The 'Paris Proof indicator' refers to a metric used to assess whether a building or project aligns with the goals of the Paris Agreement, an international treaty aimed at limiting global warming to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit it to 1.5 degrees Celsius.

The Paris Proof indicator evaluates the environmental performance of buildings or projects based on their greenhouse gas emissions, energy efficiency, and overall sustainability practices. It aims to ensure that buildings and projects are designed, constructed, and operated in a way that contributes to global efforts to mitigate climate change and reduce carbon emissions.

Meeting the Paris Proof standard typically involves implementing energy-efficient building design, utilizing renewable energy sources, reducing energy consumption, optimizing material usage, and minimizing carbon emissions throughout the building's lifecycle. Buildings or projects that meet the Paris Proof criteria are considered to be aligned with the goals of the Paris Agreement and are contributing to global climate action.
