley was invalid, in a judgment that sets a precedent for fossil fuel projects in the state. asserted
that → rule → state
The coal company brought the high court case after a local community group, the Denman Aberdeen Muswellbrook Scone Healthy Environment Group (Dams Heg), halted the coalmine expansion on climate grounds in the NSW court of appeal. asserted
group → bring → appeal
In a 3-2 split ruling, the high court found the state’s Independent Planning Commission (IPC) failed to consider imposing conditions to minimise greenhouse gas emissions that would be generated by the mine when the coal is sold and burnt overseas. asserted
coal → find → mine
Known as scope 3 emissions, these are not counted in Australia’s domestic tally. asserted
these → know → tally
Commenting on the judgment, deputy Greens leader Steph Hodgins-May said: “For too long, big coal and gas companies have tried to pretend that the emissions from their products are someone else’s problem once they leave Australian shores. uncertain
they → comment → shores
They’re not. asserted

“When Australian coal is burned overseas, the climate damage doesn’t magically disappear at the port. asserted

NSW Greens MP Sue Higginson, formerly a public interest environmental lawyer, also said the high court judgment could lead to “significant legal difficulty” for the Hunter Valley Operations (HVO) coalmine extension, which was approved by the IPC a week ago. uncertain
which → say → IPC
In greenlighting the HVO extension – the biggest in the state’s history – the IPC ruled that emissions from the mine would “contribute to climate change impacts on the people, economy and environment of the Hunter region, NSW and globally”, but that their impacts had been outweighed by economic benefits to the region. asserted
impacts → greenlighte → region
For both the HVO and Mount Pleasant coal developments, 98% of the emissions were scope 3 emissions, Higginson said. asserted
Higginson → say → emissions
“HVO’s environmental impact statement didn’t even account for scope 3 emissions at all, and the high court has been crystal clear that consent authorities must ensure emissions are minimised to the greatest extent practicable. asserted
emissions → account → extent
It seems clear that the approval of HVO fails this test. asserted
approval → seem → test
“Lawyers should be running to the courts right now with this judgment in hand, ready to stop coal approvals in their tracks,” she said. asserted
she → run → tracks

we → chair → that
If others don’t, if others are so biased in their approach that they don’t respect the law of the land, that’s a matter for them. asserted
that → do → them
It says a bit about their approach, but that’s about as all I’m going to say because it’s a court case and I’m not in Australia at the moment.” asserted
it → say → moment
Murray Watt, the federal environment minister, said on Wednesday afternoon that while he had not had an opportunity to review the judgment in full, “the decision from the high court is in relation to a New South Wales government decision based on New South Wales legislation”. asserted
