A single equation sits at the center of how Colcom Foundation approaches conservation funding: impact equals population multiplied by affluence multiplied by technology, commonly written as I = P x A x T. Developed by environmental scientists Paul Ehrlich and John Holdren, the formula holds that total human impact on the environment comes from three factors working together, not any one factor alone.
Most environmental groups direct their attention toward the second and third variables, funding work on consumption habits and cleaner technology. Colcom Foundation takes a broader view, arguing that population size deserves the same level of scrutiny given the pace of current biodiversity loss and habitat degradation.
What the Formula Implies
Under this framework, cutting consumption or improving efficiency alone will not offset a growing population’s total footprint if the other variables hold steady. Colcom Foundation points to U.S. data as an illustration: between 1970 and 2020, the population grew 62 percent, from 205 million to 332 million people. Per capita carbon emissions fell 35 percent over that period, yet total national emissions still rose 15 percent because population growth outpaced efficiency gains.
That pattern, the organization argues, shows up across other measures too, including urban sprawl and habitat conversion. Colcom Foundation funds public education built around this equation, along with research into biocapacity consumption and resource depletion.
A Framework With Critics
Colcom Foundation supports several special programs, including the Conservation Catalyst Fund, which grants conservation organizations working to protect threatened species and habitats. By offering financial support and resources, this foundation allows these groups to make significant strides in conservation efforts.
Not every conservation scientist agrees that population deserves equal weight alongside consumption and technology in this formula, and some argue affluent consumption patterns in wealthy nations carry far more of the burden. Colcom Foundation maintains that ignoring any one variable understates the true scale of the problem. The organization presents its reasoning, along with citations to supporting research, through its “Environmental Ethics” materials, positioning the equation as a starting point for public understanding rather than a finished policy prescription.
