All companies have these pledges, but they are mostly marketing. These companies know they don't really need to reach those targets, and unless we see massive investment from them to achieve this goal, it just won't happen.
"In an evaluation of some of the world’s largest greenhouse gas emitters, the investor engagement group Climate Action 100+ found no company has fully disclosed how it plans to reach net-zero."
"Some of the boldest pledges rely on carbon removal technologies that don’t even exist yet, or at least not at the scale required. Many more are heavily reliant on carbon offsets, which allow companies to invest in “nature-based” programs like tree planting or forest protection to counteract their own emissions. Offset projects, however, have been plagued by allegations of flawed accounting, greenwash and sometimes even of actively fueling climate change."

That is, they say they'll do something, but they don't even know how, or at least won't tell for some reason... meaning that there's no way to check if they're doing the necessary work or mostly fugding with the numbers (some high profile cases where companied just patently fabricated numbers regarding their progress have already been revealed in the news).
I believe there's zero indication that companies are serious... emissions in 2023 are set to be the highest ever recorded (and this is not because of higher emissions in developing countries, the developed world is still leading the shameless business-as-usual route)... that's in the middle of a global economical crisis... imagine if the economy had been doing really well!
Until actual emissions start to fall dramatically, don't believe in these companies empty promises.
