No, the Greens have not declared war on single family homes. That was just the right-wing pitch on the observation by a green politician, that inside dense city regions, there is not enough real estate for single-family houses and that multi-unit houses have a way better energy balance. If you live in a more rural region, feel free to have single-family houses. With an energy-efficient building style and rooftop-solar, that should be very environmently friendly. That is, if you don't waste too much energy commuting. In and directly around cities, there is a huge scarcity of space for buildings and a shortage of homes. Having more dense units is both socially and environmentally friendly.
