• Principal Investigator: Dr. Arne Winguth/ UTA; 2015

• Performed trend analyses of historical and projected climate data for DFW Metropolitan Area

• Developed an Asset Inventory of existing and future transportation infrastructure in Dallas & Tarrant Counties (roads, passenger rail and aviation)

• Assessed vulnerability from “extreme temperature and precipitation” impacts to primary transportation systems

Fourth National Climate Assessment, Vol II — Impacts, Risks, and Adaptation in the United States

• Food, Energy, and Water Resources - Quality of life in the region will be compromised as increasing population, the migration of individuals from rural to urban locations, and a changing climate redistribute demand at the intersection of food consumption, energy production, and water resources.

• Infrastructure - The built environment is vulnerable to increasing temperature, extreme precipitation, and continued sea level rise, particularly as infrastructure ages and populations shift to urban centers.

• Ecosystems and Ecosystem Services - Terrestrial and aquatic ecosystems are being directly and indirectly altered by climate change.

• Human Health - Health threats, including heat illness and diseases transmitted through food, water, and insects, will increase as temperature rises.

Lack of National and State Action

• Federal executive branch favors coal and other fossil fuels over renewable energy

• The Governors’ November 2018 Rebuild Texas Report recommended eight measures to “future proof” the state, but did not address climate change or mitigation

13

• Cities consume 2/3 of the energy world wide

• Cities generate 70% of the world CO2 emissions

• Urban population is nine times larger today than 100 years ago and increasing

• Actions taken at the city level can have a major impact

• City leaders are more directly accountable to the public than state or federal officials.

Opportunities For Cities to Lead the Way

Climate change should not be a partisan issue. I disagree with any decision that undermines our nation’s leadership role in the fight to mitigate the effects of climate change. Dallas is a leader in emissions reduction efforts, and we have had significant success in reducing our carbon footprint. I am asking our staff to continue to develop and maintain programs that improve regional air quality, reduce carbon emissions and otherwise address climate change. This is a common-sense approach that is good for our citizens, our businesses and our planet.

Monitor & Verify Results

A Standard Protocol Is Required For Consistent Results

20

Any city that uses the ICLEI protocol can compare GHG emissions directly to other

cities

ICLEI offers the “Clear Path” online tool to assist with the inventory

The International Council for Local Environmental Initiatives (ICLEI) is one

commonly accepted protocol

other land use

Next Steps

34

• Use GHG emissions inventory to develop Comprehensive Environmental & Climate Action Plan (CECAP)• Actionable steps and goals building

on the Resilient Dallas plan adopted by Council on August 8, 2018

• Use unified approach to environmental planning to better serve our community and strategic priorities

• Continue to encourage City emission reduction initiatives and conduct emissions monitoring

• Revisit GHG emissions inventory using 2020 data

35

Scope: Comprehensive Environmental & Climate Action Plan

Project Scope includes:• Compile & review City

plans/data • Benchmark best management

practices & identify Dallas options

• Develop internal/external City working groups

• Robust public outreach & engagement

• Perform modelling to assess effectiveness

• Develop & vet Dallas plan
