March 13 (Reuters) - Carbon capture firm 1PointFive said

on Wednesday telecom company AT&T ( T ) has agreed to purchase

carbon dioxide removal credits as part of its goal to reduce

emissions and become carbon neutral in its global operations by

2035.

1PointFive is the carbon capture, utilization and

sequestration unit of oil and gas firm Occidental Petroleum ( OXY )

. AT&T ( T ) will buy the credits from 1PointFive's Stratos, a

direct air capture facility that is currently under construction

in Texas.

AT&T ( T ) and 1PointFive did not disclose the financial details

of the agreement.

Carbon credits are tradable permits that allow the owner to

emit certain amounts of greenhouse gases. Each credit permits

the emission of one metric ton of carbon dioxide or the

equivalent in other greenhouse gases.

Stratos is designed to capture up to 500,000 metric tons of

carbon dioxide annually when fully operational.

1PointFive had earlier announced carbon credit agreements

with companies such as Amazon ( AMZN ), Boston Consulting Group

and Trafigura, among others.
