Big Food and greenhouse gas emissions

By Leave a Comment

The global food system is responsible for as much as 40% of human-generated greenhouse gas emissions. The investor advocacy group Ceres has tracked whether the 50 largest North American food and agriculture companies have set targets to lower their emissions and whether doing so has actually resulted in lower emissions.

The emissions from food and agriculture companies are grouped into three so-called scopes.  Scope 1 are emissions from a company’s direct operations.  Scope 2 are emissions from its energy use.  Scope 3 are emissions from a company’s supply chain:  from the farmers who grow crops, raise cattle, and otherwise provide necessary items for a company’s final products.  In the food industry, the scope 3 category is responsible for about 90% of overall emissions.

Of the 50 food companies studied, 23 reduced their scope 1 and scope 2 emissions over the past 2 years, but only 12 reduced their scope 3 emissions.  Companies have more control over their scope 1 and scope 2 emissions. 

Reducing scope 3 emissions is more difficult.  And most companies haven’t set scope 3 reduction targets. 

The findings of the study suggest that reducing scope 3 emissions is especially difficult for companies whose supply chains are linked to carbon-intensive commodities, like meat, or crops linked to deforestation or land-use change, both of which result in increased emissions.

In March, the Securities and Exchange Commission finalized rules requiring companies to disclose their climate risk to regulators, increasing the visibility of the food industry emissions issue.

The end of the Chevron deference

By Leave a Comment

 At the end of June, the US Supreme Court upended 40 years of legal precedent in a ruling that sharply limited the regulatory authority of federal agencies.  The so-called Chevron Deference doctrine stated that when a legislative delegation to an administrative agency on a particular issue or question was not explicit but rather implicit, a court may not substitute its own interpretation of the statue for a reasonable interpretation made by the administrative agency.

Under the new ruling, courts will have more power to interpret these statutes.  Environmentalists fear that this decision could lead to hundreds of rules being weakened or even eliminated, particularly Environmental Protection Agency limits on air and water pollution, regulations on toxic chemicals, and policies to tackle climate change.

Conservative political organizations have been pushing for decades to roll back the government’s regulatory powers.  The new ruling creates a massive opportunity for environmental regulations to be challenged, considering the proliferation of increasingly activist, right-leaning courts.  In particular, climate regulations under the Clean Air Act are more susceptible to judicial reversal.  The ruling shifts the power from the agencies to the courts.

The danger of this decision is that more Americans will suffer from the worse effects of climate change, air pollution, and other environmental harms that current government regulation protect against.  Any time that the Court makes it harder for the government to regulate and easier for businesses to challenge regulations, it makes it more likely that industries will injure the public and the planet in search of profits.  This is basic economics in action.

Blue Carbon Credits | Earth Wise

By Leave a Comment

Carbon credits have been around since the late 1990s.  The idea is to offset carbon emissions from some carbon emitting activity – anything from a wedding in California to a factory operating in Minnesota – by buying carbon credits earned from a carbon-absorbing activity, such as planting trees in the Amazon.

Blue carbon credits are credits earned by increasing the carbon stored in coastal and marine ecosystems. Coastal ecosystems such as mangroves, tidal marshes, and seagrass meadows in fact sequester and store more carbon per unit area than terrestrial forests and are increasingly being recognized for their important role in mitigating climate change. 

Blue carbon credit awards have to date been relatively few and far between and have mostly been granted for mangrove restoration efforts.  But mangrove projects are now ramping up dramatically in scope.  Scientists are working hard to analyze the amount of carbon in other ecosystem types – seagrasses, salt marshes, seaweeds, and seafloor sediments – so that these systems can also enter the carbon credit market.

Over the past 20 years, conservation scientists have spread over 70 million seeds in the bays of Virginia to restore over 9,000 acres of seagrass meadows that were devastated by disease in the 1930s.  The restored meadows are absorbing nearly half a ton of CO2 per acre. 

The rules to allow for blue carbon credits are recent and evolving, which is a big deal. The market may currently be small, but it is growing exponentially.  But as important as carbon credits are, it is still paramount to decarbonize before turning to offsets for existing emissions.

Restoring Environmental Rules Will Take Time | Earth Wise

By Leave a Comment

Over the previous four years, the Trump administration weakened or rolled back more than 100 rules and regulations on air, water, public lands, endangered species, and climate change.  The Biden administration has vowed to review these changes and restore the environmental protections that were removed or weakened.

The process of restoring environmental protections generally fall into a few broad categories.  Some changes can happen by executive order.  The President can cancel individual fossil fuel infrastructure projects or reinstate federal protection of specific places.  On his first day in office, President Biden rescinded the construction permit for the Keystone XL pipeline.

The President is also expected to restore federal protection to the Bears Ears and Grand Staircase-Escalante national monuments in Utah, which the Trump administration opened up to mining, logging, and drilling.

However, it could take two years or more to restore Obama-era climate change regulations including limits on emissions, rules on industrial emissions of toxic pollutants such as mercury, and protections on wetlands and waterways.

Reinstating comprehensive regulations on air, water, and climate pollution will take years because the Trump administration, rather than eliminating rules entirely, often replaced them with weaker regulations.  Replacing the weak regulations cannot just happen by executive order.  The process involves scientific and economic analysis, and that takes time.

After four years of shrinking budget and shrinking staff, the Environmental Protection Agency has a lot of catching up to do and will need to prioritize its actions in order to deal with the most damaging consequences of the previous administration.

Hyping Electric Cars | Earth Wise

By Leave a Comment

During this year’s Super Bowl, at least three car companies – GM, Porsche, and Audi – ran commercials for plug-in cars.  This is a sign that automakers are ramping up their efforts to persuade the public that electric cars really are the future.

The auto industry is investing billions of dollars to develop electric vehicles, spurred by stricter emissions rules in places like California and concerns about climate change.  In fact, more than 100 new plug-in models are expected to become available in the United States over the next five years.

In Europe, electric cars are increasingly popular.  Norwegians, for example, buy more electric cars than gas cars.  And several European countries have banned the sale of gas cars starting in 2025.

But in the US, enthusiasm for electric cars has been slow to build.  Automakers sold fewer than 330,00 electric vehicles in the US in 2019 and more than half of those were from Tesla, which actually does not even advertise its vehicles.

The auto industry spent nearly $9 billion in national and local advertising in the US last year, but less than half a percent of that went toward promoting electric vehicles.

A big part of the problem is that car dealers are not very enthusiastic about selling electric cars, which require far less maintenance than conventional cars and have far fewer costly replacement parts to sell.   As a result, the industry’s efforts to speed the transition to electric cars has been ambivalent at best.

World-wide, Tesla has sold about a million cars, mostly in the past 4 years, so there is clearly a growing demand for electric vehicles.  It is up to the rest of the industry to create demand for the new cars they have committed to produce.

A First In The Climate Change Fight | Earth Wise

By Leave a Comment

Under a new initiative, builders in New Jersey will have to take climate change into account in order to win government approval for projects.  New Jersey is the first state in the United States to enact such a requirement, which will leverage land-use rules to control what and where developers can build, and limit the volume of pollution. 

Through executive order, New Jersey Governor Phil Murphy will require the state Department of Environmental Protection to draft new building regulations.  The changes, to be adopted by January 2022, do not require legislative approval, but could face political and legal challenges. 

Climate change is expected to have a significant impact on New Jersey and its 130 miles of coastline.  According to a recent study from Rutgers University, the sea level along the New Jersey coast rose 1.5 feet since 1911, which was more than twice as much as the global average. The sea level is expected to rise by as much as another foot by 2030.  At the same time, some coastal areas of New Jersey are gradually sinking.

The initiative by New Jersey comes on the heels of a Trump administration proposal which would allow federal agencies to not take climate change into account when evaluating infrastructure projects. The federal changes are geared towards speeding up approvals for highway construction, pipelines, oil and gas leases, and other major infrastructure projects.   

In the absence of anything resembling leadership on climate change from the federal government, it remains for states like New Jersey to continue to press ahead.  In addition to the new building initiative, New Jersey also plans to produce 100% clean energy by 2050.

A Carbon Loophole

By Leave a Comment

Many power plants in Europe and elsewhere are replacing coal with wood.  For example, the Drax Power Station in Britain was its largest coal-burning plant and is now using wood pellets shipped from the southern U.S. in its boilers.    According to the carbon accounting rules at the EU and elsewhere, the process is considered to be “carbon neutral.”   But is it?

The idea is that new trees are being planted in the forests where the trees are cut to be burned in power plants.  So, there is carbon neutrality.  In principle.

European countries have embarked on a massive effort to switch to generating power from renewable energy.  While there has indeed been major growth in wind and solar power in the 28 countries of the European Union, much of the new “green” power has come from burning wood in converted coal power stations.

A group of 200 scientists wrote to the EU last September insisting that bioenergy from forest biomass is not carbon neutral and that there must be tighter rules to protect forests and their carbon.  Wood burning has become a loophole in controlling carbon emissions.

There are problems with the claims of carbon neutrality.  There is no way to know whether enough new trees are actually being planted to replace those being burned.  And then there is the time lag for tree replacement.  Trees don’t grow overnight.  There are also the carbon emissions associated with harvesting, processing and transporting wood.

There are most certainly ways in which burning biomass can be carbon neutral and can represent real progress over the use of fossil fuels.  But caution must be taken to avoid exploiting loopholes in current climate rules that might actually result in increased carbon emissions.

New Rules For Ocean Conservation

By Leave a Comment

In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas.  That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions.  The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.
