Who Is Legally Responsible for Climate Change Impacts (and avoiding them)?

International Climate Change Liability: A Myth or a Reality? (Jennifer Kilinski, 42 page pdf, J. of Transnational Law & Policy, Spring 2009)

Also discussed here: Office of the Auditor General 2012 Annual Report (City of Ottawa, Nov. 28, 2013)

And here: The Alaskan village set to disappear under water in a decade (Stephen Sackur, HardTalk, BBC News Magazine, Jul. 29, 2013)

And here: The Moral and Criminal Case Against Canada's Climate Negligence (William Rees, Dec. 7, 2013)

Today we review the liability of companies which emit greenhouse gases for losses caused by anthropogenic climate change. Several suits have been raised in the last 5 years by plaintiffs that have suffered significant impacts against the main emitters of carbon pollution which in the USA is the electrical generation industry which is responsible for 25% of that nation’s emissions. 

While these suits concern flooding from sea level rise of Arctic islands, such as Kivalina, Alaska, the Auditor General for the City of Ottawa found that “Lack of a systematic and comprehensive climate change adaptation plan may result in impairment to municipal infrastructure and services due to extreme weather resulting from climate change. This could then result in potential legal action due to sustained property damage”. This liability was linked to the provincial Emergency Management and Civil Protection Act requires an emergency preparedness plan be in place. 

Taking this thinking a step further, most of the world’s greenhouse gas emissions originate in cities and one of the principal GHG emitters is the transportation sector and private vehicles n particular which are owned and driven by around 70% of the city’s population. Those most affected by air pollution from these vehicles are too young or too old to drive. Just as the Inuit on a small Alaskan island are among the lowest emitters of GHGs and suffer the most from climate change, the same logic applies to the young and elderly in cities who conceivably could launch a valid class action against those responsible for vehicle emissions for both health impacts, accentuated by climate change, and for damage to property and infrastructure as the Auditor General found. The Court found in the Kivalina case that regulation of greenhouse gases was a political rather than a legal issue and one would look for accountability at that level. 

 However, the failure of the City of Ottawa to prepare a plan of action to protect and adapt to climate change appears to provide a potential legal recourse for those suffering losses, whether they be structural or health. In addition, cities have a dominant role and mandate in regulating traffic, congestion and roads, as well as the ability to price use of these, which in turn gives cities the ability to regulate greenhouse gas emissions and the liability that goes with this responsibility. How long will it take those who are impacted to sue the city and vehicle owners for damages?


Key Quotes:
“Human activities caused global GHG emissions to increase more than 70 percent between 1970 and 2004 alone.. The global sea level rose at an average rate of 1.8 mm a year before 1993 and 3.1 mm a year since then”

“the ideal plaintiffs are those individuals or group of individuals who contribute the least but are harmed the most, who are discrete and identifiable, and who can demonstrate significant and specialized harms readily linked to greenhouse gas emissions.”

“the Inupiat Eskimo Village of Kivalina, Alaska filed suit against twenty-four of the world’s largest oil and energy companies,157 alleging that they caused the global warming responsible for significant harms to Kivalina…. The suit was dismissed by the United States district court on September 30, 2009, on the grounds that regulating greenhouse emissions was a political rather than a legal issue and one that needed to be resolved by Congress and the Administration rather than by courts.”

“for a climate change suit, plaintiffs need to demonstrate that the emissions caused by the named defendants are such that they interfere with the public health, safety, peace, convenience, or comfort, and that defendants knew or had reason to know of the effects upon the public right.”

 “in Connecticut v. American Electric Power Co.,141 Connecticut, seven other states, the City of New York, and several environmental groups sued a group of electric utilities under federal public nuisance common law, asking them to abate the global warming nuisance… the defendants were the five largest emitters of carbon dioxide in the United States..”

“- The Air Quality and Climate Change Management Plan[City of Ottawa, 2004]..outlined a risk assessment and mitigation plan to be undertaken in phase II (scheduled to occur in 2005-06), but no progress was made in this area….Lack of an assessment of the impact of climate change to waste water infrastructure will exacerbate risks noted in that area as well..The level of control over adapting to climate change is not well controlled as no ownership has been identified and attention to adaptation requirements is sporadic..”

"Everyone is criminally negligent who (a) in doing anything, or (b) in omitting to do anything that it is his duty to do, shows wanton or reckless disregard for the lives or safety of other persons” [Canadian Criminal Code (Section 219))

What Improvements Are Needed to Regulate Urban Air Quality?


Today we review a report from the European Commission on a pilot project carried out in 12 cities to assess and make recommendations on the deficiencies and next steps to address the threats to human health from urban air pollution. Despite (or perhaps because of) the enactment of more restrictive regulations than seen elsewhere in the world, several pollutants remain above thresholds (O3, PM2.5 and NO2 in particular), gaps remain in emission inventories and networks and the principal solution lies in regulating traffic. Recommendations include putting a much greater focus on data, distributing information to the public and carrying out regular health impact assessments.

Key Quotes:

“Eight cities originally took part in the pilot: Berlin, Dublin, Madrid, Malmö, Milan, Ploiesti, Prague, and Vienna. Four more cities subsequently joined at the end of 2012: Antwerp, Paris, Plovdiv, and Vilnius.”

Current Deficiencies:
  • emission inventories…”Cities have problems taking into account all sources of pollution, due to the difficulty in finding available data, or because of the difficulty in appropriately quantifying different sources.”
  • modeling.. “Because air quality models make use of emission inventories, often the shortcomings of these inventories carry over to the modelling activities”
  • monitoring networks…”criterion for the macro‑scale siting of ozone stations (their distribution between urban and suburban locations) has not always been met”
  • management practices…”In most of the cities, and in agreement with the main pollutant sources identified, more than the 50 % of the implemented measures are traffic related”
  • public information…”the cities underuse mass media, social media websites, and new technologies like smartphone applications….cities lacked feedback on the interest of their citizens in air quality issues.”
“Next steps:
  • focus on data. The Air Implementation Pilot has shown the importance of comparable, timely information on air quality, and the role of this information in improving implementation….
  • streamline further its own information systems to support the implementation of EU air policy….
  • deliver regular assessments of European air pollution, its impacts, and the effectiveness of air quality measures…”

What Are the Links between Premature Deaths, Air Pollution and Climate Change on a Global Scale?

Global premature mortality due to anthropogenic outdoor air pollution and the contribution of past climate change(12 page pdf, Raquel A Silva, J Jason West, Yuqiang Zhang, Susan C Anenberg, Jean-Franc¸ois Lamarque, Drew T Shindell, William J Collins, Stig Dalsoren, Greg Faluvegi, Gerd Folberth, Larry W Horowitz, Tatsuya Nagashima, Vaishali Naik, Steven Rumbold, Ragnhild Skeie, Kengo Sudo, Toshihiko Takemura, Daniel Bergmann, Philip Cameron-Smith, Irene Cionni, Ruth M Doherty, Veronika Eyring16, Beatrice Josse17, I A MacKenzie15, David Plummer, Mattia Righi, David S Stevenson, Sarah Strode, Sophie Szopa and Guang Zeng, Environmental Research Letters, Jul. 11, 2013)

And here: Air Pollution Responsible for More Than 2 Million Deaths Worldwide Each Year, Experts Estimate(Science Daily, Jul. 12, 2013)
 
Today we review a new estimate of the global burden of premature deaths due to ozone and particulate matter 2.5 which total 2.1 million deaths each year due to PM 2.5 and 470,000 due to ozone. Using a different set of assumptions than used previously, the role of air pollution-related climate change from 1850 to present is seen to be smaller than expected with only 3,700 deaths due to this – not to state that future climate change would be greater.

Key Quotes:
"Our estimates make outdoor air pollution among the most important environmental risk factors for health. Many of these deaths are estimated to occur in East Asia and South Asia, where population is high and air pollution is severe."

“around 470,000 people die each year because of human-caused increases in ozone. It also estimates that around 2.1 million deaths are caused each year by human-caused increases in fine particulate matter (PM2.5)”

“a changing climate results in 1500 deaths due to ozone and 2200 deaths related to PM2.5 each year.”

“Very few studies have attempted to estimate the effects of past climate change on air quality and health. We found that the effects of past climate change are likely to be a very small component of the overall effect of air pollution,"

What’s Wrong with Estimating Traffic Congestion Using GPS Statistics?

The problems with measuring traffic congestion (Felix Salmon, Reuters, Oct. 17, 2012  

Also discussed here: The problems of measuring traffic congestion (Road Pricing, May 15, 2013)

And here: TomTom Congestion Index(Tom Tom, Mar. 22, 2013) And here: TomTom North American Congestion Index(68 page pdf, Tom Tom, Mar. 22, 2013)

Today we review an article that criticizes the effort to estimate congestion in 120 cities world-wide by a major GPS producer, TomTom. The author, Felix Salmon, points out several issues that reduce confidence in the city by city congestion indices: the lack of an independent measure of congestion that would calibrate the GPS-based estimates, the assumption that the speeds of vehicles using the GPS represent the speeds of the average or all vehicles on the road at the time and the weight given to various road segments being measured. The bottom line is that the efforts to reduce congestion by road pricing require a sound way of measuring congestion in order to recognize success or failure of the pricing method used in a given city. While TomTom should be congratulated for its efforts so far, it seems that a second or third objective and consistent way of measuring congestion is needed.

 tom tom congestion  

Key Quotes:

 “A congestion index like this one serves two purposes.
  • to compare a city to itself, over time: is congestion getting better, or is it getting worse?
  • to compare cities to each other: is congestion worse in Washington than it is in Boston?”
“TomTom only looks at road segments where they have a large sample size of traffic speeds — big enough to give “statistically sound results.. The next step is weighting the different road segments, giving most weight to the most-travelled bits of road…But if you want to work out where a city’s drivers drive the most and drive the least, then you need a much larger and much more representative sample….TomTom is always going to get data weighted heavily towards people who don’t know where they’re going — out-of-towners, or drivers headed to unfamiliar destinations.”

“measuring congestion on a percentage basis tends to make smaller, denser cities seem worse than they actually are”

 “the whole idea of congestion charging has a very big problem at its core. There’s no point in implementing a congestion charge unless you think it’s going to do some good — unless, that is, you think that it’s going to decrease congestion”

What Do You Need to Know to Build a Net-Zero Energy Home?

Strategies to Achieve Net-Zero Energy Homes: A Framework for Future Guidelines Workshop Summary Report(51 page pdf, Nancy A. McNabb, Engineering Laboratory, National Institute of Standards and Technology, April 2013)

Also discussed here: Strategies to Achieve Net-Zero Energy Homes(Science Daily, May 15, 2013)

Today we review a guide to build new homes or restructure old homes to achieve net zero energy which is defined as “buildings that generate as much energy through renewable means as is consumed by the building”. The guide is broken down to address design technology and equipment as well as the challenge of resistance to change in terms of human behavior. Such adverse side effects of more air tight houses and the impact on indoor air quality are discussed. The goal of the federal government is to realize 50% of all commercial buildings in the USA to be net zero by 2050. netzero house  

Key Quotes:

 “Key Questions:
  • What are the key characteristics of future NZE homes and the residential building community?
  • What are the challenges and barriers that impede the design, construction, and purchasing of NZE homes?
  • What are the potential concepts that could be included in a future guidance document for the residential building community to aid in the design and construction of NZE homes? “
“Some NZE concepts (e.g., tighter building envelopes) could potentially impact indoor air quality (IAQ). IAQ control technologies, such as heat recovery ventilation, novel ventilation concepts, and approaches to reducing outdoor air requirements, will support net-zero homes by ensuring that indoor environmental conditions are maintained and potentially improved.”

“Risk factors include those related to the adoption of unfamiliar technology; limited ways to measure the performance and benefits of technology; a lack of integration of NZE concepts into current financing mechanisms; and cost (both initial and operating costs). Risk aversion or a reluctance to change was identified as one of the most important barriers because it translates into reluctance on the part of builders to incorporate new technologies with unfamiliar performance histories. “

“Externalities that exert influence outside the domain of the home design and building industry can also create impediments. Diversity and inconsistency in energy policies at the federal, state, or local levels creates uncertainty about investment decisions that involve energy efficiency or on-site electricity generation. “

"Consumers require information that is useful, timely and understandable to be able to make the energy purchase and consumption decisions necessary to achieve net-zero energy for new and existing homes,"

How To Develop Resilience to Rare Extreme Events

Climate Risk and Resilience: Securing the Regi...

General Resilience to Cope with Extreme Events(12 page pdf, Stephen R. Carpenter, Kenneth J. Arrow, Scott Barrett, Reinette Biggs, William A. Brock, Anne-Sophie Crépin, Gustav Engström, Carl Folke, Terry P. Hughes, Nils Kautsky, Chuan-Zhong Li, Geoffrey McCarney, Kyle Meng, Karl-Göran Mäler, Stephen Polasky, Marten Scheffer, Jason Shogren,Thomas Sterner, Jeffrey R. Vincent, Brian Walker, Anastasios Xepapadeas and Aart de Zeeuw, Sustainability, Nov. 28, 2012) 

Today we review an article that looks at resilience when faced with extreme events, an especially timely topic given the recent hurricanes, droughts, forest fires, storm surges, earthquakes and tidal waves and the expectation that climate change will increase the frequency of rare weather-related disasters. Among the key activities and outlooks needed in advance of such disasters is the need to combine long term considerations into short term planned actions and the usefulness of such tools as planning alternate scenarios to identify needs.  

Key Quotes: 

 “Resilience, in the context of environmental management and sustainability, is the capacity of a social-ecological system to absorb disturbance, reorganize, and thereby retain essential functions, structures and feedbacks”

 “rare or unprecedented disturbances that are unusually intense or extensive require a more broad-spectrum type of resilience” 

“Monitoring—the provision of transparent, relevant information about status and trends of the socialecological system—is essential for building and maintaining resilience. Indicators of social processes and the ecosystem help users and managers understand status and trends of critical ecosystem services. Sometimes indicators may provide early warnings of approaching thresholds”

 “seven principles for enhancing resilience, which address
  • diversity,
  • connectivity,
  • feedbacks and slow variables,
  • polycentric governance,
  • learning and experimentation,
  • breadth of participation, and
  • the complex adaptive characteristics of social-ecological systems”
“Scenario planning is a method of exploring the resilience of a social-ecological system to a wide range of factors. Scenarios are a coordinated set of stories that reveal sharply different alternative futures for a social-ecological system. The alternate scenarios within a set diverge as a result of human decisions, diverging drivers, and large-consequence events.”

“The greatest challenge of general resilience is to design and implement concrete policies and actions. Unless incentives are constructed properly, short-term decision making will tend away from the long term view that is needed to build and maintain general resilience. How can long-term practices be woven into actions that also meet the immediate needs of people and ecosystems?”
