## FAQ
### Do London landlords pay for the ESG premium?
Tenants pay it through rent. The economic case is energy-cost savings + brand value + retention; the strategic case is futureproofing against tightening disclosure regimes.

LEED is the global default occupiers recognise; the local equivalent (BREEAM in the UK, CASBEE in Japan, Green Mark in Singapore) often carries equal or greater regulatory weight.
