Increased taxation of the gas industry, whether through a reformed resource rent regime or otherwise, would improve national capacity to enable and fund that transition.

Bill Hare @billhare.bsky.social · 05/05/2026
Government policies should tax gas exports to maximise public returns within a closing window for a profitable exploitation of Australia’s fossil fuel resources, including for the purpose of more quickly scaling up zero emission solutions.

Bill Hare @billhare.bsky.social · 05/05/2026
Some of the Committee's questions reflected the gas industry's arguments that taxing it might deter long term investment. Our response: the fossil gas role in global energy systems will need to rapidly decline - that's if the world is to meet the agreed Paris Agreement goals.

Bill Hare @billhare.bsky.social · 05/05/2026
The growing ability of battery storage, grid transmission, and demand management technologies to affordably firm renewables further undercuts arguments in favour of fossil gas being critical to the energy transition.

Bill Hare @billhare.bsky.social · 05/05/2026
Fossil gas is increasingly substitutable in all sectors where it's used, and often more cost-competitive. In the power sector renewables are the cheapest form of new electricity generation in Australia and a growing cohort of other countries, even including system integration costs.

Bill Hare @billhare.bsky.social · 05/05/2026
Our own modelling shows the volume of natural gas “needed”, rapidly declines with time, despite the claims of fossil gas industry members and supporters, who are promoting a sustained role for their product.

Bill Hare @billhare.bsky.social · 05/05/2026
The IEA’s scenarios are widely regarded as credible, and its Net Zero Emissions scenario, cited in the Future Gas Strategy's Analytical Report, shows global gas demand falling by 78% between 2023 and 2050, alongside a projected halving of Australia's market share.

If the EU wants a chance of reaching net zero emissions by 2050 and staying on track with the 1.5°C limit, it needs to ramp up ambition: it needs to at least ensure its 2040 target of 90% net reductions is reached domestically and ideally increase it to 95% 🔗 climateactiontracker.org/press/respon...

China released its 15th Five-Year Plan (FYP). The plan reinforces the rapid expansion of clean energy, but it does not translate this momentum into stronger binding emissions targets. Read our full reaction here 🔗 climateactiontracker.org/press/reacti...
White text on blue background with CAT logo. Text is a quote saying "China's 15th five year plan is a missed opportunity. 

While it continues to strongly  emphasise clean energy development, it could have gone further. 
 
A 17% reduction in carbon-intensity target would actually allow China's emission to increase by 3% under a conservative GDP growth.”

Bottom line: Don’t confuse “hard” with “obsolete.” The world doesn’t need permission to lower ambition. It needs governments to implement what they already agreed—at the speed and scale that 1.5°C demands.

The pursuit of 1.5°C endures as a legal and ethical imperative in a changing world

Bill Hare @billhare.bsky.social · 30/01/2026
And let us not forget that the Paris Agreement’s 1.5°C warming limit remains the world’s enduring legal, political, and moral anchor for climate action – abandoning it would only deepen injustice for vulnerable communities already bearing the brunt of climate change.
110
Bill Hare @billhare.bsky.social · 30/01/2026
In all this that should not be forgotten that since 2015, the Paris Agreement has provided quantified targets at national and global levels consistent with limiting warming as close as possible to 1.5°C.
110
Bill Hare @billhare.bsky.social · 30/01/2026
Whilst “Clean-energy shift” can be a useful slogan it can’t replace the temperature limit and by itself generate the time bound actionable targets needed to protect us from dangerous climate change.
110
Bill Hare @billhare.bsky.social · 30/01/2026
The Paris Agreement provides the basis to design critical clean energy benchmarks to limit overshoot as low as possible and get warming back below 1.5° by 2100. Without the 1.5C limit it is unlikely that the right benchmarks would be calculated or chosen.
110
Bill Hare @billhare.bsky.social · 30/01/2026
On geoengineering: the push for risky interventions grows because of delayed action not because of the 1.5oC limit. The answer is not to abandon 1.5°C—it’s to act fast enough so we don’t drift into an “anything goes” approach unguided by what we need to protect ourselves from and call it pragmatism.
110
Bill Hare @billhare.bsky.social · 30/01/2026
This scenario shows the time bound actionable targets needed globally to strictly limit overshoot and reduce warming below 1.5° by 2100. For example, renewables capacity needs to grow significantly, with a 3.5-fold increase by 2030 – ahead of the global tripling goal agreed at COP28.
110
Bill Hare @billhare.bsky.social · 30/01/2026
In terms of a clean energy shift this highest possible ambition scenario shows that global electricity generation needs to quadruple by 2050, with wind and solar supplying over 90% of electricity demand by then. Fossil fuels would be effectively phased out shortly afterwards.

Bill Hare @billhare.bsky.social · 30/01/2026
This work shows how to minimize overshoot and return to well below 1.5°C by 2100 with renewables, electrification, efficiency, methane cuts, deforestation reduction—reaching net zero around ~2060 if governments deliver.

We all agree we need actionable targets to guide policy. But here is the big thing: The Paris Agreement’s climate goals - the1.5oC limit and net zero in 2nd half of the century - provide the essential and critical legal and scientific basis for what clean energy targets are needed and by when.
