Corporations hold significantly more responsibility for greenhouse gas production than do individuals. In fact, as few as 90 companies cause as much as two-thirds of global emissions. That share also represents the magnitude of impact corporations can have on reducing greenhouse gas production – by going green themselves thereby influencing the economy towards clean energy.

So far (July, 2019), 185 companies listed in RE100’s list of companies, have pledged to go 100% renewable. Some intend to reach their goals are as early as 2020, some as late as 2050. Some of their goals are for carbon neutrality (meaning they have committed to producing as much renewable energy as they consume) and some goals are focused on sourcing 100% renewable electricity for portions or all of their business needs.

These companies are taking action to become renewable through their production, their infrastructure and/or their transportation. They are conserving, reusing, replacing and/or recycling in one commendable manner or another. 

As you investigate the RE100 list or the manufacturers on this page, you may find companies missing, despite their remarkable strides to mitigate global warming, in specific categories. Look here for: 

  • Companies specifically focused on investments or divestment or insurance are in the ECONOMICS section
  • Utilities or other energy companies, promoting or facilitating clean energy, are in the ENERGY section
  • Companies solely focused on waste, trash or recycling are in the WASTE section.
