It's the second Conservative leadership #ITVdebate tonight & I'll be watching what they say about climate and energy like a hawk

On just before the debate  – news from @metoffice

90% chance of new UK heat record
60% chance of breaching 40C

Live THREAD + couple of previews

1/
Energy bills are almost certain to feature tonight, so let's start by setting the record straight: 94% of the coming rise to £3,300 in October is due to soaring gas prices

Green levies will fall from current 5% to ~3%

2/

We may also hear talk of gas as a "transition fuel", so it's worth remembering that gas is the single-largest source of greenhouse gases in the UK

Moreover, it's only a "transition" or "bridge" away from coal – except we've already crossed that bridge

3/
Q1 – cost of living crisis…

Truss mentions energy bills – "temporary relief on the energy levy" (which is worth max £150 on bills expected to reach £3,300)

Tugendhat wants to cut fuel duty – (fuel bills are high cos fossil fuels are expensive)

4/
Mordaunt to halve VAT on fuel at pump – worth max £10 on a £100 tank. (Driving an EV could save £60+)

5/

(Here's a chart showing why pump prices are REALLY going up – it's all about expensive oil – the red bit – tax take is **falling** as share of cost of filling a tank)

6/
(Oh look – another chart I prepared earlier – high pump prices in the UK are directly correlated with and actually caused by international oil prices)

7/
Thin pickings on climate & energy so far. What have I missed? Candidates have missed a lot – eg tackling demand, in homes, in cars etc

It's quickest & cheapest way to save ppl money!

eg driving 10mph slower on mway cuts journey cost by same amount as halving VAT on fuel

8/
To repeat, the UK's almost certain to see an all-time heat record over the next couple of days and quite likely to see first-ever temps above 40C…

…and yet, nearly 30mins into #itvdebate they've not been asked about climate change (nor have any candidates mentioned it)🤯

9/
Climate Q refs red warning on extreme heat. Would you back down on net-zero target?

Mordaunt: Yes, but mustn't "clobber ppl"
Tugendgat: (doesn't answer yes or no)
Badenoch: If there are things that will bankrupt country, I will change them…I do believe in climate

10/
Truss: I back the net-zero target. Moratorium on green levy and "take it out of general tax" (pay from, presumably?)
Sunak: Yes, but not "too hard and too fast"

11/
(oops, in those tweets "yes" was yes they support net-zero – in case that wasn't clear!)

12/
Quick thoughts – on Badenoch holding out prospect of net-zero bankrupting the country, that's…bold

Latest @theCCCuk report said, with current record-high fossil fuel prices, UK could actually **save 0.5% of GDP** by going to net-zero

13/

carbonbrief.org/ccc-costly-gas…
On Truss and green levies, I think she must have misspoken and actually meant she would temporarily pay for green levies out of general taxation

28m homes / £150 per home

= £4.2bn a year for the Treasury…

14/

The UK government's Net-Zero Strategy breached the Climate Change Act, the High Court has ruled

I've read the full 59-page judgement so you don't have to, as well as speaking with several lawyers

THREAD on the ruling & what it means

(TL;DR new strategy by Mar 2023)

1/ Image
The UK net-zero strategy was published in Oct 2021, setting out how govt planned to meet its legally-binding climate targets

Publishing the strategy was also a legal reqt under the Climate Change Act 2008

Our coverage at the time:

2/

carbonbrief.org/in-depth-qa-th…
As we wrote at the time, the strategy did not quantify the impact of the plans & policies it contained

That made it impossible for parliament – or wider public – to say if strategy was ambitious enough to reach the sixth carbon budget for 2033-2037

High gas prices are behind more than 90% of rising UK household energy bills

94% of the expected rise from £1,971 cap now to £3,285 in Oct is due to wholesale energy prices (& 91% since winter 2020)

Green levies will fall from 5% to 3% of bills

1/

carbonbrief.org/analysis-cutti…
The cost of buying wholesale gas & electricity will have increased from £359/yr last summer to current £1,069 & then to £2,245 in Oct

This is a giant 6-fold rise – thanks to pricey gas – from Summer 2021 to Winter 2022

(Bloomberg: "Gas soars 700%")

2/

bloomberg.com/news/articles/…
At the same time, "green levies" have actually been falling, because renewables are cheaper than gas

As wholesale costs soar, green levies will fall from current 5% of bills to <3% under the Winter 2022 cap

*All* govt taxes & levies, inc VAT, will make up <10%

Each coal power station requires 3,800,000 tonnes of coal per year & emits 7,500,000 tonnes of CO2.

If they last 25 years, they require 95,000,000 tonnes of coal & emit 186,000,000 tonnes of CO2.

They're not environmentally friendly.

(Unlike Sophie I'll give workings) Image
I've assumed a 1GW power plant, generating 7.5TWh at 85% load factor

EIA says avg US coal plant used 1.1lb coal per kWh in 2021 (0.51t/MWh) eia.gov/tools/faqs/faq…

EIA says avg US coal plant emitted 2.23lb CO2 per kWh in 2020 (1t/MWh)
eia.gov/tools/faqs/faq…
To generate as much electricity from onshore wind would require 2,100MW assuming 40% load factor (UK govt assumes 42% for new sites)

Arcelormittal says ~150t steel per MW so that's 320,000t steel

NEW ANALYSIS

UK CfD auction secures nearly 11GW of renewables that will generate electricity at prices 4x lower than current cost of gas

2.2GW solar £(2012)46/MWh
0.9GW onshore wind £42
7.0GW offshore wind £37 (!)
0.6GW island wind £56

CCC: Costly gas means reaching climate goals ‘could save UK 0.5% of GDP’

BUT progress report finds…

❌ UK govt strategy "won't deliver net-zero"
❌ Only 8 of 50 key indicators on track
❌ No “credible” plans for 61% of GHG cuts

THREAD

1/

carbonbrief.org/ccc-costly-gas…
Russia's invasion of Ukraine and sky-high fossil fuel prices "reinforce the case for a rapid transition away from fossil fuels", the CCC says, yet some are using it as an excuse to extract more or pause coal phaseouts

2/

carbonbrief.org/ccc-costly-gas…
High fossil fuel prices are also "shifting the economics of decarbonisation", the CCC says, improving cost advantages of renewables, EVs and efficiency

Result? If high gas prices continue, meeting UK climate goals would *save 0.5% of GDP*
