The Beginning of the End for Carbon Offsets? Parents Take Energy Giant to Court
Court case could upend Australia’s carbon offset industry and reshape corporate climate claims.

Hearings in the greenwashing case Parents for Climate v EnergyAustralia start today in the Federal Court.
As a backgrounder, this is my write-up of its significance, and its potential to deliver a reckoning for the carbon offset industry.

Wait, apologies, it sounds like nuclear is still on the table according to Dan Tehan.
So, it's no emissions reduction targets, and more coal and more gas without the pretense of trying to reach net zero with nuclear.
Probably the most honest policy position the Coalition has had since the Abbott government.

According to Sussan Ley, the Albanese government is simultaneously not cutting emissions fast enough and also cutting emissions too quickly.

Summary of Sussan Ley:

- Liberals will repeal the net zero target in legislation
- Liberals will also repeal the 43% by 2030 target

Global emissions from fossil fuels will grow 1.1 per cent in 2025.
"For a 50 per cent likelihood to limit warming below 1.5°C, the remaining budget is 170 billion tonnes of CO₂, equivalent to four years at the 2025 emissions levels."

The Coalition really read the National Climate Risk Assessment, and its warnings of increased heat deaths, bushfires, drought and sea-level inundation and were like 'sounds good to us'.

Badly worded poll published by the SMH, which implies that it’s more costly overall/less affordable to reach net zero. Verging on a push poll.
Despite this, a majority of Australians still support net zero.

Homo Sapiens emerged about 300,000 years ago.
Imagine you gave an early Sapiens $9,000. And they looked at you and said “the fuck is this?”
But anyway, you piled up $9,000 Every Single Day since the first Sapiens walked the Earth.
You still wouldn’t have a trillion dollars.
Capitalism is fucked

A new edition of the UNEP's Emissions Gap Report is out. It shows countries making little progress in ramping up ambition, and the very low likelihood of current commitments limiting warming to 1.5 degrees.
We're probably avoiding 3 degrees, but there's much more to do. www.unep.org/resources/em...

This 'free solar hours' announcement is smart politics, associating free electricity with renewables.
It's also reflects the real market, with wholesale electricity prices dropping below zero every day this week in NSW and QLD during the solar peak.

A member of the Senior Executive Services (SES, i.e. a senior public servant) within the climate and environment department accepted a gift ticket from Woodside to attend an industry conference.
Question is why even accept this when tickets were just $150.
Conflicts of interest come pretty cheap.

Can you help raise funds for the RSPCA NSW?
I'm hoping to raise $3,500 as part of my plan to take on the Sydney Marathon next year - using it as a good excuse to support good causes. I'd love any support you might be able to give!
