Welcome the future building emissions calculator. This interactive website presents an interactive model that estimates future carbon emissions of the global building stock until 2050 for three scenarios, Business as usual Operational Carbon Operational Carbon and Embodied Carbon. The latter two scenarios are alternative, user-defined futures to the Business as usual scenario that are based on four assumptions that can be set by the user:

(1) Carbon budget based on global emission scenario based on one of five shared socioeconomic pathways (SSP).

(2) Global annual building renovation rate by 2050

(3) Year by which all new construction is carbon neutral in terms of operational energy use.

(4) Year by which all new construction is carbon neutral in terms of embodied energy use.

More information regarding these inputs are provided below. Model outputs show resulting annual carbon emissions until 2050 as well as whether a scenario manages to stay under carbon budget set by the IPCC. The purpose of the calculator is to provide a sense of the enormity of the task of making the global building stock carbon neutral over the coming decades…

(Global floor areas and operational emissions are based on projections by the International Energy Agency. The carbon budget and emissions scenarios are based on SIMP6 Pathways. For more information please refer to our full report http://dx.doi.org/10.2139/ssrn.3939009)
