Inspiring and equipping the world’s wealthiest to lower their carbon footprints by 5% annually.

Bar graph titled 'Annual Carbon Emissions (per capita)' showing three groups: Bottom 50%, Top 10%, and Top 1%. The Bottom 50% has nearly zero emissions, the Top 10% emits about 32 times more, and the Top 1% emits about 103 times more, with annotations indicating '32x bottom 50' and '103x bottom 50'.

The 5% Pledge began with a question: What if the world’s wealthiest 5% did their part to lead the world toward our climate goals?

You might assume this group only includes billionaires, but the reality is surprising. If you are a middle-class American, you are likely part of this global 5%.

Currently, this group has a carbon footprint 40 times larger than the world’s poorest 50%. We believe this means we have the greatest power to make a change.

Together let’s learn what it means to be carbon literate, apply it to our consumption habits, to our large institutions, and to our investments.
