Because if we removed 3.5% of emissions today, it would take us right back to where we were roughly just 2 years ago.
We need to clean up the energy sector first. That’s roughly 80% of emissions. Agriculture is the next big one at 10%.
Aviation is by far the hardest sector to clean up and would make the least impact. Energy is the easiest AND makes the biggest impact on total emissions and climate change.
Going to green energy production like wind, solar, hydro, and nuclear, and making the energy sector entirely emissions free would reset out total emissions back to over 100 years ago.
