The unsustainable use of online video
28 July 2019
The report published July 2019 “Climate crisis: The unsustainable use of online video – A practical case study for digital sobriety” was led by Maxime Efoui-Hess, an engineer specialized in climate and computer modeling, who graduated from ISAE-SUPAÉRO, Université Paul Sabatier and the French Meteorology University.
The environmental impact of digital technology is now recognized as unsustainable, but continues to grow. The energy consumption of digital technologies is increasing by 9% a year, and already represents 4% of global greenhouse gas emissions. The use of digital technology accounts for 55% of its energy consumption, compared to 45% for the production of equipment. This was demonstrated by our report “Lean ICT – Towards digital sobriety” published in 2018.
Getting this impact under control implies requires a transition from digital intemperance to digital sobriety. This means prioritizing the allocation of resources as a function of uses, in order to conform to the planet’s physical boundaries, while preservingthe most valuable societal contributions of digital technologies.
4 main types of contents generate 60% of global data trafic.
We live in a world where only one form of digital use, online video, generates 60% of of world data flows and thus over 300 million tons of CO2 per year. This use is far from being “dematerialized”. On the contrary, it represents 20% of the greenhouse gas emissions of all digital devices (use and production included), and 1% of global emissions, i.e. as much as Spain. The rest of the uses of digital technologies comprise 20% of other types of video, and 20% of non-video uses – the latter covering all the non-video possibilities opened by digital technologies.
Online video, which is the subject of this report, is therefore a particularly significant practical case for the implementation of digital sobriety. In this 60% of global data flows generated by online video, there are 4 main types of content, none of which is negligible.

CEI conference in Istanbul
30 June 2019
Over 180 delegates from 14 countries meet in Istanbul at the annual CEI conference entitled: Sustainable Living in a Big City. They will present their projects by 6 July, take part in debates and workshops related to environmental issues in the big city.
COP 24 Katowice, Poland
18 December 2018
Through December 2 to 14, 2018, the COP 24 was held at the International Conference Center in Katowice. Over 20,000 delegates from 196 countries took part in it.Negotiators in Poland have finally secured agreement on a range of measures that will make the Paris climate pact operational in 2020.Last-minute rows over carbon markets threatened to derail the two-week summit - and delayed it by a day.Delegates believe the new rules will ensure that countries keep their promises to cut carbon. Delegates to the UN climate conference in Katowice, Poland have reached agreement on how to implement the 2015 Paris Climate Accord, which comes into force in 2020. Acceptance of the so-called Katowice rulebook means that we have the first international agreement that obliges all parties to perform specific actions. The document counts several hundred pages and there is no doubt that it is historical. Turkey and Brazil did not want to agree to sign it for the longest time. Brazil had been pushing for a weaker set of rules on carbon markets, despite strong opposition from many other countries. Developing countries believed that countries that have already developed should pay for transforming economies. India at the last plenary session said they did not agree to all the records but did not want to block the deal. In the end, a common position was worked out.The Katowice agreement aims to deliver the Paris goals of limiting global temperature rises to well below 2C.

GEEP Call to Action
19 October 2018
The Global Environmental Education Partnership has created a pledge for reinvigorating Environmental Education world-wide in light of urgent sustainability challenges. In the pledge the global environmental education community is asked to work toward three visionary goals. Hundreds of educators around the world have vetted these actions and helped outline key areas of focus for the field.Details here.
Rise for Climate

World Scientists’ Warning to Humanity: A Second Notice
26 February 2018
Twenty-five years ago, the Union of Concerned Scientists and more than 1700 independent scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 “World Scientists’ Warning to Humanity” (see supplemental file S1). These concerned professionals called on humankind to curtail environmen-tal destruction and cautioned that “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.” In their manifesto, they showed that humans were on a collision course with the natural world. They expressed concern about current, impending, or potential damage on planet Earth involving ozone depletion, freshwa-ter availability, marine life depletion, ocean dead zones, forest loss, biodiver-sity destruction, climate change, and continued human population growth. They proclaimed that fundamental changes were urgently needed to avoid the consequences our present course would bring. The full text of the article by William Ripple and others.
Call for action
19 January 2018
The organization Global Environmental Education Partnership focuses on using the potential of environmental education in solving pressing global problems, both environmental and social.One of GEEP's scientific advisers, Professor Arjen Wals from Wageningen University in the Netherlands, publishes a questionnaire on his blog, which is to be used to determine the direction of GEEP's strategic activities for the next 10 years. In this research should not lack the opinions of environmental educators and not only. We encourage you to participate in shaping the global GEEP action plan for environmental education by filling out the questionnaire available here.

Teachers Training Course
15 September 2017
CEI Poland is organizing Teachers Training Course for teachers from Poland and abroad, from 6th to 10th of November this year. This is one of the tasks under the ERASMUS+ project „EduCO2cean - STS Education models to transmit to society the challenge of global change in the ocean”, coordinated by the ASPEA (CEI Portugal), in collaboration with the University of Vigo Spain, Ciencia Viva Portugal, Marine Alliance for Science and Technology for Scotland, CEI Poland and schools in Portugal, Spain and Poland. The aim of the five-day course is to present methods for creating student activity and promoting good practices in environmental education. Classes will be conducted in English and Polish language, 8 hours a day, by academic staff of the University of Silesia. The partner is the Scientific Information Center and the Academic Library in Katowice, and the event is covered by the Honorary Patronage of the President of the City of Katowice and the Dean of the Faculty of Biology and Environmental Protection, University of Silesia. This demonstrates the great importance of ecological education for local authority. But environmental education is also very important in the world, for international organizations and universities. Very inspiring and compelling to think in this regard are words from interview with Arjen Wals* Transgressive learning in times of global systemic dysfunction, quoted below:Well we need nothing less than a radical re-orientation of education. The one single species that has been able to alter the Earth’s ecosystems, climates, ocean levels, biodiversity in detrimental ways, must now find a way to do better. Indeed positivistic, reductionist, empirical analytical science and a neo-liberal economic system that demands continuous growth and innovation has broad us loads of possibilities and has made live for many very comfortable – although certainly not for all, but we now are beginning to understand that the ‘side-effects’ of this way of thinking are accelerating and limiting the futures for humanity and the other species we are dragging into our mess.
Note: for people from abroad, interested in participation, there are still several places for free. Accommodation in Katowice on your own cost. Info by contact box. Detailed program of TTC.
