Why don\u2019t Estonians believe?<\/strong><\/h4>\r\n

At the start of TalTech\u2019s Green Theme Month<\/a> discussion, a painful truth emerged: climate change does not concern the average Estonian until its impact is felt directly. Vares noted that in business operations, climate change shows up in supply chains: flooded warehouses in New Zealand, factories halted by heatwaves in Southern Europe, unexpected energy costs. \u201cIf you don\u2019t feel the problems on your own skin, it\u2019s as if they don\u2019t exist,\u201d Vares remarked.<\/p>\r\n

Soomere<\/a> pointed out that in the temperate zone, many of climate change\u2019s short-term effects appear beneficial \u2013 longer growing seasons, easier access to Arctic resources, new crops. \u201cThe damage seems to be somewhere far away \u2013 the benefits are here and now,\u201d he said, describing the asymmetry that fuels skepticism. At the same time, he stressed the need for a longer perspective: \u201cWhen you look at it over the long term, mathematics, physics and economics all say in unison: climate change is harmful to us all.\u201d<\/p>\r\n

Karo<\/a> added that in everyday life we often translate global risks into our own socio-economic concerns \u2013 food prices, delivery delays, heating bills \u2013 that seem to have nothing to do with climate. In this way, the cause-and-effect relationship disappears, and the big issue becomes \u201csomeone else\u2019s\u201d problem.<\/p>\r\n\r\n

Economic growth and the mathematics of sustainability<\/strong><\/h4>\r\n

Moderator Mari \u00d6\u00f6 Sarv raised a sharp question: why are sustainable solutions so often discussed only in terms of economic feasibility? In her view, caring for the planet should not be a matter of profitability, because without a functioning environment, the economy itself cannot exist.<\/p>\r\n

The conversation quickly turned to the issue of economic growth. Karo recalled that the infinite growth model has been in doubt for more than 50 years. The divergence lies in time and risk horizons \u2013 in the short term, growth may seem inevitable, but in the long term, its sustainability becomes problematic.<\/p>\r\n

Soomere approached the question of the world and sustainability from a mathematician\u2019s perspective. He explained that the world\u2019s development can be described by linear differential equations, which have only three possible solutions: a polynomial, meaning steady (de)growth; an exponential, meaning change that starts quietly but grows or declines exponentially; and oscillation, meaning cyclical movement, as seen in economic crises. From this follows his conclusion that sustainable development actually means only two possible scenarios: either exponential decline, or regular crises that keep the system in balance. \u201cEither at some point we hit the wall, or we take regular blows to keep going,\u201d he illustrated, emphasizing that the universe offers us no other options.<\/p>\r\n

Vares added that an economy based on renewable resources can grow, but there must be a limit to the use of non-renewable resources.<\/p>\r\n

The discussion also touched on Jevons\u2019 paradox: when something can be used more efficiently and cheaply, it is often consumed more, not less. In the Estonian context, Soomere gave the example of building renovation \u2013 the greenest step possible. \u201cThe greenest energy is the one that is neither produced nor consumed,\u201d<\/em> he said. But he warned that savings must strengthen the circular economy, not trigger new consumption. This way, we have a chance to break Jevons\u2019 paradox.<\/p>\r\n\r\n

GDP does not tell the whole truth<\/h4>\r\n

The panelists were unanimously critical of GDP as a measure of social progress. They stressed that a single economic indicator cannot provide a complete picture of society\u2019s development.<\/p>\r\n

Speaking of GDP\u2019s absurdities, Soomere gave the example that the public sector\u2019s contribution to economic growth can essentially arise in only two ways \u2013 either the sector expands or wages increase. Both raise the national total, but say nothing about the sector\u2019s actual development or efficiency. \u201cIn the social sciences, including economics, it is unfortunately often the case that what is easy to measure is not the most important \u2013 and the truly important things are very hard to measure,\u201d he observed.<\/p>\r\n

According to Vares, there are indeed a number of specific indicators that help assess health, the state of nature, and much more, but these are difficult, sometimes even impossible, to tie into a single whole.<\/p>\r\n

Sarv offered a vivid metaphor: well-being does not consist in endless growth, but in the ability to say, \u201cI have enough.\u201d<\/p>\r\n\r\n

Challenges TalTech can help solve<\/h4>\r\n

Soomere emphasized that several major problems can in fact be solved with the support of TalTech\u2019s engineering science. In his view, Estonia faces three fields where science and technology can make the world tangibly and rapidly better.<\/p>\r\n

First, energy efficiency. Through large-scale building renovation, up to half of previous energy costs can be avoided. This is not just theory, but construction work in which TalTech offers strong competence \u2013 from materials science to management systems.<\/p>\r\n

Second, the electricity grid. Smarter management and modern power electronics could reduce energy losses by up to one third. TalTech\u2019s power electronics researchers<\/a> are already contributing actively in this field.<\/p>\r\n

Third, water and nutrient circulation. Everything from human life that ends up in water bodies \u2013 organic matter, nutrients, pharmaceutical residues \u2013 must, according to Soomere, be captured and returned to soil, forests and fields. \u201cThis is the next major green breakthrough \u2013 technologically fully solvable and part of our profile. We just haven\u2019t asked the chemists properly yet,\u201d he explained.<\/p>\r\n

By the end of the discussion, the question arose: who is most obliged to contribute to achieving fundamental change? Vares stressed that the primary responsibility lies with producers and companies, as they shape market conditions. At the same time, she added, on a larger scale everyday choices of individuals also matter. \u201cEvery small step counts,\u201d Vares noted, referring to the power of consumers. Karo added that change does not happen overnight but across generations \u2013 values and habits also move in waves.<\/p>\r\n\r\n
