Carbon Leadership Forum (CLF) related news and media.

Carbon Leadership Network Local Chapters are springing up! Anthony Pak of Priopta led the charge by creating the first local chapter in Vancouver. Network members Kristina Miele, Martin Torres, Victoria Herrero-Garcia, Vaclav Hasik, and Miguel Angel Lopez have followed suit by starting chapters in New York City, Austin, Denver, San Francisco, and Chicago, respectively. More chapters have started as well, in Atlanta, Boston, Calgary, Hong Kong, Pittsburg, Portland, Colorado, Seattle, and Toronto. Local chapters help interested professionals share best practices, discuss solutions, and spread the word about embodied carbon. More information will be coming soon about guidelines and best practices for starting your own chapter. Help grow our community by fostering important local interactions!

The Embodied Carbon in Construction Calculator (EC3) was released to the public in November at Greenbuild 2019 in Atlanta. This tool allows users to access and contribute to an EPD database to better quantify, report, and reduce embodied carbon. EC3 incentivizes LCA supply-chain accountability by highlighting sources of uncertainty, identifying and encouraging methods to lower embodied carbon, and monitoring industry-wide progress over time. Keep an eye out for webinars and training sessions, but for now you can engage with other users online at

Buy Clean and Buy Fair Washington Act (HB 2744) - This bill was officially introduced with five sponsors: Representatives Beth Doglio, Davina Duerr, Lauren Davis, Joe Fitzgibbon, and Alex Ramel.

House Energy & Commerce Committee releases a comprehensive, economy-wide emissions reductions bill called the CLEAN Future Act to require all retail electricity suppliers to obtain 100 percent clean energy by 2050.

Embodied Carbon enters the building code in Marin County - Marin County is adopting a low-carbon concrete code. Thanks to the core development team - Alice Zanmiller (Marin County), Kate Simonen (Carbon Leadership Forum), Frances Yang (Arup), Miya Kitahara (StopWaste) and Mark Aschheim (Santa Clara University).

SE 2050: Structural Engineers Unite against Climate Change - Calling all structural engineers to understand and reduce embodied carbon in their projects to help the building sector go carbon neutral by 2050. Declare your individual or organizational support for the SE 2050 Challenge on this page.

World GBC Report: Bringing Embodied Carbon Upfront - This report lays out a bold vision for reducing embodied carbon over the next several decades. The 67-page document provides state-of-the-market analysis and a detailed breakdown of specific goals for a variety of stakeholders.

LETI Embodied Carbon Primer (ECP) outlines best practices for architects, engineers, interior designers, and urban designers to achieve ambitious embodied carbon reductions. This document supplements LETI’s Climate Emergency Design Guide.

Embodied Carbon Guidance from ILFI - This document provides support for and clarification of the embodied carbon requirements in both the Living Building Challenge 4.0 Energy Petal and Zero Carbon Certification. The document discusses best practices for reducing embodied carbon in building projects. Contact Haley Gardner with feedback or questions.

Forests, Wood & Climate, a Sierra Club report, makes the case that building with wood will only help reduce carbon emissions if it is coupled with improved forest protection, restoration, and stewardship: specifically, the conservation of carbon-rich primary forests on public lands and a transition to climate-friendlier forestry on private lands. The Sierra Club calls for practices and policies that support climate-friendlier forestry and a Forest Carbon Trust on federal property.

GatesNotes: Buildings are bad for the climate - Bill Gates gave a shout out to the launch of EC3 in this blog post where he breaks down the importance of embodied carbon and sustainability in the building industry.

Understanding emissions timeframe used in EPDs -. LCAs typically use a 100-year time frame for GWP but given the time-sensitive nature of the climate crisis, this might not be the best approach. CO2 can persist in the atmosphere for thousands of years, whereas HFCs, which are used as blowing agents for spray foam and XPS insulation, can dissipate in as little as 5 years. Timeframes matter.

99% Invisible: Built on Sand - Discussion on the environmental impact of sand in construction and a conversation between ECN Co-Chair Kate Simonen and 99% Invisible host Roman Mars about embodied carbon.

NRG COSIA Carbon XPrize Competition is a global competition with a $20 million prize for developing breakthrough technologies that will convert CO2 emissions into useful products. Three out of the ten finalists are addressing CO2 in concrete (CarbonCure, CO2Concrete, Carbon Upcycling Technologies)

Rethinking Timber is a strategic overview conducted by Arup of timber construction and its recent upsurge in popularity. Seven perspectives on the use of timber in building design are considered: (1) managing our carbon budget, (2) urban densification, (3) wood and well-being, (4) the future is prefabricated, (5) sustainable sourcing, (6) knowing the material, and (7) innovating with wood.
