Intel details its carbon emissions in annualcorporate responsibility reports.

That’s equivalent to the emissions produced by more than 646,000 cars each year.

Intel’s net zero pledge comes after other tech giants have committed to reduce carbon emissions.

Google says it’salready eliminated its carbon legacy.

To reduce their climate impact, Intel often burns such gases, says Chief Sustainability Officer Todd Brady.

But that still releases carbon dioxide.

The company will push the industry to research and adopt different chemistries for semiconductor manufacturing, he said.

Replacing PFCs likely will take a decade, he said.

Cutting greenhouse gas emissions is crucial to combat climate change.

Some technology companies likeClimeworks,Charm IndustrialandCarbonCapture, want to go further bycapturing carbon dioxide from the air.

Intel will cut its direct emissions in other ways.

Chips and Climate Change

Reducing a company’s climate footprint is complicated.

Intel’s net zero pledge is aimed only at scopes 1 and 2.

The company is working on Scope 3, though, by improving the energy efficiency of its products.

It already ranks suppliers in part by scoring their sustainability efforts.

Scope 3 emissions are a big deal.

The overall work is expensive but necessary, Brady said.
