Trains

Transport

Most trains are powered by diesel-burning engines. Technology and operations can improve fuel efficiency, and rail electrification has the potential to provide nearly emissions-free transport.

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:

Globally, electrification of rail comprises 166,000 miles of track length. If that increases to 621,000 miles by 2050, emissions from fuel use for freight operations alone can be reduced by 0.5 gigatons of carbon dioxide. This additional electrification could cost $809 billion, saving $314 billion over thirty years and $775 billion over the lifetime of the infrastructure. Prioritizing high-usage corridors can lower net costs.

Educating Girls

Women and Girls

Education lays a foundation for vibrant lives for girls and women, their families, and their communities. It also avoids emissions by curbing population growth.

Impact:

Two solutions influence family size and global population: educating girls and family planning. Because the exact dynamic between these solutions is impossible to determine, our models allocate 50 percent of the total potential impact to each. We assume that these impacts result from thirteen years of schooling, including primary through secondary education. According to the United Nations Educational, Scientific, and Cultural Organization, by closing an annual financing gap of $39 billion, universal education in low- and lower-middle-income countries can be achieved. It could result in 59.6 gigatons of emissions reduced by 2050. The return on that investment is incalculable.
