He gets 350 km of range which lasts him a full day driving in Sao Paulo, not least thanks to recuperation going down its many hills. So far he charges for 2 hours during his lunch break but still loves it. Many nice features for the passengers: USB charging, cup holder, sliding door, coat hanger. /2

Thanks, Robert. Do you have any idea on when? Is that something that the UNFCCC does, or is that up to the party?
It seems that at least the NDCs in Spanish don't get an English translation (e.g. Chile submitted in September 2025, or Uruguay submitted in December 2024 are without translation)...

The report is based on detailed sector policy modeling with the global GCAM model, and also explicitly addresses the role of Canada as a fossil fuel exporter, showing that the country is at a crossroads of either locking-in further dependence on fossil exports, or embracing modern technologies. 2/2

The scenarios from both these studies should be in the AR5 db, and include some scenarios that are in the 1.5 range, but I don't know of any like-for-like comparison with newer scenarios

Here is an interesting overview of self reported emission timeseries by US HE institutions:

It would be great if universities also engage more with processes like SBTI or the Oxford offsetting principles:

Carbon neutrality doesn’t always lead to decarbonization. But who is decarbonizing? We looked at >600 US colleges and universities and found 7 that have decarbonized direct (Scope 1) emissions by at least 50% (usually with ground source heat pump networks). This is possible folks! 1/6
