A Tufton St guide to "honest debate" on net-zero

(aka how Civitas got embarrassingly wrong numbers into Sun, Mail, Times & Express)

1⃣Send to lobby journos, not specialists
2⃣Get Tufton St chums to write supportive comment
3⃣Trust editors to take crazy numbers at face value

🧵 Image
A Tufton St guide to "honest debate" on net-zero (cont)

4⃣Pretend fossil-based tech is free
5⃣Ignore saving of buying less fossil fuel
6⃣Confuse MW & MWh so you can say wind costs £1,300,000/MWh (reality is £50-70/MWh)
7⃣Falsely assert gas power must close early & make up cost Image

8⃣Quote a report saying EVs cld lose 114k jobs but ignore bit where it says EVs cld support 246k jobs
9⃣Assume clean tech costs never change
🔟Make us pay for green energy & insulation twice Image

1⃣1⃣Make up a huge number for net-zero costs in farming, without evidence, because it's "not unreasonable to assume"
1⃣2⃣Make sure to ignore actual evidence of climate/gas costs driving food price inflation Image

1⃣3⃣Falsely imply the CCC cost estimates assumed a 0.1% cost of capital (not true)
1⃣4⃣Add a blanket 5.25% finance cost to figures that often already include financing Image
I'll share receipts for everything I said above in a moment, but first here are the outlets that credulously gave space to the Tufton St claims, without checking they weren't mad

Spectator gave space to Ross Clark to promote the claims, altho amusingly he clearly suspects Civitas numbers are bonkers as he gives himself this get-out

"There is no reason to suppose Civitas’ figures will turn out to be right…But they are an impt contribution to a debate" Image
The Times did not think the report worthy of news coverage, but gave a comment slot to another Tufton St groupie, Tim Knox, to promote Civitas' work (Knox fails to mention his association with the report, which says it "would not [have] be[en] possible" without him)
Image
Image
The Express gives space to another Tufton St outfit, the Taxpayers Alliance, for yet more uncritical supportive coverage of the bonkers Civitas numbers Image
The Mail did at least publish a response from govt saying “We simply do not accept these figures. The report fails to recognise the financial savings from lower fuel costs and technological advances – such as offshore wind costs falling by 70% more than we projected in 2016.” Image
Now onto the receipts:

Report does not include OPEX savings in lower fossil fuel bills and it ignores the capital cost of fossil-based alternative technologies (gas boilers, gas power plants, combustion engine cars), effectively assuming they are free and never need replacing

Image
Image
Image
Receipts

The report asserts that “147TWh of current capacity [sic]” will have to retire early, even though early retirement is explicitly ruled out in CCC pathways

The report then says, without citation or evidence, that this will cost £73bn, which appears to be based on 147/2
Image
Image
Receipts

The report asserts that heat pumps will cost £14k per house forever, even though some firms have already dramatically cut costs and are now offering to install the technology for as little as £5k, before grants

octopus.energy/press/octopus-…
Receipts

Paying twice:

The report includes an estimated cost to decarbonise the electricity system and then adds current subsidies for decarbonising the electricity system on top ("green levy"), assuming they continue at the same level forever (most are 15yr contracts) Image
Receipts

Paying twice:

The report includes a cost of £5k per household for insulation, for all 28m homes (5x28=140), then adds another cost to insulate social housing specifically, even though these are part of the 28m total Image
That's it from me, but before I go, please check out this amusing thread from Barney on how ludicrously badly excruciatingly wrong the Civitas report is

One more thing…

Of COURSE report author Ewen Stewart is a climate sceptic who wrote in 2021:

"Whether one believes in man-made climate change, or whether one believes that there has always been natural climatic variation, it remains a contested theory"

NEW: UK climate advisers now "more optimistic" net-zero goals can be met

🎯Net-zero "possible" + "good for economy"
📉CO2 halved vs 1990
📈More "credible" policies
🚘🏡EV/heat pumps soaring
But…
⚡"Critical" to cut power prices
✈️Flight CO2 "risk"

1/9 Image
For the first time I can remember, the CCC says its progress report is "optimistic" about UK climate goals being hit. Interim chair Prof Piers Forster says he is "more optimistic" than last yr due to last govt's policies starting to deliver + changes since Labour took office

2/9 Image
Another notable change is that the CCC seems to be getting less prescriptive…

CCC has faced (inaccurate) charges that it has, in effect, set govt policy. But it's now being clearer than ever that it only offers advice – and policy is up to govt.

IEA: Oil still on track to peak by 2030; oil for fuel to peak in 2027

"annual growth slows…to just a trickle over the next several years, with a small decline expected in 2030, based on today’s policy settings and market trends"

Here are some of the most striking charts 🧵
1/8 Image
In recent years, global oil demand has been almost entirely driven by growth in China…

…and that party is now over

Equally, US "dominance" of rising oil supply is also a thing of the past
2/8 Image
Since last year, the IEA has raised its oil demand outlook for the US, due to EV rollbacks etc, but it has simultaneously cut its outlook for China by the same amount

So global demand in 2030 is right where the IEA thought it would be last year

Could this be the biggest climate story of the year?

For the first time on record, China's emissions are falling due to clean energy growth, not slow power demand

Full analysis + outlook by Lauri Myllyvirta:


1/7 carbonbrief.org/analysis-clean…Image
In Q1 of 2025, the clean-energy driven drop in power sector CO2 outweighed small increases in other sectors of China's economy, driving a 1.6% fall year-on-year overall


2/7 carbonbrief.org/analysis-clean…Image
The fall in power sector emissions came despite surging electricity demand growth

This is the first time on record that clean energy growth has been sufficient to cut into coal power, without the help of weak power demand

FACTCHECK: Almost all the headlines on Tony Blair / net-zero are *wildly* inaccurate

REALITY:

1️⃣Net-zero is *only way* to stop warming
2️⃣Blair calls for tech to "turbocharge our path to net-zero"
3️⃣He categorically *does not* say "net-zero is doomed to fail"

🧵
1/6 Image
Blair says a "strategy based on either 'phasing out' fossil fuels in the short term or limiting consumption is a strategy doomed to fail"

This is logically & categorically not the same as saying "net-zero is doomed to fail"

(If you can't see why, I can't help you)
2/6 Image
Nor does Blair say "current net-zero policies are doomed"

Because literally no govt in the world has a current net-zero policy to "phase out fossil fuels in the short term or limit consumption"

Instead, world's govts agreed at COP28 to "transition away from fossil fuels"

NEW: Official advisers CCC say UK shld cut emissions 87% by 2040

⚖️Net cost of net-zero 73% less than thought
💷Total cost to 2050 = £108bn (~£4bn/yr, 0.2% GDP)
🏡🚗H’hold energy/fuel bills to fall £1,400
🔌Electrification is key

THREAD + charts



1/10 carbonbrief.org/ccc-reducing-e…Image
Just so we're clear, let's start with why bother

We're seeing record heat – 100% caused by our emissions – and extreme weather, from floods to droughts to heatwaves

IPCC says net-zero is only way to stop this getting worse



2/10 carbonbrief.org/state-of-the-c…Image
There’s also the global energy crisis, which hit UK particularly hard due to reliance on imported gas, crushing household (and govt) finances

UK has spent £140bn on gas since the crisis began (!)

Shift to net-zero would massively reduce exposure to intl fossil fuel prices

THREAD: New UK govt contract with Drax biomass power plant

* 4-yr contract 2027-2031
* £113/MWh (2012 prices – £155 in today's money)
* Output cap of 6TWh (<2% of UK supplies, cf recent yrs 12-15TWh)
* CfD cost ~£500m/yr
* 100% of fuel must be "sustainable", up from 70%
1/5 Image
UK govt says the contract helps security of electricity supplies, but gives Drax a "much more limited role than today" ie it's limited to run at roughly 25% of its max output

This means it's mainly going to be running when it isn't windy


2/5 questions-statements.parliament.uk/written-statem…Image
Drax has had issues with existing 70% sustainable sourcing rule, but as it'll need less than half the fuel it has been buying to date, the new 100% rule looks more achievable

Notably, new contract terms allow govt to reclaim subsidy if rule not met
