About these figures

Price change: Median price in the last 12 months against the 12 months before.
Sales a year: Open-market sales in the last 12 months. More sales means a deeper, easier market.

Carbon: Average carbon emissions of homes sold, tonnes a year. Lower is better.
Station nearby: Median distance from homes sold to the nearest railway station. Closer is better.
