What happened

UN: Building Decarbonisation Stalls Despite Efficiency Gains The global buildings and construction sector accounts for more than 10% of global GDP and employs nearly one in 10 people, according to the UN Environment Programme.

Why it matters

However, it is also responsible for more than a third of global carbon emissions and almost half of material use.

Common ground

More than a decade after the Paris Agreement, the sector remains off track to achieve full decarbonisation by 2050.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
