exists to inform people about the Climate Emergency and the need to reduce
atmospheric carbon dioxide (CO2 ) concentration to a safe and
sustainable level of about 300 ppm.
The fundamental position of 300.org is that “There must be a safe and sustainable existence for all peoples and all species on our warming-threatened Planet and this requires a rapid reduction of atmospheric carbon dioxide concentration to about 300 parts per million”.300.org urges the World to reduce atmospheric carbon dioxide concentration (CO2) to about 300 parts per million by volume (ppmv or ppm for short). In urging a target of an atmospheric CO2 concentration of 300 ppm, 300.org is informed by the advice of top world climate scientists as set out in carefully researched and documented presentations on this site (see Sitemap).
Basically we know what the problem is (man-made GHG pollution) and how to solve it. Fundamentally, as enunciated by 300.org, we need to reduce atmospheric CO2 concentration to about 300 ppm for a safe planet for all peoples and all species. .
To achieve 300 ppm CO2 and a safe planet for all peoples and all species we must achieve the following:
1. Change of societal philosophy to one of scientific risk management and biological sustainability with complete cessation of species extinctions and zero tolerance for lying.
2. Urgent reduction of atmospheric CO2 to a safe level of about 300 ppm as recommended by leading climate and biological scientists.
3. Rapid switch to the best non-carbon and renewable energy (solar, wind, geothermal, wave, tide and hydro options that are currently roughly the same market price as coal burning-based power) and to energy efficiency, public transport, needs-based production, re-afforestation and return of carbon as biochar to soils coupled with correspondingly rapid cessation of fossil fuel burning, deforestation, methanogenic livestock production and population growth.
We understand the problem and have the technological solutions (“Climate crisis facts and required actions”, Yarra Valley Climate Action Group: https://sites.google.com/site/yarravalleyclimateactiongroup/climate-crisis-facts-required-actions ) – the impending catastrophe simply does not have to happen. Are we going to be able to overcome the current political stasis and act before it is too late for Humanity and the Biosphere? Is it too late? Are we all doomed? (see “Are we doomed?”: https://sites.google.com/site/300orgsite/are-we-doomed ) .
Zero emissions is not enough – having achieved zero emissions we must reduce atmospheric CO2 back tho the pre-Industrial Revolution level of circa 300 ppm CO2 (indeed some experts suggest 260 ppm CO2 or 280 ppm CO2; see “300.org – return atmosphere CO2 to 300 ppm”: https://sites.google.com/site/300orgsite/300-org---return-atmosphere-co2-to-300-ppm) .
The draw-down from the current circa 400 ppm CO2 to circa 300 ppm CO2 can be achieved through generation of biochar (through anerobic pyrolysis of cellulosic agricultural and forestry waste over the next century; see Gideon Polya, “Forest biomass-derived Biochar can profitably reduce global warming and bushfire risk”, Yarra Valley Climate Action Group: https://sites.google.com/site/yarravalleyclimateactiongroup/forest-biomass-derived-biochar-can-profitably-reduce-global-warming-and-bushfire-risk .) and through Accelerated Weathering of Limestone (AWL, generation of bicarbonate through passing CO2 through calcium carbonate suspended in sea water; see Ken Caldeira and Greg H. Rau, “Accelerating carbonate dissolution to sequester carbon dioxide in the ocean: geochemical implications”, Geophysical Research Letters, 27 (2), 225-226 (2000): http://onlinelibrary.wiley.com/doi/10.1029/1999GL002364/abstract ; Greg H. Rau, Ken Caldeira, Kevin G. Knauss, Bill Downs and Hamid Sarv, “Enhanced carbonate dissolution as a means of capturing and sequestering carbon dioxide”, First National Conference on Carbon Sequestration, Washington DC, May 14-17, 2000: http://www.netl.doe.gov/publications/proceedings/01/carbon_seq/p24.pdf ; and G.H. Rau, “CO2 mitigation via capture and chemical conversion in seawater”, Environ Sci Technol 45:1088–1092, 2011: http://pubs.acs.org/doi/abs/10.1021/es102671x ) .
However these CO2 draw-down processes are expensive and from the perspective of young people (who will have to pay the mounting Carbon Debt) it is better to keep the fossil fuels in the ground . The essential argument is as follows (from Gideon Polya “Expert Witness Testimony to stop Gas-Fired Power Plant Installation”, Countercurrents, 14 June, 2013: http://www.countercurrents.org/polya140613.htm ):
(a). The current price of Australian thermal coal is about $90 per tonne or $90 per t C x (12t C/ 44 t CO2) = $24 per tonne of CO2 released on eventual combustion.
(b). However top climate scientists and biologists say that the atmospheric CO2 concentration must be rapidly returned from the present circa 400 ppm CO2 to about 300 ppm CO2 for a safe planet for all peoples and all species.
(c). Currently, apart from re-afforestation a major way of returning atmospheric CO2 back to 300 ppm CO2 is through producing biochar (carbon, charcoal, C) through anaerobic pyrolysis of cellulosic biomass waste in renewable energy-driven microwave furnaces at 400-700C (with existing agricultural and forestry waste this could achieve about 9 Gt per year, roughly the same as the annual industrial output).
(d). The cost of conversion of cellulosic waste to biochar in the US mid-West is about US$49-US$74 per tonne CO2 (US$210-US$303 per tonne CO2 in the UK ).
(e). Ergo, for every $1 received for coal by the coal industry our children, grandchildren and further generations will have to spend $2 to $3 at present prices converting the consequent CO2 back to biochar to save the Planet. One can accordingly similarly determine (for Australia) that the biochar production-related debt for future generations for every $1 received by the gas-based electricity industry will be about $0.6-$1.0 at present prices (these estimates must be multiplied by 4 for the cost of biochar production in the UK).
One must also consider the overall Carbon Debt to be paid by future generations (we are already paying for some of it through sea walls and flood and drought mitigation works). Thus climate economist Dr Chris Hope (from 100-Nobel-Laureate Cambridge University ( has estimated a damage-related Carbon Price of $150 per tonne CO2-e (see Dr Chris Hope, “How high should climate change taxes be?”, Working Paper Series, Judge Business School, University of Cambridge, 9.2011: http://www.jbs.cam.ac.uk/fileadmin/user_upload/research/workingpapers/wp1109.pdf ) . The essential arguments are as follows:
(a) There is 700- 750 GtC in atmosphere (mostly as CO2 and half due to historical fossil fuel combustion). To get the CO2 back to the pre-Industrial Revolution 300 ppm CO2 we must draw down about 700/2 = 350 Gt CO2. Thus will come at the cost of 350 Gt C x (3.67 Gt CO2/Gt C) x $150/t CO2) = $193 trillion.
(b) The latest upper estimate for annual global GHG pollution is 63.8 Gt CO2-e (see Robert Goodland and Jeff Anfang. “Livestock and climate change. What if the key actors in climate change are … cows, pigs and chickens?”, World Watch, November/December 2009: http://www.worldwatch.org/files/pdf/Livestock%20and%20Climate%20Change.pdf ) and accordingly the Carbon Debt is increasing at 63.8 Gt CO2-e x $150 /t CO2-e = $9.6 trillion per year.
(c) You can calculate your country’s Historical Carbon Debt and the annual increase in its Carbon Debt. Thus for climate criminal Australia (a world GHG polluter with an annual per capital Domestic plus Exported greenhouse gas pollution ) of about 2,000 Mt CO2-e annual pollution /24 million people = 83 t CO2-e per person per year as compared to Bangladesh’s 0.9 (see “Climate Genocide”: https://sites.google.com/site/climategenocide/ ) , its Historical Carbon Debt is 5.6 Gt C (see “Carbon Debt Carbon Credit”: https://sites.google.com/site/carbondebtcarboncredit/ ) that corresponds to 5.6 Gt C x (3.67 Gt CO2/Gt C) x $150/t CO2) = $3.1 trillion and this is increasing each year at 2 Gt C x (3.67 Gt CO2/Gt C) x $150/t CO2 = $1,100 billion (Domestioc plus Exported Carbon Debt) or 0.6 Gt C x (3.67 Gt CO2/Gt C) x $150/t CO2 = $330 billion per year. If we assume that it is only the 9.4 million Australians under 30 who will have to pay this Carbon Debt then their annual Carbon Debt is increasing at present at about $330,000 million/9.4 million = $35,106 per person i.e. about $35,000 per person.

Carbon Debt reflects the inescapable future cost in today's dollars of fixing the remorselessly increasing climate damage. Carbon Debt is the historical contribution of countries to the carbon pollution of the atmosphere and can be variously expressed as Gt CO2-e (gigatonnes or billions of tonnes of CO2-equivalent) or in dollar terms by applying a Carbon Price. Thus leading climate economist Dr Chris Hope from 90-Nobel-Laureate Cambridge University has estimated a damage-related Carbon Price in US dollars of $150 per tonne CO2-e (see Dr Chris Hope, “How high should climate change taxes be?”, Working Paper Series, Judge Business School, University of Cambridge, 9.2011: http://www.jbs.cam.ac.uk/fileadmin/user_upload/research/workingpapers/wp1109.pdf ).
The World added 350 Gt C (1285 Gt CO2) to the atmosphere in 1751-2006 (see James Hansen, “Letter to PM Kevin Rudd by Dr James Hansen”, 2008: http://www.aussmc.org.au/documents/Hansen2008LetterToKevinRudd_000.pdf ) and currently adds a further 64 Gt CO2-e annually (see Robert Goodland and Jeff Anfang, “Livestock and climate change. What if the key actors in climate change are … cows, pigs and chickens?”, World Watch, November/December 2009: http://www.worldwatch.org/files/pdf/Livestock%20and%20Climate%20Change.pdf ).
The World has a 1751-2006 Carbon Debt of 350 Gt C x (3.67 Gt CO2/Gt C) x $150 per tonne CO2-e = $193 trillion plus a 2007-2015 Carbon Debt of (64 Gt CO2-e /year) x ($150 /t CO2-e) x 8 years = $76.8 trillion or a total 1751-2015 Carbon Debt of $270 trillion (about 3 times the annual world GDP of $85 trillion) that is increasing by about 64 Gt CO2-e/year x ($150 /t CO2-e) = $9.6 trillion/year or about $10 trillion each year.
By way of a national example, Australia is a world-leading annual per capita GHG polluter with a 1751-2006 Carbon Debt of 5.9 Gt C x (3.67 Gt CO2-e/Gt C) x ($150 /t CO2-e) = $3.2 trillion plus a 2007-2015 Carbon Debt of 2 Gt CO2-e/year x ($150 /t CO2-e) x 8 years = $2.4 trillion i.e. a total 1751-2015 Carbon Debt of $5.6 trillion (A$7.2 trillion) that is increasing at 2 Gt CO2-e /year x ($150 /t CO2-e) = $300 billion (A$385 billion) per year. Thus Australia (population 24 million) with 0.34% of the world's population has 2.1% of the world's Carbon Debt. The Australian Carbon Debt will have to be paid by the young and future generations and for under-30 year old Australians is increasing at about $30,000 (A$38,500) per person per year, noting that the annual Australian per capita income is about $65,000 (A$83,000) (see Gideon Polya, “2015 A-to-Z alphabetical list of actions and advocacies for climate change activists”, Countercurrents, 14 January, 2015: http://www.countercurrents.org/polya140115.htm ).
In summary, 300.org urges the World to reduce atmospheric carbon dioxide concentration (CO2) to about 300 parts per million by volume (ppmv or ppm for short). In urging a target of an atmospheric CO2 concentration of 300 ppm, 300.org is informed by the advice of top world climate scientists as set out in carefully researched and documented presentations on this site (see Sitemap and the above list for numerous, carefully-researched, carefully-documented, dedicated websites relating to "300 ppm CO2 ASAP" and serious action on man-made climate change).
