Proffers for New Development in Fairfax County, Virginia  

Fairfax County established Transportation Demand Management (TDM) requirements (“proffers”) for new development that would have significant traffic impacts. For buildings within the urban centre of Tysons, trips had to be reduced between 25% and 65% during peak hours, depending on the size of the building and its proximity to the Metrorail stations. The county proffers required large new properties to annually monitor trips, conduct tenant commuting surveys, and show that they were meeting their trip reduction goals. They also had to conduct surveys every three years. Over seven years, 13 such developments generated 63% fewer trips, which was 34% beyond their goals. For the office buildings, this was likely at least partly a result of more people working from home during the COVID pandemic.

Carpooling Promotion in Paris  

France provides financial incentives to local travel authorities (LTAs), employers and employees to promote carpooling. It also funds the development of carpooling infrastructure, ridesharing platforms that make it much easier to carpool, and fraud prevention mechanisms. This case study covers the formative research and early implementation in Paris of France’s National Daily Carpooling Plan.

Coolfood

Smart Trips Austin  

Smart Trips Austin encourages residents of Austin Texas, USA to take multi-modal transportation options (walk, bike, ride transit, and share rides) more often, rather than drive alone. The program focuses on personal interactions — educating individuals on their options and overcoming barriers to multi-modal travel. Smart Trips reinforces this new information using community-based programs such as learn-to-ride classes, transit instruction, and group walking activities. Initially, the program targeted residential neighbourhoods of Austin Texas; each year a different area was targeted. In 2020 the program expanded to city-wide and began to segment using a Stages of Change approach. In 2021, it started targeting residents who had recently moved to or around Austin. Smart Trips Austin averaged a participation rate of 5-10% of households contacted, a 5-10% reduction in drive-alone trips among participants (about 41,000 vehicle trips per year), and a corresponding 5-10% increase in active and shared trips. This account of the program was designated a Landmark case study in 2023, making the City of Austin one of the few governments with more than one program designation. 

Fridge Night / Use Up Day  

The Fridge Night programme offers simple, practical solutions to help people be more resourceful with and enjoy eating the food they have at home, thereby reducing food waste and associated greenhouse gas emissions. Participants pledge to use up expiring perishables one evening a week for a month, and complete weekly challenges. They are sent reminders and tips. In return, they save time and money and get tools for easily planning meals with leftovers.

Flashfood  

According to Second Harvest, almost 60% (35.5 million metric tonnes) of food produced in Canada is wasted annually. Roughly 32% (1.2 million tonnes) is still edible. The app informs users about local food nearing its best before date, often discounted by 50% or more. While some items may only be usable for a day or two, others can last for weeks – especially if frozen or cooked. The Flashfood app enables food stores to sell food that would otherwise be thrown out, while reducing their carbon footprint.  Consumers are able buy food that they would otherwise deem too expensive.

Co-Ownership of Wind Farms  

What if you want to move away from gas and oil, but rent, are about to move, or can’t afford solar panels? If your energy supplier has not already pledged to go green, you have few options. The co-ownership of wind farms engages and makes it practical for more homeowners and renters to buy wind-generated power.

Liftshare and Mobilityways, U.K.  

Liftshare is a social enterprise that has worked with over 700 of the UK’s largest employers to reduce the number of single occupancy vehicle trips using carsharing, active transportation and public transit when commuting for work. With an online community of over 1 million members, it is estimated that Liftshare members have avoided the release of 300 million kg / 300,000 tonnes of commuter carbon emissions (averaging 50 million kg / 50,000 tonnes per year). In 2020, Liftshare launched Mobilityways, a sister platform that enables employers to evidence, track, plan and change their commuter emissions via a set of tools / modules that work seamlessly together.

Southern Nevada Water Authority's Water Smart Landscapes Program  

As climate change leads to more drought situations, it will be important to understand how to best promote water conservation. Southern Nevada Water Authority’s Water Smart Landscapes (WSL) program pays homeowners to replace their non-native, ornamental lawns with plants and landscapes that use less water because they are better adapted to their dry climate. It is one of the longest running “cash for grass” policies. Designated a Landmark case study by our climate change peer review panel in 2022.
