Exploring Sustainability Commitments of the Top 5 Companies in the S&P 500

The S&P500 is a list of the top 500 largest companies that are traded on the stock market.

The top ten of these companies represents major aspects of the global and especially the domestic economy. These brands pump out billions of dollars in product and manufacture things that are present in almost every home in the country. Although this widespread acceptance is almost universally known, much of the public has no idea how sustainable these companies are. Even though they often produce and publish annual sustainability documents, most people don't know how to read them.

However, by learning where to find these documents and how to read them more effectively, the public can make smarter choices about where to invest money and extend this information awareness into other areas of life. By making smarter and wiser choices, sustainability can be achieved.

Greenisms.com intends to make sustainable choices more realistic, obtainable, and socially achievable for everyone!

• Amazon’s reporting is aligned with common sustainability frameworks, although it has faced criticism for not meeting Science-Based Targets Initiative (SBTi) requirements and for backtracking on certain pledges, such as Shipment Zero7.

  
  

Continuous Improvement and Accountability

• Teams across Amazon are accountable for setting decarbonization plans that align with the global strategy, with annual tracking and public disclosure in the company’s sustainability report101.

• Amazon uses a science- and data-driven approach to measure progress and improve sustainability performance year over year102.

  
  

Criticisms and Challenges

• Despite progress in renewable energy and packaging, Amazon’s Scope 1 emissions (transportation) continue to rise, and critics argue that its net-zero by 2040 target is not aggressive enough given the scale of its operations and the urgency of climate action7.

• The company has also been called out for not submitting detailed emission-reduction plans to the SBTi and for canceling certain public pledges7.
