The Case for Portland-to-Vancouver High-Speed Rail

Austria rolled out the KlimaTicket, an annual pass that gives the holder access to all forms of public transportation in the country, to encourage increased use of public transport with an eye toward climate change mitigation. The uptake has exceeded expectations with 134,000 tickets sold within just the first two months, but it's still unclear what effect the program will have on the country's carbon emissions.

With the prices of solar technology dropping and the opportunity to save drastically on energy usage and costs, businesses and organizations across the country are investing more in solar infrastructure for their buildings and facilities. The Better Buildings Initiative of the US Department of Energy is helping by providing guidance and documenting effective approaches and financing for renewables installations - from hotels, to schools, to big box retail.

As Beijing grapples with pollution caused in large part by the increase in cars on the roads, a tech-based solution has appeared in the form of forward-thinking bicycles. The Chinese bike-sharing system, spearheaded by several startups, allows commuters to find a bike using GPS, pay for it using an app, and drop it off upon arriving to their destination, wherever that may be. A mix of private investment and government support has allowed this market to thrive.

Copenhagen is a highly livable city, thanks to policies that focus on making streets safe and convenient to walk. The bigger the city, the worse it is to design urban spaces only with cars in mind, says planner and architect Jan Gehl. His top advice is to gather data about people and their movements, making pedestrians as visible in city planning as automobile traffic.

Rather than museum worthy, beautiful crafted artworks made to stand the test of time, the Below the Surface exhibition and website displays the hundreds of years of detritus pulled from an Amsterdam construction site. The website allows visitors to interact with these objects and explore the changes in tools, usage, and culture over Amsterdam’s history.

The consumption of meat and dairy has long been deemed a leading cause of climate change, yet production continues to rise. To contribute to environmental sustainability, Dale Vince – owner of the U.K.’s Forest Green Rovers soccer team – has achieved the status of having the world's first carbon neutral team. From vegan-only menus to a solar-powered grass-cutter, the organization is bringing light to this topic in front of a new audience.

Central District, a historically black neighborhood in Seattle, is getting a makeover to better align it with its roots. Africatown is a nonprofit community land trust that is using its influence to bring Afrocentric design standards to the neighborhood as well as spurring economic development and construction of affordable housing. One real estate project includes a community mural, more gathering space for residents, and local government support.

Funded by federal grant money, the state, and the Office of Naval Research, Hawaii County public transit has developed its first hydrogen-powered shuttle bus. What’s been called the “fuel of the future,” hydrogen fuel cells create a power source that’s only emissions are clean water vapor. While a seemingly viable and scalable clean-energy source, such development and infrastructure requires large financial investments that many states have yet to prioritize.

A startup called WhereIsMyTransport has helped cities create timetables and route maps of informal public transit. The group sends data collectors out to ride local minibus routes, for example, then organizes the information for government officials and others to use to improve trip planning services and more.

Pennsylvania law is preventing a Philadelphia neighborhood from converting an empty lot into a solar farm, but community members are working to fight against this by citing neighboring states that are seeing positive impact from similar projects. One such project is in Massachusetts where shared solar energy systems is helping to offset "80 percent of the power needs of a nearby assisted living facility, an affordable housing development, a family-owned hardware store and a non-profit serving those with disabilities."
