Seattle's micro-housing booms offers an affordable alternative

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.

Substitutes for city parking requirements are becoming increasingly popular throughout the United States. Rather than using off-street parking, many housing developers now provide residents with alternatives that promote reduced driving. This method is better for the environment and lowers the cost of housing in urban areas.

New York is determined to become a national leader in the renewable energy sector, and they are leveraging numerous approaches to help integrate better and more environmentally conscious technologies into the grid. The multi-faceted approach includes updating laws and regulations to be more renewables-friendly, hosting competitions to foster entrepreneurship and creative solutions in the field, piloting new technologies, and creating better incentives for utility companies.

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.

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."

Auraria Campus in Denver installed more than 2,100 solar panels on their school’s library, which will save students money and be more sustainable. The campus teamed up with Namaste Solar to build the $1 million solar array, which will reduce campus energy usage by about 2.5 percent annually. While it will take 15 years for the panels to recoup the cost of installation, the life of the project should be about 30 years, so it will also generate additional revenue for the school.

Solar energy is a clean, cheap, renewable, and land-efficient resource, making it a valuable technology to scale up in the face of climate concerns and clean energy. Diversifying the supply chain for creating and sourcing solar panels can help make solar energy more reliable when faced with geopolitical and human rights issues.

Hempcrete, a combination of hemp, water, and lime, can be used as a more sustainable insulation option for buildings. The material improves energy efficiency, produces less carbon than options like fiberglass and foam, and will continue to capture carbon while used as insulation.

KC Tenants is a tenant union that connects renters to put pressure on landlords and local government to protect tenant rights. With the help of the group’s political arm, KC Tenants Power, they have blocked thousands of evictions, received millions of dollars in funding to secure affordable housing for those in need and have grown to about 10,000 members. Outside of blocking evictions and securing long-term affordable housing, the group also has four members who won City Council seats.
