Heavy-industry sectors like cement have long struggled to decarbonise because their processes require very high temperatures.
That’s why the new Rondo Energy heat-battery project in Thailand is such a big deal - powering a cement plant with low-carbon steam.

Clinker production, the main ingredient in cement, is the primary source of CO2 in cement manufacturing.
By replacing clinker with other materials like fly ash, slag, or other industrial byproducts, the need for this energy-intensive and carbon-releasing process is significantly decreased.

Now that we are likely to cross 1.5°C, there is increasing discussion on "overshoot".
There is a lot of uncertainties on overshoot, but there is one thing that we are 100% sure about:
GHG emissions need to go down >90% in decades for overshoot to be a reality.

European Commission President Ursula von der Leyen said today that the fight against climate change was not against the fuels that cause it — only the pollution they emit.

China's electricity consumption grew a whopping 10.4% year-on-year in October. Partially explained by big jumps in residential and service sector demand, up by 24% and 17%, but industrial demand also up 6.2% - looks like an end of five-year plan push to meet economic targets.
China's power generation from coal and gas saw a big jump in October, rising 7% on year. Generation is still down marginally, 0.4% in the year to October. Likely reasons: weather variation affecting residential&commercial power demand, and solar&wind curtailment.

This trend continued in the third quarter of 2025, when emissions were unchanged year-on-year.
If this trend starts to move into sustained carbon emissions reduction it would be hugely significant.

This a big deal: "China’s carbon dioxide emissions have been flat or falling for 18 months"
China's economy has grown by ~5% in the last year, so this comprehensively debunks the idea (again) that emissions are tied to growth. So yes, faster progress needed, but this is how you turn the corner.
