The McKinsey for Vattenfall Report “A Cost Curve for Greenhouse Gas Reduction” investigates popular greenhouse gas reduction strategies and their related costs. Almost a quarter of possible emission reductions would result from measures that carry no net life cycle cost – in effect, they come free of charge. Most of those measures are related to building design (building insulation, lighting, air conditioning).

Emissions from buildings are responsible for 40% of all global emissions, on the other hand buildings offer huge possible efficiencies and low cost abatement strategies. This should inform us as building industry representatives as well as governments responsible for the rules of the game.

It is a myth that addressing greenhouse gas emissions will severely strain the global economy: The authors point out that the cost of emissions abatement would be 0.6%–1.4% of the global GDP, it can be compared with the amount spent globally on insurance, which is 3.3% of the global GDP.
