In a Medium post Wednesday published by a group called Amazon Employees for Climate Justice, more than 3,500 staffers urged CEO Jeff Bezos to publicly outline the company’s plans to reduce carbon emissions and reliance on fossil fuels.

The letter follows two meetings between Amazon (AMZN) leadership and employees that delivered little clarity on the company’s efforts, Rajit Iftikhar, an Amazon software engineer who co-signed the letter, confirmed to CNN Business.

Amazon has vowed to become more sustainable in the coming years in an effort called Shipment Zero to make all packages net zero carbon and 50% of all shipments net zero by 2030.
