Most Recent Climate Change Case Studies

Norway’s Promotion of Electric Vehicles  

Several policies / incentives, in place over an extended period, have made Norwegians more likely to purchase electric vehicles (EVs) than people in any other country. These incentives have included: exemption from vehicle registration and high purchase taxes, reduced road tolls, free parking, and access to some bus lanes. A similar long-term approach could be adapted for other big-ticket purchasing behaviors where the impact justifies the expense – for example energy-efficient home / building retrofits and appliances. Norway's electric cars are close to zero-emission as 98% of its electricity came from hydropower.

Climate Matters Program for TV Weathercasters  

Climate Matters trains and supports American TV weathercasters to report on the local impacts of climate change while reflecting current scientific knowledge and concerns. The program provides participating newscasters with weekly story packages with local data and broadcast-quality graphics that visualize the data. Because of an overt conflict in the meteorology community about opposing views of climate change, the program engaged a conflict mediator who worked with small groups of opinion-leading weathercasters to surface and work through the entrenched conflicts. As climate reporting became increasingly normative, the program ensured that everyone in the weathercasting community knew the behaviors were gaining in popularity. As of 31 October 2020, there were 968 participating weathercasters in 483 local TV stations, in 92% of all US media markets and 99 of the top 100 media markets. Viewers exposed to their climate education became more likely to understand that climate change is already a 'here, now, us' problem.

Seattle’s Just One Trip Phase II  

Just One Trip Phase II illustrates the use of Propensity Modelling / Predictive Analysis, Street Ambassadors, Quality Online User Experience (UX), and trip planning to reduce the proportion of single-occupant car trips in Seattle WA, USA. It engaged over 21,000 people and on average participants reduced four drive-alone trips per week per person. Designated a Landmark case study in 2020.

City of Austin’s Leave Time Travel Incentive  

The City of Austin reduced employee commute travel by one million vehicle miles within six months of making its Leave Time Reward (LTR) a permanent incentive. During this period, the percentage of drive-alone trips fell from 53% to 41%. Attribution of these impacts to the City’s time off incentive policy is strengthened because that policy was introduced in the pilot study, then withdrawn after the pilot, then later reintroduced for the permanent program (Reversal Design.) Designated a Landmark case study in 2020.

California’s Energy Conservation Competition  

Participants in California’s Energy Conservation Competition work to change energy conservation behaviors in their schools relating to lighting, plug-loads, and mechanical systems. They also develop campaigns to encourage fellow students to communicate with teachers, peers, and administrators about energy conservation practices. This comprehensive program cuts school energy bills by 5% to 15%, and integrates climate education and energy efficiency, with linkages to hands-on job training and career development. Designated a Landmark case study in 2020.

Day Zero: Cape Town Uses Fear Appeal to Avoid Running Out of Water  

Fear appeals must be carefully considered as they can too-easily backfire and discourage people from taking in and acting on our messages. And why spread fear unnecessarily? This case study illustrates an appropriate and effective use of a fear appeal to reduce water consumption in Cape Town South Africa. It tracks 30 years, from the time the City predicted severe water shortages to the point where the taps nearly ran dry and this city of four million people reduced water use enough to avoid disaster. 

Opting Out in Germany for Non-Renewable Energy  

While many people in Germany say they would use green energy if presented with a choice, very few consumers do so. In contrast, most people have been using green energy in a few German municipalities where citizens have had to opt out for non-renewable energy supplies rather than having to opt-in to get renewable ones. This case study presents their experiences and illustrates the value of randomized control trials (RCTs) for measuring program impacts.

Stay on the Ground  

The most effective approach to-date at shifting air travel to train travel, and also at promoting the sale of carbon offsets for airplane travel, this approach could also work well for other behaviors that are perceived by the audience as clearly important to do, yet are not being adopted by many people.

Capitol Hill In Motion  

Capitol Hill In Motion is a recent evolution of the individualized marketing approach used by King County, Washington State, USA. It illustrates how to further engage communities where most trips are already not drive-alone. With remarkably high signup rates, this campaign also delivered a solid 16% average reduction in drive-alone trips (surpassing the campaign goal and King County’s overall goal of a 10% reduction).  Designated in 2017. 

Chicago’s Go Program  

Chicago’s Go Program is an Individualized Marketing program that helps residents walk, bike, ride transit, and use bike share more frequently, while driving alone less often. Compared with past Individualized Marketing efforts in other cities, the Go Programs have pushed the envelope of inclusive, accessible programming that serves a very broad range of Chicago neighborhoods - and the very high participation rates and positive post-program stakeholder input show that this effort paid off. Because of these successes, the Go Program can serve as a model for other communities looking to integrate equity and diversity in Transportation Demand Management programs. On average, 65% of post-program survey respondents report increased walking, biking, or transit usage because of the program. The program’s behavior-changing results led the City of Chicago to designate funding for additional neighborhoods in the future. Designated in 2017. 

ClimateSmart Home Service, Queensland, Australia  

Once a resident signs up for Queensland’s ClimateSmart Home Service, a licensed electrician visits the home, installs a variety of energy-efficiency products, conducts an energy audit, provides recommendations, and leaves behind materials and prompts. The information collected is then used to create a customized plan that is sent to the homeowner approximately six weeks after the visit, with different audience segments receiving different messaging. A voluntary household energy challenge, wireless power monitors and an on-line portal help motivate and empower participants. ClimateSmart was designated a Landmark case study in 2011.

Opower’s Home Energy Report, Minnesota  

This program is a great example of the use of ongoing individualized feedback and prompts, coupled with norm appeals. Opower helps individual utility companies to send customized home energy use feedback reports to their residential utility customers. The full-colour reports include a comparison with other similar households, offer tips and strategies to reduce energy use, and provide seasonal energy consumption information. A web portal offers personalized insights and tips, and tools for choosing an optimal energy rate plan. In addition, Opower offers utilities the opportunity to send text messages directly to customers to alert them when their energy consumption is high and offer ways to reduce it. Updated as of October, 2014.

Burlington’s Ice Rink Energy Competition  

The City of Burlington's Ice Rink Energy Competition employs a low cost, easily replicable approach to significantly reduce energy consumption, associated greenhouse gases (GHG) and energy costs. A friendly competition to reduce energy at eight of the city's ice rinks helps change behaviours among staff and users, improves facility performance, and extends equipment life without sacrificing facility service levels or user satisfaction. Designated a Landmark case study in 2013.

Class 5 Energy  

This comprehensive, long-term approach combines education, training, behavior change and goal setting with progress tracking, recognition and continuous improvement to reduce energy use in schools, hospitals and other institutional settings.

Barrie Water Conservation Program  

The City of Barrie, Ontario has deferred millions of dollars in waste water and water supply capital expenditures with its retrofit water conservation program. The City supplied subsidized ultra low flow toilets, showerheads and aerators to Barrie residents over a two-year period.
