From Mexico City to San Francisco: A multi-national perspective on water management

By Ana Lucía García Briones, Senior Specialist, CA Groundwater Program

On World Water Day, I am reminded of what brought me to the Environmental Defense Fund: a passion for working on market-based incentive programs to improve groundwater management in California, ultimately benefiting multiple, diverse communities.

Born and raised in Mexico City, I moved to San Francisco to work on drought-related problems in California. It has been a surreal experience, allowing me to help disproportionately im

pacted communities, many of which are poor Latino communities in the rural Central Valley, where most of the nation’s fruits and vegetables are grown. In this way, I feel a little bit closer to home.

Water security for all

Many people may not realize it, but only about 5 percent of usable water in California is visible; the rest is underground. With access to surface water curtailed because of a five-year drought, many of the state’s biggest water users – farms and cities – have relied on groundwater pumping as a last resort. This has drawn down aquifers to dangerously low levels, and has left some rural communities without any water at all. 

A new law passed in 2014 will require 127 groundwater basins in the state to come up with sustainable groundwater management plans by 2020 or 2022 (depending on how dire the conditions of the basin are). I am helping to give disadvantaged communities a voice in the process. Read More »

Let’s Stop Pitting In-Store vs. Online Shopping: Both Need to Up Their Sustainability

We all like clear-cut, simple, black and white answers. But the world, as you well know, is a really complex place. Yet despite this general acknowledgment of complexity, we still get caught-up in simplified debates: paper vs plastic; cloth vs disposable diapers; and now shopping online vs shopping at the store.

This is not a cage match. The fact of the matter is that both shopping online and shopping at stores are here to stay. And this is a good thing. We now have more choices. Citizens and companies can leverage these choices to minimize their environmental foot print.

Into the debate mindset, Simon Property Group released an assessment, Think Before You Click: Does Shopping Behavior Impact Sustainability? Simon is a leading real estate company that owns a number of malls. It also has been a host company for EDF Climate Corps.

The paper is a valuable because it sheds light on one way people shop: buying multiple items at once and combining the shopping trip with other activities. It concludes that — in the specific scenario Simon created — shopping at the store has a lower environmental impact.

To me, the conclusion is the least insightful aspect of the study. It is not surprising that a large owner of malls would choose a scenario that highlights the attributes of shopping at malls compared to shopping online. What is most insightful to me is the attributes that determine the environmental impact.

Global shopping cartDistance from a retail location, distance and method of online delivery, likelihood of returns, building energy use and packaging were all attributes that were examined in the Simon paper. These attributes were also the factors used in the most authoritative research I have yet read on the topic, which came from the MIT Center for Transportation & Logistics. The Simon paper went one attribute further, though.

Key to the findings of the Simon paper was the fact that its scenario includes the purchase of four items. It also made the assumption that buying these online would result in four distinct deliveries. Given the diversity of items purchased, this certainly could be the case. It however does not need to be.

The fact is there are many opportunities to reduce the environmental impact associated with goods purchased online. There are also many opportunities to reduce the environmental impact associated with goods purchased at stores. It also must be noted that transportation and packaging are but two of the numerous aspects of product lifecycle impact.

What are these opportunities?

For companies that sell online, they can:

  1. Provide incentives for customers to choose less impactful delivery options. “Free” shipping is here to stay, of course. Companies could provide reward points or other inducements for customers to choose the four to five day option instead of the two-day or overnight.
  2. Provide incentives for customers to return more sparingly. As much as a third of online purchases are returned. The environmental impact associated with the returns was a significant factor in the Simon scenario and those examined by MIT. Again, there is an opportunity here for reward points or other inducements.
  3. Get serious about tackling excessive packaging. As the New York Times recently reported, “4 million tons of containerboard were produced in 2014 in the United States, with e-commerce companies among the fastest-growing users.” Let’s deal with this.

For companies that set-up physical stores:

  1. Invest in increasing public transportation options for your locations.
  2. Increase the energy efficiency of your operations. Upgrading lighting and HVAC systems are a good place to start. Join the many other retailers hosting EDF Climate Corps fellows to undertake this type of work.
  3. Explore on-sight generation of renewable energy. An apt example here is how Simon worked with EDF Climate Corps in 2015.

Both online and bricks and mortar retailers have ample opportunities to reduce the impact of the goods moving into their warehouses and stores. Retailers and their suppliers should:

  1. Get the most out of every move. Combine and adapt packaging to maximize cube utilization.  A fuller move is a greener, as demonstrated by Walmart, Kraft and others.
  2. Choose the most carbon-efficient transport mode. Ocean Spray Cranberries and many others are cutting carbon and costs with this approach.
  3. Collaborate with other freight shippers. Colgate, Kimberly Clark and CVS are showing the way here.

The EDF Green Freight Handbook is a solid resource for companies needed to get a start on these types of actions.

The world is complex, which is good news because this complexity gives us choices. I’m choosing to focus on how to manage these complexities to improve our environment and economy. I’d love to have you join me; the only requirement is to leave the online vs. in-store mind-set at the door.

Go Farther, Faster to Cut Truck Pollution

The U.S. has put in place well-designed policies to cut climate pollution, and, with adopted and proposed policies, the nation’s 2025 climate reduction goals are within reach.  However, we are not there yet, and important work remains.

Big trucks have a critical contribution to make in cutting emissions now and well into the future. Cost-effective technologies are available to significantly reduce fuel use. Conversely, if we don’t take common sense steps today to cut climate-destabilizing emissions from this sector, climate emissions are projected to rise by approximately 15 percent by 2040. This is particularly problematic when you consider that the nation must reduce carbon emissions by at least 83 percent below 2005 levels by 2050 to prevent severe, potentially catastrophic, levels of climate change. Without further action to cut emissions from heavy-trucks, the sector would consume nearly 40 percent of our national 2050 emissions budget – a level that is clearly not sustainable.

Pepsi truck

600-02056018

The good news is that there is much that can be done to reduce emissions from trucks while also saving money; this year we have a unique opportunity to get started. As EPA Administrator McCarthy recently noted, finalizing new greenhouse gas (GHG) standards for heavy-duty vehicles is a priority in 2016.

Given the combination of environmental and economic benefits that strong GHG standards will provide, many leading companies have already shown public support. PepsiCo and Walmart – two of the largest trucking fleets in the U.S. — support strong standards. General Mills, Campbell’s Soup, IKEA and many other companies that rely on trucking support strong standards. Innovative manufacturers support strong standards.

So, where do we go from here?

The draft proposal issued jointly by the Environmental Protection Agency (EPA) and the Department of Transportation (DOT) in June 2015 is a good step, particularly because it maintains a sound, enforceable structure of separate engine and vehicle standards. However, the proposal leaves significant emission reductions on the table, specifically in its engine standard.

The first generation of heavy truck fuel efficiency standards required engines to reduce fuel use and emissions by 6 percent from 2010 to 2017, or roughly 1 percent per year. The current draft would require reductions of only 4.2 percent from 2017 through 2030. Nearly all of this progress occurs between 2021 and 2024. Between 2025 and 2030 these standards increase by only 0.5 percent.  The hill we need to climb to achieve our 2050 emissions goals is steep enough without losing critical time to such nominal progress.

We can do more.

  • Finalizing stronger standards today will deliver more than just near-term emissions reductions. Trucks are long-lived assets. Some trucks manufactured in 2025 will still be on the road well into the middle of this century. The trucks we put on the road in 2030 will impact our ability to meet 2050 targets – and to avoid catastrophic climate change.
  • Stronger standards also enable a virtuous cycle of improvement. A higher bar for these next standards will drive additional investments in research and development and expedite market entry of the next generation of solutions. This, in turn, drives the innovation we will need to enable this sector to contribute to achieving our 2050 targets. All while creating an annual economic benefit of $50 billion dollars.

The savings potential we are seeing now is only the tip of the iceberg. As an executive with the Volvo Group – a leading global producer of heavy-trucks — recently highlighted, “there are no real limits” to our technical ability to reduce greenhouse gas emissions from trucks.  Our limitations are societal choices.

When it comes to trucks, we know that much greater emission savings than have been proposed are eminently reasonable. We know more protective standards are readily within reach – one of the largest truck makers created a truck that gets 12.2 MPG and another leading manufacturer and engine company teamed-up to create a 10.7 MPG truck.

These breakthroughs and others have come through the Department of Energy’s SuperTruck program — a leading public-private partnership that has delivered impressive results over the past decade and is investing another $80 million to develop more fuel saving solutions. Included among its current research investments are a medium-duty plug-in hybrid vehicle powertrain that reduces fuel consumption by 50 percent; a class 6 plug in hybrid delivery truck that reduces fuel consumption by 50 percent; and a class 6 delivery truck with a scalable, innovative, lightweight, low-cost, and commercially-viable plug-in electric drive system that improves fuel economy by 100 percent.

Here’s hoping the EPA and DOT, recognizing the clear potential of existing and emerging technology, will finalize the protective standards we need to cut truck pollution farther, faster, strengthen our economy and achieve U.S. climate goals.

Climate denial has no place in the court

(This post was co-written by EDF’s Martha Roberts and Ilissa Ocko)

As federal courts consider the legal merits of the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan — America’s first-ever national limits on carbon pollution from power plants – we find ourselves in a situation that might have felt familiar to Galileo, who was hauled before authorities for having the temerity to make conclusions based on science.

Three hundred seventy-four years after Galileo, flat-earth Clean Power Plan opponents are using the court’s time to challenge EPA’s rock solid conclusions about the scientific realities of climate change. They’re using misinformation and misrepresentation in an attempt to block EPA’s flexible and efficient approach to reducing the carbon pollution that is causing so much costly damage to our society.

Yes, they’re still doing that in 2016.

The Usual Suspects

The latest assault takes the form of an amicus, or “friend of the court,” brief that was submitted last week to the U.S. Court of Appeals for the D.C. Circuit. It deploys selective reasoning and misleading arguments in an attempt to discredit evidence of climate change.

It’s numbingly familiar, but not surprising, to see Fred Singer’s name on the brief. A former tobacco industry mouthpiece, he’s been a mainstay for years in what’s been called the “parallel universe” of climate denial conferences.

It’s also no surprise that Peabody Energy — the world’s largest privately owned coal company — contested EPA’s rock solid climate science in an earlier submission to the court, given the company’s history of obfuscating the impacts of climate change in order to protect its profits.

The Real Motivation

This effort isn’t about debating science. It’s about using misinformation to obstruct climate progress. This attack is part of a longstanding effort to undermine EPA’s common sense solutions to limit harmful greenhouse gas pollution at all – despite that fact that the Supreme Court has repeatedly ruled that the Clean Air Act requires EPA to address climate pollution. Coal companies and their hired allies have relentlessly attacked EPA’s safeguards to protect human health and the environment from climate pollution.

Junk Science Amicus Brief

This junk science submission, authored by Singer and others, claims to be based on “real world empirical temperature data” (amicus brief, page 15) – but in truth it’s deceptively unscientific, cherry-picking dates and locations in an effort to rebut overwhelming evidence of rising surface temperatures.

Two obvious flaws demonstrate the problematic reasoning employed by the brief.

First, the authors contend that globally averaged surface temperature has not increased because:

The decade of the 1930s still has the most currently held high-temperature records for States within the United States. (amicus brief, page 31)

This point suffers from cherry picking data that seems to support their phony argument. Drawing a comparison between a long term globally averaged temperature trend (i.e., as related to anthropogenic climate change) and summertime regional temperature spikes in a select portion of the U.S. is inherently misleading (see Figure 1 below). The U.S. covers only two percent of the global surface area, and the Great Plains far less. Arguing that a small regional temperature anomaly undermines for the global temperature trend is scientifically untenable.

Figure 1: How Cherry-Picked Data Misrepresents the Larger Picture

Source: The U.S. Global Historical Climatology Network Dataset

The second flaw is an egregious error with respect to defining a linear trend. The authors break the temperature time series in half and display two distinct trend lines separated by a large step increase, as opposed to the scientifically appropriate approach of employing the entire time series to define a trend.

Figure 2. The Amicus Brief’s Broken Time Trend Global Average Temperature Anomalies

(amicus brief, page 7)

They do this to hide the trend. It’s a classic strategy used by the climate denial community to deny trends, known as the “escalator” (see Figure 3 below).

The authors argue that the absence of a trend in the latter portion of the record indicates a lack of evidence for an anthropogenic climate change signal during this time. However, their starting point for the latter half is during the 1997-1998 El Nino, one of the strongest such events on record. Given that El Nino has a significant warming influence on a given year’s global temperature, starting at this point in the record introduces a strong temperature bias — i.e. the authors purposely choose a starting point with an extremely high temperature in order to create the appearance of a plateau in the years that follow.

It’s a bit like beginning a chart of Barry Bonds’ home runs per season in 2001, when he hit 73. The authors fail to disclose that the globally averaged temperature exceeded the 1990’s average in every year of the first decade of the 21st century and that both 2014 and 2015 broke records as the hottest years ever recorded — further confirming their selection bias.

The brief also attempts to reject EPA’s conclusion that the atmosphere in the tropics warms faster than the surface as a response to rising carbon dioxide levels.

The brief presents data from only a single location in an attempt to rebut this conclusion — the tropical central and eastern Pacific Ocean, an area home to the El Nino Southern Oscillation (ENSO), the largest mode of natural interannual climate variability on the planet.

Using only one region (and in this case a single idiosyncratic point) to represent the entire global tropics is highly misleading and scientifically inappropriate. The data manifestly suffer from selection bias and are not representative of the full population of tropical climate data.

Indeed, the temperature time series shown in their analysis correlate extremely well with recently observed El Nino and La Nina events — suggesting that their index is simply a proxy for the El Nino/La Nina signal. Extracting a trend from an area with extremely large natural variability is inherently tenuous, because the large background variability swamps our ability to observe any other data trends.

Unfortunately, this is not the first time opponents have inaccurately distorted climate data in this case.

Earlier in this same crucial case, Peabody represented to the court that EPA’s claims of climate harms “substantially outrun the available evidence.” (brief, page 7 footnotes)

Peabody’s efforts to justify these misleading allegations misrepresent scientific understanding of climate science in several major respects. Two core inconsistencies, among several, include:

  • Peabody’s biased assertion of hiatus in warming since 1998 — as mentioned earlier, beginning a trendline in 1998, an exceptionally warm year due to an unusually strong El Nino, is nonsensical and irrelevant to the long-term trend. Further, surface air temperatures are certainly still increasing. The 2000s were warmer than the 1990s, 2015 smashed all previous surface air temperature records, and heat uptake in the ocean has doubled over the last 20 years.
  • Flawed reasoning that increasing Antarctic sea ice disproves climate change — Antarctic sea ice is influenced by differences in fresh water supply and circulation in the Southern Ocean. Land ice that has taken thousands of years to accumulate in Antarctica is melting at a rapid rate due to warmer temperatures, changing the chemistry of the water and likely preventing the buildup of sea ice. Peabody’s submission ignored and omitted this crucial context.

Sadly, it’s not really news that Peabody is presenting misleading climate information. Peabody, the largest private-sector coal company in the world, was cited last fall by the New York Attorney General for violating investor protection laws by misrepresenting climate risk in its corporate filings. The Attorney General noted that Peabody “repeatedly denied in public financial filings to the Securities and Exchange Commission that it had the ability to predict the impact that potential regulation of climate change pollution would have on its business, even though Peabody and its consultants actually made projections that such regulation would have severe impacts on the company.”

The Sun Belongs to Everyone

By Jorge Madrid, Campaign Manager, Climate & Energy.
2016-03-03-1457029192-4192505-GRIDsolar1

I thought only supervillains like Mr. Burns or Supreme Leader Snoke from Star Wars were bold enough to try snuffing out the sun…I was wrong.

I’ve been writing about solar power and economic equity for eight years now and I still firmly believe the vision that drew me to this issue in the first place: solar and other forms of clean energy hold the potential to be a jobs and economic growth machine for communities who need it the most.

Back in 2008, I joined a collective movement of environmentalists, community and justice activists, and labor and faith groups who coalesced around a vision for the “green collar economy.” The idea of this movement was to fight climate change while also lifting people out of poverty and jails, and helping them transition into promising careers in growing industries.

Since then I’ve seen many great strides in the creation of a clean energy economy that employs hundreds of thousands with well-paying and accessible jobs, propelled by smart policy, innovation, and upstart private and public sector players, all making meaningful investments in communities. Rooftop solar in particular has begun to challenge the status quo by turning people’s homes into mini power plants, cutting into dirty power and the monopoly-dominated, electric grid.

Yet, despite this progress and opportunity, some states – fueled by short-sighted officials, fear-mongering, and the threat of declining profits for big business utilities – want to shut it all down. Read More »

3 reasons the Zika outbreak may be linked to climate change

The regions that the Zika virus outbreak has struck hardest, such as Brazil and Colombia, also happen to be areas that are currently plagued by hotter-than-usual temperatures.

So is there a connection?

The ways that virus-carrying mosquitoes change their behavior with warmer temperatures may, in fact, point to a link between the Zika outbreak and climate change like the one that exists with malaria, Lyme Disease and other ills.

While it’s important to remember that it’s probably a combination of reasons for the current Zika virus outbreak – including movement of people and available breeding grounds – there are three ways in particular that warmer weather may be contributing to the crisis:

graphic_v3 (2)

1. Hotter temperatures make mosquitoes hungrier

Female mosquitoes require blood meals for reproduction. Along with many cold-blooded animals, mosquitoes feed more frequently with higher temperatures. The more they eat, the likelier they are to get infected and spread the disease.

2. Warm air incubates the virus faster

A virus must incubate inside a mosquito before the mosquito becomes infectious. That takes about 10 days, roughly a mosquito’s lifespan, so the mosquito will often die before it can spread the disease.

But hotter temperatures speed up the incubation process in the cold-blooded mosquito, because the virus can replicate faster. This means that the mosquito will be alive longer while infectious, thus having more time to transmit the disease.

3. Mosquito territory expands as the climate warms

Mosquitoes flourish in warm climates, restricting their range based on temperature. But with climate change, plants and animals are moving northward and upward, and we know mosquitoes do the same as new areas become warmer and a suitable habitat.

As mosquitoes expand their range, they can introduce diseases to populations that otherwise would have been safely out of reach. The distribution of the Zika-carrying mosquito, in particular, has wildly increased over the past few decades, which have also been the hottest decade on Earth in more than 1,000 years.

In fact, the current epidemic took off in 2015, the hottest year in South America and globally since record-keeping began 136 years ago.

The links between mosquitoes and temperature are scientifically clear, and it’s possible that climate change may now be playing a role in the spread of the Zika virus, a disease suspected of causing serious birth defects.

To know for sure, and to help nations deal with the outbreak, more research is needed to tease out the specific causes of this global catastrophe.
