Building Automation

Reduced CO2: 5 gigatons
Net cost (Billions US$): $68.12
Net operational savings: $880.55 billion
What do these numbers mean?

TOTAL CO2-EQ REDUCTION (GT)

Total CO2-equivalent reduction in atmospheric greenhouse gases by 2050 (gigatons)

NET COST (billions US $)

Net cost to implement

SAVINGS (billions US $)

Net savings by 2050

Impact:

BAS can result in up to 20 percent more efficient heating and cooling and 11.5 percent more efficient energy use for lighting, appliances, etc. Expanding these systems from 34 percent of commercial floor space in 2014 to 50 percent by mid-century — at an added cost of $68 billion—building owners could save $881 billion in operating costs. 4.6 gigatons of carbon dioxide emissions could be avoided.

Vs

Managed Grazing

Food

Managed grazing imitates the activity of migratory herds to improve soil health, carbon sequestration, water retention, and forage productivity.

Impact:

By enhancing carbon sequestration compared to standard grazing practices, this solution can sequester 16.3 gigatons of carbon dioxide by 2050. Note that this does not reduce the 10 gigatons of methane that are emitted on that grazing land today. Growth in adoption of managed grazing practices would need to rise from 195 million acres to 1.1 billion acres over thirty years. Financial returns are $735 billion by 2050, on a $51 billion additional investment.
