To help mark its progress, Amazon plans to publish its overall carbon footprint later in 2019. The company has been creating an "advanced scientific model" to both map that footprint and give individual teams information they can use to reduce their carbon output.

It's a significant step, and one that will likely have an impact on society given Amazon's dominance of online shopping in some countries. However, this doesn't address some of Amazon's outstanding environmental problems. Earlier in February, Greenpeace published a report indicating that the company had dramatically increased its Amazon Web Services operations in Virginia without adding more renewable energy. It's actually contributing to emissions by increasing demand for fossil fuel energy in the state. While Amazon has vowed to eventually run completely on renewable energy, it won't get there until it's making improvements in every category, not just the ones customers are most likely to notice.
