Sources of greenhouse gas emissions

Bill Gates has written a book about the environmental crisis called "How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need". It was published in 2021.

The book is structured around two core questions: How bad is the problem, and what do we need to do to solve it? The book breaks down the sources of these emissions, highlighting the main sectors:

  1. Manufacturing (31%): This includes emissions from producing materials like cement, steel, and plastics.

  2. Electricity Production (27%): Primarily from burning fossil fuels like coal and natural gas.

  3. Agriculture (19%): Emissions from livestock, fertilizer use, and other agricultural practices.

  4. Transportation (16%): Emissions from cars, trucks, airplanes, and ships.

  5. Buildings (7%): Emissions from heating and cooling buildings.

And of course, the solution to these emissions is a combination of technologial innovation, government policies and market mechanisms. But the main take away from the book is the granular approach to reducing emissions within each segment and sub-segment of emission
