- Researchers made 'Average Wellbeing Index' model data of govt, climate, etc
- The model showed different policies that impacted climate change and world
- The model estimated pathway leading to stabalising global temperatures
London: Tackling inequality is key to securing the public support needed to overhaul the global economy and reverse climate change, an update to the landmark 50-year-old computer simulation of environmental stress has found. Based on modelling by MIT scientists of a world destabilised by growing consumption, the 1972 “Limits To Growth” simulation has been attacked as flawed by some but applauded by others as prescient of accelerating planetary stress.
Building off its predecessor, the Earth4All model developed by a cross-discipline team of researchers sought to explore what it would take to increase the wellbeing of humanity during the rest of this century using data from the 1980-2020 period.
Its central conclusion was that, if left unchecked, rising inequality in the next 50 years would leave people less trusting of governments and other institutions, making co-operation to deal with climate change and other threats more difficult. Study co-author Per Espen Stoknes said,
When social trust goes down, this limits the speed of public policy action. This translates into how much regulation and subsidies you can do in terms of greening the economy and energy system.
To track wellbeing, the researchers created an ‘Average Wellbeing Index’ using data including disposable income, income inequality, government services, the climate crisis, perceived progress, and their relationship to measures of social trust.
Using two scenarios – labelled ‘Too Little Too Late’, with no change to human behaviour, and ‘The Giant Leap’, where the world’s economic and social systems are transformed – the model seeks to show how differing policies would impact the world.
Under the business as usual scenario, the wellbeing of the average worker – taken to mean those who spend most of what they earn in a year – peaks around the year 2000, before declining out to 2050 and then levelling to 2100, despite continued growth in the global economy over the same period.
By making changes such as phasing out fossil fuel use, putting adequate pensions in place, taxing the richest 10% more and cancelling the debt of low-income countries, the Giant Leap pathway allowed wellbeing to continue to rise.
The model estimated the pathway leading to a stabilisation of global temperatures below 2°C above the industrial era and eradicating to poverty by 2050 would cost 2-4% of global output, or between $2 trillion-4 trillion annually.
By comparison, the International Monetary Fund estimated that governments together put in $9 trillion of fiscal support for their economies in the first five months of the coronavirus pandemic alone.
“We absolutely need to place a value on social and environmental and economic indicators at the same level,” said co-author Sandrine Dixson-Decleve, co-president of the Club of Rome think tank which originally published the “Limits To Growth” report.
Inequality and poverty play a huge role in enabling us to move forward, she added. Net-zero poverty has to be as much of a goal as net-zero emissions
A book outlining the results of the model, “Earth for All: A Survival Guide for Humanity” will be published in German on Tuesday, with versions in English and other languages following.
Doug Heske, chief executive of U.S.-based Newday Impact Investing, signalled its value for ESG investors.
Earth for All provides a powerful new framework for how responsibly-minded investors can thoughtfully allocate capital in ways that will have the greatest impact, he said.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – the LGBTQ population, indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the current COVID-19 pandemic, the need for WASH (Water, Sanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fight malnutrition, mental wellbeing, self care, science and health, adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues like air pollution, waste management, plastic ban, manual scavenging and sanitation workers and menstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
