                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.

                CO2 Capture and Utilisation

                Country and regional highlights
                CCUS and synthetic fuel policies are being strengthened in the United States and Europe
                CO2 emissions
                CO2 use can bring important climate benefits, but with caveats
                Activity
                CO2 use for synthetic fuels remains the leading new utilisation route
                Technology installation and infrastructure
                CCU supply chains can benefit from synergies with fossil-based synthetic fuel production and CCS

                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

                Aluminium

                Country and regional Highlights
                Technological progress is being made in a range of countries, while the expected expansion of China’s emissions trading systems will be key to reducing direct emissions
                CO2 emissions
                Further action to reduce emissions intensity will be needed to get on track with the NZE Scenario
                Energy
                While the energy efficiency of aluminium production has improved, fuel switching needs to accelerate

                Trucks and Buses

                Electrification of road transport goes beyond cars and the ambition is growing
                Globally, almost 50 000 electric buses were sold in 2023, equating to 3% of total bus sales and bringing the global stock to approximately 635 000 in total. Several European countries (such as Belgium, Norway and Switzerland) and China achieved sales shares above 50% in 2023, and more than one-fifth of bus sales were electric in Canada, Chile, Finland, the Netherlands, Poland, Portugal and Sweden.
                Sales of electric trucks increased 35% in 2023 compared to 2022, meaning that total sales of electric trucks surpassed electric buses for…

                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

                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

                Country and regional highlights
                Several major economies have announced substantial new funding to modernise and digitalise their electricity grids
                Deployment
                Clean, reliable and resilient electricity systems need smart grids more than ever
                Innovation
                Digital infrastructure in electricity grids is growing
                Investment
