🟢 Planned new oil, gas, and coal extraction alone could exhaust the 1.7°C carbon budget — This is one of the key findings presented in *Chapter 1.2 of the 2025 #ClimateInequality Report* outlining the scale of ongoing investments projects.

Unlike owner-occupants, owners of rental, second, and vacant homes don’t factor natural disaster risks into prices.
Absentee landlords own about half of all homes in flood-risk areas.
Overvaluation in flood zones would drop at least 15% if these properties were priced like owner-occupied ones.

The asset portfolio changes a lot depending on the wealth level of households:
🔹For the bottom 20%, current accounts are the most relevant asset, ≈ 60% of their portfolio.
🔹For the top 10%, investment properties, business assets, and especially equities and investment funds are more important.

In Spain, like everywhere in the world, wealth distribution is much more unequal than income.
The top 1% accumulates a quarter of the wealth; the top 10%, 60%.
This is more or less in line with neighboring countries.

Spain ranks in the lower-middle range in international comparisons of intergenerational mobility.
In Spain, only 10% of children from the bottom 20% reach the top 20%, while over 60% of those born in the top 20% remain in the top half.
It’s slightly better than the US, but not as good as Sweden.
