SIMAP integrates two tools

•Developed in 2001 at UNH•Excel and web version•Used by thousands of

institutions

•Developed in 2009 at UVA•Excel-based•Used by 20 institutions•Completed pilot testing

Why a new tool?

1) Broader picture of environmental impacts

2) Integrate with other reporting platforms

3) Single tracking tool

How did we get here?Nitrogen

Challenge: Optimize the use of nitrogen,

while minimizing the negative impacts

Necessary for lifeSynthetic fertilizer provides unlimited N supply for food

Negative impacts to environmental & human health

Benefits Drawbacks

Why do we care about nitrogen?

A nitrogen footprint is the amount of reactive nitrogen released to the environment as a result of an entity’sresource consumption

Consistent trends across C & N footprints

Carbon and nitrogen footprint

projections and scenarios

C N

• Estimate effects of management strategies on current or projected footprint:– Changes in emissions

– Cost of scenarios

What are projections and scenarios?

Projections Solutions/scenarios/projects

• Estimate future emissions based on:– Population growth– Planned construction– More!

Both are important for accurate and informed goal setting!

• Users entered detailed project* data in CCC– No “standard scenarios”

• Metrics to view results in the CCC:– Impact on C footprint

– Life-cycle cost of project

– Payback time of the project

– Net present value (life-cycle cost/savings per ton of C)

What methods have been used?

Projections Solutions/scenarios/projects

• Methods for projecting in the CCC:– Linear– Normalized by students– Normalized by square feet– Custom trends– Variable trends

Questions about projections and scenarios?

Part 2: Integrated planning strategies

Alley LeachUniversity of New Hampshire

Sustainability Institute

Questions for proposing C+N goal

1. What other sustainability goals are in place or planned?

2. At what level should the goal be approved (e.g., governing

body, university)?

3. How should the goal be framed (e.g., overall, scopes)?

4. What should the goal year be?

5. What should the % reduction goal be?

2. At what level should the goal be approved?

1. Research exercise: Internal stand-alone N footprint calculations and/or goal

2. Grassroots action: No goal, but working with stakeholders to push reduction strategies

3. N benefits: No goal, but N benefits mentioned in other plans

4. Goal based on existing plans

5. New goal approved by governing body Higher commitment

Lower commitment

NO G

OAL

GOAL

3. How should the goal be framed?

• Overall goal• A single reduction goal for the overall N footprint

• Per capita/normalized goal• Reduction goal(s) normalized to campus users

• Scope goals• Separate reduction goals for scope 1+2 (local) and scope 3 (not local)

• Sector goals• Separate goals for energy, transit, food, etc.

Other questions to consider:

4. What should the baseline year and goal year be?

5. What should the % reduction goal be?

Take-aways for UVA’s Nitrogen Action Plan

1. Current action plans strategies will allow UVA to reach 25%

reduction goal.

2. Collaboration with multiple sectors at the university (dining, facilities,

health system, etc.) will reduce N footprint and meet other goals!

A climate resilience plan at the University of New Hampshire

Jennifer AndrewsUniversity of New Hampshire

Sustainability Institute

Framing Resilience: “Five Capitals” Model

Findings: Priority Opportunities• Use improved understanding of needs to improve social capital/systems to drive change in

other capitals, primarily by working to break down silos and ensure collaborative, inclusive, transparent and effective processes

• Better communication and outreach• Continue/enhance student engagement• Add community representatives to Task Forces• Water conservation – demand/summer, $• Promote active transportation• Update WildCAP to meet/exceed GHG reduction goals • Land conservation policies in light of development pressure• Updated and implement Landscape Master Plan• Accelerate sustainable food initiatives• Provide more interpersonal resilience skills training for students, staff, faculty• Research: groundwater mapping• Research: supply chains• Focus on indicator data collection

The Five Capitals:Connected to Every Aspect of Sustainability

Physical • Energy and GHG planning• Buildings, deferred maintenance, and codes and

zoning;• Greening of fleets, streets (i.e. storm water) and

TDM; • Supply chains for food, water, waste disposal

Natural/Ecological• Landscape master plan update • Nitrogen footprint reduction • Land policy committee: zoning, land use planning

Human• “Healthy UNH”—including Menus of Change• Learning outcomes• Research and engaged scholarship• “Campus climate”• Sustainable food systems• Inclusion and diversity

Social • Coordination and planning• Social justice and racial equity

Financial • Move to life-cycle cost accounting in planning• Housing affordability• Living wages• Staffing and employment• Corporate social responsibility, social innovation• Sustainable investment

SummaryProjections and scenarios Goal setting

• Important for informed and accurate goal setting

• Excel templates available now

• Beta testing in early 2019

• Lots of options for integrated carbon and nitrogen goals

• Integrated goal setting is win-win for sustainability initiatives
