On the subject of architecture and construction’s contribution to climate change, our existing building stock is coming under increasing scrutiny. While the United Kingdom recently announced a review into embodied carbon in buildings, thanks in part to the Architect Journal’s RetroFirst... View full entry
Buro Happold and the Battery Park City Authority have published a 10-year sustainability plan that aims to achieve carbon neutrality for the 36-acre district situated on the southern tip of Manhattan by 2050. The district, which sits just beside the World Trade Center site, contains over... View full entry
In recent decades, architects, developers and policymakers seeking to lower the carbon footprint of buildings have focused on reducing energy use by improving the efficiency of lighting, heating and other systems. To lower emissions even further, they are looking beyond such operational matters to the carbon emitted in the production and transportation of the materials that make up the structures, or so-called embodied carbon. — The New York Times
Jane Margolies of The New York Times surveys advances in concrete decarbonization strategies, highlighting a set of concrete manufacturers that are using novel additives and different concrete recipes to save on carbon emissions. Margolies takes a look at LafargeHolcim, Solidia... View full entry
As Democratic presidential contender Joe Biden moves to set out a concrete policy regime to counter that of President Donald Trump, the Biden campaign's "Unity Task Force" coordinated with supporters of former presidential candidate Bernie Sanders has announced a slew of progressive policy aims...

Local Laws 92 and 94, which went into effect on November 15, 2019, require all new buildings and major roof alterations to be capped with a green roof, solar panels, or some combination of the two.
If successful, the new policies could transform New York’s skyline.
— Urban Omnibus
In their publication Urban Omnibus, The Architectural League of New York asked experts from the Green Roof Researchers Alliance to elaborate on the implications of NYC's ambitious decarbonization legislation, the Climate Mobilization Act, which — since November 2019 — requires all new...

Perhaps the biggest risk is that the appeal of natural-sounding solutions can delude us into thinking we’re taking more meaningful action than we really are. It “invites people to view tree planting as a substitute” for the sweeping changes required to prevent greenhouse-gas emissions from reaching the atmosphere in the first place, says Jane Flegal, a member of the adjunct faculty at Arizona State University’s School for the Future of Innovation in Society. — MIT Technology Review
James Temple, writing in the MIT Technology Review outlines the argument against viewing tree-planting as a climate crisis silver bullet. While planting trees might seem like a quick and easy way of helping to abate the climate crisis, Temple explains, increasingly, researchers are finding that... View full entry
With a new Executive Directive issued by Los Angeles Mayor Eric Garcetti, the City of Los Angeles has become the latest California municipality to make a plan to decarbonize its municipal building stock. Under the recently unveiled Executive Directive No. 25, L.A.'s Green New Deal: Leading... View full entry
[...] a team of Canadian science and engineering graduates is pitching a dream to plant a billion trees by 2028 using drones. The project is dubbed Flash Forest and combines the use of drones with specially-designed pods and an accelerated seed germination process. According to Flash Forest, its technology can plant trees 10 times faster than a single worker and at a cost that is 80 percent cheaper than traditional tree planting methods. — New Atlas
On their Kickstarter page, the team behind the Toronto-based Flash Forest project explains what happens before and after heavy-lift drones pneumatically fire their custom-designed seed pods into the ground: "Before we plant our pods, we pre-germinate the seeds inside using our own 'secret sauce.'...

Now that California has reached 1 million solar roofs, some activists are looking at battery storage as the next frontier for lawmakers.
Dan Jacobson, director of Environment California, thinks the state should aim to install 1 million batteries by 2025. Those systems could store solar power for use in the evening — and help homes keep the lights on when utility companies intentionally shut off power to reduce the risk of wildfire ignitions.
— The Los Angeles Times
Writing in The Los Angeles Times, Sammy Roth reports on California's 1 million solar rooftop achievement, the culmination of a solar incentive plan initiated by Governor Arnold Schwarzenegger in 2006. According to the report, there are now more than 1,046,792 solar installations in the state... View full entry
The McHarg Center at the University of Pennsylvania has published a digital atlas that attempts to communicate the wide-ranging implications of both climate change and a potential Green New Deal for the United States. A color-coded breakdown of land uses across the country that includes... View full entry
Denmark is developing plans to build “energy islands” – areas of reclaimed land that would host vast wind farms able to generate up to 10GW of electricity, 8.8GW more than the largest offshore wind farm now in existence.
The cost of the project or projects has been put at between $20bn and $45bn, most of which is expected to come from the private sector, with the government funding research and development.
— Global Construction Review
With 41% of its national energy mix already generated by wind turbines, Denmark leads the field in Europe in terms of percentage. A recently passed National Climate Act signals further commitment to set bold and legally binding emission reduction goals. View full entry

With support from the Carbon Neutral Cities Alliance’s Innovation Fund, [Vancouer] collaborated closely with the building industry and its partners, and, in 2016, Vancouver’s City Council approved a Zero Emissions Building (ZEB) plan. That plan launched a bold commitment to make near-zero emissions homes and buildings the new normal in Vancouver by 2030. Few cities had yet gone that far. — Fast Company
Writing in Fast Company, Sean Pander, green building manager for the city of Vancouver, lays out the multi-faceted approach the Terminal City has taken to chart a new course with regards to carbon emissions generated by the city’s buildings. The effort, according to Pander, involved... View full entry
