Emissions of Carbon Dioxide in the Transportation Sector, Motor Vehicle Miles Traveled, and Emissions per Mile Traveled by Light-Duty Vehicles Measured as a Percentage of Their Value in 1975 - Transportation sector emissions have not risen nearly as much as vehicle miles traveled because gains in fuel economy have reduced emissions per mile of travel.

Comment: Americans go above and beyond anything suggested, even if the goal is to improve things. Americans in particular, and humans in general like "quick fixes" that don't disrupt their lives and approximate what they're used to doing already. Lithium is an energetic element, number 3 on the Periodic Table, following Hydrogen and Helium. Its properties as an anode are why we use the element in battery technology. It's now "trendy" to own an Electric Vehicle, when during the pandemic (see the dip above in Fig. 10 from the CBO report), the simplest solution - at least short term - would be to drive less. This might entail telework agreements to come into the office on set days in a pay period. It could also mean an infrastructure centered around public transportation, Maglev trains such as in China, Japan, and Korea. A longer-term solution would be a total revision of what we regard as capital, earnings, and quarterly profits, which seem shortsighted and not strategically positioned for the global environment or species survival.
Lithium is an essential component of clean energy technologies, from electric vehicles (EVs) to the big batteries used to store electricity at power plants. It is an abundant mineral, but to be used it must be extracted from the earth and processed.
Today, there are two main ways to pull lithium from the ground. Until recently, most lithium mining occurred in Chile, where lithium is extracted from brines: salty liquid found at the Earth’s surface or underground. To extract lithium, that liquid is pumped from the earth and then placed in pools where the water can evaporate, leaving behind lithium and other elements.
Elsewhere, lithium mining looks more traditional. In 2017, Australia overtook Chile as the dominant lithium producer. Companies there blast a lithium-rich mineral called spodumene out of open pits. Today, Australia produces roughly half of the globe’s supplies.1 More than 80 percent of that rock then travels to China, where it’s further processed to yield lithium.2
Though Australia and Chile dominate production, the rise of clean energy has spurred a growing hunger for lithium, so other mining operations have cropped up in numerous other places. Global lithium production has grown from about 37,000 tons a decade ago to 130,000 tons in 2022.1,3
“We've just seen an explosion of proposed projects in the planning, piloting, demonstration stage across a much wider array of countries,” says Caroline White-Nockleby, a PhD candidate who studies renewable energy transitions in MIT’s doctoral program in History and anthropology; and Science, Technology, and Society.
