Your child could go to gym class on Monday morning and play soccer on a field that was sprayed over the weekend with 2,4-D, a toxic weedkiller that has been investigated as possibly causing cancer. Alternatively, the school grounds may have been treated with a lower-toxicity weedkiller. Or maybe the grounds were managed with safe, nontoxic products and techniques. Which of these scenarios applies depends in large part on your state’s laws and regulations today – more so than federal regulations. For example, Texas requires all school districts to adopt an integrated pest management program for school buildings; IPM prioritizes nonchemical pest control methods and includes some protections regarding spraying of grounds. Massachusetts also restricts pesticide use on school grounds. Illinois requires IPM for school buildings only if economically feasible. States also vary greatly in the education and technical assistance they provide to implement these practices....

Replacing petroleum fuels with electricity is crucial for curbing climate change because it cuts carbon dioxide emissions from transportation – the largest source of U.S. global warming emissions and a growing source worldwide. Even including the impacts of generating electricity to run them, electric vehicles provide clear environmental benefits. Plug-in vehicles are making great progress, with their share of U.S. car and light truck sales jumping from 2% to 4% in 2020-2021 and projected to exceed 6% by the end of 2022. But sales of gas-guzzling pickups and SUVs are also surging. This other face of the market subverts electric cars’ carbon-cutting progress. As a researcher who studies transportation and climate change, it’s clear to me that EVs provide large carbon reductions that will grow as the electric grid shifts to carbon-free energy. But fleetwide emissions, including vehicles of all types and ages, are what ultimately matters for the climate. Whi...
