Home heating is largest use of fossil fuel in buildings, which are the largest source of GHGs in urban areas: It’s time to incentivize residential heat pumps. 5 to 8 million buildings add or replace heating equipment each year

5 to 8 million US buildings will add or replace heating equipment each year. Each one of these decisions may lock in fossil fuel use in buildings for decades since gas furnaces have a 15- to 20-year lifetime. June 8, 2020  |  By RMI. Claire McKenna, Amar Shah, Mark Silberg The United States has made significant progress decarbonizing the electricity sector in recent …

Why Carbon Taxes Are Still in the Mix

Clean Technica, June 14, 2020 Renewables are now competitive with traditional technology for new electricity generating plants. The below chart simplifies data from the 2019 Lazard report by taking the midpoint of the range for each technology: The blue bars above show the total LCOE for each technology. As you can see, utility-scale solar and onshore wind are now cheaper …

Large cities may cut emissions by a third based on improvements in housing density alone. Reducing driving is essential

Patrick Sisson at Curbed pointed out recently that some studies have estimated that large global cities could cut their emissions by a third based on improvements in housing density alone. We have to start talking about these solutions and making them part of mainstream environmental policy, Hankins says. Time is running out. “We can’t afford to ignore significant climate mitigation measures just …

Honolulu, NYC and Boulder lead clean energy resilience plans

Katie Pyzyk@_PyintheSky Jan. 31, 2020, Smart Cities Dive Honolulu and New York City are top-scoring U.S. cities for incorporating energy efficiency and renewable power policies into resilience plans, according to a study from the American Council for an Energy-Efficient Economy (ACEEE). They ranked “exemplary,” while Atlanta, Chicago and Washington, DC followed close behind. The study concluded that many cities are taking steps toward …

US leads in per capita and total emissions. It’s time to shut off fossil fuel development.

Such concerns led Philip Alston, the UN special rapporteur on extreme poverty and human rights, to declare that climate change is “an unconscionable assault on the poor” in a report to the Human …

The remaining carbon budget

The estimate of global warming up to the present day; The assumed future warming from emissions of non-CO2 forcings such as methane and black carbon and the reduction of cooling sulphate emissions; The amount of warming still in the pipeline once emissions are brought back to zero; The ratio between cumulative CO2 emissions and global warming (also known as the …

CO2 hits over 415 ppm

The concentration of carbon dioxide, the main, long-lived greenhouse gas causing global climate change, in Earth’s atmosphere has reached new heights, according to scientists at Scripps Institution of Oceanography. Why it matters: The new reading of 415.26 parts per million (ppm) on May 11 was the first daily baseline at Hawaii’s Mauna Loa Observatory to eclipse 415 ppm. That observatory has …
