World’s largest chip foundry TSMC sets 2050 deadline to go carbon neutral:
The dirty secret of the computing and networking world is that most of its pollution comes not from the electricity used to run the devices, but from the energy and materials used to produce the chips that make it all possible.
In a typical laptop like a MacBook Air, manufacturing represents 74 percent of the device’s lifetime carbon emissions, including shipping, use, and disposal. Of that, about half is from integrated circuits, according to a recent study led by researchers at Harvard. Researchers have found similar trends throughout the industry. “Chip manufacturing, as opposed to hardware use and energy consumption, accounts for most of the carbon output attributable to hardware systems,” the study’s authors said.
That footprint may wane in the coming years, though, as TSMC announced last week that it would flatten its emissions growth by 2025 and reach net-zero carbon by 2050. That’ll be a tall order for a company that produced over 15 million tons of carbon pollution last year across the entire scope of its operations, about the same as the country of Ghana. Though the amount of carbon pollution per wafer produced by TSMC has declined in recent years, surging demand for semiconductors has driven overall emissions up, and years of rising energy use, likely from the introduction of EUV lithography, has slowed progress.
[...] To achieve the net-zero goal, TSMC will have to work hand in hand with the Taiwanese government. The company uses 4.8 percent of the island’s power today, a figure that’s expected to rise to 7.2 percent by 2022 when the 3 nm fabs are turned on, according to Greenpeace Taiwan. Currently, Taiwan is heavily reliant on coal and natural gas, with less than 20 percent of electricity produced by nuclear and renewables. [...]
To put that 15 million tons into perspective, that's more than some small countries.

I think you are being naive here. Official numbers might indicate low or no inflation, however, they certainly only reflect a narrow spectrum of the economy. A forteriori, inflation calculations have been tampered with for a long time (hedonic calculation). It is true that due to low wage increases, inflation as measured has not increased much (e.g. food), however, in other areas there has been huge inflation. Most notably real estate and shares. You can postpone buying a home but eventually you will make the purchase which means that inflation (as measured) will catch up.
To connect it to threats is a false dichotomy. There is no threat. There is only great social injustice in that people owning shares and real estate are protected from inflation while the rest is not. One would like to be fiscally conservative to be socially progressive.
