Climate Change and
The California
Public Utilities Commission’s Role
Climate
Change Implications
Concentrations
of greenhouse gases[1] (GHGs) have
increased sharply in the atmosphere from pre-industrial levels. Human activities are largely
responsible for much of this build-up. The
concentrations of these gases have increased approximately 30% above
pre-industrial concentrations. Most
of the observed warming over the past 50 years is likely due to the increase in
greenhouse gas concentrations. The primary activities that have resulted in the increasing
amounts are from burning fossil fuels for energy production, manufacturing, and
transportation. One of the significant results attributed to these emissions is
an increase of the earth’s average temperatures and the changing of weather
patterns over time. The increase in average and peak surface temperatures
threatens to disrupt the natural functioning of the planet that provides the
basis for all human activities, including the global economy and California’s
participation in it.
The
scientific community widely acknowledges the issue of climate change and there
is growing consensus about its potential effects. While the timing and
magnitude of exact effects remain uncertain, reports and studies modeling the
environmental impacts indicate that the changes will likely be significant and
that temperature and weather pattern changes have, in fact, already begun. Effects
on rainfall and temperature will, in turn, affect energy supply and demand,
water availability, agricultural production, population migration, and the
economy.
Several
studies have published recently specifically focus on climate change impacts in
California. One of the most recent
studies published in the Proceedings of the National Academy of Sciences and
conducted by several universities and research institutions specifically
profiled projected average temperature, snowpack, and reservoir changes.[2] The study modeled two scenarios. The first assumed fossil fuel use
continues at its present pace. The
second modeled significant increases in the use of renewable energy. Although temperature change in the
latter scenario was not as alarming as in the first, the study still concluded
that the remaining fossil fuel emissions could push average high temperatures
up by four to six degrees by 2070, with increases in incidents of heat waves and reductions in
snowpack and rainfall.
The
social and economic impacts are significant. Worldwide, natural disasters in the first 10 months of 2004
cost the insurance industry more than $35 billion, up from $16 billion in 2003,
not to mention the devastating effects on human lives and local economies.[3]
Further, the U.N. Environment Program anticipates an increase in the frequency
and intensity of extreme weather events.
Swiss Re and other insurance companies have acknowledged that climate
change will continue to have an impact on the insurance industry.
The
United States is the world’s largest emitter of greenhouse gas emissions (GHG),
accounting for roughly 25 percent of global emissions, but accounts for under 5
percent of the world’s population.
The federal EPA estimates that electricity generation, transportation,
and industrial activities collectively contribute 80 percent of emissions.
Climate
change has been studied extensively for more than thirty years. In the face of clear and overwhelming
scientific evidence, the time has come for California to act.
California’s
Contribution
California,
home to 36 million people, is the nation’s largest consumer of residential,
commercial, and transportation energy, and is second only to Texas in
industrial energy use. California
also has the largest and most diverse economy of any state, including the
biggest agricultural economy. When
compared to global economies, California ranks sixth.
The
state’s sheer size presents significant regional, national, and global
implications. In 2000, California
emitted approximately 420 million metric tons of carbon dioxide equivalents
from energy related sources[4]. In comparison, the state of Washington
emitted 94 million tons, and Oregon emitted 61 million tons. When examining at the numbers, one
cannot help but recognize that our energy-related GHG contributions represent a
significant proportion of overall West Coast and United States contributions.
Based
upon current projections, California’s emissions growth rate will outpace that of
our neighbors by 1.6% per year. The major contributors of greenhouse gases are
transportation (nearly 50%) and electricity consumption (25-30%). Residential, industrial, commercial,
agricultural, and non-energy related sources each contribute the remaining 25
percent.
The
implications of climate change on California’s economy are significant. Not
only does the state rely on existing weather patterns for annual rainfall and
snowpack conditions, it relies on these patterns to ensure the viability of the
state’s businesses, economy, and resources. Impacts on availability of water resources and energy
demands due to increasing average and peak temperatures and shortened growing
seasons could threaten the industries that California relies upon to drive and
sustain the California economy. The implications on vital resources are
projected to be significant by 2070[5].
Examples
include:
Moving
Toward Solutions: Policy Options and Voluntary Business Actions
In
the United States, climate change is currently an issue most aggressively
addressed at the local, state, and regional levels. While close to two hundred countries have endorsed an
international effort to address climate change globally, the Bush Administration
has chosen not to ratify the Kyoto Protocol treaty. With Russia’s ratification in November 2004, the Protocol
will go into effect on February 16, 2005. Between 2008 and 2012, the 38 signatory
industrialized countries have committed to cut their greenhouse gas emissions
to levels that average 5.2 per cent below 1990 levels. In addition, the
emissions trading regimes and other market mechanisms established under the
Protocol have begun implementation.
Countries that do not ratify the Protocol will be barred from
participating in these market-based mechanisms, and may also be barred from
parallel national and multi-national trading regimes of parties to the
Protocol.[6] At this point, it is unclear whether
the terms of the Protocol will be expanded to allow for individual states, such
as California, to participate in the Protocol and its related programs.
Despite
the uncertainty and delay of U.S. participation, many businesses are taking
steps to mitigate their emissions. Legislators in the U.S. have proposed bills
that would define and regulate GHGs, and lawsuits have been filed against the
EPA by environmental organizations and states for failing to address climate
change and pollution requirements and classifications. In 2004, California and seven other
states filed a lawsuit against the nation’s five largest utility companies
demanding that they reduce their emissions[7]. In addition, the California Air
Resources Board (CARB) recently unanimously approved groundbreaking and highly
effective rules to reduce GHG emissions from automobiles. Under the CARB proposed regulations,
the auto industry must cut GHG emissions from cars and light trucks beginning
with 2009 models. Compliance with
the new regulation is estimated to reduce greenhouse gas emissions from light
duty passenger vehicles by 18% in 2020 and 27% in 2030.[8]
Current
climate change policy-related efforts in California include the West Coast
Governors’ Global Warming Initiative efforts[9]
and research on impacts and strategies[10],
the Climate Action Registry’s[11]
voluntary emissions tracking program established by the state legislature, the
California Climate Change Advisory Committee,[12]
and the joint energy agencies’ Energy Action Plan.[13] In addition, many working groups are in
place to collectively address the issue and share information and resources.
Recently,
several studies analyzed the impacts of climate change in California and have
provided similar recommendations on how best to address the issue. The Tellus
Institute’s findings on behalf of the West Coast Governors’ Global Warming
Initiative[14], the Pew
Center on Global Climate Change, The Union of Concerned Scientists, The
Columbia Journal of Environmental Law, and other research all recommend similar
actions to reduce emissions including:
·
Tracking and reporting of greenhouse gas emissions
·
Improved energy efficiency and conservation efforts
·
Improved vehicle efficiency and alternative transportation systems
·
Updated building and appliance efficiency standards
·
Increased power plant efficiency
·
Increased renewable energy generation
·
Implementation of an electricity sector GHG policy
It
is clear that the California Public Utilities Commission (CPUC) has the
opportunity to direct or influence each of the above recommendations as they
relate to the CPUC’s regulated utilities’ activities. Whether through continued and improved energy efficiency and
renewable portfolio standard efforts, the encouragement of regulated entities
to accelerate deployment of cleaner fleet vehicles, efforts to inform the public,
or the accurate reporting of GHG emissions, CPUC policy influences the behavior
of the regulated industries including the offer and delivery of products and
services.
We
have the opportunity to reduce greenhouse gas emissions, and to accelerate development
and adoption of new clean technologies. Innovative solutions to address the
issue of climate change can be fostered by CPUC policies and actions taken by
regulated utilities. This effort
is necessary to ensure that California businesses continue to participate proactively
and effectively in the regional, national, and international economies.
Businesses
and their shareholders worldwide are beginning to address global warming and to
identify policies and actions necessary to facilitate mitigation. Many businesses anticipate that
mandatory reductions or limits will eventually be put in place, and GHG emissions
trading programs are likely to be developed. Businesses can best comply with future limits and rules if
there is both consistency and coordination among states and countries. What businesses – and the economy –don’t
tolerate well is uncertainty and unnecessary risk.
Swiss
Re, an insurance giant, says the word is getting out about financial risk
associated with GHG emissions, but not fast enough. In a recent survey, “80% of CEOs said that climate change
was a potential risk, but only 40% were doing something about it. That’s not good to hear for insurers.[15]” Further, the Columbia Journal of
Environmental Law concludes that “the issue of climate change has the potential
to affect significantly the well-being of corporations involved in a wide
variety of business sectors.
Counsel to such corporations should educate themselves to both the risks
and the opportunities that this issue presents to their particular companies
and advise their clients accordingly.[16] They identify potential for litigation,
directors’ and officers’ liabilities, shareholder initiatives, and disclosure
obligations as potential external drivers for companies to address the issue of
climate change.
The
California State Controllers Office has begun to look at the issue of financial
risk associated with energy use and GHG emissions and is working with the
financial community to encourage companies to adopt sustainable business
practices. Investors of all sizes
are calling for environmental disclosure from businesses, and shareholder
resolutions on the issue are increasingly being proposed. Development and use of sustainable
business practices are becoming recognized as central to the longevity of a
firm’s core business.
The
business case for addressing climate change is becoming more evident. Business for Social Responsibility
(BSR), a non-profit think-tank, has developed working papers on climate change[17]
and energy efficiency. They cite
many success stories of companies as large as Alcoa and Dupont that have
implemented significant efforts to mitigate their emissions contributions. BSR offers the following implementation
steps to companies interested in reducing their energy consumption and
pollution: 1) Improve energy efficiency, 2) Limit Transportation, 3) Purchase
Renewable Energy, 4) Trade Emissions, 5) Offset Carbon Emissions, 6) Measure
and Report GHG Emissions. In
addition, BSR provides general guidelines to help companies create a corporate
climate action plan.
Perhaps
most importantly, BSR’s research indicates that many companies who incorporate
climate change mitigation efforts into their company’s guidelines find that
they can save money, increase revenues, enhance their brand, and boost
productivity. They identify the
following real and tangible benefits to companies that have effectively
addressed climate change:
-
Reduced operating costs -
Improved productivity and quality
-
Increased market share -
Enhanced brand
-
New revenue sources -
Mitigation of future regulatory impacts
-
Improved cost-to-growth ratios
Further,
many experts believe that the majority of technologies needed to address
climate change are already in existence.
While there is no doubt that additional research and technologies are needed,
and programs and technologies need to be improved and developed, “humanity can
solve the carbon and climate problem in the first half of this century simply
by scaling up what we already know how to do.”[18] By developing a proactive and coherent
set of programs and policies to address greenhouse gas emissions, California
not only has the opportunity to mitigate climate change, but it also has the
opportunity to develop and implement climate-friendly business practices and
technologies. Global warming is
being discussed and addressed worldwide.
By taking a leadership position on the issue, California can influence,
incubate, and benefit from products, services, and business models that will lead
the way to the next phase of the industrial age.
The
CPUC’s Role
The
CPUC recognizes the importance of taking steps now to reduce GHG emissions. We
have the opportunity to make a significant contribution to emissions reductions
statewide and nationally and to demonstrate responsible participation within
the economy. By taking a leadership role and significantly reducing GHG
emissions, we can encourage acceleration of similar actions across the
U.S.
The
CPUC has recently undertaken efforts to identify and address GHG emissions
associated with regulated energy utilities. Our initial activities included the adoption of the Energy
Action Plan in May 2003. The
Energy Action Plan articulates the joint commitment of this Commission and the
California Energy Commission (CEC) to energy resource planning that reflects
“continuing progress in meeting the state’s environmental goals and standards,
including minimizing the energy sector’s impact on climate change.” More specifically, the Energy Action
Plan recognizes the need to “encourage companies that invest in energy
conservation and resource efficiency to register with the state’s voluntary
Climate Action Registry.”
The
four largest California energy utilities (Southern California Edison Company,
Pacific Gas and Electric Company, Southern California Gas Company, and San
Diego Gas and Electric Company) are members and active participants in the
California Climate Action Registry, and are currently measuring and developing
inventories of their GHG emissions. The CPUC is also a member, and we are in
the process of inventorying our own GHG emissions. The two most important steps initially taken are: first, to
build a complete and accurate inventory of emissions and, second, to develop a
plan to reduce or mitigate those sources of emissions.
In
June 2004, the CPUC requested that its regulated energy utilities address key
issues pertaining to climate change as part of their long-term energy
procurement planning. This includes internal planning and measurement of GHGs,
an assessment of the utilities’ current GHG emissions profile, and any steps
the utilities have taken to minimize the release of these gases. Building on
this information and on the substantial input from interested stakeholders, the
Commission took two significant steps, when it adopted its most recent
Procurement Order[19],
in December 2004:
·
Greenhouse Gas Adder: The IOUs are now required to employ a
“greenhouse gas adder” when evaluating competitive bids to supply energy. This
adder is designed to capture the financial risk to IOU ratepayers of emitting
GHGs, recognizing the likelihood that these emissions will be limited by
regulation in the future. The adder will improve the cost-effectiveness of
energy efficiency and renewable generation resources.
·
Incentives Framework: The Commission is now investigating, as part
of a general framework of incentives to promote the selection of
environmentally sensitive energy resources, the creation of a “carbon cap” to
be applied to each IOU’s resource portfolio.
We
are now turning our attention to other CPUC regulated industries (water,
telecommunications, and transportation), and anticipate that we will undertake
efforts with all regulated industries similar to those of the energy sector. We
have begun by encouraging all of our regulated industries to participate in the
Climate Registry and to initiate the process of benchmarking their GHG-related
activities.
We
recognize our direct role related to energy utilities and their supply-side
contributions and demand-side reductions.
In addition, many of the actions highlighted in the West Coast
Governors’ Report in the areas of building, industrial and electricity supply
strategies apply to all of the utilities we regulate. Much of this work has only just begun, and we would be
well-served by identifying and implementing additional efforts to significantly
reduce emissions in California.
We
also recognize the importance of targeting transportation strategies, since the
transportation sector is the most significant contributor of GHG emissions in
California. While our role here is
not quite as direct, it is imperative that we identify opportunities to
accelerate adoption of low emissions vehicle standards by regulated
transportation companies and all other regulated utilities utilizing fleet
vehicles.
In
addition, we will continue our collaborative efforts with other state agencies
including the California Energy Commission, CAL EPA, and the California Air
Resources Board to address this issue.
We will also pursue additional collaborative efforts to identify best
practices and to develop climate action policies, including the staff
recommendations developed by the West Coast Governors’ Global Warming
Initiative that were announced in November 2004.
The
CPUC is poised to play a key role in helping to reduce both the footprint and the
impact of GHG emissions on California’s economy and public health and to contribute
positively to the long-term growth of businesses operating in this state. Addressing climate change and
developing a climate action plan is simply an intelligent business decision. As
the international community moves forward to implement the Kyoto Protocol and
other efforts to reduce GHG emissions, California and its businesses have the
opportunity to lead with development and adoption of innovative technologies
and business solutions.
Recommended
Next Steps for the CPUC and IOUs
Regulated
Utilities’ Procurement and Operational Activities:
·
Establishment of Greenhouse Gas Emissions Baseline- Require all IOUs to
develop and maintain accurate baseline information for their GHG emissions
information that is verified by independent or third-party evaluators.
·
Emissions Reduction Plan- Require all IOUs to develop a GHG emissions
reduction plan that, at minimum, targets key sources of emissions.
·
Energy Procurement- Require energy utilities to use avoided cost
studies currently underway at the CPUC to determine procurement plans, quantify
operational and procurement costs, and to establish costs associated with their
current emissions levels- including quantification of existing economic
risk. Direct the IOUs to include a
requirement in their contracts with merchant generators that the generators
track their emissions according to CA Registry protocols, certify these
emissions according to CA Registry protocols, and make them publicly available.
·
General Operational Acquisitions- Require all IOUs and
transportation companies to incorporate consideration of climate change impacts
in all operational activities and supply chain procurement activities (similar
to CPUC diversity goals efforts).
·
Fleets- Working with other relevant state agencies, require early
adoption of low emission vehicles for all utilities’ fleets including light and
heavy-duty vehicles. Efforts
should include transportation and all other CPUC regulated entities. Recognize
economic value implicit in travel reduction efforts. Enhanced-efficiency-factor costing methodologies have been
developed and are one example of how a purchasing methodology can reduce
petroleum consumption and vehicle-related emissions of pollutants.
·
Cost Recovery- Adopt climate change-related policy
guidelines for business operations as well as procurement and acquisitions
activities. The CPUC should support reimbursement cost recovery where
appropriate.
Existing
Programs:
·
Renewable Energy Programs- Continue to accelerate and expand the
Renewable Portfolio Standard and renewable energy procurement, including
implementing requirements for Energy Service Providers. Identify and implement funding
sources and programs to meet the goals of the Governor’s Million Solar Roofs
Initiative.
·
Energy Efficiency- Expand cost-effective programs to meet
adopted energy savings goals and the Governor’s Green Building Initiatives. Support and participate in acceleration
of building and appliance codes and standards. Implement recommendations to
begin tracking GHG reductions associated with energy efficiency programs.
·
Demand Response- Broaden program efforts to increase
participation in demand response programs including time-of-use and critical
peak pricing programs to further reduce overall and peak energy demand.
·
Educational Information- Leverage existing utility ratepayer outreach
and education efforts that promote demand reduction and clean energy sources to
include information about climate change. (For instance, bill insert
information could include information about climate change and consumer actions
that can be taken to reduce their energy demand through energy efficiency, renewables,
demand response, and other programs, where appropriate).
·
Qualifying Facilities- Require QFs to track GHG emissions.
·
Coordination- The CPUC should work with other state
agencies and stakeholders to coordinate more effectively ratepayer programs related
to demand side reductions and clean energy.
Information
Sharing:
·
Local, Statewide, and Regional Collaboration- Continue to
collaborate with other agencies and organizations on climate change initiatives.
Work with the Governor’s office to implement policies and programs related to
climate change, including discussion/review of potential regional cap and trade
programs for load serving entities. Recognize and coordinate with the West
Coast Governors’ Global Warming Initiative and its proposed strategies to
reduce emissions and adapt to expected changes. Collaborate
with Public Utilities Commissions and Public Service Commissions in other
states to promote information sharing and coordination of efforts.
·
Best Practices- Facilitate communication among all utilities
to share best practices, key learnings, and to further develop a climate action
plan- including CPUC hosting of an all-industry open meeting in February 2005
on the topic.
·
Climate Action Registry- Continue to promote participation in the Climate
Action Registry by regulated utilities.
Expand encouragement to include non-residential participants in
ratepayer-funded energy efficiency programs and projects. Work with the Registry to incorporate its
protocols and knowledge, where appropriate.
Conclusion
Climate
change presents a unique and difficult challenge, and, ultimately, a potentially
devastating threat to California’s economic, environmental, and social
well-being. Fortunately, we are
constantly learning more about how to mitigate future changes and adapt to
expected changes to come. It is
only through immediate planning and action, that we can hope to reduce the
negative impacts within California and help lead the nation by demonstrating
enlightened leadership and a commitment to action.

* Because each policy was analyzed on a sequential basis, the
electricity emission savings for items lower on the list are much lower than
would be estimated if they were analyzed on their own (i.e. with no other
policies present). For example,
the efficiency activities reduce the amount of renewables needed to meet the
RPS targets. Similarly, a
smaller quantity of alternative fuels are needed for the 10% ethanol and 20% biodiesel
blends, because the LDV standards and freight strategies significantly lower fuel
demands. Were these strategies
considered first, or implemented alone, their emissions savings would appear
much larger. |
