To be able to achieve net-zero emissions, no doubt we need more feasible actions to be carried out. One of them, as Gates is saying, is that we need buildings that could “be heated and cooled without releasing greenhouse gases” – i.e. the eco-friendly constructions.
Eco-friendly construction is building a structure that is beneficial or non-harmful to the environment, and resource-efficient. This type of construction is efficient in its use of local and renewable materials, and in the energy required to build it, and the energy generated while being within it. It sounds thousands of miles afar from where we stand now base on the currently evolving technology. Yet with limited resources, we can still target the right direction: starting from the “building blocks” – sustainable material.
