Fossil fuel companies impose more in climate costs than they make in profits

Climate change impacts exceed fossil fuel profits.

Stephane Bilodeau's curator insight, July 26, 2015 8:09 AM

"There's been a lot of work recently trying to quantify carbon risk. A new contribution to that conversation was just released by Chris Hope and colleagues at the University of Cambridge Judge Business School: "Quantifying the implicit climate subsidy received by leading fossil fuel companies." It attempts to put a number on the carbon risk facing the world's top 20 fossil fuel companies, the ones most directly vulnerable to a price on carbon. The results suggest that those companies are in a perilous situation.

(...)

The results are pretty startling. To wit: "For all companies and all years, the economic cost to society of their CO2 emissions was greater than their after‐tax profit, with the single exception of Exxon Mobil in 2008" (my emphasis). In other words, if these fossil fuel companies had to pay the full cost of the carbon emissions produced by their products, none of them would be profitable.

 

It's even worse for pure coal companies, for which "the economic cost to society exceeds total revenue in all years, with this cost varying between nearly $2 and nearly $9 per $1 of revenue." Total revenue, Hope and colleagues note, represents "employment, taxes, supply purchases, and indirect employment" — everything that coal companies contribute to the economy. It turns out the costs they impose through carbon emissions are larger than all those contributions combined. (For oil and gas companies, carbon costs generally range from 10 to 50 percent of total revenue.)"

Thermodynamic complexity of carbon capture in alkylamine-functionalized metal–organic frameworks

Thermodynamic complexity of carbon capture in alkylamine-functionalized metal–organic frameworks | Carbon Dioxide | Scoop.it
For coordinatively unsaturated metal–organic frameworks (MOFs), the metal centers can be functionalized as CO2 capture/storage adsorbents by grafting species having specific active groups. We report direct measurement of enthalpy of adsorption of CO2 on an alkylamine-appended MOF, mmen-Mg2(dobpdc) employing

A zeolite family with expanding structural complexity and embedded isoreticular structures

A zeolite family with expanding structural complexity and embedded isoreticular structures | Carbon Dioxide | Scoop.it
The prediction and synthesis of new crystal structures enable the targeted preparation of materials with desired properties. Among porous solids, this has been achieved for metal-organic frameworks, but not for the more widely applicable zeolites, where new materials are usually discovered using exploratory synthesis. Although millions of hypothetical zeolite structures have been proposed, not enough is known about their synthesis mechanism to allow any given structure to be prepared. Here we present an approach that combines structure solution with structure prediction, and inspires the targeted synthesis of new super-complex zeolites. We used electron diffraction to identify a family of related structures and to discover the structural /`coding/' within them. This allowed us to determine the complex, and previously unknown, structure of zeolite ZSM-25 (ref. 8), which has the largest unit-cell volume of all known zeolites (91,554 cubic angstroms) and demonstrates selective CO2 adsorption. By extending our method, we were able to predict other members of a family of increasingly complex, but structurally related, zeolites and to synthesize two more-complex zeolites in the family, PST-20 and PST-25, with much larger cell volumes (166,988 and 275,178 cubic angstroms, respectively) and similar selective adsorption properties. Members of this family have the same symmetry, but an expanding unit cell, and are related by hitherto unrecognized structural principles; we call these family members embedded isoreticular zeolite structures.

Why is the Amazon absorbing less carbon?

Why is the Amazon absorbing less carbon? | Carbon Dioxide | Scoop.it

So, the illegal lodging is not the only responsible for the decrease in CO2 absorption.

What happens with plant is as they are slow life being, in gardening whatever you do now will be seen in a couple of days, sometimes weeks. If you scale up the size of the garden you can also scale up the time frame of the consequences of your actions (that's is my humble guess)

ETI report: Insights into the future UK Bioenergy sector, gained using the ETI’s Bioenergy Value Chain Model (BVCM)

ETI report: Insights into the future UK Bioenergy sector, gained using the ETI’s Bioenergy Value Chain Model (BVCM) | Carbon Dioxide | Scoop.it
The Energy Technologies Institute is a UK based company formed from global industries - BP, Caterpillar, EDF, E.ON, Rolls-Royce and Shell - and the UK government. Government funding comes from the Department for Business Innovation and Skills (BIS), through the Technology Strategy Board (TSB) and EPSRC. Also works with the Department for Energy and Climate Change (DECC)
Alexandre Pépin's insight:

Biomass combined with CCS remains the only credible route to deliver negative emissions, and is the dominant method adopted by BVCM to meet GHG emission reduction targets.

Using biomass in conversion plants with CCS to generate either hydrogen or electricity is preferred to using biomass for transport biofuels and bio-methane
