Actions that are cost-effective under current climate conditions, are consistent with addressing risks of climate change and possess no hard trade-offs with other policy objectives.

Technology for reducing greenhouse-gas emissions whose other benefits (in terms of efficiency or reduced energy costs) are so extensive that the investment is worth it for those reasons alone. For example, combined-cycle gas turbines – in which the heat from the burning fuel drives steam turbines while the thermal expansion of the exhaust gases drives gas turbines – may boost the efficiency of electricity generating plants by 70 per cent.
