Trees cool air, slow runoff, and boost students and public health. Should trees be seen as a public utility which all must be able to access?

Benefits of trees include slowing stormwater runoff, cooling air temperatures, and even boosting student achievement and public health. Trees capture more than a third of rainfall, according to the U.S. Environmental Protection Agency (EPA), easing the strain on flooding and stormwater infrastructure. Their shade helps lower energy use by nearly half, according to the EPA, while reducing carbon emissions by …

Our Climate as an Infrastructure Asset

January 16, 2020  |  By RMI Oriana Tannenbaum and Rushad Nanavatty Our climate is getting plenty of attention, but we don’t often view it as infrastructure. We should. The global climate comprises an essential and massive part of the natural systems that form the foundation for our world and our society. Our economy is built on assumptions about climate stability. Our real …

Low-Carbon Cities Are a $24 Trillion Opportunity

Researchers found that investing in 16 low-carbon measures in cities could cut global urban emissions by 90% by 2050 and has a net present value of almost $24 trillion, equivalent to nearly one-third of the global GDP in 2018. This means that between now and 2050, the total benefits of these investments will exceed their total costs by almost $24 …

Nuclear industry report says nuclear energy is too slow, too expensive to save climate

Reuters, 23 Sept 2019 by Marton Dunai, Geert De Clercq BUDAPEST/PARIS (Reuters) – Nuclear power is losing ground to renewables in terms of both cost and capacity as its reactors are increasingly seen as less economical and slower to reverse carbon emissions, an industry report said. In mid-2019, new wind and solar generators competed efficiently against even existing nuclear power plants …

Surprise! AAA Survey Finds Large Vehicles Cost More To Own Than Small Vehicles. Also, how to visualize your emissions.

Front Range Cars Release 15 Million Tons of Carbon per Year. Here’s How to Visualize All of It — and Yours. Picture a cube measuring 27 feet on each side according to the United Nations. That’s roughly three stories high. In 2009, artists created the first “climate cube,” a life-size sculpture displayed at the UN Climate Change Conference in Copenhagen (video). The …

What is equitable and cost-effective investment in transportation? How is that changing?

Moving forward, MassDOT plans to target certain bottlenecks while taking a more active role in managing how the roads operate, clearing crashes more quickly, and working to improve people’s travel options throughout the state. New construction and technological solutions will help, but the agency will also evaluate smart pricing strategies in the most congested areas. Rail, bus, and other commuter …

Can we reach 100% renewable energy in time to avert climate catastrophe? So far the only consensus is that we need to do it.

Renewables can and be scaled up in time to meet the world’s energy demands across the three main sectors (electricity, heating and transportation). Renewables in the transportation and heating sectors will have to expand in the next few years if the worst impacts from climate change are to be avoided. Delucchi’s recent cost analysis of clean energy systems didn’t include options like …
