Emissions from the industry sector decreased by 41% between 1990s and 2021 – only slightly faster than overall emissions.22 Energy-related emissions decreased faster than process-related emissions mostly due to improving efficiency of East German industry after the reunification in the early 1990s.
Electrification combined with energy efficiency measures are the main drivers to decrease energy related emissions in the industry sector according to the 1.5°C compatible pathway. Such scenarios assume an increase in the share of energy consumed as electricity to increase from 34% in 2019 to 47% in 2030 and between 64-67% in 2050, as the sector gets electrified.
Significant reduction of process related emissions will in many cases require different technologies, e.g. application of green hydrogen for steel production. Some German companies are taking positive steps in this direction, e.g. Thyssen Krupp aims to make its steel “climate neutral” by 2045 and is deploying first pilot projects to achieve this goal.25,26 Another option is replacement of existing high carbon materials by low carbon alternatives (e.g. for cement) as well as recycling (e.g. steel scrap). Implementation of some of these measures could accelerate emissions reductions in the sector.
The main policy driver of emissions reduction in Germany is carbon pricing through the EU Emissions Trading System. To decrease the potential threat of carbon leakage, many industry sectors receive from allowances, which reduces the scheme’s effectiveness on decarbonisation. Introducing Carbon Border Adjustment Mechanism, combined with phase-out of free allowances would accelerate decarbonisation of the sector. Using such instruments as Carbon Contracts for Difference could facilitate deployment of low carbon technologies.

30 While global cost-effective pathways assessed by the IPCC Special Report 1.5°C provide useful guidance for an upper-limit of emissions trajectories for developed countries, they underestimate the feasible space for such countries to reach net zero earlier. The current generation of models tend to depend strongly on land-use sinks outside of currently developed countries and include fossil fuel use well beyond the time at which these could be phased out, compared to what is understood from bottom-up approaches. The scientific teams which provide these global pathways constantly improve the technologies represented in their models – and novel CDR technologies are now being included in new studies focused on deep mitigation scenarios meeting the Paris Agreement. A wide assessment database of these new scenarios is not yet available, thus we rely on available scenarios which focus particularly on BECCS as a net-negative emission technology. Accordingly, we do not yet consider land-sector emissions (LULUCF) and other CDR approaches which developed countries will need to implement in order to counterbalance their remaining emissions and reach net zero GHG are not considered here due to data availability.

32 Confirming previous analysis indicating that: “Germany needs to phase coal out of its electricity sector by 2030 to meet its obligations under the Paris Agreement. This is earlier than the dates discussed so far by the Coal Commission, a body established to come up with a coal exit plan by the end of 2018.”29
33 According to the Carbon Contracts for Difference, investor in low carbon technology (e.g. low carbon steel) receives subsidy that amounts to the different between the cost of producing traditional product and the low carbon alternative. This amount is reduced by what the investor would have to pay in carbon price anyway, e.g. in the framework of the EU ETS.
