Climate Action and Adaption Plan

Climate Action and Adaptation Plan Overview:

Monterey One Water (M1W) is committed to providing safe, resilient water solutions that include the reduction of greenhouse gas (GHG) emissions and enhancing the community resilience towards vulnerabilities and risks posed by climate change. The goal of M1W’s Climate Action and Adaptation Plan (CAAP) is to develop policies, programs, and measures to reduce reliance on fossil fuels with co-benefits of decreased air emissions, providing long term cost savings, and building resiliency into M1W facilities and operations during climate change induced, sea level rise, flooding, extreme heat events, wildfires and other risks. By using energy more efficiently, harnessing renewable energy to power M1W facilities, recycling solid waste, and enhancing access to sustainable transportation modes, M1W will keep dollars in the local economy, create jobs, and improve the community’s quality of life. This CAAP provides a comprehensive roadmap for M1W to address the challenges of climate change. Through this CAAP, M1W has established goals and policies that incorporate environmental responsibility into the everyday management of its operations. The CAAP also presents a climate change vulnerability analysis and adaptation strategies to address potential impacts of climate change.

Greenhouse Gas Emissions Inventory

The first step in developing the CAAP was to prepare M1W’s baseline GHG emissions inventory. The GHG inventory was prepared for the years 2019 and 2020, which represents the years for which the most recent data was available. However, because of the COVID-19 pandemic occurring in 2020, the inventory for 2019 may be more representative of typical operations. M1W emitted approximately 3,102 metric tons carbon dioxide equivalent (MMT CO2e) in 2019. The largest portion of M1W’s 2019 emissions were from natural gas (69.34 percent), followed by emissions from wastewater treatment processes and flaring (26.81 percent) and electricity (2.20 percent). Figure 1 shows a sector level GHG emissions inventory results for the 2019.

Greenhouse Gas Emissions Forecasting, Target Setting, and Reduction Measures

M1W’s future emissions were estimated using demographic indicators such as population, households, and jobs growth within the service area. Table A shows growth indicators. These growth factors were used to more accurately predict the year 2030 and 2045 emission forecasts. 

Growth Indicators for 2020, 2030, and 2045

Future emissions estimates also include reductions that would occur with implementation of legislation adopted at the State level. That is, some level of emission reduction is anticipated within M1W as a result of policies implemented at the State level, including:

  • Low Carbon Fuel Standards
  • Assembly Bill (AB) 1493 and Advanced Clean Cars
  • Renewable Portfolio Standard

The resulting projected emissions are considered an “adjusted” business-as-usual (ABAU) forecast. Figure 2 shows historic emissions and ABAU forecasts. Consistent with the State’s adopted AB 32 and SB 32 GHG reduction target, M1W has set a goal to reduce emissions 40 percent below 2020 levels by 2030. These reduction targets would put M1W on a path toward the State’s long-term goal to achieve statewide carbon neutrality (zero net emissions) by 2045. See Table 1.

GHG Reduction Targets for Monterey One Water Emissions

M1W has demonstrated its commitment to conserve energy and reduce emissions through a variety of plans and policies. In order to reach the reduction target, M1W would implement reduction measures shown in Table 2. These measures encourage energy efficiency, water conservation, on-road transportation reductions, solid waste and biosolid reduction, natural gas, and off-road source emissions. 

Summary of GHG Reduction Strategies and Emission Reductions

Climate Change Vulnerabilities, Adaptation, and Resiliency Goals

M1W recognizes that planning sustainably is more than reducing GHG emissions; it also requires being prepared for changes that would impact the local quality of life, its use of resources, and the local economy. Preparedness, or adaptation, efforts seek to reduce vulnerability and increase the local capacity to adapt to changes. The analysis in the CAAP is predicting increased temperatures, variable precipitation and increased extreme weather events, increased intensity of wildfires, and sea level rise in the years to come. M1W has developed adaptation strategies to reduce potential impacts and build resiliency in its facilities, assets, and serviced communities. The adaptation strategies focus on fortifying and/or relocating pump stations, pipelines, and other assets vulnerable to flooding and sea level rise.  M1W is also focused on reliable power supplies to the facilities and assets to provide continuous operations during wildfires and extreme weather events.
