As the economies and cities in developing countries grow, they will represent the total global increase in GHG emissions through the end of this century. These countries currently have the least capability to limit GHG emissions. In addition to ensuring radical GHG emission reductions in developed countries, COP26 must also now provide a range of significant assistance to developing countries to create local capabilities to reduce emissions. A broad outline is presented of what this entails.
The Intergovernmental Panel on Climate Change (IPCC) has expressed its view that “acceptable” levels of impact are compatible with a warming of only 1.5 to 2˚C; we are already 60% of the way to 1.5 ˚C temperature increase. Achieving a temperature increase of only 2˚C will be extraordinarily challenging, requiring a global drop in greenhouse gas (GHG) emissions by 50% in 2050 and to zero by 2100. There are regions of the world that have the potential and may also have the political wherewithal to limit their emissions to be compatible with a 2˚C warming. These include Western Europe, China, Japan, the “Four Tigers” of S.E. Asia, and several countries in South America. India and the United States have the potential to follow a 2˚C path but face severe political barriers (very different in each country). Together, these countries represent less than 50% of current GHG emissions.
This leaves countries representing more than half the world’s population, mostly developing countries, as major outliers. As their economies and cities grow, these countries will represent the total global increase in GHG emissions through the end of this century, as they have during the past three decades (see Figure 1). These countries have the least capability to limit GHG emissions.
It is imperative that there be developed plans and actions to enable developing countries to reduce emissions. As their cities are rapidly expanding, there is an opportunity now to create low-energy and zero-carbon infrastructure and buildings. Such plans need to include the following elements:
To carry this out, it will be necessary to:
A recent report of the Green Climate Fund (Hourcade et al., 2021, p. 12) notes the"
“misalignment [of investment] is compounded by the limited capital flows from high-savings to low-savings regions (mostly developing countries). . . .With an estimated $14 trillion of negative-yielding debt in OECD countries and $26 trillion of low carbon climate-resilient investment opportunities in developing countries by 2030. [C]apital seeking higher results should flow from developed countries to developing countries to address this gap. This is not happening. Three-quarters of global climate is deployed in the country in which it is sourced, revealing a strong preference for home-country investments where risks are well understood. This explains why sub-Saharan Africa accounts for only 5% of climate-related financial flows in non-OECD countries.”
The redirection of investment flows and associated soft investments are urgently needed. It would be desirable for the leadership of the next (planning) step to be shared by the United States and China, working collaboratively. (China and the U.S. together account for a large portion of global emissions; they worked very effectively together to enable the agreement at the Paris meeting in 2015.) This call to action is both essential and long overdue. Addressing the issues of developing countries needs to be at the forefront of topics to be discussed in Conference of the Parties (COP) to be held starting at the end of October in Glasgow.

Collapse and Catastrophe: The Need to Protect Inhabitants
In light of the recent earthquakes in Turkey and Syria, David Oswald and Trivess Moore (RMIT University) reflect on the rights that inhabitants have for buildings to be safe, healthy, comfortable and robust. However, serial and various failings in the construction supply side and its oversight by governments mean greater accountability is needed.
Blind Spots in Energy Policy
As a policy practitioner who leads a national organisation representing households and small businesses in shaping the future of Australia’s energy system, Lynne Gallagher (Energy Consumers Australia) responds to the Buildings & Cities special issue, Energy, Emerging Technologies and Gender in Homes. Insights from lived experience reveal blind spots in the design, provision and use of smart tech that adversely affect energy outcomes.
