The net-zero transition: What it would cost, what it could bring

View Original View Raw

Summary

In this article, McKinsey looks at the economic transformation that would occur with a transition to net-zero emissions, including changes in demand, capital spending, costs, and jobs, to 2050. The transformation would require a total of $275 trillion in spending between 2021 and 2050, and would affect all countries and sectors of the economy. To achieve net-zero emissions, the seven energy and land-use systems that account for global emissions must be transformed, and governments, businesses, and enabling institutions must work together to coordinate capital reallocation, manage demand shifts and cost increases, and establish compensating mechanisms to address socioeconomic impacts. The transition could bring growth opportunities, as well as prevent the buildup of physical climate risks, but it is also exposed to risks such as energy supply volatility.

Q&As

What are the estimated changes in demand, capital spending, costs, and jobs by 2050 for sectors that produce about 85 percent of overall emissions?
The estimated changes in demand, capital spending, costs, and jobs by 2050 for sectors that produce about 85 percent of overall emissions are an increase in spending of $9.2 trillion annually on average, a doubling of power demand, a tenfold increase in production of hydrogen and biofuels, a reallocation of labor with 200 million direct and indirect jobs gained and 185 million lost, and a shift in demand away from internal combustion engine cars and toward zero-emissions alternatives.

What are the six characteristics that define the net-zero transition?
The six characteristics that define the net-zero transition are that it would be universal and significant, require a large increase in spending, be front-loaded, have an uneven impact across countries and sectors, be exposed to risks, and be rich in opportunity.

What actions are needed to accelerate decarbonization?
Actions to accelerate decarbonization include shifting the energy mix away from fossil fuels and toward zero-emissions electricity and other low-emissions energy sources such as hydrogen; adapting industrial and agricultural processes; increasing energy efficiency and managing demand for energy; utilizing the circular economy; consuming fewer emissions-intensive goods; deploying carbon capture, utilization, and storage technology; and enhancing sinks of both long-lived and short-lived greenhouse gases.

What are the expected economic effects across countries and sectors in the net-zero transition?
The economic effects across countries and sectors in the net-zero transition would include a reallocation of labor, a shift in demand away from emissions-intensive goods, a decrease in the total cost of ownership of EVs compared to ICE cars, job gains in low-emissions forms of production, and job losses in fossil fuel-intensive or otherwise emissions-intensive sectors.

What actions are needed by governments, businesses and enabling institutions to manage the net-zero transition?
Actions needed by governments, businesses and enabling institutions to manage the net-zero transition include catalyzing effective capital reallocation, managing demand shifts and near-term unit cost increases, and establishing compensating mechanisms to address socioeconomic impacts.

AI Discussion

Me: It's about the net-zero transition and what it would cost, what it could bring. It looks at the economic transformation that a transition to net-zero emissions would entail and the changes in demand, capital spending, costs, and jobs that it would bring. It also talks about the risks and opportunities associated with the transition.

Friend: Wow, that's really interesting. It sounds like a lot of countries and sectors will have to adapt to make this transition successful.

Me: Yeah, it definitely looks like it's going to be an international effort. And it looks like the costs will be high, but it could also bring a lot of economic opportunities. It's going to be important to manage the transition carefully, and to make sure that any risks are minimized and any economic benefits are maximized.

Technical terms

Net-zero: Achieving net-zero emissions means that the amount of greenhouse gases released into the atmosphere is balanced by the amount of greenhouse gases removed from the atmosphere.
Decarbonization: The process of reducing the amount of carbon dioxide in the atmosphere.
Circular economy: A system in which resources are reused and recycled, rather than being discarded after use.
Internal combustion engine (ICE): An engine that uses a fuel-air mixture to generate power.
Battery-electric and fuel cell-electric vehicles: Electric vehicles powered by batteries or fuel cells, respectively.
Carbon capture, utilization, and storage (CCUS): A technology that captures carbon dioxide from the atmosphere and stores it in a secure location.
