Let’s make accessibility sustainable at scale

When you hear the word ‘sustainability,’ do you immediately think of the environment, green energy and windmills?

When we examine the UN sustainable development goals there are multiple interconnected goals that address global challenges relating to poverty, inequality, climate change, peace and justice as well as the one we immediately think of - environmental degradation.

Recently my colleague José Esteban Lauzan blogged about the economic concept of externalities. Here I would like to talk about the parallels between environmental sustainability and accessibility and their implications on business and society.

Ageing societies

We live in societies that are rapidly ageing: a child born in Japan in 2007 will have more than 50% chance of living to the age of 107; children born in that year in most advanced economies will have similar chances of longevity. This has profound implications for society. Most disabilities are acquired as we age, so an increasingly aged population translates into increasing numbers of people living with one or more disabilities. And as technology has the power to enable people to continue working and playing an active role in life, accessibility can deliver high levels of independence and autonomy. This is hugely important when we consider that whilst we have traditionally relied on the young to support our older generations, by 2060 older people will outnumber younger people by 2 to 1.

However, despite the huge potential of technology for inclusion (speech interfaces, augmented reality and machine learning), we frequently make hurdles that people must jump over before they can realise their potential as individuals. When we don’t design our software and services with accessibility in mind, we are effectively locking people out from participation in society and from personal fulfilment.

The economic effects of this are profound. Poor accessibility directly impacts the employment prospects of hundreds of millions of disabled people worldwide. Even in societies where there is significant provision, the disability employment gap is around 31%, which rises to nearly 90% in less developed economies. Such underemployment is unnecessarily burdensome on the individual, the societies and the economies that they live in. The International Labour Organisation estimates that addressing disability exclusion could boost OECD countries’ GDP by 7%. Furthermore, accessibility efforts do not benefit disabled people exclusively: products and services designed with accessibility in mind often deliver a better user experience for non-disabled people and, consequently, gain a competitive edge.

Accessibility and sustainability

How does accessibility relate to environmental sustainability? Firstly, poorly written code is wasteful; poorly written code requires more processing time or power and therefore consumes more energy. Good code is more energy efficient so it follows that adhering to accessibility standards not only requires good efficient code but other requirements that help improve accessibility such as not setting videos to auto-play have a direct impact on energy consumption.

Disability inclusion is explicitly mentioned in 11 of the UN sustainable development goals. Businesses already report on environmental aspects of sustainability and the major indices are starting to include metrics on disability.

Societies need to be economically sustainable; inaccessibility can result in excluding 15 to 20% of the working age population from the opportunity to participate in economic life, such an outcome is hardly sustainable.
