Earth Pledge's Limit 450 initiative was created to limit carbon to 450 parts per million in the atmosphere, and help avoid the devastating effects of climate change.

As carbon emissions increase due to human activities, and as northern permafrost melts, rotting organic matter is releasing carbon dioxide and methane into the atmosphere. This vicious cycle threatens the stability of weather patterns worldwide.

Our Limit 450 initiative works directly with farmers across the country to support their carbon mitigation and sequestration practices. First, farmers are educated and encouraged to reduce their own carbon emissions. We then help them institute sequestration practices they can sell as offsets - helping others to achieve carbon neutrality.

Together, we can contain achieve carbon neutrality.
