Council Priority: Climate/Sustainability and Climate Action Plan
Summary Title: Carbon Neutral Gas Plan Review
Title: Staff and the Utilities Advisory Commission (UAC) Recommend the
Council Adopt a Resolution Amending the City’s Carbon Neutral Gas Plan to
Continue to Achieve Carbon Neutrality for the City's Natural Gas Supply
Portfolio
From: City Manager
Lead Department: Utilities
Recommendation
Staff and the Utilities Advisory Commission (UAC) recommend the Council adopt a resolution
amending the City’s Carbon Neutral Gas Plan, which includes the following key elements:
• Continue the Carbon Neutral Gas Plan to offset carbon emissions from City natural gas
sales;
• Continue to restrict purchases to carbon offset project types which adhere to California
Air Resources Board (CARB) cap and trade compliance protocols, including U.S. Forest,
U.S. Urban Forest, U.S. Livestock, U.S. Sourced and Destroyed Ozone Depleting
Substances, U.S Mine Methane Capture, and U.S. Rice Cultivation; or any other Project
Type subsequently approved by CARB;
• Restrict purchases to CARB’s vintage requirements;
• Continue to limit transactions to spot1 purchases;
• Rate impacts of individual offset transactions are limited to under $19 per ton of CO2e.
This is consistent with the Council-approved maximum rate impact or 10₵/therm; and
• Maintain a preference for California projects as long as it does not result in a price
premium.
Executive Summary
Palo Alto implemented a Carbon Neutral Gas Plan in FY 2018, staff report 75332 whereby
carbon offsets are purchased to match the carbon emissions associated with all City of Palo Alto
1 Staff identifies spot purchases as buying offsets that have already been created, verified, and are ready to be
sold.

Utilities annual natural gas sales. Nearly four years into the plan, staff is revisiting the plan to
clarify and refine plan parameters and update the community on the activities to date. The
Carbon Neutral Gas Plan is provided as Exhibit A to the Resolution (Attachment A).
Implementation of the Carbon Neutral Gas Plan will be carried out by staff.
Background
Natural gas use by residents, businesses, and City facilities contributes about 150,000 tons CO2e
annually, representing about 30% of the City’s total 500,000 tons CO2e footprint. This total does
not include community greenhouse gas (GHG) emissions such as air travel, transportation, meat
consumption, etc.
In December 2016, Council adopted Resolution 96493, staff report 7533, approving a Carbon
Neutral Gas Plan to achieve carbon neutrality for the gas supply portfolio by FY 2018 using high-
quality carbon offsets with a cost cap of up to 10/₵/therm. Council also directed staff to
develop a Carbon Neutral Gas Plan implementation plan.
The Council-adopted Sustainability and Climate Action Plan (S/CAP) Framework4 established a
goal to reduce Palo Alto’s greenhouse gas (GHG) emissions by 80% compared to 1990 levels by
2030. On December 11, 2017, Palo Alto City Council accepted a 2018-2020 Sustainability
Implementation Plan5 that included a goal to mitigate the impacts of natural gas use through
carbon offsets as a bridging strategy to electrification. Purchasing carbon offsets to mitigate
natural gas emissions and evaluating local offsets is a Council-approved key action.
Given the resolution was approved four years ago, staff is providing an update on the Plan
implementation, performance to date, and proposing refinements to the Plan.
Discussion
Offsets Overview
A carbon offset is a reduction in CO2e emissions to compensate for CO2e emitted elsewhere.
Offsets enable buyers to balance out their emissions. By productizing carbon offsets, a market
is created for buyers and sellers to reduce CO2e emissions, which in turn, incentivizes lower cost
solutions to emission reductions. While carbon offsets are still a relatively young environmental
product, the global market for carbon offsets has seen continued demand growth, and in 2018,
the global voluntary market was estimated at approximately $300 million with cumulative
volume over 1.2 billion metric tons transacted6. There is a robust marketplace for carbon
offsets from both voluntary purchases, similar to those carried out under the City’s Plan, as well
as for compliance purchases, similar to the California Cap and Trade Program.

Offsets balance out pollution across geographies but do not stop emissions from occurring in
Palo Alto. As such, in the hierarchy of climate actions, reducing one’s own sources of emissions
is viewed as superior to carbon offsets created elsewhere. Further, there are inherent
challenges in accurately measuring emission reductions from offsets, and there is greater
certainty in measuring the impact of reducing one’s own emissions. Though, given that
emissions are a global problem, carbon offsets still provide significant value as a tool in a
broader portfolio of climate actions to reduce emissions.
The most common offsets generated and sold into compliance and voluntary markets are those
from forestry projects. These projects protect forests and sequester carbon through improved
forest management, avoided conversion, or afforestation. Offset sales provide landowners an
economic incentive to implement best forest management practices, avoid conversion of forest
lands, or allow reforestation of trees, instead of cutting them down to sell lumber or develop
the land for other revenue streams like commercial/residential real estate or agriculture use.
It’s estimated that over $1 billion has been paid to U.S woodland owners7 not to cut forests.
While forests sequester carbon, dairy digesters capture methane instead of allowing it to
release into the atmosphere. Most dairy farms store manure in a lagoon; creating an anaerobic
environment in which the manure produces methane that is released into the atmosphere as it
breaks down. Over an extended period of time, methane can be about 85 times more potent
compared to carbon dioxide. Capturing and putting the methane to productive use, such as
generating electricity, prevents that methane from entering the atmosphere. Since the dairy
farmer built a system above and beyond what is required to manage the manure, a carbon
offset is produced and can be sold to recoup some of the farmer’s investment.
Similar to dairy digesters, offsets may be generated by methane capture at coal mines. To
operate a coal mine safely, methane must be drained from the coal seam. Voluntarily capturing
the methane that would otherwise emit to the atmosphere and putting it to a beneficial use
such as electricity generation creates an offset, and therefore, revenue to recoup some of that
investment.
“Additionality” is a key feature of all offsets, meaning actions taken to reduce emissions must
be done on a voluntary basis without any requirement by federal, state, or local laws or
regulations. Furthermore, offset projects must demonstrate that the project activity is not
business-as-usual and that reductions would not have happened without the revenue from
offset sales. Forestry, dairy digesters, and coal mine capture projects are three of the six project
types approved by the California Air Resources Board and included in Palo Alto’s Carbon
Neutral Gas Plan. Attachment B contains visual representations of coal mine methane capture
and dairy digester projects. Attachment C provides detail on all six project types.
Offset Concerns

City of Palo Alto Page 4
Carbon offset markets gained momentum in 2005 as a result of the Kyoto Protocol which
established the Clean Development Mechanism (CDM) as the method to measure and verify
emission benefits. Over time, research highlighted flaws with CDM-issued offsets that involve
the lack of robust additionality tests, poor accounting possibly resulting in double counting,
inaccurate savings estimation, leakage (an increase in emissions in one location resulting from a
decrease in another location), and permanence. Environmental activists and concerned citizens
have criticized carbon offsets by questioning whether these projects would occur without the
offset market and uncovered inaccuracies in actual emission reductions. Further, not enough
offsets can be created to meet the total emission reduction targets needed to address global
warming concerns. Finally, purchasing offsets enables buyers to continue creating emissions. All
of these are points to be cognizant of when evaluating the role of carbon offsets as a climate
action strategy.
Mitigation of Offset Concerns
While there is inherent uncertainty involved in estimating emission reductions that result from
carbon offset projects, there are many ways these concerns have been addressed in today’s
offset market, including offsets developed for California’s Cap and Trade Program. The City
does have a compliance obligation under California’s Cap and Trade program; the regulations
limit the use of offsets to 8% of capped emissions. The City’s Carbon Neutral Gas Plan is
separate and distinct from the City’s Cap and Trade obligations. Under California’s Cap and
Trade Program, CARB established protocols8 for six project types.
1. U.S. Forest Projects
2. Urban Forest Projects
3. Livestock Projects
4. Ozone Depleting Substances Projects
5. Mine Methane Capture projects
6. Rice Cultivation Projects
CARB adopted these protocols and approved carbon offset registries via a rigorous rulemaking
process detailed in CARB’s Process for the Review and Approval of Compliance Offset Protocols9
CARB developed each of these protocols to create real, additional, verifiable, and permanent
emission reductions10. Though there are periodic studies that critique or recommend
improvements, CARB’s protocols have addressed many of the earlier issues or critiques with
carbon offsets which originated from the Clean Development Mechanism. Offsets purchased

under Palo Alto’s Carbon Neutral Gas Plan are restricted to projects that are tracked by CARB
approved registries and comply with CARB protocols. Attachment C contains detailed
descriptions of each of the project types and the protocols. CARB protocols have strict
additionality requirements, thorough verification processes, detailed monitoring and reporting
to demonstrate permanence.
Offsets can be part of a bridging strategy while technologies and policies evolve to accelerate
the ability to directly reduce emissions in a cost-effective manner.
Potential to use Carbon Offsets for Other City Emissions
Carbon offsets can and have been used by cities, corporations and individuals to mitigate
emissions from sources beyond those resulting from burning natural gas. This report only
addresses carbon offset use in the context of the Carbon Neutral Gas Plan and does not
contemplate an expanded role to achieve the other City sustainability goals.
Carbon Neutral Gas Plan Overview to Date
Since July 2017, emissions resulting from customers burning natural gas has been mitigated
100% by carbon offset purchases equal to CPAU’s natural gas sales. When the plan was
established four years ago, staff limited the purchases of offsets to project types accepted by
CARB-approved California Cap and Trade compliance protocols. Council approved five enabling
agreements with brokers that sell carbon offsets. The standard form agreement was approved
via staff report 871711 (Reso 970312), and the five enabling agreements were approved via staff
report 8717, (Reso 970413), staff report 941814 (Reso 978715), staff report 979316 (Reso 979317),
and staff report 970018, (Reso 979819). Staff executes approximately two transactions per year
to buy offsets. A maximum rate impact of up to 10¢/therm ($19/ton CO2e) was approved, and
to date the cost of offsets has averaged less than 3¢/therm ($6.25/ton CO2e). The figure below
illustrates the project types represented in the offset purchases to date.

Offsets used for Cap and Trade compliance must go through one final certification step by
CARB. CARB-certified offsets may not be used for Palo Alto’s Carbon Neutral Gas Plan, however,
the offsets the City purchases adhere to the same CARB protocols as do those that are sold in
the compliance offset pool. Council also approved a purchase for about 10% of FY 2019 carbon
offset needs from a forestry project near Palo Alto’s sister city, Oaxaca, Mexico (staff report
856420, Reso 972521) utilizing a protocol nearly identical to that applied to U.S. forestry projects.
While the plan includes a preference for local and California located projects, there is no
Council-approved premium for California projects. To date, none of the offset projects have
originated in California. Attachment D shows details of all carbon offset transactions thus far.
There are two potential opportunities for local projects. Palo Alto administers a refrigerator
recycling program and may purchase offsets resulting from the destruction of the related ozone
depleting substances. Pricing has not been determined, and the quantities represent less than
1% of Palo Alto’s offset needs. The second local project could be Urban Forestry which staff is
exploring.
Review of Carbon Neutral Gas Plan Parameters
Spot Purchases versus Investing in Projects
There are two ways to procure offsets. The first is to purchase offsets on the “spot market”.
These offsets have already been created, verified, are ready to be sold, and are tracked by
CARB approved registries. The other is to invest in projects that will generate offsets in the
future. For example, an organization might provide capital to a dairy farmer so that the dairy
farmer can build a digester. The investor receives offsets over a period of time once the
digester is operational. This is similar to investing in a power plant and receiving energy over a
period of time.

City of Palo Alto Page 7
The Carbon Neutral Gas Plan is currently restricted to spot purchases. Because the plan is a
bridge to electrification, and therefore a shorter-term strategy, and because project investment
inherently carries more risk, staff recommends continuing to limit transactions to spot
purchases.
Approved Project Types and Vintages
The plan currently restricts the purchase of offsets to project types that adhere to CARB
protocols. These include U.S. forest, urban forest, livestock, ozone depleting substances, mine
methane capture, and rice cultivation projects. CARB allows offsets generated in 2006 or later.
Staff has reviewed the CARB protocols and is satisfied that CARB’s requirements and standards
ensure projects are real, additional, accurate, and verifiable. Staff recommends continuing
restricting offsets to project types which adhere to CARB protocols. In addition, staff
recommends mirroring CARB’s vintage requirements for offset purchases for the Carbon
Neutral Gas Plan in the future. This means that projects must have been completed in 2006 or
later.
CARB currently does not have a protocol for forestry projects outside of the U.S. Should
another opportunity arise like the 2017 purchase from the forestry project in Oaxaca, staff will
follow the same process by bringing it to Council for consideration.
Approved Prices for Offset Transactions
The Carbon Neutral Gas Plan includes an overall rate impact cap of up to 10¢/therm,
approximately $19/ton CO2e. To provide clarity for Plan implementation, staff recommends
that no single transaction will exceed $19 per ton CO2e.
Basis for Offset Quantities Purchased
Offsets are purchased in quantities that match CPAU’s natural gas sales. The Plan covers natural
gas sales and explicitly excludes any local distribution losses or other upstream emissions. Staff
intends to cover this topic as part of a broader S/CAP discussion.
Resource Impact
There is no new resource impact expected from the adoption of this resolution.
Policy Implications
The Carbon Neutral Gas Plan is consistent with the Council-adopted 2018-2020 Sustainability
Implementation Plan22 which included a goal to mitigate the impacts of natural gas use through
carbon offsets and key actions including purchasing carbon offsets to mitigate natural gas
emissions.

Next Steps
If the Carbon Neutral Gas Plan modifications are approved by Council, staff will implement the
changes immediately, beginning with offset purchases for the second half of FY20.
Stakeholder Engagement
On October 7, 2020, the UAC considered a proposed update to the Carbon Neutral Gas Plan. In
an effort to address Council’s previously stated preference for California carbon offsets, staff
recommended an authorized 10% premium to paid for in-state carbon offsets. Citing the lack of
sustainability advantage from a project in California versus somewhere else and the current
economic environment, the UAC did not support the premium. Because California projects may
yield co-benefits such as jobs and cleaner air, all else being equal, staff will continue to favor in-
state carbon offsets. The proposed Carbon Neutral Gas Plan, as shown in Attachment A, Exhibit
A, was modified to reflect this change. At the UAC request, staff also reworded the objective of
the Plan to clarify the intent is to mitigate GHG emissions from natural gas usage in the City as a
bridging strategy toward absolute reductions in natural gas use.
With the two changes described above, the UAC voted unanimously to recommend Council
approval of the amended Carbon Neutral Gas Plan.
Environmental Review
The Council’s adoption of a resolution modifying the Carbon Neutral Gas Plan does not meet
the definition of a project, pursuant to section 21065 of the California Environmental Quality
Act (CEQA). Offset project developers are responsible for performing necessary environmental
reviews and acquiring permits as offset projects are developed.

Resolution of the Council of the City of Palo Alto
Amending the Carbon Neutral Natural Gas Plan to
Continue to Achieve Carbon Neutrality for the City’s
Natural Gas Supply Portfolio
R E C I T A L S
A. In December 2007, Council adopted the City’s Climate Protection Plan which set
aggressive greenhouse gas (GHG) emission reduction goals to be achieved by the year 2020.
B. In March 2013, Council approved Resolution 9322 directing staff to achieve carbon
neutrality for the electric supply portfolio by 2013 through the use of a combination of
hydroelectric resources, long-term renewable resources and short-term renewable energy
resources and/or renewable energy certificates (“RECs”).
C. On September 9, 2013, Council approved Resolution 9372 modifying and
suspending portions of the PaloAltoGreen Program and directed staff to develop a
PaloAltoGreen Gas (PAG Gas Program) Program.
D. On April 21, 2014, Council approved Resolution 9405 establishing the voluntary
PAG Gas Program to provide the opportunity for residential and commercial customers to
economically reduce or eliminate the impact of GHG emissions associated with their gas usage
through the purchase of certified environmental offsets.
E. In April 2016, Council adopted a GHG reduction goal of 80% by the year 2030. GHG
emissions associated with natural gas used by City of Palo Alto Utilities customers were 135,000
metric tons of carbon dioxide equivalent, or 27% of the City’s GHG emissions, in 2015.
F. Staff initially proposed a Carbon Neutral Natural Gas Plan that would use a
combination of physical biogas and high-quality environmental offsets to achieve a carbon-
neutral gas portfolio by fiscal year 2018 by maximizing the amount of biogas in the portfolio
while holding the rate impact at a maximum limit of ten cents per therm (10 ₵/therm).
G. On August 31, 2016, the Utilities Advisory Commission voted 6-1 to recommend
Council approve a Carbon Neutral Gas Plan using a combination of physical biogas and high-
quality environmental offsets to achieve a carbon-neutral gas portfolio and direct staff terminate
the PAG Gas Program.
H. On October 18, 2016, the Finance Committee voted 2-1 to instead recommend
that Council:
I.
(i) Adopt a resolution that (a) approves a Carbon Neutral Natural Gas Plan that would
----
Attachment A

enable the City to achieve a carbon-neutral gas supply portfolio starting in Fiscal Year (FY) 2018
with a rate impact not to exceed ten cents per therm (10 ¢/therm); and (b) terminate the PAG
Gas Program established by Resolution 9405; and
(ii) Direct staff to: (a) develop an implementation plan for the Carbon Neutral Natural
Gas Plan; (b) provide an option for Council to consider prioritizing local offsets; and (c)
prioritize maximizing carbon reduction within the 10 ₵/therm rate impact cap.
J. On December 5, 2016, Council adopted Resolution 9649 approving a carbon
neutral gas plan starting in fiscal year 2018 with a rate impact not to exceed ten cents per
therm (10 ₵/therm) and terminated the PAG Gas program established by Resolution 9405.
K. On October 7, 2020, the Utilities Advisory Commission voted 7-0 to recommend
Council approve the amended Carbon Neutral Gas Plan as outlined in Exhibit A.
The Council of the City of Palo Alto RESOLVES as follows:
SECTION 1. The Council hereby adopts a resolution:
1. Approving an amended Carbon Neutral Natural Gas Plan, as shown in Exhibit
A, enabling the City to maintain a carbon-neutral gas supply portfolio.
//
//
//
//
//
//
//
Attachment A
**Not Yet Approved**
6055443
//
//
SECTION 2. The Council’s adoption of this Resolution, which amends the Carbon
Neutral Natural Gas Plan, does not meet the definition of a project, pursuant to section 21065
of the California Environmental Quality Act (CEQA). Offset project developers will be
responsible for acquiring necessary environmental reviews and permits as those projects are
developed.

CITY OF PALO ALTO CARBON NEUTRAL GAS PLAN
EXHIBIT A TO RESOLUTION NO.______
ADOPTED BY COUNCIL ON: _______
RECOMMENDED FOR APPROVAL BY UTILITIES ADVISORY COMMISSION ON: Oct. 7, 2020
Carbon Neutral Gas Plan Objective:
Originally adopted by the City Council on December 5, 20161, the objective of the City's Carbon
Neutral Gas Plan is to mitigate the GHG emissions resulting from natural gas use in the City of
Palo Alto through the purchase of high-quality carbon offsets as a bridging strategy toward
absolute reductions in natural gas use. Implementation of the Carbon Neutral Gas Plan will be
carried out by staff.
Carbon Neutral Gas Plan Elements:
1. The quantity of offsets purchased to meet the City’s Carbon Neutral Plan objectives will
be matched to carbon emissions associated with the City’s natural gas sales volume;
2. Offset purchases must be from project types which adhere to California Air Resource
Board (CARB)-approved cap and trade compliance protocols, currently including U.S.
Forest, U.S. Urban Forest, U.S. Livestock, U.S. Sourced and Destroyed Ozone Depleting
Substances, U.S Mine Methane Capture, and U.S. Rice Cultivation; or any other project
type subsequently approved by CARB;
3. Offset purchases are restricted to CARB’s vintage requirements, which currently permit
offsets generated in 2006 or later;
4. Offset transactions are limited to spot purchases, which are for offsets that have already
been created, verified, and are ready to be sold;
5. Rate impacts of individual offset transactions are limited to under $19 per ton of CO2e.
This is consistent with the Council-approved maximum rate impact of 10₵/therm.
6. In implementing the Carbon Neutral Gas Plan, staff will maintain a preference for
California projects as long as this preference does not result in a price premium.

ATTACHMENT C: California Air Resources Board Compliance Offset Protocols1
1. Livestock Projects: Capturing and Destroying Methane from Manure Management Systems
This protocol defines a set of activities designed to reduce GHG emissions that result from
anaerobic manure treatment at dairy cattle and swine farms. Projects that install a biogas control
system (BCS) that captures and destroys methane gas from anaerobic manure treatment and/or
storage facilities on livestock operations are eligible.
Project Definition:
(a) The BCS must destroy methane gas that would otherwise have been emitted to the
atmosphere in the absence of the offset project from uncontrolled anaerobic treatment
and/or storage of manure.
(b) Captured biogas can be destroyed on-site, transported for off-site use (e.g. through gas
distribution or transmission pipeline), or used to power vehicles.
(c) A centralized digester that integrates waste from more than one livestock operation
meets the definition of an offset project.
CARB Livestock Protocol2
2. Mine Methane Capture Projects: Capturing and Destroying Methane From U.S. Coal and
Trona Mines
This protocol includes four mine methane capture activities designed to reduce GHG emissions
that result from the mining process at active underground mines, active surface mines, and
abandoned underground mines.
The following types of mine methane capture activities are eligible:
(a) Active Underground Mine Ventilation Air Methane Activities are projects that install
a ventilation air methane (VAM) collection system and qualifying device to destroy
the methane in ventilation air otherwise vented into the atmosphere through the
return air shaft(s) as a result of underground coal or trona (sodium carbonate
compound used to make baking soda) mining operations.
(b) Active Underground Mine Methane Drainage Activities are projects that install
equipment to capture and destroy methane extracted through a methane drainage
system that would otherwise be vented into the atmosphere as a result of
underground coal or trona mining operations.
(c) Active Surface Mine Methane Drainage Activities are projects that install equipment
to capture and destroy methane extracted through a methane drainage system that
would otherwise be vented into the atmosphere as a result of surface coal or trona
mining operations.

(d) Abandoned Underground Mine Methane Recovery Activities are projects that install
equipment to capture and destroy methane extracted through a methane drainage
system that would otherwise be vented into the atmosphere as a result of previous
underground coal mining operations.
CARB Mine Methane Capture Protocol3
3. Ozone Depleting Substances Projects: Destruction of U.S. Ozone Depleting Substances Banks
This protocol defines a set of activities designed to reduce GHG emissions by the destruction of
eligible Ozone Depleting Substances (ODS) at a single qualifying destruction facility.
ODS destroyed under this protocol must be from one or more of the eligible sources listed below:
(a) Refrigerants from industrial, commercial or residential equipment, systems, and
appliances or stockpiles;
(b) ODS blowing agents extracted and concentrated from appliance foams; or
(c) Intact foam sourced from building insulation.
CARB Ozone Depleting Substances Protocol4
4. Rice Cultivation Projects
This protocol includes three rice cultivation project activities designed to reduce GHG emissions
that result from rice cultivation on fields in the California and Mid-South Rice Growing Regions.
The following types of rice cultivation activities are eligible:
(a) Dry Seeding Activities are projects that sow seeds into a dry or moist, but not flooded,
seedbed by drilling or broadcasting seeds onto rice fields, resulting in the reduction of
methane that would otherwise be released into the atmosphere if the seeds were wet-
seeded.
(b) Early Drainage in Preparation for Harvest Activities are projects that drain or dry standing
water, while the soil is still saturated, from rice fields earlier during the rice growing
season in preparation for harvest, resulting in the reduction of methane that would
otherwise be released into the atmosphere if the rice fields were drained or dried on the
customary date.
(c) Alternate Wetting and Drying Activities are projects that cyclically wet and dry the rice
fields during the growing season to reduce methane emissions that would otherwise be
released into the atmosphere if the project employed continuous flooding.

5 https://ww2.arb.ca.gov/sites/default/files/classic/cc/capandtrade/protocols/rice/riceprotocol2015.pdf
5. U.S. Forest Projects: Sequestered Carbon on Forestland.
The protocol provides offset project eligibility rules; methods to calculate an offset project’s net
effects on greenhouse gas (GHG) emissions and removals of CO2 from the atmosphere
(removals); procedures for assessing the risk that carbon sequestered by a project may be
reversed (i.e. released back to the atmosphere); and approaches for long-term project
monitoring and reporting. The protocol is designed to ensure that the net GHG reductions and
GHG removal enhancements caused by an offset project are accounted for in a complete,
consistent, transparent, accurate, and conservative manner and may therefore be reported as
the basis for issuing ARB or registry offset credits.
U.S. Forest Projects include reforestation, conversion avoidance and forest management.
Forest management practices may include increasing time between harvest, increasing
productivity by thinning diseased and suppressed trees, increasing productivity by managing
brush and short-lived forest species, and planting more trees.

6. Urban Forest Projects: Sequestered Carbon in Urban Canopy
This protocol applies to a planned set of urban tree planting and maintenance activities that
permanently increase carbon storage, taking into account GHG emissions associated with
planting and maintenance of project trees. Only offset projects located in the United States and
its territories are eligible under this protocol.

Project Protocol Description
Grotegut Dairy Livestock Grotegut Dairy is a 3,900 milk-cow operation in Newton, Wisconsin with a methane capture system.
Green Trees U.S. Forest
GreenTrees Advanced Carbon Restored Ecosystem is reforestation of agricultural lands into native
hardwood forest in Mississippi, Louisiana, Arkansas, and Illinois
San Juan Lachao Mexican Forest
Protection of forests located in High Biological Value Zones which contain flora and fauna listed in the
Mexican Endangered Species List and the International Union for Conservation of Nature’s Red List of
Threatened Species. Project in San Juan Lachao near Palo Alto's Sister City of Oaxaca.
Blandin Forest U.S. Forest Blandin Native American Hardwoods Conservation and Carbon Sequestration project in Minnesota.
Pocosin+ U.S. Forest
These projects are all forested land that will not be disturbed by human development. Without this
protection, the forests would be converted to grow wheat or corn. Forest conservation plays a vital
role in protecting freshwater systems like lakes. The forests around the lakes act as natural water
filters and purify the water for all who use it. The projects also support healthy populations of red
wolf, bald eagle, black bear, and various bird species.
Refex ODS Ozone Depleting Substance
The RemTec facility in Bowling Green, Ohio uses an argon arc plasma destruction device to achieve
99.99 percent removal. The majority of refrigerants originated in California, and all were sourced
within the United States.
The RemTec facility uses an argon arc plasma destruction device to achieve the required destruction
and removal efficiency of 99.99 percent. The majority of ODS refrigerants originated in California, and
all were sourced within the United States.
Methane Capture Mine Methane Capture
This project is the first of its kind. Peabody Natural Gas, LLC removed methane from the North
Antelope Rochelle Coal Mine before mining. The methane was compressed and transported to a
natural gas pipeline and distributed to a national gas grid for use as fuel. Before implementation of
the project, all the methane was vented to the atmosphere.
