Study: Climate benefits of proposed carbon dioxide mitigation strategies for international shipping and aviation (2019)

Hello!

I recently came across this interesting study published by the Environmental Defense Fund in 2019. “Climate benefits of proposed carbon dioxide mitigation strategies for international shipping and aviation”. The researchers/authors of this study demonstrate that the global CO2 emissions from shipping and aviation would contribute to a rise of 0.12 degrees Celsius to the global temperature rise, by 2100 combined, if no mitigation measures are taken. The remaining “allowable warning” by 2100 is 0.5 to 1.0 degree Celsius, considering that the global temperature is already 1 degree higher compared to the “pre-industrial” levels.
The study suggests that mitigation measures and policies could potentially reduce the contribution of global warming from shipping and aviation by 85%. This raises an important question:
What actions are other, more polluting, sectors taking to mitigate their contributions to global warming?
