China Briefing 15 May 2025: CO2 emissions fall; Drought affects food production; Climate diplomacy at CELACΒ  - Carbon Brief A new survey of Shanxi residents, exploring attitudes to climate change and β€œjust 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!

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:

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 πŸ³οΈβ€πŸŒˆπŸ‘‡πŸ§΅

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 (SOβ‚‚) – 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.

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

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.

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.
