Ten zazrak roku 2014 a 2015 je obavam sa tvojou domnienkou, pretoze taketo zavery mozu vychadzat iba pri pouziti vedeckych metod, a to co si tu napisal ma od toho daleko. V praxi sa medzi ekonomickymi a fyzikalnymi ukazovatelmi prejavuju rozne opozdenia a podobne.

Co sa tyka decouplingu, roky to bola velka tema ekonomov, ale novsie studie ktore som si na tuto temu cital typicky tvrdia, ze sa to nestalo. Skratka tieto dve veci idu ruka v ruke.

Ked budem mat cas, mozem skusit popisat preco si myslim ze to tak je.

IMF, 2018:

We have proposed a simple but comprehensive framework—the trend/cycle decomposition that is widely used in many other fields in economics—to investigate the decoupling of emissions and growth. For the twenty largest emitters, the average trend elasticity, viz. the response of trend emissions to a 1 percent change in trend GDP, is 0.4. For the advanced economies within this group, the elasticity averages zero; some countries have negative elasticities, suggesting that they had made progress in decoupling their trend emissions from trend GDP. Taking account of consumption-based emissions weakens the case for progress but does not overturn it. Encouragingly, we find suggestive evidence that trend elasticities can be lowered through policy efforts on the part of countries. Moreover, our investigation of the historical relationships between emissions and GDP shows that elasticities in recent decades are considerably lower than in previous decades.

EC, 2019
To solve such research gap, this paper assesses the decoupling in the EU focusing on potential environmental impacts, complementing a production-based approach with two options for accounting for the impacts of consumption. The aim of this paper is to evaluate the decoupling of the economic growth (in terms of Gross Domestic Product) from the environmental impacts due to EU-28 consumption, assessed by means of life cycle assessment (LCA). The decoupling is then assessed in impact terms rather than limited to pressures by using the Environmental Footprint (EF2017) indicators, which allows assessing 16 different impacts. The Consumption Footprint indicator quantified the environmental impacts of EU apparent consumption, including the territorial impacts (Domestic Footprint) and the embodied impacts in both imports and exports (Trade Footprint). The inventory of pressures for the trade component is compiled either with a bottom-up approach (process-based LCA of representative traded goods) or a top-down approach (input-output-based LCA). Methodological aspects influencing the decoupling assessment and the resulting outputs are presented and discussed. According to the results, the environmental impacts of EU-28 consumption showed decoupling during the last decades (2005–2014), between relative to absolute decoupling depending on the inventory modeling approach taken. Some countries showed higher decoupling levels than others displaying a heterogeneous map of EU-28 decoupling, which was led by acidification, particulate matter, land use and eutrophication impacts. Notwithstanding current limitations, the assessment of decoupling using consumption-based environmental indicators is very promising for supporting policy-making towards addressing the actual impacts driven by the EU production and consumption system

hehe no nemam teraz cas si to vsetko studovat, ale je to s tou statistikou tazke, ja som si pred casom cital studie s presne opacnym vysledkom, tj. ze decoupling nefunguje.
Kazdopadne faktom zostava, ze emisie nadalej rastu, a jediny krat v ostatnych rokoch padli prave pocas ekonomickej krizy.

Ja som tie štúdie hladal, nebolo to tak že by som niečo vypichoval, takže si naopak veľmi rád prečítam že decoupling nefunguje. Nehovoriac o tom že rec nebola o tom či nefunguje, ale či principiálne nemôže fungovať.
