MAIN ISSUES Key sources Atmospheric chemistry and interactions Direct and indirect health effects Policies Solutions – Technical and non-technical Co-benefits or unanticipated outcomes NERAM V October 17 2006
Knowledge Gaps: AQ & CC • Atmospheric science: highly complex, uncertainties, forecasts/scenarios • Scale: hemispheric, transboundary, local – [GHG] truly global • Temporal differences between pollutants and response times • Sources: Energy/Electricity, Transportation, Agriculture, LIEs, SMEs • Health effects: Climate change on air quality; synergistic impacts of heat stress; other health effects (e.g. WNV) • Technological and non-tech solutions: similar challenges but significant differences • Policies: silos; counteractive; synergistic NERAM V October 17 2006
So How Do We Move Forward? Need to Move Past the Four Stages of Denial • Deny there is a problem • Deny you are a source/part of the problem • Deny that there is a technological solution • Deny that the technological solution is economically feasible or affordable NERAM V October 17 2006
Framework To Evaluate AQ and Climate Change Strategies • Degree of scientific certainty about the problem and health effects • Knowledge of main emission sources? • Agreement on solutions and expected outcomes? • Which are economically feasible and politically acceptable? • Direct and indirect impacts of solutions and how are these being contested in the political arena? (e.g. nuclear option) NERAM V October 17 2006
Key Linkages: Chapter 5 • Chemical/atmospheric interactions • Actions that directly reduce GHGs and other air pollutants • Actions that indirectly reduce energy use and emissions • Actions that are both mitigation and adaptation – measures which reduce emissions and enhance adaptive capacity NERAM V October 17 2006
Climate Change – Air Quality: IPCC • Co-benefits: big picture is challenging • Substantial health benefits from CO2 mitigation strategies via improved AQ • Need for integration: options for harvesting synergies • Coal AQ technologies lock in coal, can undermine alternatives (e.g. renewables, efficiency) • Agriculture: ammonia emissions – nitrous oxide and methane • Methane as a precursor to tropospheric ozone • Tropospheric ozone a potent GHG • Biofuels and black carbon • Diesel: CO2 and PM2.5 NERAM V October 17 2006
Air Quality – Climate Change Q. What is the perspective from AQ experts? A. ?????????????????????????????? Our Challenge Tomorrow: • Guidance Document • Recommendations from NERAM Colloquium V NERAM V October 17 2006
Engineered interventions to avoid • Aerosols help reduce 25% regional effects of climate change (cooling effect) • Produce more locally based sulphates • NOx scavenges O3: • Encourage more car use to reduce smog These types of decisions best left to a higher authority! NERAM V October 17 2006
Actions to Consider • Actions that are ethical, consider environmental justice and lead to a clear environmental and health gain • Need to address more than just the symptoms, but also the underlying causes • Should focus on sources and solutions that produce the biggest benefits NERAM V October 17 2006
Does addressing air quality issues through actions that reduce GHG emissions produce a broader suite of benefits and clear outcomes, than addressing climate change by reducing emissions of other air pollutants? 2006 AIR QUALITY CLIMATE CHANGE NERAM V October 17 2006

UN Framework Convention on Climate Change • Article 2 • “ … stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. Dangerous – how much change? Stabilization – at what level? The EU has chosen 2C global warming as the “dangerous” level – only 1.3C more warming. NERAM V October 17 2006
The abundance, atmospheric lifetime, and Global Warming Potential of GHGs vary considerably Carbon Dioxide Methane Nitrous Oxide Halo Carbons NERAM V October 17 2006
Kyoto and the Inevitability of Climate Change “The overwhelming majority of scientific experts, whilst recognizing that scientific uncertainties exist, nonetheless believe that human-induced climate change is inevitable. . The question is not whether climate will change... but rather how much... how fast, and where” Robert Watson, Chair of IPCC to CoP6 Delegates, The Hague, November 2000 Adaptation is necessary More mitigation is needed Stabilization: 40 Kyotos Needed NERAM V October 17 2006
Urgency of Situation:Window is 0-15 years EU: 25% reduction by 2020; Global reductions of 60 to 80% by 2050 NERAM V October 17 2006

OMA Estimates How will climate change affect air quality? NERAM V October 17 2006
Heat waves in Canadian cities will become more frequent Number of hot days above 30C Background ambient levels of O3 could increase by 40 ppm Emission increase by 20% by 2050 and 32% by 2080. The annual total number of poor O3 days would increase 4-11 and 10-20 respectively. Air pollution mortality will increase by 20-25% and 30-40% by 2050 and 2080 Number of heat-related deaths will double and triple NERAM V October 17 2006
Where do we need to make reductions? NERAM V October 17 2006
Transportation Example • Further reduce the emissions of the current transportation system using new and improved technologies • Get more people out of their cars and onto public transit • Change development patterns to slow urban sprawl and to encourage denser development NERAM V October 17 2006
Accomplishments? • Low sulphur fuels • Improved technologies • Inspection and maintenance • Gas tax allocation to support transit • Infrastructure renewal • Tax credits for transit passes • Ethanol/biodiesel • CAFE standards • Mercury switch-out • Vehicle retirement NERAM V October 17 2006

Canadian Attitudes Towards the Environment • 10% identified environment as the most important issue facing Canada today • 23% identified air pollution as the most important environmental issue • 4% climate change/global warming • 91% agreed that we have a responsibility to the next generation to do all we can to correct climate change • 77% agreed that Canada must act now on climate change because the risk of waiting is too high NERAM V October 17 2006
