2 Agenda 1. Tulane and Climate Action Planning 2. Linking CAP- Activity to Demand Side Energy Management 3. Current and Past Efforts 4. Demand Side Use 5. Ideation

3 Climate Action Plan: Introduction What is a Climate Action Plan (CAP)? A set of strategies to reduce an entity s greenhouse gas emissions Focus on buildings and transportation two biggest generators by category of activity Who develops them? Government federal, state and municipal Higher education American College and University Presidents Climate Commitment (680 entities) International Sustainable Campus Network Charter (53 entities) Other and similar initiatives, as with AASHE STARS Industry

4 Climate Action Plan: GHG Scope Emissions as Key Metric Source: A New Perspective for Labeling the Carbon Footprint Against Climate Change (Villar, Hidalgo, Penela, Mejide)

5 Tulane s Early GHG Emissions Reduction Activities Prior to formalizing its commitment to GHG emissions reduction, Tulane engaged in activity towards that end: Energy system improvements Design and construction energy efficiency goals/standards Uptown plant water treatment and campus boiler replacement Energy Star purchasing policy Technology Services measures Transportation enhancements Education Research Source: Tulane 2011 CAP

6 Tulane and the Impetus to Create a CAP In 2008, Tulane pledged to the American College and University Presidents Climate Commitment: Recognizing the scientific consensus about global warming Recognizing the need to reduce global GHG emissions by 80% by mid-century to avert worst impacts of global warming Committing that university will lead by example in minimizing emissions and must provide knowledge to students of means to achieve climate neutrality Ascribing to the belief that this act will stabilize and reduce long-term energy costs, attract students and faculty, attract new sources of funding, increase support for the pledging institution Soon after, Tulane started on its Climate Action Plan. Completed in 2011, it has not been formally adopted by the university.

7 Tulane Draft CAP Strategies for Emissions Reduction Draft CAP Goal: 7% GHG reduction from 2007 level by To be accomplished by: Enhancing energy management energy engineer, meters and meter data use, retrocommission major buildings Improving computer power management Motivating more bicycle use Enhancing shuttle and transportation programs Initiating first renewable energy project Establishing best options for replacing 5% of campus electricity use through renewable energy Integrate energy efficiency priorities into building renovation plans Draft CAP Illustration of its Planned GHG Reductions Draft CAP Goal: 15% reduction from 2007 level by 2020 To be accomplished by: Scaling-up renewable energy use Building energy efficiency renovation and retrofit Providing the equivalent to 5% of campus electricity use Source: Tulane 2011 CAP

8 Strategies for 2015 Emissions Reduction Target This is an established way of presenting GHG emissions reductions investments. It describes the costs and carbon reduction contributions of each element of a portfolio. Source: Tulane 2011 CAP

9 Draft CAP on the Question of Project Financing Tulane Draft CAP recommends a portfolio of reductions investments It suggests potential funding sources: Operating funds University donors Student fee or Reserve Fund Renewables through third party funding Energy efficiency revolving fund Performance contract (Johnson Controls) Source: Tulane 2011 CAP

10 Tulane GHG Emissions: 2007 to 2012 Annual GHG emission inventories show 2012 emissions to be almost identical to 2007 emissions, even with growth in campus square footage Source: Tulane University 2011 & 2012 Greenhouse Emissions Inventory and Tulane 2011 CAP

11 Draft CAP Goals and Actual Emission Change Over Time 15% Tulane University GHG Emissions: (Percent Change: Actual and Goals) 10% 5% Building SF Building Emissions Scope 1 Emissions Scope 2 Emissions 0% 2012 Total Emissions 5% 10% 2015 CAP Goal 15% Scope 3 Emissions This shows relative rate of growth of key emission metrics and compares them to emissions goals established in the Draft CAP CAP Goal Data from Tulane University 2011 & 2012 Greenhouse Emissions Inventory

12 What to Expect in the Tulane Climate Action Plan Update Engagement of Uptown and Downtown Campus communities A revisiting of the 2011 Draft CAP goals, including consideration of expanding on phased implementation Articulation and exploration of options, selecting a preferred route for reaching CAP goals Detail developed for preferred route, including economic, GHG emissions mitigation and other considerations Support to the university in updating its survey of commuting/transportation patterns Completion in 2014 Project Phases
