Carbon emission reduction: News and technology

[Brian Peacock]

You don't do irony do you!

In comparison to the proposed Electra, a 777 can carry c.46,000 lb of baggage/cargo and an A320 c.36,500 lb - so for a start we're going to need at least 15 times more of these than the number of 777s, and 12 times more than the number of A320s. I guesstimate around 146,000 Electra units are going to be needed to replace the 777 and A320 passenger units in operation - ignoring the sector's projected increases in capacity, production constraints on electrics, and the long haul shortfall of course.

You don't understand aircraft.
This aircraft does not fit in the niche of 777 et al.....the 777 does not fit in the niche of this aircraft.

A 777 cannot take off and land in a soccer field ...it's transcontinental.
The Hybrid is for short hops to places often with no airport. There is a reason for $8 billion in orders because there is strong demand for this category of aircraft.

WHERE did anyone indicate the aircraft is intended or designed to replace transcontinental aircraft.....beyond your rather flawed imagination. >?

You did, by posting it here in the carbon emission reduction thread rather than the aircraft thread.

What a specious jump of nonsense...it IS carbon reduction as well. Take off is the most energy intensive aspect of flying and using hybrid technology allows both the efficiency and extreme power of electric and the range of a steady state ICE engine.
You clearly have a mindset against things that fly....had to disabuse my partner about air freight vs sea freight as well yesterday.

Brian doesn't like it as it implies BAU in terms of shipping freight around the world. The only technology Brian likes is the kind that can be used to SMASH THE SYSTEM!

[Brian Peacock]

Brian smash!

What we need is teleportation technology. Quantum entanglement FTW!

Reading too much sci-fi ....I wish.

Meh. Once again you personalised the issues and avoided discussing the real problem - the elephant in the room if you will; the actual climate impacts of the aviation sector, its absolute fossil dependency, and the scale of the challenges it faces - both as an industrial sector of global reach and for those it employs and services. Is that really a good way to 'disabuse' people?

The back-of-an-envelope numbers I came up with speaks, in part, to the scale of those challenges. As you noted, the propsed Electras will only supplement a very specific niche within the sector overall, a sector that the industry itself expects to continue to grow past 2040. Thus the climate impact of small electric short hop cargo units is going to be negligible to nonexistent within the context of the sector as a whole - and they're still at the seeking R&D funding stage. In short, as welcome as the tech might be at some point it means very little without wholesale and concrete reform of the entire sector and its operating premises - even if electric flight eventually does actually get off the ground.

Bet you didn't click the link either.

We can't wait for future solutions to remedy the harms we're causing now, we need the solutions we have at hand implemented today. Relying on undeveloped future-tech to fix what we've already broken is prevarication, which is a stress response and effectively a form of denialism.

Climate crisis to blame for dozens of ‘impossible’ heatwaves, studies reveal.

Okay Brian what are YOUR "solutions we have at hand"??
••

you sound like the guy saying electric cars are not going to succeed a while back
....yet a decade later 93% of new registrations in Norway are electric.

Nah windmills, solar panels are no good ....yet renewables are over taking fossil fuels NOW for electric power for the planet.

Nuclear??/ more handwringing yet China use of fossil fuels is peaking now....why...renewables AND nuclear.

You conveniently ignore the $8 billion in orders - there are no technical breakthroughs needed for that plane....there are only certification to come which every new plane has to achieve.
Airbus understands it ...you don't...

5. CityAirbus
CityAirbus is gifted with various innovative design elements, such as fixed wings, a V-shaped tail and eight electric-powered propellers, as part of its distributed propulsion system. Designed for a quiet flight and use in urban environments, Airbus believes that urban and advanced mobility can ‘be moved into the sky to provide communities with additional ways to reach their destination’.

On the horizon, CityAirbus NextGen will use in-house and externally supplied components, ready for commercial use, as well as medical services and ecotourism.

Hardly a startup...

Your pouring scorn on every tech solution just gets tiresome especially when you don't introduce ANYTHING....just handwringing and specious complaints. Maybe you can score a hairshirt on Black Friday.

Why do you keep asking this question, and then ignoring my answers? It's as if you haven't actually read anything I've posted on the subject over the last decade or so.

Pff. You're not 'disabusing' me of anything here btw - more like just dissing and abusing if truth be told. You've run that 'hair-shirted, hand-wringing Luddite' skit enough already - and it's not like I haven't specifically addressed that charge a number of times as well. Could you perhaps represent my views in good faith rather than addressing your comments to a glib misrepresentation of my character and motivation next time please?

Saudi Arabia accused of modifying official Cop29 negotiating text

A Saudi Arabian delegate has been accused of directly making changes to an official Cop29 negotiating text, it can be revealed.

Cop presidencies usually circulate negotiating texts as non-editable PDF documents to all countries simultaneously, and they are then discussed. Giving one party editing access “risks placing this entire Cop in jeopardy”, one expert said.

Oil-rich Saudi Arabia is regarded by many as a persistent obstructor of action at UN climate summits to cut the burning of fossil fuels and has been described as a “wrecking ball” at Cop29.

Earlier on Saturday, a document was circulated by the Azerbaijani presidency with updates to the negotiating text on the just transition work program (JTWP). This aims to help countries move to a cleaner and more resilient future, while reducing inequalities.

The document was sent with “tracked changes” from the previously circulated version. In two cases, the document showed edits were made directly by Basel Alsubaity, who is from the Saudi ministry of energy and the lead on the JTWP. It was not sent to other countries to edit, the Guardian was told.

One of the changes deletes a section of text reading “encourages parties to consider just transition pathways in developing and implementing NDCs, NAPs and LT-LEDSs that are aligned with the outcome of the first global stock take and relevant provisions of the Paris agreement”...

NDCs are nationally determined contributions, NAPs are national adaptation plans and LT-LEDs are long-term low emission development strategies.

UK receives a top ranking in climate action...

Britain leads the world in cracking down on climate activism, study finds

British police arrest environmental protesters at nearly three times the global average rate, research has found, revealing the country as a world leader in the legal crackdown on climate activism.

Only Australia arrested climate and environmental protesters at a higher rate than UK police. One in five Australian eco-protests led to arrests, compared with about 17% in the UK. The global average rate is 6.7%.

The research comes amid an outcry over the targeting of climate and environmental protesters, with a rise in the suppression of dissent around the world as the climate, biodiversity and pollution crises take hold.

It found an increase in the number and proportion of protests linked to climate and environmental destruction over the past decade, but argued that rather than tackling the issues provoking them, states are focusing on punishing dissent.

Michel Forst, the UN special rapporteur for environmental defenders, said earlier this year: “In many countries, the state response to peaceful environmental protest is increasingly to repress rather than to enable and protect those seeking to speak up for the environment.”

The latest research paints a picture of extensive repression of climate and environmental protest in the global north and south, with distinct characteristics in each region contributing to the overall trend.

“There is an increasing criminalisation and repression of climate and environmental protest,” said Oscar Berglund, a political economist at the University of Bristol who led the study. “These kinds of protests have increased, climate protests quite sharply, and the response to this has been a crackdown that has to be seen in the wider political sense of a breakdown in climate action.”

Berglund and his colleagues looked at data collected by the Armed Conflict Location and Event Data database between 2012 and 2023, focusing specifically on the countries that had more than 1,000 protest events registered for that period. They then narrowed down their focus to 14 countries representing all six populated continents for a qualitative analysis.

Following academic convention, they drew a terminological distinction between environmental protest and climate protest. Environmental protests were defined as those that target destructive projects such as mining, dams or large scale construction, while climate protests are a generally newer phenomenon, mainly concentrated in the global north. They are geographically separate from the projects they oppose and have broader political demands.

The researchers found that both kinds of protest had increased, but the data showed a particularly sharp rise in the number of climate protests towards the end of the 2010s, coinciding with the growth of the youth-led Fridays for Future movement and groups such as Extinction Rebellion in the UK and the Sunrise Movement in the US...
