A new C2ES report highlights lessons useful for companies and policymakers as more states and countries consider carbon pricing to spur innovative technologies and cut emissions at the lowest possible cost.
The report, written for the World Bank’s Partnership for Market Readiness (PMR), examines how three companies — Pacific Gas and Electric (PG&E), Rio Tinto, and Royal Dutch Shell -- prepared for carbon pricing programs.
The PMR shares this type of information with developing countries to help them create their own market-based policies. We were pleased to partner with the PMR to explore how a few of the companies in our Business Environmental Leadership Council prepared for carbon pricing and we thank the companies for sharing their expertise.
The lessons they shared fall into two categories – what business can learn from other companies operating in carbon markets and what governments considering market-based climate policy can learn from business.
Lessons for companies include:
- Incorporate climate change into a company’s strategy. Regulations to curb greenhouse gas emissions can affect many industries, especially those that are energy-intensive. Companies need top-level support for a comprehensive climate change strategy that leverages expertise across the company. For instance, in 1998, Shell conducted its first formal study on the potential impact of climate-related regulations on its global business. Then managing director and later CEO Jeroen van der Veer was the driving force behind the study, which built an internal case for climate action.
- Monitor, report, and verify (MRV) greenhouse gas emissions. A first step is often to build a greenhouse gas inventory. The inventory helps a company understand its direct and indirect emissions and anticipate its exposure to new carbon pricing regulation. For example, some of Rio Tinto’s units started collecting inventory emissions as far back as the mid-1990s, several years before any regulations required them to do so. Today, Rio Tinto continues to measure and report on emissions from most operations, even in jurisdictions where there is no reporting requirement.
- Identify risks and opportunities. By engaging in the policymaking process, companies can reduce uncertainty as well as identify business opportunities.
- Build knowledge and skill early. There are many ways to increase company knowledge of future carbon policies, such as participating in a voluntary offset market to understand the methodologies, rules, and processes for acquiring carbon credits. PG&E gained experience with offsets in 2007 through its ClimateSmart program. Working with the Climate Action Reserve, PG&E supported the development of several offset protocols, and some of the protocols were later adopted by California’s cap-and-trade program. These activities can also build in-house expertise, including how to handle carbon trading transactions.
Lessons for policymakers include:
- Create a predictable regulatory environment. An environment of predictability, consistency, and flexibility is key to helping companies plan with confidence.
- Introduce early emissions reporting. Introducing reporting requirements in advance of carbon pricing regulations gives companies time to build an inventory of accurate emissions data.
- Include flexible market mechanisms. Certain design features, such as offsets and the banking and/or borrowing of allowances, can provide flexibility and improve the efficiency of a new program.
- Balance stakeholder interests. Each company and sector will have its own set of interests under a carbon pricing regime. The goal is to balance different interests and find solutions that benefit society as a whole.
The lesson for both companies and policymakers is that for an emissions policy to meet government objectives in a way that is also workable for the business community, it is crucial to create an open and transparent dialogue. This dialogue is essential as more states and countries look to carbon pricing.
Almost 40 countries and more than 20 cities, states, and provinces already use carbon pricing mechanisms or are planning to implement them. South Korea launched its carbon pricing program in January. China is running pilot carbon pricing programs in seven cities and two provinces and intend to release a plan for a national program next year. South Africa will also implement a carbon pricing program next year.
More than a quarter of the U.S. population lives in a state with a price on carbon, and some states may consider the policy as a way to implement new power plant emissions standards.
Getting ahead of the curve and preparing for these programs is just sound business strategy.
Most people at some point develop a “Plan B” – in case their first choice of college doesn’t accept them, or it rains on the day of their planned outdoor party, or the deal for the house they wanted falls apart. The same principle applies for more dire situations, such as a city having plans in hand for an orderly evacuation in case of a large-scale disaster. We hope such an event will never happen, but the mayor had better be prepared in case it does.
In a commentary today in the scientific journal Nature Climate Change, three colleagues and I discuss the need for a “Plan B” for climate change: How will we cope with increasingly severe climate impacts if we are unsuccessful in limiting global warming to a chosen target?
In the 2009 Copenhagen climate accord, countries set a goal of limiting global warming to below 2 °C (3.6 °F) above the average global temperature of pre-industrial times. However, given that the planet has already warmed by 0.8 °C, additional warming is already locked into the system, and global greenhouse gas emissions continue to rise, this “Plan A” has become increasingly difficult and may become impossible to achieve if widespread emissions reductions do not begin within this decade. A maximum warming target is a necessary goal of climate policy, but what if our efforts fall short?
Some voices in the environmental community will feel that asking this question is ceding failure, but I disagree. Instead, it means admitting that we can’t perfectly foresee the future and that we need to be prepared for surprises. This is called risk management and everyone from parents, to mayors, to companies, to the U.S. military uses risk management every day to cope with uncertainty.
Extreme Weather Event Map: Click on any circle to learn about one of the billion-dollar weather events, or any state to learn about billion-dollar droughts. All events occurred between 2000 and 2013.
This map shows billion-dollar weather events in the United States since 2000, as identified by the National Oceanic and Atmospheric Administration’s National Climatic Data Center. The Top 10 costliest events are listed at the bottom of this page, along with a description of major U.S. droughts since 2000.
Floods, Tornadoes, Thunderstorms, Hail, Tropical Storms, Wildfires, and Winter Storms are all shown as circles, with the costs indicated by the area of the circles (see image to the right). The location of the circles correspond to places where impacts were experienced (note: locations are approximate; many of the events actually impacted a large area, beyond
the boundaries of the circle). Droughts are not shown by circles, but by the shading in the states – states with darker colors have experienced more droughts since 2000, while states that are lightly shaded have experienced fewer droughts. No billion dollar events have occurred in Hawaii since 2000; some of the wildfire impacts (e.g., fire seasons in 2006, 2007, and 2008) included damages in Alaska, but the markers appear in the continental United States.
Many of these events, including heat waves and heavy rainfall, are likely to become more frequent and intense as a result of climate change. Climate change can also worsen the impacts of some of these events. For example, sea level rise can increase the impacts of coastal storms and warming can place more stress on water supplies during droughts. But it’s important to note that not ALL of these events will necessarily happen more frequently as a consequence of climate change. The links between climate change and tornadoes, ice storms, and hail are unclear, and represent current areas of research.
These events demonstrate ways our communities and infrastructure are vulnerable to extreme weather, and that the costs associated with impacts can be large.

Weathering the Storm - Extreme weather is costly. The events shown on the map above all cost billions of dollars, and several events had widespread and long-lasting implications.
C2ES has investigated how companies are perceiving the risks associated with extreme weather and climate change. Focusing on Standard and Poor’s (S&P) Global 100 companies, we found that 90 percent of these companies identify extreme weather and climate change as risks, and most have experienced climate impacts or expect to within 10 years. Although some companies have taken action, only a few have used climate-specific tools to comprehensively assess risks and develop resilience plans.

Extreme Weather and Climate Change
Understanding the Link, Managing the Risk
Updated December 2011
Thousands of record-breaking weather events worldwide bolster long-term trends of increasing heat waves, heavy precipitation, droughts and wildfires. A combination of observed trends, theoretical understanding of the climate system, and numerical modeling demonstrates that global warming is increasing the risk of these types of events today. Debates about whether single events are “caused” by climate change are illogical, but individual events offer important lessons about society’s vulnerabilities to climate change. Reducing the future risk of extreme weather requires reducing greenhouse gas emissions and adapting to changes that are already unavoidable.
Typically, climate change is described in terms of average changes in temperature or precipitation, but most of the social and economic costs associated with climate change will result from shifts in the frequency and severity of extreme events. This fact is illustrated by a large number of costly weather disasters in 2010, which tied 2005 as the warmest year globally since 1880. Incidentally, both years were noted for exceptionally damaging weather events, such as Hurricane Katrina in 2005 and the deadly Russian heat wave in 2010. Other remarkable events of 2010 include Pakistan’s biggest flood, Canada’s warmest year, and Southwest Australia’s driest year. 2011 continued in similar form, with “biblical” flooding in Australia, the second hottest summer in U.S. history, devastating drought and wildfires in Texas, New Mexico and Arizona as well as historic flooding in North Dakota, the Lower Mississippi and in the Northeast.
Munich Re, the world’s largest reinsurance company, has compiled global disaster for 1980-2010. In its analysis, 2010 had the second-largest (after 2007) number of recorded natural disasters and the fifth-greatest economic losses. Although there were far more deaths from geological disasters—almost entirely from the Haiti earthquake—more than 90 percent of all disasters and 65 percent of associated economic damages were weather and climate related (i.e. high winds, flooding, heavy snowfall, heat waves, droughts, wildfires). In all, 874 weather and climate-related disasters resulted in 68,000 deaths and $99 billion in damages worldwide in 2010.
The fact that 2010 was one of the warmest years on record as well as one of the most disastrous, begs the question: Is global warming causing more extreme weather? The short and simple answer is yes, at least for heat waves and heavy precipitation. But much of the public discussion of this relationship obscures the link behind a misplaced focus on causation of individual weather events. The questions we ask of science are critical: When we ask whether climate change “caused” a particular event, we pose a fundamentally unanswerable question (see Box 1). This fallacy assures that we will often fail to draw connections between individual weather events and climate change, leading us to disregard the real risks of more extreme weather due to global warming.
Climate change is defined by changes in mean climate conditions—that is, the average of hundreds or thousands events over the span of decades. Over the past 30 years, for example, any single weather event could be omitted or added to the record without altering the long-term trend in weather extremes and the statistical relationship between that trend and the rise in global temperatures. Hence, it is illogical to debate the direct climatological link between a single event and the long-term rise in the global average surface temperature.
Nonetheless, individual weather events offer important lessons about social and economic vulnerabilities to climate change. Dismissing an individual event as happenstance because scientists did not link it individually to climate change fosters a dangerously passive attitude toward rising climate risk. The uncertainty about future weather conditions and the illogic of attributing single events to global warming need not stand in the way of action to manage the rising risks associated with extreme weather. Indeed, such uncertainty is why risk managers exist – insurance companies, for example – and risk management is the correct framework for examining the link between global climate change and extreme weather.
An effective risk management framework accommodates uncertainty, takes advantage of learning opportunities to update understanding of risk, and probes today’s rare extreme events for useful information about how we should respond to rising risk. Risk management eschews futile attempts to forecast individual chaotic events and focuses on establishing long-term risk certainty; that is, an understanding of what types of risks are increasing and what can be done to minimize future damages. An understanding of the meaning of risk and how it relates to changes in the climate system is crucial to assessing vulnerability and planning for a future characterized by rising risk.

The risk of extreme weather is rising because of climate change. In the United States, long-term trends show an increasing number of heat waves and heavy downpours and longer, more destructive droughts and wildfires. Climate models simulate these same trends when scientists examine the effects of increases in global warming’s main ingredient – greenhouse gases.
Risk is the best way to understand the link between climate change and extreme weather. Just as smoking and high cholesterol are risk factors for heart disease, natural cycles and global warming are risk factors for extreme weather. This year’s weather impacts have been particularly severe because multiple risk factors are aligned: A long, intense La Nina – a temporary cool period in the equatorial Pacific Ocean that is associated with extreme temperatures, droughts, and flooding in other parts of the world – is occurring at the same time we are experiencing the warmest decade in at least 130 years. The big difference between these risk factors is that natural cycles come and go, whereas global warming increases over time as atmospheric greenhouse gases grow, constantly adding more weather risk to the climate system.
Escalating weather impacts are cutting deeply into the economy. The world’s largest re-insurance company says the number of weather- and climate-related disasters worldwide more than doubled over the past 30 years. Economic losses attributable to weather variability run $485 billion annually. Several multi-billion-dollar events have occurred this year, including Texas’ worst single-year drought, the Mississippi floods, and Hurricane Irene, which is expected to rank among the ten costliest hurricanes in U.S. history. As the weather becomes more volatile, economic risk will continue to grow.
As recent weather events teach us more and more about our vulnerabilities, the taxpayer-funded National Flood Insurance Program is already $18 billion in debt. Because most of the damage from Hurricane Irene is not privately insured, this financially-strapped program is under pressure once again. And the Federal Emergency Management Agency (FEMA) is running out of money to respond to disasters, even as Congress bickers over how to refill the coffers.
Flood insurance is the federal government’s second-largest fiscal liability after social security. Ignoring rising climate risk will only allow these hidden costs to suck up more taxpayer money. Reducing greenhouse gas emissions and adapting to changes already under way bends down the risk curve, just as exercise and medical insurance lower health risks. If we don’t take these steps, our children and grandchildren will inherit a more dangerous and costlier climate.
