Energy Roadmap 2050 (20 page pdf, Communication From the Commission to the European Parliament, The Council, the European Economic and Social Committee and The Committee of the Regions, European Commission, Dec. 2011)

Image via Wikipedia
Also discussed here: Towards a competitive low-carbon energy sector (European Commission, Dec. 19, 2011
And here: EU’s “Energy Roadmap 2050” Published (Zachary Shahan, Clean Technica Dec. 27, 2011
While many countries have very modest plans to decarbonize in the short term (e.g. Canada and the US with a 17% reduction target by 2020), few countries have serious plans beyond this. The EU recently released a plan, or rather a series of scenarios, to achieve the required reduction of carbon fuels and a stable global climate by 2050 – if that is not too late for the atmosphere to recover, a question being debated between the carbon energy proponents on the one hand and serious climate researchers on the other who would see the target moved to much earlier. Whatever reductions occur, there will be significant improvements also in air pollution and the health benefits that come from that which is the prime focus of this blog, so that we follow the development of decarbonization plans such as this with much interest. Some of the implications of this roadmap are noted including the need to engage the public and the role of nuclear energy, energy efficiency, and managing energy demand.

Key Quotes:
“Committed to reducing greenhouse gas emissions to 80-95% below 1990 levels by 2050, the EU is exploring the challenges of decarbonisation”
“With electricity prices set to rise until 2030, investment is needed now in “intelligent” electricity grids and improved technologies to produce, transmit and store energy more effectively”
“In this Energy Roadmap 2050 the Commission explores the challenges posed by delivering the EU’s decarbonisation objective while at the same time ensuring security of energy supply and competitiveness”
“Vulnerable consumers are best protected from energy poverty through a full implementation by Member States of the existing EU energy legislation and use of innovative energy efficiency solutions”
“Decarbonisation scenarios
- High Energy Efficiency. …leads to a decrease in energy demand of 41% by 2050 as compared to the peaks in 2005-2006.
- Diversified supply technologies…Decarbonisation is driven by carbon pricing assuming public acceptance of both nuclear and Carbon Capture & Storage (CCS).
- High Renewable energy sources (RES)…leading to a very high share of RES in gross final energy consumption (75% in 2050) and a share of RES in electricity consumption reaching 97%.
- Delayed CCS…decarbonisation driven by carbon prices rather than technology push.
- Low nuclear. .. that no new nuclear is being built …resulting in a higher penetration of CCS (around 32% in power generation).
“Ten structural changes for energy system transformation:
- Decarbonisation is possible – and can be less costly than current policies in the long-run
- Higher capital expenditure and lower fuel costs
- Electricity plays an increasing role
- Electricity prices rise until 2030 and then decline
- Household expenditure will increase
- Energy savings throughout the system are crucial
- Renewables rise substantially
- Carbon capture and storage has to play a pivotal role in system transformation
- Nuclear energy provides an important contribution
- Decentralisation and centralised systems increasingly interact
“Transforming the energy system:
- Energy saving and managing demand: a responsibility for all
- Switching to renewable energy sources
- Gas plays a key role in the transition
- Transforming other fossil fuels
- Nuclear energy as an important contributor
- Smart technology, storage and alternative fuels

Between the Lines (Dave Gardetta, Los Angeles Magazine, Dec. 1, 2011)
The focus today, as it has been in past reviews, is the craziness involved in cities which give away free parking or set parking rates at the same low rate regardless of the demand- with a prominent example from Los Angeles compared with the more enlightened planners and traffic engineers in San Francisco which has migrated to dynamic parking prices and high tech aids to manage their traffic and parking.
The problem is not just in California, however, as you see the same thing in huge mandated parking lots and set parking fees in the downtown areas of Ottawa, Montreal and Toronto (and probably others too) – which adds to the congested misery of these air polluted, car-addicted cities.

Today’s review article is very useful overview and updated literature review of two types of pollution that are both increasing in importance and have not been as well researched as ambient air pollution as a major health impact: the burning of carbon fuels inside homes (BMFs) in developing countries and exposure to traffic related air pollution (TRAPs) near roadways. The authors conclude by listing what is known and what is not, some of which is noted below.

Chicago Cashing In on Privatized Parking; Could LA be Next? (Steven Dornfeld, City Watch, Dec. 19, 2011)
Also discussed here: CPM-Chicago Parking Meters
A key example of the value of applying the pricing concept to parking rates is described in the article reviewed today about Chicago where the investment in the new technology needed for smart meters and dynamic rates was covered by leasing the parking system to the private sector. The result is increased revenue to the city, less congestion and vehicle emissions downtown as fewer vehicles have to search for a parking space and a public that is slow to accept it- the director of parking amusingly said “Thank God we don’t have capital punishment” in Illinois”. This reminds us of the slow careful approach used in Stockholm to gain public acceptance of congestion pricing there.

Urban Traffic Calming and Health: A Literature Review ( 152 page pdf, Olivier Bellefleur & François Gagnon, National Collaborating Centre for Healthy Public Policy, Institut national de santé publique du Québec, Nov. 2011)
Today, the focus is on a report that reviews the literature on health aspects of traffic calming. Among several surprising points is that traffic calming is usually aimed at and has benefits related to reduced speed as a prime factor for injuries or fatalities from collisions. But many traffic calming techniques, such as speed humps, cause a variation in speed- a temporary slowing followed by rapid acceleration and THIS results in a doubling of vehicle emissions and lower air quality near the road. The message is to take both pollution impacts and speed impacts into consideration when implementing traffic calming.

The focus today is on the short term health impacts from coarser particles that come from traffic and roads other than through emissions- an aspect not as well studied as the impacts from fine particles. For a number of reasons, both these types of particle and the health impacts from them are highest in the winter and spring.

We know that the elderly are more vulnerable to health impacts from air pollution than other age groups but a further complication is the impact on how well these people are cared for during cycles in the economy. Today’s review is on an analysis of the link between unemployment rates and the care for the elderly in nursing homes and shows that lower unemployment generally results in fewer nursing assistants being available- at least in the USA where the study was based. In addition, because more elderly in nursing homes are women, the impact is greater for them. The broader point is that taking steps to improve air pollution during boon times would have specific health benefits for women.

Pay as you go: managing traffic impacts in a world-class city (55 page pdf, John Whitelegg, Eco-Logica Ltd, Lancaster, Dec. 2, 2011)
The report reviewed today looks back at almost a decade of experience with London’s congestion charge system and analyses the reasons for its success as well as its weaknesses. Several interesting points are made including the way that free parking at work offsets the advantages of road pricing, the process of persuasion needed to gain public support and the degree to which trucks and heavy vehicles are the source of road damage and should therefore bear higher congestion fees for road use.

The Stockholm congestion charges – lessons after 5 years (18 page pdf, Börjesson, M; Eliasson, J; Beser Hugosson, M; Brundell-Freij, K., Centre for Transport Studies, Royal Institute of Technology, Stockholm, Dec. 2011)
An excellent analysis of the social, economic and political aspects of the Stockholm congestion charges is the focus of today’s review. The report explains why the public which was against the charges initially come to support it, after they saw it worked- and traffic was permanently reduced by just under 20%. Also, the revenue generated was directed to improved public transit, already supported in Stockholm to a higher degree than in the USA or Canada with the exception of New York City, making it easier for commuters to make the switch from cars to transit. This factor, also seen in Sweden, no doubt led to the local New Yorker’s support for the proposed congestion charge scheme which was stopped in the end, not at the municipal but at the state level. Probably the most important lesson learned is the understanding and acceptance of pricing the value of a public good or service after following the approach taken by the Swedes, whether it is transportation and congestion, or by extension of the concept, to other municipal services such as waste, water or electric power.

A number of cities in the USA have seen the light and replaced expensive, ineffective, polluting freeways that divide communities with parks and tourist vistas that unite them. The article under review today summarizes the situation across the country in recent days from New jersey to San Francisco to New York to Minneapolis. Soon many more will reap the benefits and quality of life that freewayless cities such as Vancouver BC have enjoyed for years.
Bottom line “Improved traffic flow, fewer roads to maintain, nicer neighborhoods — what’s not to love?”

Proposal for a Regulation on the Sound Level of Motor Vehicles (12 gage pdf, Commission Staff Working Paper- Executive Summary of the Impact Assessment, Dec. 9, 2011)
The focus today is on a new proposal to reduce by 25% the vehicle noise which impacts the health of almost 21 million citizens of European cities. Past efforts to accomplish this have little success because of the introduction of wider noiser tires, increasing urban traffic and the slow transition from noisy to more modern quieter vehicles- despite the advent of electric vehicles which are soundless (but represent less than 5% of the cars on the road) . The situation is summed up by this quote: “After air pollution, noise is the biggest environmental health problem in Europe”.

The Hidden Toll of Traffic Jams – Scientists Increasingly Link Vehicle Exhaust With Brain-Cell Damage, Higher Rates of Autism
(Robert Lee Hotz , Wall Street Journal, Nov. 8, 2011)
Today, we return to a review of studies on the health impacts on the brain for those who breathe air near traffic. The studies indicate that the while the vehicle emissions affect everyone for periods as short as 30 minutes, impacts near traffic include the intelligence and emotional stability of children and the brain activity of seniors. There is evidence also that congestion pricing’s role in improving air quality has beneficial health impacts.

Topping the reviews today is a blog post by a lawyer who examines the potential inconsistency of environmental law, as expressed by the 1993 Ontario Environmental Bill of Rights, when applied to varying levels of air pollution across the province. Although she looked only at industrial examples (burning tires and stack emissions), the basic issue presented is whether the law could extend to differences in pollution at the neighbourhood level and, by extension in our mind, to pollution hotspots created by heavy traffic on urban public roads.

Today we look at the future of traditional North American cities with sprawling suburbs and large malls that can only be reached by car. Population trends toward an older society, the rise of carbon fuel costs and the desire for a better life style have shifted home buyers to the urban core from the suburban fringe- with huge impacts on what is left in the suburbs and the future priorities for transportation.

Torontonians Open to Congestion Charge to Fund Transportation System (8 page pdf, Angus Reid Public Opinion, Nov. 6, 2011)
The answer to the question posed today seems to be yes, judging from a poll taken recently in Toronto which interestingly also found a dislike for tolls or taxes aimed at drivers. The time to travel to work issue seems to be the main factor affecting a commuter’s decision to take their own vehicle, take transit, cycle or walk. The reduced travel time and improved air pollution levels found in London and Stockholm after several years of congestion pricing appear to be a valid argument in favour of implementing this in other large cities which suffer from congestion, especially those with small congested Central Business Districts, such as Ottawa .

It could be the solution for mitigating the part of climate change that comes from heating/cooling homes and buildings- especially in sunny, hot dry areas where cooling of buildings is so needed and where evaporative cooling works best. The other major emitter of greenhouse gases is transportation and the carbon-fuel burning vehicles which has been the focus of this blog.

The focus today is on how Annex 1 states (members of the OECD and former USSR) are preparing for impacts expected from climate change, viewed as “one of the main challenges facing public health this century”. The majority have taken no action to adapt to health vulnerabilities. Flooding, general extremes, and air quality were recognized as the main threats and extreme cold as the least. Overlooked by many is the vulnerability of their elderly- whose numbers will double over the next few decades at the same time as periods of extreme heat and high pollution increase as a result of climate change.

The implication for an additional health impacts of climate change is clear – unless year-round precautions are taken by hospitals during hot spells and, in general, as climate warming progresses, we will see more infections. It is worth noting that the spread of insect-borne diseases such as West Nile Virus is also a growing threat in countries such as Canada where winter cold has lessened and allowed insects and birds to carry the disease further north. Also, the convergence of more urbanization, greater use of emission producing vehicles and the large role these vehicles play in causing climate change points to the other major factor and potential solution in reducing these health threats in cities.

Planning for Cars in Cities – Planners, Engineers, and Freeways in the 20th Century (18 page pdf, Jeffrey R. Brown, Eric A. Morris, and Brian D. Taylor, Journal of the American Planning Association, Vol. 75, No. 2, Spring 2009)
Today’s review article describes the development of major roads in cities, how and why they evolved from the original concepts for urban planning 100 years ago with examples from Los Angeles, Chicago and Boston, through the introduction of the national interstate highway system and ending with the state of roads in most cities today- which seem deem as “traffic sewers” but others call urban freeways.

Traffic Congestion and Accidents(26 page pdf, Andrea Schrage, University of Regensburg Working Papers in Business, Economics and Management Information Systems, Nov.9, 2006)

Image via Wikipedia
The report reviewed today looks at the calculation of optimum congestion charging with the cost of accidents included in that calculation. To do that the author considered the timing of the accident (earlier or later during the daily rush hour) and how an accident could be factored into the modelling needed to estimate an optimum pricing.

Contrasts in Oxidative Potential and Other PM Characteristics Collected Near Major Streets and Background Locations (32 page pdf, Hanna Boogaard, Nicole A.H. Janssen, Paul H. Fischer, Gerard P.A. Kos, Ernie P. Weijers, Flemming R. Cassee, Saskia C. van der Zee, Jeroen J. de Hartog, Bert Brunekreef, Gerard Hoek, Environ Health Perspect, Oct. 20, 2011)
Today’s review article looks at how particulates near heavy traffic on major streets generates hydroxyl radicals and how this in turn may be a better measure of health impacts than simply monitoring PM 2.5 or PM 10. The results indicate the oxidative potential near heavy traffic was 4 to 6 times greater than in suburban locations.

Effects of Urban Surfaces and White Roofs on Global and Regional Climate (Abstract, Mark Z. Jacobson, John E. Ten Hoeve, Journal of Climate, Sep. 12, 2011)
From the meteorological modelling community comes an article today examines the significance of urban heat islands as a factor in climate change- turns out that it is not. It also tests the hypothesis that painting roofs white would reduce the amount of warming of the atmosphere and thereby delay climate change. The model shows that the converse is true because there would be less heating at the surface resulting in less convection and less cloud which globally would allow more sunlight to warm the atmosphere.

The Fundamental Law of Road Congestion: Evidence from US Cities ( Abstract, Gilles Duranton and Matthew A. Turner, American Economic Review, Oct. 2011)
Yet another paper is reviewed today from an economic viewpoint, concluding that congestion pricing is the only way to reduce congestion. Not even more public transit offers relief. Where pricing has been used, the results in terms of revenue, pollution reduction and less congestion are so evident that public acceptance is clear.

Congestion Charging in The Greater Copenhagen Area (18 page pdf, The Municipal Forum, June 2008)
Copenhagen appears to be on the road to implement congestion charges (or road pricing beyond the city) after the publication of a report (reviewed below) by their Municipal Forum which attempts to build on the successes of London and Stockholm. An interesting aspect is the amount of consideration given to uses of the revenue generated with specific examples to benefit cyclists, public transit and traffic management.

The political calculus of congestion pricing: credible commitments, hostages and opportunities for implementation (33 page pdf, David A. King, Transport Futures Mobility Pricing Conference, Feb, 2011)
The reason why congestion charging is seen as political suicide is the focus for today’s post based on a survey of municipal politicians and urban planners in Los Angeles. Among the reasons for objections is a feeling of mistrust between the municipality and state on sharing revenue as well as the feeling that congestion on city streets comes mainly from freeways that cross cities and not from conditions on the streets themselves, and notably the lack of confidence on where congestion charging revenue would be spent. That confidence can be built by emulating London’s example of improving public transit before implementing tolls.

Health Impacts of the Built Environment: Within-urban Variability in Physical Inactivity, Air Pollution, and Ischemic Heart Disease Mortality (34 page pdf, Steve Hankey, Julian D. Marshall, Michael Brauer, Environ Health Perspect, Oct. 17, 2011)
Today we review some research into the link between physical inactivity, air pollution and health impact at the inter-urban scale. The results indicate that while inactivity has the greatest single health impact, this impact can be increased in densely inner city neighbourhoods with higherer levels of PM pollution.

Heavy vehicle traffic is related to wheeze among schoolchildren: a population-based study in an area with low traffic flows (31 page pdf, Martin Andersson, Lars Modig, Linnea Hedman, Bertil Forsberg and Eva Ronmark, Environmental Health, Oct. 13, 2011)
Today the focus is on a study of the health threat posed by emissions from traffic within 200 m of schoolchildren in a cold climate. The results indicate that these emissions pose a threat even when the traffic is not heavy and this implies an even greater link between traffic and pollution generally.

The European Environment – State and Outlook 2010 – Air Pollution (46 page pdf, European Environment Agency, 2010)
The report reviewed today is an overview of the progress (or lack of progress) being made or forecast in Europe to meet EU objectives. Clearly, the main challenge has to do with particulate matter and nitrogen dioxide and managing the main sources: hydro plants and transportation. One striking observation is that as electric vehicles are introduced to reduce urban emissions, rural areas may suffer as the sites of expanded electric generating utilities.

Honing the Methods: Assessing Population Exposures to Motor Vehicle Exhaust (28 page pdf, Chris Van Atten,Michael Brauer,Tami Funk, Nicolas L. Gilbert,Lisa Graham,Debra Kaden,Paul J. Miller,Leonora Rojas Bracho,Amanda Wheeler,and Ronald H. White, Commission for Environmental Cooperation, Nov, 2004)
Today’s article under review is the result of a major international workshop convened in Montreal Canada in 2003 to consider recommendations for assessing exposure to vehicle emissions and the resulting health impacts, especially to young children and the elderly. It points out one application of a California law forbidding school sites within 500 ft of traffic. A caution is expressed about the widespread urges of urban planners towards intensification which may present new health hazards to the denser populations in the urban core.
