Engineering wind-resilient structures and spaces is a complicated endeavor that relies on both human ingenuity and science. Projects must also mesh with other environmental factors, including falling snow and ice, snow loads and solar conditions. Consulting firms tap detailed climatological data, local wind data and more to grasp how wind affects a structure in a particular spot. But that’s only a start.

Energy‐related carbon dioxide (CO2) emissions decreased by 89 million metric tons(MMmt), from 5,259 MMmt in 2015 to 5,170 MMmt in 2016. Although real gross domestic product (GDP) increased 1.5% over that period, other factors contributing to energy-related CO2 emissions more than offset the growth in GDP, leading to a 1.7% decline in energy-related CO2.

The scientific case for the benefits of trees and urban nature has become more solid over the last few decades. Trees and other natural features in cities can help regulate water quality, water quantity, and the timing of water flow. They can help clean and cool the air, reducing harmful air pollutants and ambient air temperatures. They lend beauty to our streets, enhance citizens’ lives, and significantly increase property values. When you consider all the benefits that street trees can provide to society, there is a strong business case for increased societal investment. One study in California, for instance, found that for every $1 spent on tree planting and maintenance, urban trees deliver $5.82 in benefits.

NRDC’s groundbreaking analysis demonstrates clearly that with bold action on energy efficiency, renewable energy, electrification of vehicles and buildings with clean power, and electric grid enhancements, the United States can reach its 80 percent by 2050 climate goal. Moreover, we can get there at a much lower cost than any comparable study predicts.

As Hurricane Harvey bore down on the Texas coast, Tony Miller, chief executive of a Silicon Valley startup, wondered how he could help. His company, Entanglement Technologies, can measure levels of air pollution in real time, important information for emergency responders and people living near storm-damaged refineries and chemical plants. On Aug. 31, Miller called Elena Craft, Environmental Defense Fund’s Texas-based senior health scientist, and the two quickly came up with a plan to monitor neighborhoods near industrial facilities in and around Houston. Miller was on the road the next day.
