🟢 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. Read more in this thread [1/5]🧵

Because fossil fuel companies often have complex transnational corporate structures, it’s hard to know who really owns them. This lack of transparency also makes it difficult to enforce effective regulation. [5/6]

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. [5/6]

🔸Owner-occupied homes owned by middle income households are more exposed to subsidence. 🔹Second homes often owned by wealthy and diversified households are particularly exposed to flooding. [3/6]

World Inequality Lab @wid.world · 17/07/2025
Single-property owners are highly vulnerable with flood damages representing on average 20% of their total real estate wealth. Owners of rental, second, or vacant properties are the least vulnerable households, flood damages amounting to just about 3% of their real estate wealth. [2/6]

In Spain, there is a clear North/South wealth divide. Madrid stands out for having the highest average wealth levels (€687,000 per household), ≈ 80% > national average. [5/5]

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. [4/5]

Real estate assets dominate household wealth across most of Spain, accounting for just over 50% of the total. Primary residences alone account for over 30%. [3/5]

World Inequality Lab @wid.world · 26/06/2025
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. [3/5]

Children who move at age 13 with their families from a low-opportunity to a high-opportunity area experience a causal effect of around 14% on their adulthood income compared to similar children who do not move. [6/7]

Causal effects of growing up in a better neighborhood explain almost 60% of the geographic variation in upward mobility rates. [5/7]

Intergenerational mobility has declined between people born in the early 1980s and those born in the early 1990s. The 2008 economic crisis hit young people from poorer families especially hard when they entered the job market. [4/7]

World Inequality Lab @wid.world · 18/06/2025
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. 3/7

⚠️Climate change threathens to deepen global inequality: ▪️In a high-impact scenario, the global bottom 50% stands to bear the brunt of climate-related income loss, absorbing 3/4 of total relative income losses. ▪️They could see their income share fall to levels not seen since 1980. [3/3]
First graph shows projections of the global income share a BAU, low-impact and high-impact climate scenario. Second graph shows the share of total climate losses for the bottom 50%, middle 40% and top 10%.

🔹Income convergence won't be enough to fix global inequality by 2050 (BAU scenario) 🔸Taxation won't be enough either. 🔻We need countries to align BOTH their pre-tax (e.g. minimum wage, education, health policies) and post-tax policies with those of the most progressive country in their region. 2/3
