Tonight we are launching our Net Zero Carbon Roadmap for Leeds, which shows a pathway for how Leeds can get to net-zero emissions by the city’s target date of 2030.

We're looking forward to hearing responses to the roadmap's presentation by members of the Leeds Citizens' Jury, Polly Cook of Leeds City Council, @SimonBowens of Friends of the Earth and Elizabeth Edgington of @BITC

Leeds’ carbon footprint has gone down: between 2000-2019 emissions fell by 40% (largely due to national decarbonisation of the grid).

Our share of the global carbon budget in 2020 is 31m tonnes; at ca. 4m tonnes a year, that’s used up by 2029

During lockdown #1, emissions were ca. 43% lower – overall, in 2020, they were ca 13% lower than normal. Sounds encouraging, but this only delays the point we eat up our carbon budget by 2 months!

Following science-based targets, Leeds needs to make 70% reductions by 2025 – which means another 25% reduction in emissions in the next 4-5 years.

We need to accelerate significantly!

Our report looks at Scope 1 & 2 emissions, but when you take in to account Scope 3 (net carbon from consumption and longer distance travel, inc aviation) the challenge is even greater: flights taken by Leeds residents add ca. 21% to the existing baseline.

How can we get to net-zero? The roadmap shows a range of cost-effective, cost-neutral and tech viable measures but this still leaves 40% gap…

Homes and transport dominate the top-ten list of cost-effective options.

Doing the cost-effective options would require £600m investment per year thru 2020s but would cut Leeds’ 2030 energy bill by ££651m a year and create getting for 15,000 years of extra employment.
This would close the gap by 41% …

Cost neutral and technically viable options get more expensive - from £900m a year up to £1.1m a year - but they would help to close the gap up to 60%.... That still leaves 40% gap to close....

To achieve Leeds' 2030 climate emergency target, we need to look at other innovative or 'stretch' measures.
That's ALOT of tree-planting, among other measures like hydrogen-based heating, electrification of domestic cooking, and more.

More from Tech

Recently, the @CNIL issued a decision regarding the GDPR compliance of an unknown French adtech company named "Vectaury". It may seem like small fry, but the decision has potential wide-ranging impacts for Google, the IAB framework, and today's adtech. It's thread time! 👇

It's all in French, but if you're up for it you can read:
• Their blog post (lacks the most interesting details):
https://t.co/PHkDcOT1hy
• Their high-level legal decision: https://t.co/hwpiEvjodt
• The full notification: https://t.co/QQB7rfynha

I've read it so you needn't!

Vectaury was collecting geolocation data in order to create profiles (eg. people who often go to this or that type of shop) so as to power ad targeting. They operate through embedded SDKs and ad bidding, making them invisible to users.

The @CNIL notes that profiling based off of geolocation presents particular risks since it reveals people's movements and habits. As risky, the processing requires consent — this will be the heart of their assessment.

Interesting point: they justify the decision in part because of how many people COULD be targeted in this way (rather than how many have — though they note that too). Because it's on a phone, and many have phones, it is considered large-scale processing no matter what.

MDZS is laden with buddhist references. As a South Asian person, and history buff, it is so interesting to see how Buddhism, which originated from India, migrated, flourished & changed in the context of China. Here's some research (🙏🏼 @starkjeon for CN insight + citations)

1. LWJ’s sword Bichen ‘is likely an abbreviation for the term 躲避红尘 (duǒ bì hóng chén), which can be translated as such: 躲避: shunning or hiding away from 红尘 (worldly affairs; which is a buddhist teaching.) (
https://t.co/zF65W3roJe) (abbrev. TWX)

2. Sandu (三 毒), Jiang Cheng’s sword, refers to the three poisons (triviṣa) in Buddhism; desire (kāma-taṇhā), delusion (bhava-taṇhā) and hatred (vibhava-taṇhā).

These 3 poisons represent the roots of craving (tanha) and are the cause of Dukkha (suffering, pain) and thus result in rebirth.

Interesting that MXTX used this name for one of the characters who suffers, arguably, the worst of these three emotions.

3. The Qian kun purse “乾坤袋 (qián kūn dài) – can be called “Heaven and Earth” Pouch. In Buddhism, Maitreya (मैत्रेय) owns this to store items. It was believed that there was a mythical space inside the bag that could absorb the world.” (TWX)
