Microsoft Corp said on Thursday it would take out of the atmosphere as much carbon as the company had ever produced, joining US tech giants in setting ambitious goals for combating climate change.
Below is a snapshot of the promises and achievements US West Coast tech companies have made in the area:
Microsoft said it would be carbon negative by 2030, and that by 2050 it hopes to have sequestrated enough carbon to account for all the direct emissions the company has ever made.
The Windows operating system maker said it would fund the program with an internal carbon fee, and that its new climate innovation fund would invest $1 billion over the next four years into new technologies to reduce its carbon footprint.
Microsoft expects to generate 16 million metric tons of CO2 in 2020, including indirect emissions from activities like corporate travel.
The iPhone maker last March said that it had reduced carbon emissions by 64 percent since 2011, preventing 2.8 million metric tons of CO2 from entering the atmosphere.
It also said it had doubled the number of suppliers using only clean energy for production and was on track to add 4 gigawatts of renewable energy to the power used by its supply chain by 2020.
In December, Apple bought the first-ever commercial batch of carbon-free aluminum from a joint venture between aluminum suppliers Alcoa Corp and Rio Tinto, to be used in Apple products.
Apple's global facilities, including retail stores, offices and data centers across 43 countries use 100 percent renewable energy, it had said in 2018.
Amazon Chief Executive Officer Jeff Bezos has pledged to make the e-commerce giant net carbon neutral by 2040 and has said it will buy 100,000 electric delivery vans from US start-up Rivian.
Cutting emissions is a challenging goal for Amazon, which delivers about 10 billion items a year and has a massive transportation and data center footprint.
In September, Bezos said that Amazon would use 100 percent clean energy by 2030, up from 40 percent.
Alphabet Inc's Google has vowed to neutralise carbon emissions from delivering consumer hardware by 2020 and include recycled plastic in each of its products by 2022.
The search giant said in August its transport-related carbon emissions per unit fell 40 percent in 2018 compared to 2017 by relying more on ships instead of planes to move hardware from factories.
In September, the company said it reduced its greenhouse gas emission by 3.7 million tons to 750,000 tons of CO2 in 2018. The company says it has cut carbon emission by 52 percent since 2011.
Google bought enough renewable energy to match 100 percent of its global annual electricity use in 2017 and 2018, it said last year.
Facebook Inc said last year it was committed to reducing its greenhouse gas footprint by 75 percent from 2017 levels next year and to using 100 percent renewable energy in 2020.
A report by the social network shows that it has reduced greenhouse gas emissions by 23 percent to 339,000 metric tons in the four years since 2014.
