22 The Choice

23 Transit GHG Emissions Typology APTA Climate Change Standards Working Group

24 Total: 2.3 million metric tons Non-Revenue Fleet -Traction Electricity-Traction Electricity - Non-traction Transit Effect Multiplier = 8.24 For every unit of GHG that the MTA emits Heating - Non-traction It helps avoid 8.24 units In the net it helps avoid about 17million metric tonnes Currently un-recognized and un-compensated Revenue Fleet Fuel -Traction MTA GHG Emissions, 2008

25 Energy/ Carbon Facilities Smart Growth/TOD Materials Flow Water Climate Management Adaptation Greening the MTA

27 80% Renewable Energy by 2050 Revenue from carbon avoidance Reduce energy use and GHG emissions on a per passenger-mile basis by 25% by 2019 Energy / Carbon

28 Build all new projects and major renovations to LEED Silver standard Recommission existing buildings to meet LEED Silver standard Create LEED-based MTA Green Guidelines for other building types Facilities

29 Energy Saving through Alignment Design: Humped Tracks Track Alignment

30 Vegetated, green roofs (MNR Harmond Yard, MTA Bus Far Rockaway Depot, B&T Queens Midtown Tunnel) and white roofs (LIRR Hillside) Green Roofs and Walls

31 Adopt Life Cycle Accounting Quantify and track materials flow Green the procurement and budget process Flex market power in purchasing Materials Flow

42 Conclusions As societies develop/industrialize, their energy needs rise. Transportation emerges as a major consumer of energy. Automobile-based paradigm with corollary suburban sprawl is wasteful and unsustainable It negates the good effects of green building methods and technologies Sustainable growth has to embrace density and support public transportation Designing the right carbonconstrained system can make this happen
