Carbon capture, storage and utilisation technologies: A critical analysis and comparison of their life cycle environmental impacts

Following my previous post I would like to bring readers attention to this paper taken from my RSS feed today 17/09/2016.

27 life cycle assessment studies reviewed of which 11 focus on CCS and 16 on CCU.
CCS reduces the GWP by 63–82% but increases some other life cycle impacts.
The GWP of CCS is significantly lower than that of CCU.
However, other environmental impacts from CCS are higher compared to CCU."

Our best shot at cooling the planet might be right under our feet Ref: Global Dev Professionals Network_The Guardian UK

Our best shot at cooling the planet might be right under our feet.- brought to us by the Global Development Professionals Network.

Global temperature record brocken:

"Every one of the past 14 months has broken the global temperature record. Ice cover in the Arctic sea just hit a new low, at 525,000 square miles less than normal. And apparently we’re not doing much to stop it: according to Professor Kevin Anderson, one of Britain’s leading climate scientists, we’ve already blown our chances of keeping global warming below the “safe” threshold of 1.5 degrees." quoted from the Guardian.

Global Temperature Targets and how to achieve them

"If we want to stay below the upper ceiling of 2 degrees, though, we still have a shot. But it’s going to take a monumental effort. Anderson and his colleagues estimate that in order to keep within this threshold, we need to start reducing emissions by a sobering 8%–10% per year, from now until we reach “net zero” in 2050. If that doesn’t sound difficult enough, here’s the clincher: efficiency improvements and clean energy technologies will only win us reductions of about 4% per year at most." 

Quick look

"Maybe our engineers are missing the point. The problem with geo-engineering is that it proceeds from the very same logic that got us into this mess in the first place: one that treats the land as something to be subdued, dominated and consumed. But the solution to climate change won’t be found in the latest schemes to bend our living planet to the will of man. Perhaps instead it lies in something much more down to earth – an ethic of care and healing, starting with the soils on which our existence depends.

Of course, regenerative farming doesn’t offer a permanent solution to the climate crisis; soils can only hold a finite amount of carbon. We still need to get off fossil fuels, and – most importantly – we have to kick our obsession with endless exponential growth and downsize our material economy to bring it back in tune with ecological cycles. But it might buy us some time to get our act together." ref The Guardian
Well known but quickly forgotten. 
"Feeding the world isn’t about higher yields; it’s about fairer distribution. We already grow enough food for 10 billion people. In any case, it can be argued that regenerative farming actually increases crop yields over the long term by enhancing soil fertility and improving resilience against drought and flooding. So as climate change makes farming more difficult, this may be our best bet for food security, too."

Quantification of contamination risk caused by radioisotopes released from the Fukushima Dai-ichi nuclear power plant is useful for excluding or reducing groundless rumors about food safety. Our new statistical approach made it possible to evaluate the risk for aquatic food and showed that the present contamination levels of radiocesiums are low overall. However, some freshwater species still have relatively high risks. We also suggest the necessity of refining data collection plans to reduce detection limits in the future, because a small number of precise measurements are more valuable than many measurements that are below detection limits.


Food contamination caused by radioisotopes released from the Fukushima Dai-ichi nuclear power plant is of great public concern. The contamination risk for food items should be estimated depending on the characteristics and geographic environments of each item. However, evaluating current and future risk for food items is generally difficult because of small sample sizes, high detection limits, and insufficient survey periods. We evaluated the risk for aquatic food items exceeding a threshold of the radioactive cesium in each species and location using a statistical model. Here we show that the overall contamination risk for aquatic food items is very low. Some freshwater biota, however, are still highly contaminated, particularly in Fukushima. Highly contaminated fish generally tend to have large body size and high trophic levels.

Global terrestrial vegetation plays a critical role in biogeochemical cycles and provides important ecosystem services. Vegetation has been altered by anthropogenic global change drivers including land-use change, altered disturbance regimes, invasive species, and climate change, for decades to centuries, or in some cases millennia. Vegetation responses to land use and disturbance can be more immediate than to climate change and can be long lasting. The effect of global warming on water balance may have a stronger influence than the direct effects of temperature on vegetation. Models deployed at multiple ecological scales, populations, communities, and landscapes will be required to forecast vegetation responses and feedbacks to accelerated global change.


Anthropogenic drivers of global change include rising atmospheric concentrations of carbon dioxide and other greenhouse gasses and resulting changes in the climate, as well as nitrogen deposition, biotic invasions, altered disturbance regimes, and land-use change. Predicting the effects of global change on terrestrial plant communities is crucial because of the ecosystem services vegetation provides, from climate regulation to forest products. In this paper, we present a framework for detecting vegetation changes and attributing them to global change drivers that incorporates multiple lines of evidence from spatially extensive monitoring networks, distributed experiments, remotely sensed data, and historical records. Based on a literature review, we summarize observed changes and then describe modeling tools that can forecast the impacts of multiple drivers on plant communities in an era of rapid change. Observed responses to changes in temperature, water, nutrients, land use, and disturbance show strong sensitivity of ecosystem productivity and plant population dynamics to water balance and long-lasting effects of disturbance on plant community dynamics. Persistent effects of land-use change and human-altered fire regimes on vegetation can overshadow or interact with climate change impacts. Models forecasting plant community responses to global change incorporate shifting ecological niches, population dynamics, species interactions, spatially explicit disturbance, ecosystem processes, and plant functional responses. Monitoring, experiments, and models evaluating multiple change drivers are needed to detect and predict vegetation changes in response to 21st century global change.
