Reference Scenario<br />

Alternative Policy Scenario<br />

<strong>Energy</strong>-Related CO 2<br />

Emissions<br />

The policies and measures analysed in the Alternative Policy Scenario significantly<br />

curb the growth of India's energy-related CO 2<br />

emissions. Lower overall energy<br />

consumption, combined with a larger share of less carbon-intensive fuels in the<br />

primary energy mix, yields savings of 27% in emissions by 2030, compared with<br />

the Reference Scenario. The savings in emissions are already marked by 2015,<br />

when they reach 11%. Nevertheless, emissions continue to rise, reaching 1.6 Gt<br />

in 2015 and 2.4 Gt in 2030, compared with 1.1 Gt in 2005. Per-capita emissions,<br />

which are 2.3 tonnes in 2030 in the Reference Scenario, fall to 1.7 tonnes.<br />

The largest single contribution to emission savings comes from greater energy<br />

efficiency. Overall, energy-efficiency improvements on both the demand and<br />

supply sides and fuel-switching in power generation account for 72% of the<br />

total savings (Figure 18.4). Renewable energy, notably hydropower in the<br />

power sector and biofuels in transport, contributes 24% to the overall<br />

reduction in emissions. Nuclear power contributes 5%.<br />

The biggest reductions are in the power sector, where emissions are lower by a<br />

third, as a result of policies to encourage low-carbon generation and to use coal<br />

more efficiently, and because demand for electricity is lower. The CO 2<br />

intensity of<br />

electricity generation declines even further, compared with the Reference Scenario<br />

(Figure 18.5). At 550 g/kWh, it is 18% lower in 2030 and 42% lower than in<br />

2005. Transport emissions fall by 22%, reflecting greater vehicle efficiency and<br />

greater use of alternative fuels. Emissions in the residential, services and agriculture<br />

sectors are 13% lower in 2030, compared with the Reference Scenario.<br />
