This document discusses low carbon transportation, power plant, and shipping technologies that can reduce GHG emissions and lower costs. Key points: 1) Technologies like more fuel efficient vehicles, higher speed rail, and faster shipping vessels can achieve the same work with 33% less fuel and engine volume, lowering emissions. 2) Improvements in fuel efficiency of 9x kmpl for rail and shipping can reduce CO2e emissions by 11.1% per ton-km or kilometer. 3) Power plants using the same fuel but with more efficient rotary engine technology could generate the same electricity using 33% less coal, lowering CO2e emissions to 233g/kWh. 4) Many
