Amazon’s new environmental report will show how bad two-day shipping is

Amazon.com Inc. announced it will disclose its carbon footprint later this year, giving consumers and investors new insight into the environmental cost of its popular two-day shipping. The company also pledged in a blog post Monday that half of its shipments would be “net zero” carbon—also known as carbon-neutral—by 2030.

The world’s biggest e-commerce company has for years resisted pressure from investors and other stakeholders to disclose more information about its environmental impact. Late last year, several Amazon employees used their stock grants to submit shareholder proposals asking the company to devise and disclose its plans for climate change.
