<strong>Energy</strong> Demand by Sector<br />

CO 2<br />

emissions from direct combustion of fossil fuels in end uses and other<br />

transformation other than power generation are reduced to 16.2 Gt in 2030<br />

– 3.3 Gt, or 17%, lower than in the Alternative Policy Scenario. <strong>Energy</strong><br />

savings by sector in 2030, over and above those achieved in the Alternative<br />

Policy Scenario, assume that best-practice commercial technologies available<br />

are quickly and widely deployed where the potential costs less than $50 per<br />

tonne of CO 2<br />

(IPCC, <strong>2007</strong>). Taking into account the carbon content of crude<br />

oil, this is equivalent to an increase in oil prices of $18 per barrel.<br />

The use of fossil fuels in industry is reduced by 18% in 2030 compared with the<br />

Alternative Policy Scenario, yielding 1.3 Gt of CO 2<br />

savings. The biggest savings<br />

are in the iron and steel and cement industries. Widespread adoption of bestpractice<br />

technology, which is already commercial, or will become so, would<br />

allow this potential to be harvested (IEA, <strong>2007</strong>a). In practice, financial<br />

incentives or regulations would be required to ensure that less efficient<br />

equipment is retired early. Electricity savings in less energy-intensive industries<br />

and improved motor efficiency are already fully exploited in the Alternative<br />

Policy Scenario. Therefore, we do not assume any additional electricity savings<br />

in the industrial sector above those in the Alternative Policy Scenario.<br />

Equipping some refineries, ammonia, cement and iron and steel plants with<br />

CO 2<br />

capture and storage (CCS) brings about an additional reduction of<br />

0.5 Gt. Strong policies, such as regulations or subsidies, would be required for<br />

this to happen.<br />

In the residential and services sector there is only limited remaining potential to<br />

reduce coal, oil and natural gas direct use beyond the level achieved in the<br />

Alternative Policy Scenario. Additional fossil-fuel savings amount to 7%,<br />

yielding savings of 0.3 Gt of CO 2<br />

. Increased electricity savings are also 8%<br />

more than in the Alternative Policy Scenario. Indirectly avoided CO 2<br />

emissions, through the reduced need to generate power, amount to<br />

0.7 Gt. Widespread use of minimum efficiency standards in a wide range of<br />

appliances and equipments could help capture this potential.<br />

Additional savings are achieved in the transport sector, mainly through<br />

improved efficiency of light-duty vehicles, increased use of biofuels and more<br />

efficient aircraft. Together, these outcomes would cut global oil use in 2030 by<br />

more than 10 mb/d, saving 1.4 Gt of CO 2<br />

. The fuel efficiency of light-duty<br />

vehicles in 2030 is 14% better than in the Alternative Policy Scenario. To<br />

achieve this, the average car sold in 2030 would need to consume 60% less fuel<br />

than the average car sold in 2005. With current technologies, only plug-in<br />

hybrids are capable of this. In addition, such cars reduce the need for oil-based<br />

fuels even more, because they use electricity from the grid. As power generation<br />

becomes less carbon-intensive, emissions are reduced by even more than energy<br />
