Telepresence

Transport

Telepresence integrates high-performance visual, audio, and network technologies to enable people who are geographically separated to interact. By reducing travel, it can reduce emissions.

Telepresence

Reduced CO2: 2 gigatons
Net cost (Billions US$): $127.72
Net operational savings: $1,310.59 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:

By avoiding emissions from business air travel, telepresence can reduce emissions by 2 gigatons of carbon dioxide over thirty years. That result assumes that over 140 million business-related trips are replaced by telepresence in 2050. For organizations, the investment in telepresence systems pays off with $1.3 trillion worth of savings and 82 billion fewer unproductive travel hours.

Green Roofs

Buildings and Cities

Green roofs use soil and vegetation as living insulation. Cool roofs reflect solar energy. Both reduce building energy use for heating and/or cooling.

Green Roofs

Reduced CO2: 1 gigatons
Net cost (Billions US$): $1,393.29
Net operational savings: $988.46 billion

SAVINGS (billions US $)

Net savings by 2050

Impact:

In modeling green and cool roofs, we account for regional applications of each technology. If green roofs cover 30 percent of roof space by 2050 and cool roofs cover 60 percent, a total of 407 billion square feet of efficient roofing would be in place globally. Combined, these technologies could reduce carbon dioxide emissions by 0.8 gigatons at a cost of $1.4 trillion, thirty-year savings of $988 billion, and lifetime savings of $3 trillion.
