    Say you are a maker of computer graphics cards, under pressure from investors questioning your green credentials. You know what to do. You email your various departments, asking them to tally up their carbon emissions and the energy they consume. Simple enough. You write a report pledging a more sustainable future, in which your trucks are electrified and solar panels adorn your offices.

    Good start, your investors say. But what about the mines that produced the tantalum or palladium in your transistors? Or the silicon wafers that arrived via a lengthy supply chain? And what of when your product is shipped to customers, who install it in a laptop or run it 24/7 inside a data center to train an AI model like GPT-4 (or 5) ? Eventually it will be discarded as trash or recycled. Chase down every ton of carbon and the emissions a company creates are many times times higher than it first seemed.

    Fastening the seat belt buckle and knowing your flight is on its way to its destination: Nice. Getting stuck in a tarmac traffic jam and waiting for your flight to take off: Not so nice. Turns out the wait is also not nice for the planet.

    Flying in an airplane is already one of the most emissions-intensive things you can do. Globally, aviation produced over 1 billion tons of carbon emissions in 2019 , more than 2 percent of all human-generated emissions—more than either shipping or rail. Aircraft engines also emit nitrogen oxides, soot particles, and water vapor, which also contribute to warming the planet.

      Trump admin. finally kills off Obama-era rule limiting methane emissions

    The Environmental Protection Agency this week finalized a rule that kills off Obama-era limitations on how much methane, a potent greenhouse gas, oil and natural gas producers are allowed to emit into the atmosphere—even though industry leaders didn't want the changes.

    The changes to the rules, known as the New Source Performance Standards (NSPS), remove some segments of the industry from being covered under the existing standards at all, and these changes also lift the methane caps on other segments, the EPA announced on Thursday.

    The oil and gas industry basically splits into three big buckets of activity: upstream, meaning the actual drilling for oil or gas; midstream, which is the world of storage and pipelines; and downstream, that last mile where products are refined and sold. The current changes apply to the downstream and midstream segments, as the EPA broke down in a graphic ( PDF ).
