"Cement and concrete production accounts for about 8% of global carbon dioxide emissions, which is twice as much as in 1990 due to increased construction worldwide. The surfaces under your patio, walkway, or driveway contribute to this, especially when rainwater runs off instead of soaking into the ground."
"Two environmental problems converge underfoot. The first is embodied carbon. Cement is responsible for roughly 90% of concrete's carbon emissions, and the world produced more than 4 billion metric tons of it in 2022. The second is stormwater. Conventional impervious paving funnels rain into storm drains, picking up oil, metals, and tire residue along the way. Permeable pavement can reduce surface runoff by up to 85% compared to traditional pavement, and EPA-monitored studies have documented removal efficiencies of 82-95% for sediment, 65% for total phosphorus, and 80-85% for total nitrogen."
"Some U.S. cities now require a certain amount of permeable paving in new parking lots and walkways. Many also offer stormwater fee credits or tax incentives for homeowners who install permeable surfaces. Before starting your project, check with your local stormwater utility. You might be able to save money."
"Using reused materials is still the most environmentally responsible choice. Salvaged brick, reclaimed flagstone, and broken co"
Cement and concrete production accounts for about 8% of global carbon dioxide emissions, rising since 1990 due to increased construction. Impervious patio, walkway, and driveway surfaces increase stormwater runoff instead of allowing infiltration. Conventional paving sends rainwater into storm drains while carrying pollutants such as oil, metals, and tire residue. Permeable pavement can reduce surface runoff by up to 85% and has documented removal efficiencies for sediment, total phosphorus, and total nitrogen. Some U.S. cities require permeable paving in certain projects and offer stormwater fee credits or tax incentives for homeowners. Local stormwater utilities can provide guidance and potential savings. Reused materials remain the most environmentally responsible option, including salvaged brick and reclaimed stone.
