Every time I clean a yogurt container I feel torn. What is a better environmental trade-off: not running water for 90 seconds or recycling the plastic? I think it would be really helpful if there was some kind of universal unit that would describe the real environmental impact of producing, trashing, recycling of goods and materials. The unit would appear on packagings of goods, specs of materials, landfill/recycling bins etc. I created a pdf to visualize the idea (all values in the pdf are made up): https://www.dropbox.com/s/rdi51serx6hwn8e/EarthHarm.pdf?dl=0 I realize how complex such a project would be. Inherently, the choice of how the unit works would be a political one. How to compare and calculate the different environmental challenges and wrap them up in one unit? What institution would have enough authority and expertise to deploy it? Setting this all aside, I think unit like this would be a really helpful tool letting people have some baseline they can refer to. It could inform people what is the impact of their actions and where to seek for a real change. (a simpler version of this project would be a well-researched website that compares these environmental factors with each other)
