Recycling + Composting = Not Driving
New research shows that a household recycling all of its readily recyclable and compostable waste reduces greenhouse gas emissions as much as if they stopped driving their cars.
Climate Cooling Benefits of Recycling & Composting

Gasoline & Diesel: capturing 100% of household curbside recyclable materials equivalent to 60% cut in household vehicle fuel & oil use.
Electricity: capturing 100% of household curbside recyclable materials equivalent to 10% cut in household electricity use.
Meat & Dairy: capturing 100% of household curbside recyclable materials equivalent to 100% cut in household meat and dairy consumption.

Gasoline & Diesel: capturing 100% of household compostable materials equivalent to 30% cut in household vehicle fuel & oil use.
Electricity: capturing 100% of household compostable materials equivalent to 5% cut in household electricity use.
