What You Need to Know About Article 6 of the Paris Agreement

By Kelley Kizzier / Published: December 2, 2019

This post was coauthored by Kelley Kizzier from EDF, Kelly Levin from World Resources Institute, and Mandy Rambharos, Article 6 negotiator, South Africa. It originally appeared on WRI’s blog. 

As delegates arrive in Madrid for the UN Climate Change Conference (COP25) this week, one issue is top-of-mind: finalizing the rules on how countries can reduce their emissions using international carbon markets, covered under Article 6 of the Paris Agreement on climate change.

Article 6 is one of the least accessible and complex concepts of the global accord. This complexity was a major reason that Article 6 was not agreed to until the last morning of the Paris negotiations in 2015 and was left unresolved at the Katowice climate talks last year. Getting these rules right is critical for fighting climate change: depending on how they are structured, Article 6 could help the world avoid dangerous levels of global warming or let countries off the hook from making meaningful emissions cuts. The integrity of the Paris Agreement and countries’ climate commitments hang in the balance.

Here’s what you should know:

How do international carbon markets work?
International carbon markets work like this: Countries that struggle to meet their emissions-reduction targets under their national climate plans (known as “nationally determined contributions,” or NDCs), or want to pursue less expensive emissions cuts, can purchase emissions reductions from other nations that have already cut their emissions more than the amount they had pledged, such as by transitioning to renewable energy. If the rules are structured appropriately, the result can be a win-win for everyone involved — both countries meet their climate commitments, the overachiever is financially rewarded for going above and beyond, finance is provided to the country generating the emissions reductions, and the world gets a step closer to avoiding catastrophic climate change.

What does the Paris Agreement say about carbon markets?
Article 6 has three operative paragraphs, two of which relate to carbon markets:

  • Article 6.2 provides an accounting framework for international cooperation, such as linking the emissions-trading schemes of two or more countries (for example, linking the European Union cap-and-trade program with emissions-reduction transfers from Switzerland). It also allows for the international transfer of carbon credits between countries.
  • Article 6.4 establishes a central UN mechanism to trade credits from emissions reductions generated through specific projects. For example, country A could pay for country B to build a wind farm instead of a coal plant. Emissions are reduced, country B benefits from the clean energy and country A gets credit for the reductions.
  • Article 6.8 establishes a work program for non-market approaches, such as applying taxes to discourage emissions. For this explainer, we will focus on the carbon markets elements of Article 6.

While Article 6 established these concepts in broad strokes and countries achieved some progress on defining the rules over the years, their final shape remains yet to be agreed. Finalizing these rules is a key agenda item for COP25.

Today’s solid results from the latest Western Climate Initiative cap-and-trade auction demonstrate once again the resilience of the market. Yet this is not the only interesting news out of the California market this quarter as the state released the preliminary 2018 emissions inventory, which showed that transportation emissions fell for the first time since 2012.

First up, auction results:

  • All 67,435,661 current allowances sold, clearing at $17.00, $1.38 above the floor price of $15.62. This is $.16 lower than the August 2019 clearing price of $17.16.
  • All of the 9,038,000 future vintage allowances offered also sold at $16.80, $1.18 above the $15.62 floor price. These allowances are not available for use until 2022.
  • The auction raised approximately $739 million for the Greenhouse Gas Reduction Fund, which California uses for activities that further decrease greenhouse gas emissions, improve local air quality, and support the state’s most vulnerable communities.
  • Quebec raised over approximately $245 million CAD (approximately $185 million USD) to fund their own climate priorities.

These results are generally consistent with the past several auctions, but there are a couple of points worth noting:

Two new analyses: significant benefits for Pennsylvania from historic move to limit carbon pollution

By Rama Zakaria / Published: November 21, 2019

(This post was co-written by Mandy Warner)

Two new analyses show significant opportunities for Pennsylvania under environmental protections that are compatible with the Regional Greenhouse Gas Initiative – commonly known as RGGI.

RGGI is a collaboration of nine northeast states that is designed to lower carbon pollution from the power sector. Pennsylvania Governor Tom Wolf signed an historic executive order last month directing the state’s Department of Environmental Protection to develop a regulation that is compatible with RGGI. That order followed Wolf’s commitment to reducing Pennsylvania’s climate pollution by 26 percent by 2025 and 80 percent by mid-century, compared to 2005 levels.

Pennsylvania has the fifth dirtiest power sector in the nation, and the power plants operating in Pennsylvania emit more carbon pollution than all the other power plants in the nine northeastern states in RGGI combined. A binding, declining limit on carbon pollution is a necessary element of any strategy to address this problem.

Two studies underscore the value of Pennsylvania’s actions:

  • EDF and M. J. Bradley & Associates released a new analysis that found there could be significant economic and emissions reduction benefits for Pennsylvania from setting a binding, declining limit on power sector carbon pollution, and creating a flexible, market-based mechanism to achieve that limit. The analysis was based on policy specifications, inputs, and assumptions developed by M.J. Bradley & Associates at the direction and on behalf of EDF, with feedback from participating stakeholder companies.
  • A recent report by Resources for the Future had similar findings.

Here are five key takeaways from both of these analyses.

  1. Pennsylvania has a significant opportunity for cost-effective pollution abatement by limiting carbon pollution and linking with RGGI

While carbon pollution from Pennsylvania’s power sector has declined in recent years, driven primarily by market trends including cheap natural gas prices, it is projected to start increasing again. By mid-2020, under business-as-usual forecasts with no carbon limits, both analyses found Pennsylvania’s power sector carbon pollution would be more than 30 percent higher than current levels.

By setting a binding, declining limit on power sector carbon pollution and creating a flexible, market-based mechanism to achieve that limit, Pennsylvania can significantly reduce its carbon pollution at low cost.

The EDF and M.J. Bradley & Associates analysis found that linking with RGGI and designing the program in a way that ensures all electric power used in Pennsylvania is covered under the cap could lower carbon pollution by more than 35 percent and produce roughly $200 million in net savings for Pennsylvania in 2030. That’s compared to business-as-usual scenarios with no carbon limit.

The lower costs are due to reduced need for capital expenditures like building new power plants, and to declining fossil fuel costs – both driven by more of the existing nuclear fleet remaining in operation.

Resources for the Future’s analysis similarly found that linking with RGGI could lead to significant carbon pollution reductions in Pennsylvania with no observable increases in electricity prices.

Earlier studies have also demonstrated the benefits of RGGI. By driving investments in energy efficiency, RGGI has already reduced consumer energy bills, generated net economic benefits for participating states, and has  produced enormous public health benefits. RGGI has helped save hundreds of lives, prevented thousands of asthma attacks, and saved billions of dollars in health-related economic costs.

According to electricity bill modeling by the Analysis Group, the average residential electricity bill in RGGI states will be 35 percent lower in 2031 than it is today, due to investments in energy efficiency.

Linking Pennsylvania with RGGI could offer further benefits – including allowing for emissions trading, which can lower total costs and make Pennsylvania’s program resilient to unexpected changes in weather or other events that could affect electricity markets while still preserving state autonomy and programs.

  1. Limiting carbon pollution and linking with RGGI provides support for existing and new zero-emission generation

Placing a binding, declining limit on carbon pollution – and then letting the carbon pollution limit drive a price in the energy market – provides Pennsylvania with a technology-neutral approach that ensures the most cost-effective deployment of zero-emission resources to meet the state’s climate goals.

The EDF and M.J. Bradley & Associates analysis found that under business-as-usual scenarios using EDF’s reference natural gas price assumptions, all nuclear capacity in Pennsylvania retires by 2030.

According to the analysis, linking with RGGI and designing the program in a way that ensures all electric power used in Pennsylvania is covered under the cap can help support the state’s existing nuclear fleet – retaining roughly 50 percent of the fleet in 2030.

Resources for the Future similarly found that limiting carbon pollution and linking with RGGI would forestall expected nuclear retirements, increasing Pennsylvania’s nuclear generation by up to 280 percent in 2026 relative to business-as-usual scenarios.

The natural gas prices used by Resources for the Future for their analysis are higher than currently observed, which would allow nuclear capacity to remain profitable with greater ease than may be possible with lower natural gas prices. But the preservation of existing nuclear capacity is a robust result under all scenarios that limit carbon pollution across both analyses, providing valuable insight into the role a limit on carbon pollution can play in preserving assets that are zero-emitting.

The EDF and M.J. Bradley & Associates analysis also found that linking with RGGI can increase wind and solar generation in Pennsylvania by almost 75 percent in 2030 compared to current levels. Resources for the Future found that limiting carbon pollution and linking with RGGI could generate up to 25 percent more wind and solar generation in Pennsylvania by 2026 compared to business-as-usual scenarios.

  1. Pennsylvania can reduce carbon pollution while increasing net exports from the state

The EDF and M.J. Bradley & Associates analysis shows that limiting carbon pollution and linking with RGGI would enable Pennsylvania to achieve its environmental objectives at low cost while at the same time increasing net exports from the state at least nine percent in 2030 compared to current levels.

Pennsylvania can also design its program to shift allowance value to producers with updating output-based allocation, which can increase gas and nuclear generation and energy exports in the state. According to Resources for the Future, the production incentive from output-based allowance allocation can increase exports from Pennsylvania above business-as-usual levels by 2026. Most of these exports are to other RGGI states so the overall pollution in the region is unaffected.

Resources for the Future also finds that using an output-based allowance allocation to non-emitting producers can provide incentives to shift generation in Pennsylvania from fossil fuel to zero-emitting sources, further decreasing carbon pollution in Pennsylvania and nationally.

  1. Smart policy design can amplify these benefits and further lower overall pollution

When a state or group of states puts a limit on carbon pollution, particularly in states that are served by a multi-state wholesale electricity market, emissions leakage to emitting sources that are not covered under the program is always a concern.

While both analyses demonstrate clearly that such leakage will not even come close to dwarfing the significant climate benefits of Pennsylvania’s program, it may partially erode the potential for greater pollution reductions. Linking programs can help reduce leakage but is not sufficient to fully mitigate it.

The EDF and M.J. Bradley & Associates analysis finds that an effective leakage mitigation mechanism, such as putting emissions associated with imported power under the cap, can lower overall carbon pollution – driving 75 percent more reduction in pollution in the Eastern Interconnect in 2030. The analysis also shows that leakage mitigation can help provide more support for Pennsylvania’s existing nuclear fleet and lower overall system costs, more than doubling nuclear generation in the state and lowering system costs by roughly $330 million in 2030 compared to no leakage mitigation.

Pennsylvania has options available today to mitigate leakage concerns and ensure that the state is not disadvantaged in the broader marketplace relative to other states that choose not to control carbon pollution. Resources for the Future has shown that an output-based allowance allocation to producers has the potential to result in negative leakage.

Regional transmission organization PJM Interconnection is also looking into ways to enhance technical capabilities to support state policy choices such as carbon limits. As part of its Carbon Pricing Senior Task Force, PJM is actively exploring with its stakeholders what data needs and frameworks can best support state carbon outcomes in the context of a regional market. They are also considering ways to ensure that states that are controlling carbon are seeing those policy choices accurately reflected.

This PJM stakeholder process provides an important opportunity for Pennsylvania to engage to ensure the state has the information it needs to deploy the policy frameworks that can effectively mitigate leakage.

  1. More ambitious carbon pollution limits can provide even further benefits

The EDF and M.J. Bradley & Associates analysis also finds that more ambitious carbon pollution limits (in line with deep decarbonization trajectories) with leakage mitigation can accelerate pollution reductions, retain all of the state’s existing nuclear fleet, and incent new clean energy resource builds – all at lower system costs compared to business as usual scenarios with no carbon limit.

According to the analysis, more ambitious carbon pollution limits can increase solar capacity in Pennsylvania by more than 10 times, leading to an increase in renewable generation of more than 130 percent in 2030 compared to business-as-usual scenarios.

Public support for concrete climate policy is sky-high in Pennsylvania

There is strong support in Pennsylvania for moving forward to reduce carbon pollution.

A poll conducted by EDF Action earlier this year found that 79 percent of Pennsylvania voters support regulations to reduce carbon pollution. That includes 66 percent of state Republicans polled.

Major Pennsylvania power companies, including Exelon and FirstEnergy, applauded Governor Wolf’s executive order. The Pennsylvania Chamber of Commerce noted that “climate change is real” and that the business community needs to be “at the table to discuss solutions.”

The time for action is now

It is becoming increasingly urgent to address climate change. That means it is critical for Pennsylvania to move forward without delay, and put in place an ambitious program to secure carbon pollution reductions and lock in public health benefits at the lowest cost.

The good news is that Pennsylvania can build on planning it has already completed as part of previous compliance work. Governor Wolf’s executive order sets a deadline of July 31, 2020 for a proposed rule to cut carbon emissions to be presented to the Environmental Quality Board. But there’s no reason not to move forward more quickly.

We urge Governor Wolf to develop a proposed rule to submit to the Air Quality Technical Advisory Committee at its February meeting. That would help create certainty about the state’s emissions trajectory on a short-term time horizon, including creating regulatory certainty for affected industries.

Public records confirm EPA’s “censored science” proposal was an end-run around Congress

By Ben Levitan / Published: November 12, 2019

The Trump administration is reportedly expanding its dangerous plan — originally proposed by former Administrator Scott Pruitt — to limit the scientific evidence that the agency can consider when establishing public health protections.

According to a story in the New York Times today, the new proposal will be even more damaging than Pruitt’s version – which was flatly illegal and would have left Americans more exposed to dangerous contaminants in the air we breathe, the water we drink, and the products we use.

The original proposal was based on failed congressional legislation whose sponsor “pitch[ed]” the idea to former EPA Administrator Scott Pruitt. But newly released public documents show that the origins of the “censored science” proposal are more cynical than we knew.

EDF sued to obtain the public records after EPA violated the Freedom of Information Act (FOIA) by not releasing them, with Earthjustice representing us in the litigation.

The new public records reveal just how explicitly Trump’s EPA is attempting to defy Congress by implementing its “censored science” policy through administrative rulemaking. It turns out that – from the beginning – EPA’s overt goal was to implement the same damaging ideas that the Senate refused to pass. Read More »

The pollution-enabling impacts of the Clean Power Plan “replacement”

By Taylor Bacon / Published: October 30, 2019

EPA Administrator Andrew Wheeler has suggested that ACE – the Trump administration’s harmful and deeply flawed replacement for the Clean Power Plan – is just as effective in protecting climate and public health as its predecessor.

Wheeler is wrong.

ACE will achieve virtually no reductions in carbon pollution from power plants and will increase health-harming pollution in many communities across the country. This harmful rule represents a huge step backwards at a time when communities across the nation are increasingly suffering devastating impacts from climate change – such as wildfires, extreme weather, coastal flooding, and intense heat waves – that underscore the need for rapid reductions in carbon pollution.

Following the finalization of the ACE rule in June, Wheeler said that when the rule is fully implemented, “we expect to see U.S. power sector CO2 emissions fall by as much as 35 percent below 2005 levels.”

What that claim fails to acknowledge is – that based on EPA’s own analysis – these reductions are projected to occur whether or not there is a federal policy in place. In other words, the ACE rule will accomplish no significant carbon pollution reductions beyond business-as-usual. By claiming credit for reductions that would happen anyway, Wheeler is simply masking the inefficacy of the rule.

The Clean Power Plan was the first-ever policy to set national limits on harmful carbon pollution from existing power plants. The ACE rule, in contrast, contains no binding limits on carbon pollution. Instead, the rule merely provides a list of “heat rate improvement measures” that would incrementally improve the operating efficiency of coal plants, leaving it up to the states to decide which – if any – of those measures to apply.

When the Clean Power Plan was finalized in 2015, EPA projected that power sector carbon pollution would be 17 percent below 2005 levels in 2030 under business-as-usual with no federal policy. Due to the plummeting costs of clean energy technologies and the ongoing market shift towards cleaner electricity sources, EPA now projects that power sector carbon pollution under business-as-usual with no federal policy will be much lower, at 35 percent below 2005 levels in 2030. According to EPA, the ACE rule is projected to achieve a trivial 0.7 percent reduction in carbon pollution compared to business-as-usual in 2030.

Worse still, EPA’s own numbers show that the rule would have the perverse impact of incentivizing some coal-fired power plants to operate and pollute more – leading to more carbon pollution in many states compared to no policy at all.

Experts have warned that under the ACE rule, many parts of the country would also see increases in the health-harming pollution that leads to soot and smog. While the Trump administration has tried to downplay the public health consequences of the rule, EPA’s projections show that vulnerable communities around the nation will likely suffer the most from these dangerous pollution increases.

In addition to disregarding the health and well-being of Americans, the years-long effort by the Trump administration to dismantle the Clean Power Plan represents a squandered opportunity to cost-effectively achieve urgently needed reductions in pollution. EDF filed comments on the proposed rule that demonstrate that fact. Our updated analysis using the same power sector model that EPA relies upon shows that carbon pollution reductions of more than 50 percent below 2005 levels in 2030 are possible at similar costs to what the original Clean Power Plan envisioned. The U.S. Energy Information Administration has also found that even greater reductions of 68 percent below 2005 levels can be achieved by 2030 – along with steep reductions in dangerous soot and smog-forming pollution – at modest cost.

Not only are significant reductions in carbon pollution from the power sector possible, they are also long overdue. We are already facing serious consequences from carbon pollution. The latest reports from the Intergovernmental Panel on Climate Change make it frighteningly clear that the country and the world are facing unprecedented threats from climate change – and that rapid reductions in climate-destabilizing pollution are needed by 2030 in order to avoid the worst impacts. The devastation from climate change-fueled disasters across the U.S. and the millions of Americans suffering from the health impacts of air pollution underscore the pressing need for reductions in pollution from the power sector, one of the nation’s leading contributors to carbon pollution.

We need real protections against the dangerous carbon pollution that threatens both our environment and our health – not spin from Administrator Wheeler that hides the real impacts of his pollution-enabling rule behind misleading statistics.

100% Clean: How Do We Actually Get There?

By Steve Capanna / Published: October 22, 2019

For the U.S. to do its part to help avoid the worst impacts of climate change, we must achieve a 100% clean economy by 2050 at the latest – removing at least as much climate pollution from the atmosphere as we put into it each year. (Read this for more on what we mean by “100% clean” or why this should be the goal.)  But what does a 100% clean economy actually look like and how do we get there?

Several studies have examined how the U.S. can cut emissions 80% from 2005 levels by 2050, such as the Obama Administration’s Mid-Century Strategy for Deep Decarbonization. More recently, Evolved Energy’s 350 ppm Pathways for the United States became the first major report to identify pathways for the U.S. to achieve even deeper reductions: net-zero carbon dioxide (CO­2) emissions by 2050.

A 100% clean economy by 2050 is ambitious but necessary. To achieve it, we’ll need policies that drive down  climate pollution and substantial acceleration of clean energy innovation. Deep decarbonization studies suggest that with comprehensive climate policy and technology progress as a foundation, a 100% clean economy will most likely rely on:

  • Rapidly transitioning to a clean electricity system. We already have a good idea of how to clean up the electricity sector. Several zero-carbon sources (wind, solar, hydro, nuclear) have been widely deployed and are already among the most cost-effective options for new generation. As a result, the electricity sector is likely to transition quicker and more cost effectively than any other part of the economy.
  • Electrifying as much as possible. Electrifying major sectors like transportation and buildings cuts fossil fuel use and reduces emissions even with today’s electricity mix. It will lead to even greater reductions as electricity gets cleaner.
  • Deploying low carbon fuels where electrification isn’t practical. Cleaner alternatives to fossil fuels, including hydrogen, synthetic gas, and biofuels can fill in where electrification is tricky, such as for high temperature heat needed for manufacturing processes and in aviation.
  • Advancing energy efficiency. Energy efficiency lowers the amount of energy required—and therefore the emissions produced. Today, there are cost-effective energy efficiency opportunities in every sector of the economy, from vehicles to appliances to industrial equipment. As technology improves, even more opportunities to save energy while saving money will become available.
  • Removing carbon dioxide from the atmosphere. Protecting and increasing natural carbon “sinks” like forests or by deploying technologies that suck CO2 directly out of the air can help lower concentrations of carbon dioxide in the atmosphere, helping us reach 100% clean as quickly as possible. Also, because it will be very challenging to completely eliminate emissions from all parts of the economy, especially industry and transportation, carbon dioxide removal (CDR) can help ensure we’re taking as much carbon out of the atmosphere as we’re putting into it. There is disagreement over how big the potential carbon sink is from natural sources (the Evolved study, for instance, assumes the potential for natural CDR is large relative to other estimates). To the extent less natural CDR is available, we will need more technological CDR or more carbon mitigation.
  • Reducing non-CO2 CO2 is the dominant climate pollutant responsible for climate change, but there are other major greenhouse gases that trap more heat on a per ton basis, such as methane, nitrous oxide and hydrofluorocarbons (HFCs). These gases are emitted not only through energy consumption but as byproducts of a wide variety of activities such as agriculture, oil and gas industries, landfills, and refrigeration and air conditioning. There are various strategies available to reduce these greenhouse gas emissions, but some sources are easier to reduce than others. For example, cutting edge techniques to limit methane emissions from livestock can only reduce emissions by 30%, even as livestock-related emissions are likely to grow as the population grows. More RD&D, incentives, regulations and technical assistance across the economy will be needed to reduce these emissions and deploy available technologies.

This suite of strategies, some of which are already cost-competitive with more polluting alternatives, could take off with a pollution limit in place. The chart below, based on Evolved Energy’s data, shows how these strategies might intersect to help the U.S. reach a 100% clean economy (although it’s important to note that the Evolved analysis only considered energy-related CO­2 emissions).

(Click to Enlarge) *With electrification, there will be less direct use of fossil fuel, but the fuels that remain will tend to be more energy and carbon intensive **Includes negative emissions from biomass, increased sequestration in natural sinks, and negative emissions technologies +Some of the savings attributed to EE could also be attributed to electrification, as many electric technologies use less energy to provide the same service compared to fossil fuel burning alternatives

The contributions of each of the strategies in the figure should be considered rough orders of magnitude rather than precise estimates. There are many different ways to project the potential emissions reductions from each strategy, and each strategy also interacts and influences the others. For example, the extent to which expanded electrification leads to emissions reductions depends heavily on how clean the electricity sector becomes. The important thing to note is that we will have to make dramatic progress in each of these areas in order to achieve a 100% clean economy.

We can also see that even as overall emissions decline, there are forces pushing some sources of emissions up: Historically, as economic growth increased, so did energy consumption and emissions. While there’s recent evidence this relationship may be growing weaker, in general, higher GDP is associated with more energy demand. And while we expect to electrify a lot of the economy, not all equipment can be easily electrified, especially those that require the most energy, like airplanes and some industrial processes that require extremely high temperatures. As a result, the remaining fuels that are not replaced with electricity are more carbon intensive than the average of all of the fuels used today. So while there’s less direct use of fossil fuels, what’s left may be more carbon intensive.

At the big picture level, a 100% clean economy will be vastly more efficient, more reliant on clean electricity, and will deploy technologies and practices that capture and store at least as many emissions as we produce. Let’s go deeper and explore how a 100% clean economy might transform specific sectors:

  • In commercial and residential buildings, much of the energy needed for space and water heating and cooking will come from electricity. This will require next-generation appliance standards, more ambitious building codes, and incentives to adopt efficient electric technologies like electric heat pumps. Maximizing energy efficiency in new buildings will be essential: many of the buildings built today will still be standing in 2050.
  • Increased electrification will also be necessary in the industrial sector, although many industrial processes will be hard to electrify. Fuel switching to alternative low- or no-carbon sources like hydrogen or sustainable biofuels, as well as energy and material efficiency – making less resource-intensive products – can also significantly reduce industrial sector emissions. Finally, many industrial processes are good candidates for carbon capture and storage technologies that capture carbon emissions to be stored underground or put to productive use.
  • Electrification and efficiency will drive a lot of the transportation sector emission reductions. The Evolved analysis assumes that electric vehicles and other zero carbon alternatives like fuel cells make up nearly 100% of new vehicle sales by the end of the 2030s, up from only a few percent today. This will require expanded incentives for electric vehicles coupled with stronger climate pollution standards for cars and trucks (like the ones the Trump Administration is trying to roll back).

Deep decarbonization studies also often rely on biofuels as a large source of transportation emissions reductions, although measuring the full emissions footprint of biofuels is challenging and controversial.  What we do know is that, for applications such as jet fuel, electrification is unlikely, and therefore deployment of verifiably sustainable biofuels could play an important role in getting to 100% clean.

Taken together, transitioning to a 100% clean economy by midcentury will require an unprecedented transformation of our economy. Understanding the core elements of a 100% clean economy can help us design policies to accelerate the needed transition to a more efficient economy that relies more heavily on clean electricity and low carbon fuels, and which reduces as much climate pollution as it produces.

The good news is there are signs of progress. Several pieces of federal climate legislation have been introduced by members of both parties that would begin to put us on the right path. While a 100% clean economy ultimately requires that Congress enact legislation to drive down climate pollution, innovation is also an important piece of the climate puzzle, and it currently enjoys bipartisan support in Congress. And states across the country are already taking action.

100% clean is 100% achievable: now we need to build the political will to make it a reality.
