Alternatives like engineered porous liquids could offer better
options for carbon capture, a technology which may be essential to bridge the gap between increasing emissions of global warming gases and commitments to adopt alternative energy solutions to reduce these climate changing emissions.
These reports inevitably stray a little bit into policy areas, but they do a quite valuable job in summarizing things like technical
options for carbon capture and sequestration, and of evaluating methodologies for policy decisions.
Not exact matches
The most promising of these
options include renewable sources of a variety of types, advanced fossil - fuel technologies that can
capture and sequester
carbon, and hydrogen - powered fuel cells
for vehicle propulsion and dispersed electricity generation.
Other higher - tech
options include using chemicals to absorb CO2 from the air, or burning plants
for energy and
capturing the CO2 that would otherwise be released, then storing it permanently deep below the ground, called bioenergy with
carbon capture and storage (BECCS).

While the Climate Change pundits agree that energy efficiency and renewables are in the long term, «the most sustainable solutions both
for security of supply and climate,» they argue that «global greenhouse gas emissions can not be reduced by at least 50 % by 2050, as they need to be, if we do not also use other
options such as
carbon capture and storage.»

carbon capture on land, during glacials.
Under the «new policies» scenario, the IEA says gas has a «very bright» outlook
for the gas industry, particularly countries like Australia, the US and China, which have a lot of it to exploit, although the game plan relies on
carbon capture being a serious and cost effective
option by the mid 2020s.
This will be essential to distinguish sustainable and ethical
options from the rest:
for example, within BECCS, forest plantations that displace indigenous peoples to supply biomass power are unethical, yet adding
carbon capture to existing pulp and paper production might be sustainable.
Options for mitigation of GHG emissions from industry fall into the following categories: energy efficiency, emissions efficiency (including fuel and feedstock switching,
carbon dioxide
capture and storage), material efficiency (
for example through reduced yield losses in production), re ‐ use of materials and recycling of products, more intensive and longer use of products, and reduced demand
for product services.
