 Our Common Future was published on October 1987 by the United Nations. The report is also known as the Brundtland Report, referring to former Norwegian prime minister Gro Harlem Brundtland. Brundtland was the chair of the World Commission on Environment and Development (WCED). “Our Common Future placed environmental issues firmly on the political agenda; it aimed to discuss the environment and development as one single issue [(Brundtland1987)].” The report famously defined sustainable development as “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs [(ALBERTA2018)].” Our Common Future was published on October 1987 by the United Nations.

-Sustainability is more than just environmentalism; “In addition to natural resources, we also need social and economic resources. Embedded in most definitions of sustainability we also find concerns for social equity and economic development [(ALBERTA2018)].” The concept of sustainability is a holistic approach that covers three pillars; the economic, environmental and social. This approach is shown in Figure {{ref>flabel15}}. The three pillars, sometimes better known as people, planet and people, will each be addressed in this chapter. We don’t want sustainability do be yet another part of the job, it should be a guiding influence for the whole project. +Sustainability is more than just environmentalism; “In addition to natural resources, we also need social and economic resources.

 The lifting mechanisms incorporated in the desk have undergone rigorous testing by the respective manufacturers to verify their load-carrying capacity. Furthermore, an additional test was conducted specifically on the table top to ascertain its ability to withstand the pressure exerted by a user sitting and standng on it. For this test, the desk wheight with the installed components plus a single person was set at 300 kilograms, and a safety factor of 2 was applied. Consequently, a load of 600 kilograms (approximately 6000N) was exerted on the desk.By employing this safety factor, it can be assured that the desk is capable of withstanding the specified load, even when the user is standing on it or other heavy things will be placed on it. The load was applied at the center of the table, which is considered the most susceptible area. The experimental setup for simulating the lifting mechanism and the boxes underneath is depicted in Figure {{ref>flabel39}}, respectively. To prevent movement, both sides were constrained in the x-, y-, and z-directions. The lifting mechanisms incorporated in the desk have undergone rigorous testing by the respective manufacturers to verify their load-carrying capacity.
