How does a real estate developer count emissions from flats it sells?

Materials like cement, steel and glass are the developer's purchased goods, Category 1, counted when bought. Contractors' site diesel and power are Scope 3 unless the developer runs the site. Residents' electricity after sale is use of sold products, Category 11, usually estimated over the building's expected life.

Main figures

• Embodied carbon: materials by quantity from bills of quantities.
• Construction: site diesel and electricity.
• Use: expected annual electricity per flat × years × grid factor.

Label assumptions

Category 11 rests on assumptions about use and grid change; state them.

What Senseible does here

Senseible keeps purchase invoices on the Scope 3 trail with the category, method and factor source on every line, so spend-based estimates are labelled as estimates and can be replaced with supplier data later.

• Ready-mix concrete per m3
• Glass facade per sq m
