Action Alert: Support AB 2045 Urban Forestry Act

Sign on to a support letter from Sustainable California

Sustainable California is collecting support for Assembly Bill 2045, authored by Assemblymember De La Torre, which will update and broaden the Urban Forestry Act of 1978. The Act has language that directs the California Department of Forestry and Fire (Cal Fire) in administering its urban forestry program. The Act is now in its 30th year, during the height of activity around reducing greenhouse gas emissions and the effects of climate change. It is an opportune time to make update the Act to highlight the role that urban forests play in reducing greenhouse gases, improving air and water quality, conserving energy and water, and providing recreation and other environmental benefits.

Please show your support for this bill – below is a copy of a support letter to Assemblymember Hector De La Torre, the author of the bill. If you would like to sign on to the letter, please email jessica@csgcalifornia.com or fax 916-553-3071 Attention: Jessica your name and organization, no signature is required. We will collect names in support of the bill and submit a group support letter from Sustainable California.

RE: Assembly Bill 2045 (De La Torre) – SUPPORT

Dear Assemblymember De La Torre,

On behalf of Sustainable California, a group of organizations focused on urban sustainability policy development and funding programs, we write to express our collective support for Assembly Bill 2045, which would update the Urban Forestry Act of 1978 to reflect the many benefits of urban forestry.

The benefits of urban forests are wide ranging and varied. They improve community and neighborhood aesthetics, and thereby provide economic and social benefits. Urban forests also reduce green house gas emissions, improve air quality, reduce urban heat island effects, sequester carbon, filter air pollutants, and conserve energy by shading homes and buildings. Urban forests also absorb water and keep soil intact, and thereby reduce stormwater flows and keep pollutants out of our water.

AB 2045 would build upon and expand the benefits of the existing Department of Forestry and Fire Protection (CalFire) Urban Forestry program and other programs the state may develop related to urban greening and urban sustainability.

AB 2045 helps provide more attractive and livable California communities through urban forestry programs and projects that provide multiple benefits, including improved air and water quality, energy and water conservation, climate change mitigation, and recreational and other community benefits.

We collectively support AB 2045 because it supports urban forestry and other urban greening activities in California communities. We believe urban forests, and the environmental and social benefits they provide, are a vital component to moving California forward. We thank you for considering this bill.

With best regards,

Emerging Issue: Capturing Carbon in Your Community: New Reporting Protocols for Tree Planting Projects

Planting and stewarding trees is one of the best ways to capture and store carbon for climate protection, while at the same time enhancing quality of life where we live, work, and play. Over the course of its life, a tree can store 10,000 lb of carbon dioxide (CO2), or 4.5 metric tons (t) (McPherson and Simpson 1999). Also, if planted strategically, a city tree will lower energy use and thereby reduce greenhouse gas (GHG) emissions at the power plant. In hotter climates, like California’s Central Valley, the GHG benefits from energy conservation can exceed those of carbon storage.

The California Global Warming Solutions Act of 2006 (AB32) requires a reduction in GHG emissions to 1990 levels by 2020. This amounts to a reduction of 173 Mt (million tons) from the predicted level in 2020. Our initial research suggests that planting lots of trees in California communities can make a difference when it comes to fighting climate change. Using aerial photography, we found 242 million empty tree planting sites in California cities (McPherson and Simpson 2003). If 50 million trees were planted, they would sequester about 4.5 Mt CO2 (million tons) annually. If they were planted strategically to shade east and west walls of residential buildings, they would reduce air conditioning energy use by 6,408 GWh, equivalent to an average annual CO2 equivalent emission reduction of 1.8 Mt. The estimated total CO2 reduction of 6.3 Mt annually is 3.6% of the 173 Mt statewide goal.

Given that urban forestry can be a win-win investment, a stakeholder-driven process has developed a credible but simple approach for accounting and reporting GHG benefits from urban tree planting projects to the California Climate Action Registry. Reporting carbon reductions to the Registry guarantees their credibility and accuracy in the eyes of regulators and investors. Although originally designed for California users, the Urban Forest Greenhouse Gas Reporting Protocol (UFP) can be readily transferable to other states and countries.

Underpinning the UFP is new science quantifying effects of urban forests on GHGs. A new technology, the Center for Urban Forest Research’s Tree Carbon Calculator (CTCC) is a companion to the UFP that translates research into a useful tool. The Excel spreadsheet provides numerical data on carbon storage, energy savings, and biomass volumes for common tree species in California cities. Together, the UFP and CTCC will put a wealth of science-based information at your fingertips.

The UFP provides a reporting process for GHG tree projects that will permanently increase carbon storage. GHG emissions released by motor vehicles and equipment used to maintain project trees are also reported. In addition to GHG benefits related to carbon storage, project developers are encouraged to report a project’s GHG emission reductions related to energy conservation and use of tree residue as feedstock for biopower plants. Guidance for reporting carbon stored in wood products is under development. Some key aspects of the UFP follow.

- The UFP is aimed at three users: cities, utilities, and college campuses
- A 100-year project reporting period guarantees the long-term existence of carbon storage gains from urban forestry projects
- Planting at least 1,000 project tree sites is recommended
- All project tree sites must be inventoried at least once every ten years
- Procedures are presented to track changes in the levels of care and spending for existing (nonproject) trees
- One goal of the UFP is to ensure that entities are sustaining their existing carbon stocks before engaging in new GHG tree projects
- If the actual amount of carbon stored by project trees differs from the forecast by more than 10%, the forecast must be reviewed and updated as necessary
- An initial project report is required that includes a description of existing tree resources, a project description, maintenance plan, a baseline, and a forecast of future carbon storage and other GHG benefits from project trees for the 100-year period.
- Once a GHG tree project is underway an annual monitoring report is required that includes documentation of compliance with expected levels of service for tree maintenance, quantification of the CO2 stored and released via tree care activities for that year, any significant (≥ 10%) differences between the actual CO2 and the projected level, quantification of other GHG benefits (optional), and a description of monitoring techniques.
- Initial and annual monitoring reports are reviewed by an independent verifier hired by the project developer.

Currently, reporting activities that generate emission reductions is voluntary and there is a substantial demand for quality GHG emission reduction credits. Many organizations and individuals look to the voluntary carbon market for the purchase of GHG emission reduction credits that they can use to offset their GHG emissions and, in some cases, to demonstrate carbon neutrality. Once adopted by the Registry, the UFP sets the stage for significant investment in large-scale tree planting projects. New investments in our community forests have the potential to transform how our cities look, feel, and function. To make that potential a reality will require new knowledge, improved practices, and stronger partnerships.
