California Bucks Global Trend with another Year of GHG Reductions

This post was co-authored by Maureen Lackner and originally appeared on the EDF Talks Global Climate blog.

The California Air Resources Board’s November 6 release of 2016 greenhouse gas (GHG) emissions data from the state’s largest electricity generators and importers, fuel suppliers, and industrial facilities shows that emissions have decreased even more than anticipated. California’s emissions trends are showing what is possible with strong climate policies in place and provide hope even as new analysis projects that global emissions will increase by 2% in 2017 after a three-year plateau.

California’s emissions kept falling in 2016

The 2016 emissions report, an annual requirement under California’s regulation for the Mandatory Reporting of Greenhouse Gas Emissions (MRR), shows that emissions covered by the state’s cap-and-trade program are shrinking, and doing so at a faster pace than in prior years. Covered emissions have dropped each year that cap and trade has been in place, amounting to 31 million metric tons of carbon dioxide-equivalent (MMt CO2e) over the whole period, or 8.8% reduction relative to 2012. The drop between 2015 and 2016 accounts for over half of these cumulative reductions (16 MMt CO2e; 4.8% reduction relative to 2015). The electricity sector is responsible for the bulk of this drop: electricity importers reduced emissions about 10 MMt CO2e while in-state electricity generation facilities reduced emissions by about 7 MMt CO2e.

Some sectors’ emissions grew in 2016. Just as with global transportation emissions, California’s transportation emissions have steadily crept up in recent years, and the MRR report suggests this trend is continuing. Transportation fuel suppliers, which account for the largest share of total emissions, reported a 1.8 MMt CO2e increase in emissions covered by cap and trade since 2015. Cement plants and hydrogen plants also experienced small increases in covered emissions. One of the benefits of cap and trade, however, is that if the clean transition is occurring more slowly in one sector, other sectors will be required to reduce further to keep emissions below the cap while the whole economy catches up.

Emissions that are not covered by the cap-and-trade program dropped, from 92 MMt CO2e in 2015 to 87 MMt CO2e in 2016. While small, this represents the largest reduction in non-covered emissions since 2012 and is mostly driven by suppliers of natural gas/NGL/LPG and electricity importers. Net non-covered and covered emissions reductions resulted in a 20.5 MMt CO2e drop in total emissions from these sectors.

These results are a welcome reminder that the cap-and-trade program is working in concert with other policies to accomplish the primary objective of reducing emissions.

The California climate policies are accomplishing their emissions reductions goals

The 2016 MRR data indicate impactful reductions in GHG emissions and progress toward reaching the state’s target emissions reductions by 2020. The 2016 emissions drop is a consequence of several factors: a CARB analysis of the year’s electricity generation points to increased renewable capacity, decreased imports of electricity from coal-fired power plants, and increased in-state hydroelectric power production. To put it in perspective, the 20.5 MMt CO2e emissions reductions is equivalent to offsetting the energy use of about 2.2 million homes, or 16% of California’s households.

Emissions below the cap are a climate win, not a concern

Total covered emissions in 2016 were about 324 MMt CO2e, well below California’s 2016 cap of roughly 382 MMt. Some observers of the cap-and-trade program worry that an “oversupply” of credits will result in reduced revenue for the state and lesser profits for traders on the secondary market. This concern was especially pronounced when secondary market prices dipped below the price floor in 2016 and 2017.

Importantly, oversupply of allowances is not a bad thing for the climate. As Frank Wolak, an energy economist at Stanford, points out, oversupply may be a sign of an innovative economy in which pollution reductions are easier to achieve than anticipated. Furthermore, having emissions below the cap represents earlier than anticipated reductions which is a win for the atmosphere. Warming is caused by the cumulative emissions that are present in the atmosphere so earlier reductions mean gases are not present in the atmosphere for at least the period over which emissions are delayed.

While market stability is a valid concern, the design of the program has built-in features to prevent market disruptions. Furthermore, the California legislature’s recent two-thirds majority vote to extend the cap-and-trade program through 2030 provides long-term regulatory certainty. Both the May and August auctions were completely sold out suggesting that the extension has succeeded in stabilizing demand.

These results are a welcome reminder that the cap-and-trade program is working in concert with other policies to accomplish the primary objective of reducing emissions, and that we’re doing it cheaply is an added bonus. Early reductions at a low cost can lead to sustained or even improved ambition as California implements its world-leading climate targets.

As California closes its fifth year of cap and trade, it should be with a sense of accomplishment and optimism for the future of the state’s emissions.

How climate policy can mitigate extreme weather's economic toll

 

This post was co-authored with Maureen Lackner

In the wake of hurricanes Harvey and Irma, Americans are coming together to support communities as they recover from the physical, emotional and economic toll after lives, possessions and livelihoods were washed away. Reestablishing daily routines, including work, school and regular commerce will take time, and for many, life may not return to what was once considered normal. But as we begin rebuilding what can be replaced, it is necessary to first gauge the scale and cost of the damage. It is also time to face the possibility that devastating weather events like Harvey and Irma may become the new normal

Harvey and Irma are among the most expensive hurricanes in U.S. history

Harvey and Irma have brought front and center the high costs of extreme weather-related disasters. While the damage is still being assessed, Harvey’s could cost as much as $200 billion, making it the most expensive natural disaster in U.S. history, surpassing Hurricane Katrina ($194 billion in 2017 USD). Estimates of Hurricane Irma’s economic damage are less certain, but the storm will likely also be among the most expensive weather-related disasters in the United States. (And we can’t forget that before reaching Florida, Irma caused damage to many Caribbean islands, which in some cases exceeded their GDP.)

While hurricanes tend to be the most dramatic, other types of severe weather also cause billions of dollars in economic damages. During the first half of 2017 alone, nine weather events including hailstorms, flooding, and tornados racked up $16 billion in damages across several states.

Climate change elevates the risk of severe weather events, and that comes at a cost

Climate change doesn’t cause hurricanes, but sea level rise and warmer temperatures make storms more destructive. Storm surges along the Texas coast where Hurricane Harvey hit are now about 7 inches higher than storm surges a few decades ago as a result of sea level rise, which can make a big difference in flooding. In addition, evaporation intensifies with warmer temperatures, which results in more moisture in the atmosphere and therefore higher rainfall amounts and flooding when storms make landfall. Warmer ocean temperatures also fuel hurricanes, making them more powerful. Hurricane Irma was a classic example of just how powerful a storm can get from increased ocean temperatures.

It is also possible that severe weather-related events overall are becoming more frequent. One recent EDF analysis shows that U.S. counties experienced, on average, a fourfold increase in the frequency of disaster level hurricanes, storms, and floods between 1997 and 2016 than in the 20 years prior. In the Southeast, this increase is even more pronounced; on average, its states experienced close to four-and-a-half times more disaster declarations over the same time period.

In the coming decades, risk of climate change-influenced severe weather will differ from region to region, but one thing is clear: if left unmitigated, the effects of climate change could come at serious economic costs, not just to those who lose homes and livelihoods, but to their insurance companies or to taxpayers. Other aspects of the economy could experience significant pain as well.

In the Southeast alone, higher sea levels resulting in higher storm surges could increase the average annualized cost of storms along the Eastern seaboard and Gulf Coast by $2-3.5 billion by 2030. In some areas, like Texas, where sea levels are rising faster than the global average, these increases even higher. Research published in Science suggests that even if storms themselves do not become more severe, direct annual economic damage could rise by 0.6 to 1.3% of state gross domestic product (GDP) for South Carolina, Louisiana, and Florida under median estimates of mean sea level rise. This translates into billions of dollars in additional economic damage every year for each of these states.

Hurricanes and severe storms pose serious risks to U.S. energy infrastructure

During Hurricane Katrina, the extent of the damages suffered by Entergy New Orleans forced the utility into bankruptcy. Hurricane Irma caused power outages in Florida that left over six million people without power.

Beyond these local impacts, these events can cause damage nationwide. Texas is home to about 30% of domestic oil and gas refining capacity, half of which was disrupted by Hurricane Harvey. This shut down 16% of the nation’s total refining capacity, spiked the average national gasoline price approximately 37 cents per gallon, and forced crude exports to drop from 749,000 to 153,000 barrels per day in the week after Harvey. As of September 10, 2017, more than two weeks after Hurricane Harvey made landfall, five Gulf Coast refineries remained closed, representing 11% of total Gulf Coast refining capacity and 5.8% of U.S. refining capacity.

The Trump administration should focus on adaptation and mitigation

In the short term, the Trump administration should maintain existing programs designed to enhance U.S. energy security and disaster response. For starters, the administration should stop dismantling EPA programs expressly designed to help communities respond to damage from storms.

In the long term, we need to build climate resilient communities and infrastructure, through efforts like wetland restoration and smart development. President Trump would also do well to listen to Miami’s Republican Mayor Tomás Regalado, and rethink his approach to climate policy. Instead of rolling back smart policies and regulations, or simply ignoring the impacts of climate change, we need to stop compounding the problem and mitigate the effects of a warmer climate through policy that sets aggressive emissions reduction targets. Such strategies will do much more than just protect our economy's bottom line—it will help ensure the safety, security, and well-being of millions of Americans.

Why the EPA gives Taxpayers the Biggest Bang for their Hard-earned Buck

This blog was co-authored with Gernot Wagner

The Trump administration’s proposed federal budget for fiscal year 2017 slashes the Environmental Protection Agency’s (EPA) budget by 31 percent, targeting an entity that already operates with one of the smallest budgets in the government – of every 10 dollars the federal government spends, EPA only gets 2 cents.

But absolute numbers aren’t the right metric. The big question is what the public (President Trump’s employer) gets for its investment. And using that metric, the EPA generates the biggest benefits of any agency, bar none.

 

 

Between 2005 and 2015, EPA regulations produced on average $9 in benefits for every $1 spent towards compliance. These benefits include: keeping Americans safe from dirty air, water, and dangerous chemicals – all of which can cause increased hospitalizations, missed work days, premature death, and birth defects. While numerous agencies across the federal government provide vital, lifesaving services, as well, EPA has the best benefits-to-costs ratio of any U.S. agency, according to the Office of Management and Budget (OMB), which produces an annual report tallying the benefits and the costs of major federal rules for every U.S. agency.

Total numbers are even more staggering: over those ten years, EPA is responsible for $376 billion in social benefits after subtracting the costs incurred by its regulations. That’s an order of magnitude higher than any other U.S. agency.

The message is clear: EPA provides large benefits at a bargain. In fact, while a high benefit-to-cost ratio is good, the goal isn’t to maximize the ratio. The goal is to maximize net benefits to society. EPA has been extremely successful at doing exactly that. Now is not the time to walk back that kind of progress.

The United States Could Lead the Next Tech Revolution by Investing in Clean Energy

New Risky Business Report Finds Transitioning to a Clean Energy Economy is both Technologically and Economically Feasible

In the first Risky Business report, a bi-partisan group of experts focused on the economic impacts of climate change at the country, state and regional levels and made the case that in spite of all that we do understand about the science and dangers of climate change, the uncertainty of what we don’t know could present an even more devastating future for the planet and our economy.

The latest report from the Risky Business Project, co-chaired by Michael R. Bloomberg, Henry M. Paulson, Jr., and Thomas F. Steyer, examines how best to tackle the risks posed by climate change and transition to a clean energy economy by 2050, without relying on unprecedented spending or unimagined technology. The report focuses on one pathway that will allow us to reduce carbon emissions by 80 percent by 2050 through the following three shifts:

1. Electrify the economy, replacing the dependence on fossil fuels in the heating and cooling of buildings, vehicles and other sectors. Under the report’s scenario, this would require the share of electricity as a portion of total energy use to more than double, from 23 to 51 percent.
2. Use a mix of low- to zero-carbon fuels to generate electricity. Declining costs for renewable technologies contribute in making this both technologically and economically feasible.
3. Become more energy efficient by lowering the intensity of energy used per unit of GDP by about two thirds.

New Investments Will Yield Cost Savings

Of course, there would be costs associated with achieving the dramatic emissions reductions, but the authors argue that these costs are warranted. The report concludes that substantial upfront capital investments would be offset by lower long-term fuel spending. And even though costs would grow from $220 billion per year in 2020 to $360 billion per year in 2050, they are still likely far less than the costs of unmitigated climate change or the projected spending on fossil fuels. They’re also comparable in scale to recent investments that transformed the American economy. Take the computer and software industry, which saw investments more than double from $33 billion in 1980 to $73 billion in 1985. And those outlays continued to grow exponentially—annual investments topped $400 billion in 2015. All told, the United States has invested $6 trillion in computers and software over the last 20 years.

This shift would also likely boost manufacturing and construction in the United States, and stimulate innovation and new markets. Finally, fewer dollars would go overseas to foreign oil producers, and instead stay in the U.S. economy.

The Impact on American Jobs

The authors also foresee an impact to the U.S. job market. On the plus side, they predict as many as 800,000 new construction, operation and maintenance jobs by 2050 would be required to help retrofit homes with more efficient heating and cooling systems as well as the construction, operation and maintenance of power plants. However, job losses in the coal mining and oil and gas sectors, mainly concentrated in the Southern and Mountain states, could offset these employment gains. As we continue to grow a cleaner-energy economy, it will be essential to help workers transition from high-carbon to clean jobs and provide them with the training and education to do so.

A Call for Political and Private Sector Leadership

Such a radical shift won’t be easy, and both business and policy makers will need to lead the transition to ensure its success. First and foremost, the report asserts that the U.S. government will need to create the right incentives.  This will be especially important if fossil fuel prices drop, which could result in increased consumption.  Lawmakers would also need to wean industry and individuals off of subsidies that make high-carbon and high-risk activities cheap and easy while removing regulatory and financial barriers to clean-energy projects. They will also need to help those Americans negatively impacted by the transition as well as those who are most vulnerable and less resilient to physical and economic climate impacts.

Businesses also need to step up to the plate by auditing their supply chains for high-carbon activities, build internal capacity to address the impacts of climate change on their businesses and put internal prices on carbon to help reduce risks.

To be sure, this kind of transformation and innovation isn’t easy, but the United States has sparked technological revolutions before that have helped transform our economy—from automobiles to air travel to computer software, and doing so has required collaboration between industry and policymakers.

We are at a critical point in time—we can either accelerate our current path and invest in a clean energy future or succumb to rhetoric that forces us backwards. If we choose to electrify our economy, reduce our reliance on dirty fuels and become more energy efficient, we will not only be at the forefront of the next technological revolution, but we’ll also help lead the world in ensuring a better future for our planet.

How Companies Set Internal Prices on Carbon

This post was co-authored with Elizabeth Medford

Despite the uncertainty created by the recent election, companies around the globe are demonstrating a commitment to keeping climate change in check. More than 300 American companies signed an open letter to President-elect Trump urging him not to abandon the Paris agreement. Others are acting on their own to reduce emissions in their daily operations, by setting an internal price on carbon.

The number of companies incorporating an internal carbon price into their business and investment decisions has reached new heights, a recent CDP report shows, with an increase of 23 percent over last year. The more than 1,200 companies that are currently using an internal carbon price (or are planning to within two years) are using them to determine which investments will be profitable and which will involve significant risk in the future, as carbon pricing programs are implemented around the world. Sometimes, they also use them to reach emissions reduction goals.

Not all carbon prices are created equal, and companies differ in how they set their specific price. Here’s a look at some of these methods:

Incorporating Carbon Prices from Existing Policies

 Some companies set their carbon price based on policies in the countries where they operate. For example, companies with operations in the European Union might decide to use a carbon price equal to that of the European Union Emissions Trading System (EU ETS) allowances, and those operating in the Northeastern United States might adopt the carbon price that results from the Regional Greenhouse Gas Initiative market.

ConocoPhillips, for example, focuses its internal carbon pricing practices on operations in countries with existing or imminent greenhouse gas (GHG) regulation. As a result, its carbon price ranges from $6-38 per metric ton depending on the country. For operations in countries without existing or imminent GHG regulation, projects costing $150 million or greater, or that results in 25,000 or more metric tons of carbon dioxide equivalent, must undergo a sensitivity analysis that includes carbon costs.

Using Self-Imposed Carbon Fees

Others take a more aggressive approach by setting a self-imposed carbon fee on energy use. This involves setting a fee on either units of carbon dioxide generated or a proxy measurement like energy use. These programs also often include a plan for using the fees such as investment in clean energy or energy efficiency measures. This can be an effective method for incentivizing more efficient operations.

Microsoft, for example, designed its own system to account for the price of its carbon emissions. The company pledged to make its operations carbon neutral in 2012 and does so through a “carbon fee,” which is calculated based on the costs of offsetting the company’s emissions through clean energy and efficiency initiatives. Each business group within Microsoft is responsible for paying the fee depending on how much energy it uses. Microsoft collects the fees in a “central carbon fee fund” used to subsidize investments in energy efficiency, green power, and carbon offsets projects. Still, by limiting carbon fees to operational activities, Microsoft has yet to address a large chunk of their emissions.

Setting Internal Carbon Prices to Reach Emissions Reduction Targets

 Other companies set an internal carbon price based on their self-adopted GHG emissions targets. This involves determining an emissions reduction goal and then back-calculating a carbon price that will ensure the company achieves its goal by the target date. This method is a broader approach focused more on significantly reducing emissions while also mitigating the potential future risk of carbon pricing policies.

Novartis, a Swiss-based global healthcare company, uses a carbon price of $100/tCO2 and cites potential climate change impacts as a motivator. The company has its own greenhouse gas emissions target, which it is using to cut emissions to half of its 2010 levels by 2030. These internal policies mean that Novartis, which is included in the European Union’s Emissions Trading Scheme (EU ETS), has been able to sell surplus allowances and thus far avoid an increase in operating costs.

Where we go from here

 While these internal carbon pricing activities are welcome – and we hope they continue – they are not sufficient to reduce greenhouse gases to the degree our nation or world requires. Like these forward thinking companies, nations around the world, including the United States, need to consider the costs of inaction, including the climate-related costs, to avoid short-sighted investments. Ultimately, we will need public policies that put a limit and a price on carbon throughout the economy.

The spread of internal carbon pricing could signal greater support for carbon pricing by governments. But companies can do more: the ultimate test of a company’s convictions and commitment to carbon pricing might be their willingness to advocate for well-designed, ambitious policies that achieve the reductions we need.

Good news in California as carbon auction results improve, and carbon emissions continue falling

Co-authored by Erica Morehouse and Jonathan Camuzeaux (this post was originally posted in EDF Talks Global Climate).

While we hope President-elect Trump will listen to the almost unanimous global voice of governments and business leaders who all understand that we must act to avert catastrophic climate change, it’s indisputable that leadership from U.S. states will be of paramount importance. Amidst this chaos and uncertainty California and Quebec are now four years into a successful cap-and-trade program with shrinking carbon pollution footprints and thriving economies.

California and Quebec released results today from a much anticipated carbon auction that took place on November 15, and sold a greater number of allowances than in the past two auctions resulting in proceeds for the state Greenhouse Gas Reduction Fund.  This good news comes after California’s 2015 greenhouse gas reporting data earlier this month showed another year of carbon pollution decline for the Golden State.

These year-over-year pollution declines are the most important indicator of success.  But understandably the auction performance and amount raised for climate investment priorities will get a lot of attention in California, Quebec, and Ontario, which is slated to launch its own cap-and-trade program in January with linkage likely to California and Quebec in 2018.

Auction results see increased demand

The November 15 auction offered more than 87 million current vintage allowances (available for 2016 or later compliance) and sold almost 77 million. Approximately 10 million future allowances were offered that will not be available for use until 2019 or later; over one million of those allowances were sold.

These auction results represent a significant increase in demand from the August auction which offered a similar number and sold about 31 million allowances, up from a little over eight million allowances sold at the May auction, the first auction to experience very low demand for allowances.  The May and August auctions raised almost no revenue for the California Greenhouse Gas Reduction Fund (GGRF).  While final numbers won’t come in for another few weeks, based on the allowances sold, this auction likely raised over $360 million for the California GGRF. 

Impacts on demand for this auction

A number of factors, good and otherwise, contributed to this quarter’s results.

  1. One of the most immediate factors that likely contributed to increased demand in this auction is the knowledge that the minimum sale price or “floor price” will rise to about $13.50 in 2017. This is the last auction that participants will be able to purchase allowances for $12.73 before the annual increase.
  1. A constant during this and previous auctions is litigation brought by the California Chamber of Commerce and others challenging California’s cap-and-trade program design. The case was brought the day before California’s very first auction in 2012 and California won at the trial court level. The plaintiffs appealed, and the Court of Appeals will hear oral arguments on January 24, 2017. This outstanding litigation may be leading some potential auction participants to take a wait-and-see approach.
  1. This wait-and-see approach is only possible if regulated businesses in California already have enough allowances to cover their 2016 obligations. California just released preliminary data for 2015 which shows emissions were about 14 percent below the cap. This suggests a successful set of climate policies that are incentivizing polluters to lower levels of pollution below required levels if they are able.  Some have referred to this as an oversupply of allowances, but it’s perhaps more accurate to refer to it as over-compliance.  Businesses have a choice of how to respond when they over-comply: avoid buying allowances in a future auction or buy allowances when they are presumably cheaper and bank them for future use.

A big question is how much the passage of SB 32 in August has impacted auction demand.  Governor Brown had previously established a target of reducing carbon pollution 40 percent below 1990 levels by 2030 through an executive order, but SB 32 cemented this requirement into law making it much more certain.  Setting a 2030target could increase demand for allowances, but the market will not necessarily get certainty about that target or how California will meet it in one fell swoop.  While SB 32 set the 2030 target, like AB 32 it was silent on policy tools to meet that target so decisions about cap-and-trade post-2020 are still outstanding.

Greenhouse gas emissions decline again in 2015

California’s Mandatory Greenhouse Gas Reporting program requires that state’s largest polluters to report their emissions annually. The California Air Resources Board released the final tally of 2015 greenhouse gas emissions on November 4th, which showed yet another year of carbon pollution decrease.

In 2015, California’s emissions covered under the cap-and-trade program decreased by roughly one percent compared to the year before. California is on track to meet its target of reducing pollution to 1990 levels by 2020.  Carbon pollution for capped and uncapped sources was down in 2015.

Meanwhile, data from the Bureau of Economic Analysis shows the state’s gross domestic product increased by almost six percent in 2015 – while California also experienced an increase of total employment of a little over two percent in 2015 – proving again that economic output and emissions don’t necessarily go hand in hand.

With these results California is on solid footing to continue as a beacon of hope for climate action in the United States and perhaps even to attract new partners inside or outside the country who are ready to join a successful program.
