Glossary of Greenhouse Gas Terms

Greenbuilding Law

With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.

A Dangerous Disruption

Legal Planet

Last week, MIT’s “Technology Review” reported that a small startup firm is proposing to spray reflective aerosols in the stratosphere commercially as a climate corrective. First, the cooling from the reflective materials they will inject, for which they are already selling carbon credits, charging $10 per gram of SO 2 released (!)

A Quick Science Refresher on Greenhouse Gas

Greenbuilding Law

With the federal government and state of Maryland each having announced within days of each other, the mandated disclosure of greenhouse gas (GHG) emissions, we have received, maybe not surprising, many calls in the last two weeks inquiring “what are GHGs?” Simply put, gases that trap heat in the atmosphere (.

Delayed harm and the politics of climate change, reconsidered

Legal Planet

The world is gathering soon in Glasgow to debate how to eliminate greenhouse gas emissions over the coming decades. Does the climate keep warming, stay the same, or even cool? But what happens when we achieve the goal of zero carbon dioxide emissions from human actions? Those kinds of impacts could provoke real political backlash.

Scientists strive for negative emissions

A Greener Life

Human activity adds more than 50 gigatons of carbon dioxide to the atmosphere each year. New Solid Carbon technology might be able to lock climate-warming carbon dioxide below ocean bedrock. What if scientists could turn back the clock on greenhouse-gas emissions – just a little? Basalt is a porous rock formed from cooling lava.

The Climate Overshoot Commission Releases its Report

Legal Planet

To give the Commission credit where due — and it is due in many places — on one point closely related to these projections, they were uncommonly and admirably frank: Noting the risks and the stark tradeoffs posed by aerosol pollution in the lower atmosphere. Current and coming advances in carbon-free technology will help, of course.

Environmental Groups Seek Investigation Into Enbridge Gas for False Advertising

Enviromental Defense

“Natural gas”, also known as methane gas or fracked fossil gas, is a potent greenhouse gas that pollutes the environment and causes climate change when it is burned and when it escapes into the atmosphere during extraction, production, and transportation. Enbridge should be made to stop deliberately misleading the public.”
