We estimated CO2 emissions from residential heating in Germany at 100 m resolution, using #opendata. Cities emit most in total but often less per person than rural areas. Over half of homes predate 1979 & 80% heat with gas, oil, coal or wood, so switching could cut emissions fast. 👉 buff.ly/a9lQqbl
