Shaping Tomorrow's Built Environment Today
October 19, 2023
In 2022, the United States produced more than three times as much solar, wind and geothermal power than it did in 2013, with growth in all 50 states. That’s according to Renewables on the Rise 2023, an online dashboard unveiled on October 11 by the Environment America Research & Policy Center and Frontier Group. The dashboard compiles information from various sources to detail progress over the past decade in six areas—wind, solar, electric vehicles, electric vehicle charging, energy efficiency and battery storage—that will be key to transitioning to a future powered entirely by clean and renewable resources. Read more
In a growing push to make buildings more resilient to climate impacts, the federal agency vowed on October 12 to give every state up to $2 million next year to improve building codes. The funding from the Federal Emergency Management Agency follows a series of reports showing that most local building codes are archaic and leave millions of people highly exposed to climate impacts. The new FEMA money comes as some state legislatures, under pressure from builders, block plans by state agencies to adopt new building codes. Read more
Across Colorado, thousands of students filing into classrooms this school year are sharing their space with new silent companions. The new arrivals are thousands of classroom air quality monitors and portable air cleaners installed as part of a Centers for Disease Control and Prevention-funded study through the Colorado Department of Health and Environment and the University of Colorado Boulder. A follow-up study, also funded by the CDC through the Colorado School of Public Health at the CU Anschutz Medical Campus and CU Boulder, aims to evaluate the impact of the portable air cleaner operations on the classroom environment. Read more

In Case You Missed It
The U.S. Environmental Protection Agency has finalized standards that will phase out the most climate-warming hydrofluorocarbons (HFCs) in key applications, from aerosols to heat pumps; supermarket refrigerators to vehicle air conditioners. At the same time, the EPA proposed new rules to cut refrigerant leakage, promote reclamation and reuse and mandate the use of reclaimed refrigerant when making and servicing many new products. These EPA rules are two key pieces of the American Innovation and Manufacturing (AIM) Act, the climate law enacted in 2020 to cut the use of these super-pollutants by 85% over 15 years. Read more
