You do need a yard if you want to do outdoor composting, or you don't need one if you want to do it in your home by using worms!
You can participate in curbside composting if you live in an NYC community board that's eligible for the weekly organic waste collection service. As of today, here are the eligible community boards for the service:

• Brooklyn 1 (Williamsburg, Greenpoint)
• Brooklyn 2 (DUMBO, Downtown Brooklyn, Fort Greene, Clinton Hill, Brooklyn Heights)
• Brooklyn 6 (Red Hook, Gowanus, Carroll
  Gardens, Park Slope)
• Brooklyn 7 (Sunset Park, Industry City, Windsor Terrace, South Slope)
• Manhattan 6 (Stuy Town & Peter Cooper Village, Midtown East, Murray Hill)
• Manhattan 7 (Manhattan Valley, Upper West Side, Lincoln Square)
  Bronx 8 (Kingsbridge, Riverdale)
• All community boards in Queens will be eligible for the service starting on 3/27.

If you live outside of those community boards, you can collect your food scraps and bring them to Food Scrap Drop-Off (FSDO) sites or our Bigbelly™️ Smart Bins that are peppered throughout the city. You can look them up at nyc.gov/dropfoodscraps. Please be mindful of the operating hours for FSDOs and the app instruction for Smart Bins (Smart Bins don't open when they are full!).
