The German environment minister earlier this year confidently claimed Germans would buy German and European cars anyway. Almost 50% of plug-in hybrid sales in Europe are now Chinese. Turns out growing Chinese car quality meeting a 20-30% undervalued exchange rate matters! Who could've known? 7/

10 Years Post-Paris: How emissions decoupling has progressed
Global CO2 emissions are still rising, but this masks a striking shift beneath the surface: a growing share of the world economy is now managing to grow while cutting CO2.

Alejandro Nuñez-Jimenez @anunezjimenez.com · 13/12/2025
China, the world’s biggest emitter, "is reducing its dependence on fossil fuels. Between 2015-2023, China’s consumption-based emissions rose 24%, less than half the growth of its economy (over 50%). For the past 18 months, its emissions have plateaued and many analysts believe they may have peaked."

I agree. How "visible" these trends are in terms of easily accessible data may play a role. I imagine that new car registrations are easier to find as data and compare across countries than, say, sales of bikes and electric bikes.

Totally agree, I just don't have the data at hand to say much about how modality changes may be affecting the oil demand for transport in China. Based on the report, it does not sound like they're having the most important factor, but that doesn't mean they are necessarily unimportant.

Alejandro Nuñez-Jimenez @anunezjimenez.com · 06/12/2025
Based on the report, passenger cars seem the major driver. "Railway passenger reached a record high of 3.5 billion in Q1-Q3 of 2025, a 6% year-on-year increase. Air travel passengers grew slightly slower, by 5.2% compared to 2024, to 581 million passengers." But probably many factors are involved!

Alejandro Nuñez-Jimenez @anunezjimenez.com · 06/12/2025
The driver of lower oil demand for transport seems clear. One in ten buses and passenger cars rolling on the streets in China in 2025 were new energy vehicles (BEV, PHEV, FCEV). Average sales of new passenger cars for the past 12 months are now over 50% new energy vehicles.
New energy vehicles' share of sales and vehicles on the road in China by category is going up.

China's oil consumption for transport may fall in 2025 almost as much as it did in 2020, during the pandemic. "China’s oil consumption [for transport] is projected to fall for the 2nd consecutive year in 2025, declining by 4.6% year-on-year and by 7.2% compared to 2023."
Annual change in China’s oil consumption in transport compared to energy transition pathways. Oil consumption has fallen in 2025 nearly as much as in 2020.

Emily Grubert @gruberte.bsky.social · 21/11/2025
🚨job alert🚨 I'm looking to hire at least one PhD student for next year, looking at decarbonization-oriented technology deployment within an ethical frame of resource allocation and justice outcomes. Full ad attached! Pref for CEEES admissions; deadline is 1 January.
Screenshot, job description: The “Ethical Technology Transitions to Mitigate Climate Change” program seeks one PhD student to be advised by Dr. Emily Grubert either in Notre Dame’s Civil and Environmental Engineering and Earth Sciences (CEEES) program (School of Engineering) or the Sustainable Development (SD) program (Keough School of Global Affairs). This position is fully funded for four years (anticipated stipend: $36,000/year) and will be supported by the resources associated with the Ethics and the Common Good program chair for three years, with remaining funding to come from other sources that might carry additional deliverable requirements (e.g., a secondary project) that will be clearly communicated to the candidate. The primary research area for this position will focus on ethical considerations related to technology deployment for reducing and removing greenhouse gas emissions from the atmosphere, with a particular focus either on modeling distributional effects of particular deployment patterns associated with net-zero greenhouse gas emissions pathways (CEEES PhD) or on designing governance systems for emerging technology systems, including Carbon Dioxide Removal (CDR); hydrogen; renewable electricity; or end use electrification technologies (SD PhD). Teaching requirements are aligned with the requirements of the specific degree program. Funding is available for conference attendance, and students will have the opportunity to work with and/or mentor undergraduate research assistants.
