China Briefing 15 May 2025: CO2 emissions fall; Drought affects food production; Climate diplomacy at CELAC  - Carbon Brief A new survey of Shanxi residents, exploring attitudes to climate change and “just transition”, offers a rare insight into the views of Chinese people on the frontline of the energy transition

This is some great news from China: emissions are falling dispite an increase in energy usage, let's hope that the emissions continue to fall!

⚡ Reviewing security of supply standards so that networks are designed for the future

👩‍🔧 Supply chains and workforce capacity managed to speed up project delivery

📅 Reforms to the planning system to speed up delivery

🗺️ Developing Regional Energy Strategic Plans for strategic planning to enable and de-risk proactive investment

💰 Simplify the price controls which control networks to deliver wider social and economic benefits, and efficient delivery

🧘 Going further and faster on digitalising the network and deploying flexibility

🔧 Proactive investment including accelerating ‘no regrets’ activities such as unlooping and off-gas grid reinforcement

🔌Improving the connections process through the introduction of minimum service standards

As heat, transport & industry electrify, demand for electricity will double by 2050, to meet this demand, networks will need to grow and be used in smarter ways.
This will be key for economic growth.

To do this, we have made recommendations around:

Electricity distribution networks: Creating capacity for the future - NIC

Today, at the #NIC we published the results of our study of electricity distribution networks.

Distribution networks deliver electricity to people's homes and most businesses.

It's LGBTQ+ history month. Myself, & other LGBTQ+ folk in STEM, work to improve inclusivity. But why is this needed?

The recent dismantling of inclusion initiatives, & the rise of anti-LGBTQ+ governments, it's important to reflect on why we do this 🏳️‍🌈👇🧵

The image shows a series of six line graphs depicting the trends in global emissions of different pollutants from 1750 to 2022. The title reads "The world has passed 'peak pollution'," indicating that emissions of several pollutants have declined since their peak levels, except for ammonia. The pollutants shown are: - Sulphur dioxide (SO₂) – peaked in the mid-20th century and has since declined. - Nitrogen oxide (NOx) – followed a similar pattern, peaking around the late 20th century and then dropping. - Carbon monoxide (CO) – peaked mid-20th century and declined. - Black carbon (BC) – shows a rise until recently, followed by a drop. - Organic carbon (OC) – has risen steadily with a recent plateau. - Ammonia (NH₃) – continues to rise without a recent decline.

The world has probably passed “peak air pollution”

Amazing, will give it a go, thank you!

I've not used twitter for ages now but does anyone have any advice on how to bulk delete my content on there?

This is what it looked like when we punched an asteroid back in 2018.

For science.

For the dinosaurs.

*NEW* heat pump installs reached a new record in October, under the Government's Boiler Upgrade Scheme

3,800 applications received in October ‼️

following a year of growth after the last Government upped the grant amount to £7,500

Want to ‘buy 🇬🇧 British’ energy for for heating?

By 2030, w/ renewable roll outs, heat pumps will use:

📍 55% LESS imported energy than today
📍 1/6 the imported energy of a gas boiler

Today, thanks to BUUK, I got to visit a wonderful zero carbon heat network in Suffolk. It will supply a new build suburban housing estate with heat and instant hot water from an air source heat pump.

It even had a thermal store to help reduce electricity demand during peak hours.

Stacked bar chart comparing the annual electricity and gas bills of a typical household (£1,717 total). Electricity costs £884, made up of £319 wholesale costs, £212 network costs, £141 policy costs, £122 operating costs, £48 other costs, and £42 VAT. Gas costs £833, made up of £416 wholesale costs, £158 network costs, £46 policy costs, £125 operating costs, £48 other costs, and £40 VAT.

Energy bills are going to rise again in January.
But what are we actually paying for in an energy bill? My colleague @martinakavan.bsky.social has written this lovely explainer, with some neat charts

Help to save households money and deliver cleaner heat to homes Up to 300,000 homes to benefit from upgrades next year, as government continues rollout of the Warm Homes Plan.

Great news! The government is going to remove the 1m planning application requirement for heat pumps.

This rule was putting people off getting a heat pump and makes it much easier for people in terraced houses to install one.

20 minutes to cover the energy infrastructure policy needed to meet net zero was a challenge but the questions show it was worth while!
