U.S. GDP is up nearly 140% since 1990 while emissions are barely up

GDP is adjusted for inflation in the graph below 

See this related post Chart of the day: In 2014, the US economy was more than twice as energy efficient (‘green’) as in 1970 when Earth Day started.

"the US economy was 28% larger last year than 14 years ago, even though slightly less total energy was required in 2014 than in 2000 (98.324 vs. 98.819 quadrillion BTUs) to produce $3.5 trillion more real output. That would be like adding an economy about the size of Germany’s to the US, but without requiring any additional energy to produce 28% more output!"

"since 1949 the size of the US economy has grown by a factor of 8 times, from $2.0 trillion in real GDP to $16.1 trillion in 2014. But over that time period, the annual amount of energy consumed in the US has increased by a factor of only 3 times"

"Compared to 1970 when the first Earth Day was celebrated and 14,400 BTUs of energy were required for every dollar of output, the energy efficiency of the US economy has more than doubled – we use less than half that amount of energy today (6,110 BTUs) for every dollar of output" 

Also see this speech by Governor Donald L. Kohn in 2006. 

"Since the 1970s, the energy intensity of production in the United States has fallen dramatically; indeed, on an inflation-adjusted basis, it takes roughly half as many Btu of energy to produce a dollar of GDP today than it did at the time of the 1973 oil crisis"

Also see this chart Energy intensity in the USA from Our World in Data.

"Energy intensity is measured as primary energy consumption per unit of gross domestic product (GDP), in kilowatt-hours perdollar. GDP is adjusted for inflation and differences in living costs between countries."

In 1965 it took 3.47 kilowatt-hours to produce a dollar of GDP in the USA. In 2022 it was just 1.36 kilowatt-hours. That is about a 60% drop. Using less energy means fewer emissions.
