The world population is expected to grow from the 7.5 billion currently (5 billion in 1987) to 10 billion by 2050.
This increase is driven by a combination of enhanced life expectancy and high birth rates. While the former has been a global phenomenon, the latter is restricted to the Asian and African continents. Projections beyond 2050 are more varied. Some projections see declining, while others seeing increasing world population. Regardless of the longer-term picture, the anticipated near-term growth in population will put considerable stress on the planet in the coming three decades.
THE CHALLENGE TO THE PLANET
There is widespread consensus in the scientific community that increased human emissions of greenhouse gases (GHG – carbon dioxide, methane, and nitrous acid) has caused global warming and climate change. The average temperature has increased 1.3 degrees centigrade between 1910 and 2015. GHG emissions were 60 percent higher in 2014 compared to 1990, showing an accelerating trend compared to the slower increase since the industrial revolution.[i]
Accounting for a quarter, fossil fuel consumption is the single largest source of GHG emissions.[ii] Hence, the push for energy conservation and the move to alternative sources of energy, especially renewable energy.
Agriculture, forestry, and other land uses account for 24% of GHG emissions. Rising population and increasing standards of living are expected to raise substantially the demand for food. For example, one expert argued that the planet must produce more food in the next four decades than all farmers have harvested over the past 8000 years.[iii] To avoid hunger and starvation, it is imperative to increase yields, reduce wastage, while conserving consumption of water and energy as well as minimizing the use of chemicals and antibiotics.
Increasing population combined with urbanization will put great pressure on cities. The United Nations report on urbanization envisages an increase of 2.5 billion in the world’s urban population by 2050. Given that the overall global population is also expected to grow by 2.5 billion, the deleterious effects of the increased population will be concentrated in the urban areas. Since 90% of this urban growth will be in Africa and Asia, they will see enormous demand for urban infrastructure, particularly, affordable housing, large public transportation networks, and health care access.
On 25th September 2015, recognizing the challenges above, the United Nations adopted 17 goals related to people and planet.[iv] Associated with these goals, 169 specific targets were set as part of the “2030 Agenda for Sustainable Development” to end all forms of poverty, fight inequalities, and tackle climate change.[v] While not legally binding, all global leaders committed to progress in meeting these goals (see Appendix 1).
HOW SHOULD BUSINESS ENGAGE WITH SUSTAINABILITY?
Most business firms, especially small and medium enterprises, probably see doing nothing as the smart strategy. They view their mandate as serving customers and generating returns for the shareholders. Managing the impact on society is out of the scope of their activity and thought better left to the government and/or NGOs. In any case, the problems of sustainability seem too large and expensive for any individual firm to tackle, or even make a difference.
More astute business leaders, especially of large organizations, recognize that demands from important stakeholders require sustainability to be incorporated within their corporate agenda. In one Accenture survey, 97% of industry CEOs said that sustainability is critical for the future success of their business.[vi] On further reflection, business leaders realize the pursuit of sustainability can have some of the following benefits for their firms:
Goal 1 End poverty in all its forms everywhere
Goal 2 End hunger, achieve food security and improved nutrition and promote sustainable agriculture
Goal 3 Ensure healthy lives and promote well-being for all at all ages
Goal 4 Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all
Goal 5 Achieve gender equality and empower all women and girls
Goal 6 Ensure availability and sustainable management of water and sanitation for all
Goal 7 Ensure access to affordable, reliable, sustainable and modern energy for all
Goal 8 Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all
Goal 9 Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation
Goal 10 Reduce inequality within and among countries
Goal 11 Make cities and human settlements inclusive, safe, resilient and sustainable
Goal 12 Ensure sustainable consumption and production patterns
Goal 13 Take urgent action to combat climate change and its impacts
Goal 14 Conserve and sustainably use the oceans, seas and marine resources for sustainable development
Goal 15 Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss
Goal 16 Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels
Goal 17 Strengthen the means of implementation and revitalize the global partnership for sustainable development
