Sept 12 (Reuters) - Amazon.com ( AMZN ) has been testing

General Motors' ( GM ) BrightDrop electric van, as the

e-commerce giant continues to explore options to reduce carbon

emissions of its wide-spread delivery operation, Bloomberg News

reported on Friday.

The company has been testing about 12 vans, placing them

among a fleet that also includes vehicles built by Rivian

and Ford, according to the report.

Both Amazon ( AMZN ), which is Rivian's largest investor with a 16%

stake, and GM did not immediately respond to Reuters' requests

for comment.

The e-commerce company has committed to have at least

100,000 electric delivery vehicles on the road by 2030 and to

reach net-zero carbon across its global operations by 2040.

GM has halted the production of the Chevrolet BrightDrop

electric vans, launched in 2021, at its assembly plant in

Ontario until October due to slow sales.
