Postcard from California: Are corporate “climate offsets” just greenwashing?

By Bill Walker

Apple touts the newest model of the Apple Watch as its first “carbon neutral” product – made with “100% clean energy” and “recycled and renewable materials” and shipped by “lower-carbon modes” instead of by air. But a close look at the watch’s environmental specs shows that reducing emissions of greenhouse gases in its manufacturing and supply chain only goes so far.

More than one-fifth of the claimed savings in emissions are attributed to Apple’s purchase of so-called climate offsets, including shares in a project to plant eucalyptus timber plantations in eastern Paraguay, far from its Silicon Valley headquarters or its factories in China.

The project’s backers say the climate offsets it is buying reflect a reduction in eastern Paraguay’s emissions from cattle ranching, a leading source of planet-heating methane. But human rights groups say the scheme is driving peasant farmers from their land for little actual climate gain as most of the newly planted trees will be harvested quickly for consumer products.

Apple is but one of many corporate giants that has pledged to cut its company-wide emissions to “net zero” by 2030, joined by Google, Disney, Netflix and many more brands.

Even ExxonMobil, Shell, BP, and Chevron – the multinational oil companies that are the biggest emitters of greenhouse gases in the last decade – say they will be net zero by 2050.

According to the nonprofit Net Zero Tracker, more than 1,000 of the world’s largest companies have publicly declared goals of net zero by midcentury or before.

To get there, most plan to claim their purchases of climate offsets, also known as carbon credits, as emissions reductions. Through exchanges called verifiers or certifiers, companies buy, sell and trade shares in schemes that promise to reduce emissions, supposedly offsetting the climate pollution the companies can’t, or won’t, eliminate from their own operations.

Postcard from California: State emits more of an obscure climate-heating gas than the entire rest of the US

By Bill Walker

Among US states, California is a leader in efforts to cut emissions of the greenhouse gases that fuel the climate crisis. But just three counties in Southern California emit far more of one little-known greenhouse gas than all other US states combined.

Blame termites – and the tragic, too-frequent mistake of replacing one environmentally harmful chemical with another that turns out to be just as bad.

Sulfuryl fluoride is a fumigant pesticide first made by Dow Chemical Co., marketed since 1959 as Vikane. To kill western drywood termites, pest control companies cover infested houses with tents and then pump in Vikane. Houses tented for fumigation are a common sight in Southern California, where warm, dry weather leaves wooden buildings highly susceptible to infestations of the hard-to-exterminate species.

The colorless, odorless, highly neurotoxic gas that kills termites is also a danger to humans. That’s why Vikane must be spiked with another toxic pesticide gas called chloropicrin, which has an intensely irritating smell that is meant to warn people against entering a house until the fumigant has dispersed in 24 to 72 hours.

California Department of Pesticide Regulation (DPR) records show that between 1992 and 2017, at least 16 Californians died from sulfuryl fluoride poisoning after going inside fumigated houses too soon. In the same period DPR recorded more than 200 cases of human exposure that caused breathing problems, dizziness, nausea, and other symptoms.

But the biggest problem with Vikane is that, when fumigation tents are removed and sulfuryl fluoride disperses into the atmosphere, it is a greenhouse gas much more powerful than carbon dioxide (CO2).

Postcard from California: “No one is safe” – state banning diesel trucks

By Bill Walker

Forty percent of all US imports of consumer goods come through the adjacent ports of Los Angeles and Long Beach. Most of the merchandise is initially trucked to one of thousands of distribution center warehouses in the Inland Empire of San Bernardino and Riverside counties, where it is sorted and packaged for delivery to American homes and stores.
