India’s Vehicle Population Is Growing Rapidly As Is Oil Consumption & CO2 Emissions
Fuel Economy Labeling & Standards Are Coming To India Many Technologies Available Improved Transmissions GDI Hybrids Diesels
But CO2 Is Not The Whole Story Particles Greenhouse gases Black carbon (R&C, 2008) CH4 CO2 Halo-carbons Black carbon (IPCC, 2007) Orange: Dirty Snow Effect Sulfates Nitrates Organic carbon Dust
Co-emissions of organic carbon and/or other particles may partially offset BC warming Direct BC warming is large at the global (and regional) scale BC deposition on snow has a strong warming effect BC has a Significant Impact on Global Warming Sources: IPCC AR4 WG1 2007 for all except Ramanathan & Carmichael 2008 BC bar
