A mental model for combatting climate change
Visualize how we will get to net zero greenhouse gas emissions over time to stay under 1.5C?
How much greenhouse gases (CO₂e) do we emit globally each year (2020)?
What are the three key areas of de-carbonization?
Electrification, agriculture, heavy industry
The 3 steps to increase carbon removal to 10Gt/year are:
1: Develop a portfolio of low-cost carbon removal solutions, 2: Create large, predictable demand, 3: Create markets to match high-quality supply with demand
Electrifying everything will reduce global GHG emissions by
16.5Gt (with clean power)
How much GHG (CO₂e) do we emit in the process of extracting hydrocarbon fuels?
About 7.5 gigatons (15%)
What are three key steps to electrify everything?
Electrify the machines, flood the grid with clean energy, deal with increased demand and more variable supply
Electrifying everything (short of heavy industry) means addressing what household appliances?
vehicles, heating / cooling, stoves
We won't just need to replace the grid with clean power, we will need to produce a lot more to deal with electric machines
How much GHG (CO₂e) do we emit to produce food (minus transportation, refrigeration, etc.)?
The two steps needed to decrease GHG emissions from agriculture are:
use a lot less land + decrease fugitive emissions from livestock and soils
Cutting down forests is called
Re-growing forests is called
