Carolyn Kousky, founder of Insurance for Good and longtime researcher on climate impacts and insurance markets, told MIP and SSTI widespread insurance protects local economies, as well as lenders and mortgage markets. “As a warming planet increases the risks of weather-related extremes, insurance becomes harder to get and more expensive. The only long-term solution is serious investments in risk reduction and climate adaptation,” Kousky said in an email.

The benefits of transit extend well beyond transit riders
Public transit is often viewed by planners and transportation officials as a key strategy for reducing car dependency, easing traffic congestion, and lowering emissions. Every person who opts for transit over driving helps reduce the total miles driven in private vehicles. According to a large national study, however, good transit has a ripple effect on land use and travel behavior. For every mile not driven by transit riders, transit accounts for another six to nine miles not driven among the larger population.
Rural town centers can provide transportation benefits similar to those of urban areas
People living in dispersed rural areas face some of the greatest transportation challenges, according to a new study. However, living in more concentrated rural villages helps alleviate those challenges. Ensuring people can get around without relying on a car—even in rural pockets—is key to meeting their needs more affordably.
Highway costs outweigh benefits, especially when land value is considered
Highway expansion projects rarely deliver the time-saving benefits that policymakers promise. Adding more lanes generally leads to increased demand, more congestion, and higher emissions. A new study finds that economically, these projects usually fall short by about 17% of their projected benefits, and costs are significantly higher when land use is factored into the equation. Due to the historical inefficiencies and limited effectiveness of highway projects in achieving their economic goals, prioritizing transit could lead to greater sustainability and efficiency. While transit projects also can be costly, they often provide more sustainable and long-term travel solutions when compared to highways.
People walking are often blamed for crashes when roads are designed for driving
A pedestrian’s location at the time of a crash often determines who (whether driver and pedestrian) is found at fault, says a new study. Even with a lack of pedestrian infrastructure nearby, pedestrians who cross high-speed arterial roads with bus stops are more likely to be blamed.
Mixed land uses play an important role in social cohesion
Mixed land uses are associated with greater social cohesion, according to a new study. Dense places without diversity, however, can have the opposite effect. As walkable cities become a growing focus of urban planning and decision making, the social impacts on health, vibrancy, and social cohesion are often harder to quantify. The authors use open-source data to quantify and find correlations between urban infrastructure and form types with social cohesion. Understanding these relationships offers insights into the future of urban planning and decision making that balances density, diversity, and community connection.
Land use reform brings it all together for lower emissions
The Biden administration, in accordance with the Paris Agreement, targets a 50% reduction of greenhouse gas emissions by 2030 in order to avoid the most damaging effects of climate change. Because it contributes almost 30% of GHG emissions the transportation sector is a ready focus for transformation. Reducing the amount people drive, increasing the use of transit, building better infrastructure for people to safely walk and bike, and electrification are common goals. But changes to land use policy are often missing from this equation. To this end, the researchers at the Rocky Mountain Institute have begun to examine how changing land-use patterns might help curb GHG emissions.
Reworking the “greatest public works project in history”
The interstate highway system is arguably the largest and most impactful project in American history—not just in terms of its cost and the way it connected businesses and cities across the country, but also because of the devastating impact it had on people of color and low-income communities in central cities. All levels of government played a role in pushing interstates through cities. Now it is everyone’s responsibility to confront the long-term consequences. The federal Reconnecting Communities program marks an important turning point in addressing these impacts, but also represents the beginning of a decades-long process to address and correct past damages.
Low-income communities can benefit most from accessible cities
America’s outward, car-oriented growth has meant that people now travel much farther for basic needs. According to new research, only 12.1% of trips to basic amenities happen within a 15-minute walking radius of residents’ homes in the median U.S. neighborhood, and the frequency of those types of trips varies greatly depending on income.
Evidence shows that car-free streets can reduce traffic
Critics argue that car-free streets do not reduce overall traffic. Several new studies counter these claims and illustrate the benefits of creating areas that put people first.
