"Two powerful phenomena are simultaneously unfolding on Earth: the rise of the climate movement and the rise of women and girls. The People's Climate March and the Women's March. School strikes for climate and the #MeToo movement. Rebellions against extinction and declarations that time's up. More than concurrent, the two trends are deeply connected. From sinking islands to drought-ridden savannas, the global warming crisis places an outsized burden...

Portland has become a global model of transit-oriented development (TOD). For more than 40 years, city planners have integrated transport decisions into urban growth and development efforts. The result: Portland is consistently ranked as one of the country's most livable cities, boasting a healthy two percent population growth annually - and the second-lowest per capita transportation spending of the 28 largest U.S. metropolitan areas.

In 1990 European physicists set out to test the limits of cost-effective energy efficiency. The result was the first passive house, a four-unit townhouse that combined heavy insulation, airtightness, and heat-recovery ventilation to achieve reductions of up to 90% in the energy required for heating and cooling. This program introduces the passive house concept-popular in Europe, but slower to catch on in the States-and showcases some beautiful examples...

"In [this book], the authors outline two possible scenarios for the planet. In one, they describe what life on Earth will be like by 2050 if we fail to meet the Paris targets for carbon dioxide emission reduction. In the other, they describe what it will take to create and live in a carbon neutral, regenerative world. They argue for confronting the climate crisis head on, with determination and optimism. How all of us address the climate crisis in...

Concrete production is a leading cause for climate change today, generating many times more carbon dioxide pollution than air travel and leaving a significant footprint on our environment. This 2009 Falling Walls lecture video highlights Franz-Josef Ulm's nano-engineering of materials, which sets out to eradicate climate change. Ulm investigates the replacement of calcium carbonate, the active ingredient in lime, and the reduction of the massive carbon...
