Electrification
Country and regional highlights
Electrification gains momentum across countries and sectors
CO2 emissions
In the Net Zero by 2050 Scenario, from now to 2030 most electrification-related emission reductions occur in transport
Energy
The share of electricity in energy demand will need to increase by 4% per year to get on track with the Net Zero by 2050 Scenario
Technology deployment
New cars and new houses are the main areas for deployment of electrification technologies

Digitalisation
Country and regional highlights
Countries are increasingly preparing their infrastructure for digitalisation
Energy
Digital technologies can help increase energy efficiency and reduce emissions across the energy system
CO2 emissions
Digital technologies are directly responsible for around 2% of energy-related GHG emissions today
Technology deployment
Deployment of smart meters and connected devices continues to grow
Investment
Investment in digital grid technologies accelerated in 2022

Aviation
Country and regional highlights
Political agreement on net zero targets for aviation has been complemented by fiscal and regulatory policies to promote sustainable aviation fuels
CO2 emissions
CO2 emissions from aviation have reached 90% of their pre-Covid-19 peak
Energy
Improvements in energy intensity have not been sufficient to counterbalance energy demand growth in recent years
Activity
Passenger activity has nearly closed the gap with pre-Covid levels

Steel
Country and regional highlights
Near zero-emission projects advance fastest in Europe, with some progress for low-emissions facilities globally
CO2 emissions
The CO2 emission intensity of steel has been relatively stable in recent years, but needs to drop significantly to align with the NZE Scenario
Energy
A reduction in reliance on coal and an increase in electricity use are required to get on track with the NZE Scenario
Activity
Material efficiency strategies are required to balance demand growth
-
Building Envelopes
Stronger efficiency is the first and best policy to bring down energy bills
Variations in energy efficiency exist both within and among countries. For example, in some European countries with similar climates it can take twice as much energy to heat the same floor area or within one country the energy consumed between the most efficient and least efficient homes for a given size can vary by a factor of up to three.

Chemicals
Country and regional highlights
Important steps to deploy low-emissions chemicals production technologies are being taken in several regions
CO2 emissions
CO2 emissions must decouple from production by 2030 to get on track with the NZE Scenario
Energy
Energy consumption for feedstock will continue to rise with production, but process energy intensity declines rapidly in the NZE Scenario
Activity
Primary chemical production is set to keep growing in the NZE Scenario

Cement
Country and regional highlights
Major policy developments of the last year hold promise for reducing emissions from the cement sector and increasing public procurement of low-carbon concrete
CO2 emissions
Cement emissions remain stubbornly high – the development and deployment of new technologies is essential to get on track with the NZE Scenario

Space Cooling
Country and regional highlights
Updated energy efficiency standards and new policies target emissions associated with space cooling
CO2 emissions
Progress on efficiency and power decarbonisation have not been sufficient to curb emissions growth from rising space cooling demand
Energy
In 2022 energy consumption for space cooling further increased by more than 5% from 2021
Activity
More than half of floor area additions to 2030 will occur in areas of the world with a high need for space cooling
-
Lighting
Country and regional highlights
Prominent progress in increasing standards and labels for lighting
CO2 emissions
CO2 emissions by lighting increased marginally in 2022, despite increased uptake of efficient lamps
Energy
Increased energy demand for service lighting more than offset a drop in residential lighting in 2022
Activity
Increasing building space and population is driving additional demand for lighting
Technology deployment
LED is now the leading lighting technology in homes

Behavioural Changes
Country and regional highlights
Governments have supported or mandated behavioural changes in buildings and on roads
CO2 emissions
Behavioural changes can quickly reduce CO2 emissions
Activity
Growth in activity is inevitable as economies develop and populations increase, but behavioural changes can help to offset these increases
Policy
Russia’s invasion of Ukraine and the resulting energy crisis have increased the salience of behavioural changes
