Urban densification is definitely more eco-friendly than most suburbanization. The emissions of cars for the US is much higher than most people expect at 1.7 billion tons, while air conditioning is about 117 million tons. A/C also peak matches solar, which makes the emissions for it easier to cut. Heat is harder to get numbers on, but I also think most oversized suburban houses are in the sunbelt these days, plus I don't think a home office swings it too much from the baseline heating to keep the pipes from freezing.
