I am disappointed that I was not reappointed for another term, but I understand that they could not have two white males from the same institute in the panel. Congratulations to the new members! I hope they will really put in the 1 day/week they have committed to!

House prices are exploding, making moving unaffordable and driving inflation. EE identifies the move by financial investors into the housing market, and rising wealth inequality as major causes. Limit billionaires' market access to support housing affordability and fight inflation.

How can we get empty-nesters to move to smaller flats and make their residences available to young families? This is what we need to do to address the housing shortage with paving over more green spaces.
Want to cut your carbon footprint? Move out of your house
There’s no getting around it: downsizing the kind of housing you live in is the best thing you can do for the environment.

Some jurisdictions have made a real effort and it shows in the numbers. This is a demonstration that mitigation is possible, countering the “we can’t do anything about it” narrative. Therefore it is so important.
The UNEP GAP report is not the kind of reading that makes climate scientists smile. But this figure is not all bleak - look at all the emissions curves pointing downwards!
