Climate Change, Sustainable Development and the Green Economy

What is Climate Change? 

The Earth is getting hotter and the  climate is changing primarily due to human activities – such as burning of fossil fuels, deforestation, changing the natural use of land, industrial processes and unsustainable agriculture - that emit planet-warming gasses, referred to as greenhouse gases. . The heating effect of the planet is referred to as global warming, which in turn causes climate change.

Watch this 80 second video from the Australian NGO the Climate Council for a brief explanation on how Greenhouse Gases change the climate and heat the planet.

PLEASE NOTE: A “doona” is an Australian term for blanket.

 The Climate Council is an Australian non-profit that drives climate change      awareness, go to there website to find out more www.climatecouncil.org.au

The Impacts of Climate Change

People around the world are already feeling the numerous social, economic and environmental impacts of climate change.

In the Western Cape, the projected direct impacts of climate change include:

  • ·Higher average annual temperatures
  • ·Higher maximum temperatures
  • ·More hot days and more heat waves
  • ·Higher minimum temperatures
  • ·Fewer cold days and frost days
  • ·Reduced average rainfall
  • ·Rising sea levels
  • ·Increased fire risks
  • ·Increase in the frequency and intensity of extreme weather events, including floods, droughts, and storm surges.

While the above are projected, many of these changes are already being realized.

The direct impacts mentioned above create a variety of indirect impacts, such as the impact of increased drought or extreme weather on businesses, employment and food production, the impact of high temperatures and increased heat waves on human health, and the impact that fewer frost days has on the deciduous fruit industry.  If businesses and society continue to operate as they currently do, climate change will be devastating to economic and social progress, threatening health, safety and livelihoods.  

As an example, the drought that was experienced in Cape Town and the Western Cape from 2015 to 2018 was record-breaking, with the lowest rainfall since record keeping began. The impacts on businesses and their employees were profound, with the provinces’ tourism, hospitality and agricultural industries hit hardest. Although Cape Town has experienced several significant droughts in its history, modelling by University of Cape Town (UCT) researchers  found that the risk of drought has increased substantially because of global warming (read more on UCT’s website here).

Many scientists across various fields of research, research and civil society organisations and anticipate climate change and its indirect impacts to be the worst crisis of our time. The World Economic Forums annual Global Risks Report series has many times highlighted climate change and climate change related risks in the top 5 global risks both in terms of likelihoods and impact since at least 2013. The Global Risks reports share the results of the Global Risks Perception Survey (GRPS), completed by over 650 members of the World Economic Forum’s leadership communities and overseen by the Global Risks Advisory Board. The 2021 Global Risks Report has climate change related risks occupying 4 of the top 5 risks in terms of likelihood and 3 of the top 5 risks in terms of impact. The diagram below depicts the global risks as they have changed over the years from 2012 to 2021.

We can, however slow climate change and prevent its worst impacts by reducing the emission of greenhouse gases (mitigation) and by implementing means to adapt to a changing climate.

What role does Sustainable Development have to play?

In general, while decreasing overall poverty and increasing access to food and employment, previous approaches to development have been environmentally destructive and socially dividing on a global scale, while failing to effectively address equality.

Negative impacts of previous and current approaches to development include:

  • Emissions of greenhouse gasses by human activities have increased by over 700 times in the 200 between 1819 and 2019 years [1] and the level of greenhouse gasses in the atmosphere are higher than they have been for over 800 000 years [2]. This is leading to continued heating of our planet, resulting in climate change and its various direct and indirect impacts on social, natural and economic systems.
  • 75% of the Earth’s land-based environment has been “severely altered” by human actions [3]
  • 66% of the Earth’s ocean environments have been “severely altered” by human actions [3]
  • 85% of wetlands present 300 years ago have been completely lost [3]
  • In 2015 33% of ocean fish stocks were being harvested at unsustainable levels, while 60% were being fished at their maximum sustainable levels [3]
  • 50% of coral reefs have been lost since 1870s [3]
  • 1 million plant and animal species are currently threatened with extinction, many  of which could be lost within decades [3]
  • The populations of mammals, birds, fish, amphibians and reptiles have decreased by 68% since 1970 [4]
  • Since 1990, income inequality has increased in most developed countries and in some middle-income countries where more than 71% of the world population live. [5]
  • Despite progress in some countries, income and wealth are increasingly concentrated at the top. From 1990 to 2015, the share of income going to the richest 1 per cent of the global population increased in 46 out of 57 countries. [5]
  • Progress on improving gender equality has been slow. [5]

The impacts mentioned above have been largely as a result of developmental approaches that focused mainly on economic growth and industrialisation, often at the expense of the environment, natural systems and social justice.

Sustainable development was first conceptualised in 1987 where it was defined as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. Sustainable development requires the pursuit of not only economic growth but also the building of an inclusive, sustainable and resilient future for people and nature.

The core elements of sustainable development are economic growth, social inclusion and environmental protection. These elements are interconnected, and all are crucial for the well-being of individuals and societies.

In 2015, the global community, through the United Nations, adopted and signed onto the 2030 Agenda for Sustainable Development. Described as a “plan of action for people, planet and prosperity”, it laid out 17 Sustainable Development Goals (SDGs) that the global community must pursue by 2030 to ensure that we develop our human systems in a  manner than improves equality, human prosperity and wellbeing, and maintains and restores the health of our planet’s vital natural systems on which all life on Earth and our economic systems rely.

The 17 SDGs (see below) also have 169 targets that can be monitored to gauge progress towards the achievement of the goals.

The link between climate change, sustainable development and the green economy

Climate change and many of the other environmental and social impacts of unsustainable development are largely driven by the way our economic systems function and are structured.

Effectively achieving sustainable development and fighting against and adapting to climate change and its numerous impacts requires a “greening” of the way our economic systems function. This would mean moving from our current unsustainable economic systems to a green economy.

A green economy:

  • produces as few greenhouse gas emissions as possible
  • uses resources very efficiently, minimising or even eliminating waste
  • is socially inclusive
  • fights against further climate change while adapting to the current and / or imminent effects of climate change and
  • bases economic activity on sustainable development. 

A green economy acknowledges that sustainable economic growth and development takes place through the efficient and responsible use and protection of natural ecosystems, so that they can continue providing the resources, services, environment and climate on which our well-being and economy rely.

The green economy is vital to mainstreaming sustainable development and climate change resilience into our global and local economic systems, and in so doing ensuring a prosperous future for people and planet.
