Germany's national climate targets
Germany aims to become greenhouse gas neutral by 2045. It has set the interim targets of cutting emissions by at least 65 percent by 2030 compared to 1990 levels, and 88 percent by 2040.
The country's first national climate law, passed in 2019 and amended in 2021, states annual reduction targets for individual sectors such as industry and transport until the year 2030. These are set in line with the European greenhouse gas emission reduction plans.
In case a target is missed or overshot, the law states that the difference will be spread out evenly over the remaining annual emissions budgets of the sector until 2030 and beyond, with further targets set for 2040 and 2045. The ambition of Germany's national climate targets can be raised but not lowered.
Germany's climate law also states that new emission budgets for the years after 2030 will be set in 2024, and that these must be in line with the goals of the law and the requirements of the European Union – climate neutrality by 2050.
Germany is one of a handful of countries globally to have enshrined the goal of climate neutrality by or before 2050 in its national law. The European Union decided to put the 2050 target in its 2021 climate law, and about 40 other nations worldwide have committed to achieving net-zero emissions by at least 2050 through legislation or in policy documents.
Some of these expressed their target in terms of carbon dioxide (CO₂) emissions only, while the EU and Germany refer to all greenhouse gases – an important difference. In Germany's national climate law, 'net greenhouse gas neutrality' is defined as the "balance between anthropogenic emissions of greenhouse gases from sources and the removal of such gases by sinks".
The 2050 net-zero target derives from the Intergovernmental Panel on Climate Change's (IPCC) message in 2018: In order to keep global warming to 1.5°C, global net human-caused emissions of CO₂ should be brought to 'net zero' within three decades.
Interlinked with Europe's goals
Germany’s climate targets derive from the European Union's greenhouse gas emission reduction plans. The EU is currently negotiating a major overhaul of its climate and energy legislation after deciding to raise its 2030 target (to -55%) and aiming for climate neutrality by 2050. The reforms at EU level – expected to be largely decided by the end of 2022 or in 2023 – will again influence German policy and raise targets. Until then, the situation is as follows:
The EU ETS covers emissions from power generation, energy-intensive industries and civil aviation through a "cap-and-trade" approach. The EU sets a cap on how much greenhouse gas pollution can be emitted each year, and companies must hold emission allowances for every tonne of CO2 they emit. They receive or buy these permits – and they can trade them. If they emit more CO2 than they have covered by emission allowances, they face a fine of 100 euros per excess tonne.
Almost 60 percent of total domestic EU emissions are limited by an EU-wide target under the Effort Sharing Regulation. This covers emissions from transport, buildings, waste, some smaller industries and agriculture (but not LULUCF), which are not covered by the union's Emissions Trading System (ETS).
Under the regulation, member states together are to achieve an overall emissions reduction of 10 percent by 2020 and 30 percent by 2030, compared to 2005 levels. Countries are, however, required to contribute more or less depending on their relative wealth. This means that Germany has a much higher responsibility than for example Poland.
Germany's allocated emission reduction target is set at minus 14 percent by 2020 and minus 38 percent by 2030. The Effort Sharing Regulation also defines annual emission budgets (AEAs) for the years 2021-2030, following a linear reduction trajectory. Germany's climate targets and sectoral emission budgets are based on this trajectory.
If a member state fails to comply with its annual emission reduction targets, it must come up with a “corrective action plan”. Failing to comply with its reduction targets could thus mean Germany having to buy emission allocations from other member states at a high cost.
Greenhouse gas emissions – status
Germany’s greenhouse gas emissions decreased slightly (2%) in 2022 compared to the previous year. Preliminary data showed that more coal use during the energy crisis fuelled by Russia’s war against Ukraine led to rising emissions in the energy sector, while high prices pushed down emissions in industry. The country's Federal Environment Agency (UBA) warned that the reduction was not enough to put the country on track to reaching its 2030 climate target. Compared to 1990, emissions in Germany have fallen by 40.4 percent.
Germany's greenhouse gas emissions by sector
Between 1990 and 2022, all sectors achieved emission reductions, but in widely differing volumes. Each sector has been attributed an annual emissions budget in Germany's climate action law.
Germany's energy industries are responsible for the largest share (34% in 2022) of the country's greenhouse gas emissions. Here, emissions had fallen the third-most by 2022 – about 46 percent compared to 1990 levels. This decrease was to a large extent caused by the decommissioning of emission-intensive, lignite-fired power plants in the 1990s which were substituted by more efficient power plants. In recent years until the energy crisis 2022, coal-fired power generation was increasingly substituted by renewable energies and natural gas. Coal use increased in 2022, pushing up emissions.
With 22 percent, industry is responsible for the second-largest share of Germany's emissions. Here, emissions have fallen by 41 percent since 1990. Raising production processes' efficiency has reduced the bulk of emissions. The rising price on carbon allowances since 2019 also helped increase energy efficiency efforts and bring down CO2 output. For the last decade, emissions have, however, largely stagnated and while many energy-intensive companies already have detailed plans for drastic emission cuts, they lack viable business models to implement them. The energy crisis pushed down emissions as prices rose and some production was cut.
The buildings sector has achieved Germany's second-largest emission reduction since 1990 (47%). It was responsible for 15 percent of total emissions in 2022. Building emissions have, however, largely stagnated since 2011 and Germany is a long way from reaching its target of a 'nearly' climate-neutral building stock by mid-century.
Although transport was responsible for 20 percent of total emissions in 2022, the sector has struggled to reduce emissions, with nearly unchanged emissions from 1990 until the pandemic hit in 2020. Despite vehicles being less emission-intensive today, there has been an increase in road traffic with ever larger and heavier vehicles. Together with buildings, transport is an area where Germany must significantly speed up measures in order to reach its overall goal of greenhouse gas neutrality by 2045.
Agriculture emissions (excluding LULUCF) have fallen by around 26 percent since 1990, while they made up about eight percent of total emissions in 2022. A large part of this decrease took place in the years after German reunification when livestock numbers were reduced.
The sector waste and other is responsible for less than one percent of total emissions, but these have fallen by 91 percent since 1990. The sector has succeeded in avoiding harmful emissions through reorganisation and by sorting waste.
Energy transition targets
The most important tools for Germany to reach its targets on emission reduction are the roll-out of renewable energies, bringing down energy consumption, and ending the use of fossil fuels in all sectors of the economy. In order to do this, the country has also set a range of energy transition targets which primarily relate to the expansion of renewable energies and reducing energy demand.
The latest Energiewende progress report from March 2021 illustrates the structure of the country’s targets in a chart:
The energy transition is subject to an annual monitoring process led by the economy ministry, while an independent commission of energy experts provides comments. However, the pandemic and the energy crisis have disturbed the monitoring schedule and the most recent report is from 2021. The next report is expected in summer 2023 in a “modernised and adapted format”, and a shorter commentary already by January.
In March 2021, the commission said Germany must rapidly step up its national climate and energy targets to bring efforts in line with new EU-wide goals. The experts gave mixed marks on the status of the Energiewende.
Germany has made significant progress on the expansion of renewable energies. Since the launch of support payments in the country’s Renewable Energy Act (EEG) in 2000, renewables have risen from a niche technology to become the dominant player in the power mix. Almost 47 percent of the country's power consumption was covered by renewables in 2022.
However, renewables development has not been ambitious enough to reach climate targets. The government coalition in 2022 decided to rapidly speed up renewables expansion, which had lagged behind in previous years.
The country now aims to bring the renewables share in power consumption to 80 percent by 2030. Plans to enshrine a target to have an almost entirely greenhouse gas-free power supply by 2035 into the EEG were scrapped. Instead, the law now states: “After the completion of the coal phase-out, the aim is to achieve greenhouse gas neutrality in the electricity supply in Germany.” The government said it wants to “ideally” pull forward the coal exit from 2038 to 2030.
That means a massive expansion of wind and solar power. Germany aims to roughly double its onshore wind capacity to 115 gigawatts (GW) by 2030 (160 GW 2040). Offshore wind power capacity is increased to reach a minimum of 30 GW by 2030, 40 GW by 2035 and 70 GW by 2045 (up from almost 8 GW in 2022), and the country wants to achieve a total solar power capacity of 215 GW by 2030 (400 GW 2040), up from about 60 GW in 2021.
Renewables’ share in the country's gross final energy consumption was 20.3 percent in 2022 – (2020 target: 18%). This puts Germany ahead of many other industrialised nations (note that the share of hydropower in the German energy mix is comparatively low, with most renewable power coming from wind, solar and biomass).
Energy efficiency targets
Germany has made notably less progress on its targets to reduce energy demand than on its renewables targets. Increasing energy efficiency is generally seen as a main pillar of the Energiewende and essential to reaching climate neutrality by 2045. But saving energy on a large scale – by insulating buildings, changing behaviour and introducing many new and often expensive technologies in different sectors – requires everyone’s participation, and has proven a hard sell so far.
The government coalition in 2023 aims to adopt an energy efficiency law. Energy efficiency targets would be set for 2030, 2040 and 2045 for primary and final energy, which would also correspond with the requirements of the amendment of the EU Energy Efficiency Directive. The government’s target is to reduce final energy consumption by 26.5 percent by 2030 (to 1,867 terawatt hours (TWh)), compared to 2008.
According to earlier targets, Germany aimed to reduce primary energy consumption by 20 percent by 2020 compared to 2008 levels. However, even with the slump caused by the coronavirus pandemic, consumption was only reduced by 17.3 percent (-17.7 by 2022).
Emissions in a historical context
A look back on Germany’s historical emissions track record since 1850 reveals that the country’s greenhouse gas emissions have been very much dependent on economic fluctuations and alternations between war and peace.
World War One, followed by the economic and political crises of the 1920s and early 1930s, had a very visible influence on emissions, as did the build-up to, and aftermath of, World War Two. Apart from these anomalous periods, Germany's greenhouse gas emissions were on a constant climb until they peaked in 1979 at 1,390 million tonnes CO2 equivalents.
Emissions have been gradually declining since then – also since the international reference year of 1990. Germany was given a head start in 1990 when, following the fall of the Berlin Wall and reunification, the decline of the East German industrial and power sectors meant automatic CO2 reductions (so-called “wall fall profits”). In 2009, emissions dropped by 6.9 percent compared to the previous year due to the economic crisis, which saw many companies scale down production. However, in the years that followed, the hope that this trend would continue remained unfulfilled. Impacts of the COVID-19 pandemic could lead to a similar scenario in 2020 and the years that follow, first emission estimates show.
A comparison between Germany's emissions in the past and its current emissions targets sheds light on the annual amount of emissions the country still needs to cut.
- By 2020, Germany would have to reach the emission levels last seen in 1953 or 1941
- By 2030, the country must reduce its emissions to levels similar to those in 1948 or 1907
Although Germany has largely managed to decouple economic growth (measured in GDP) from a rise in greenhouse gas emissions, the record of the past three decades shows that the country will need to implement significant changes if it wants to reduce emissions to meet its targets.
The year 1855 falls within the beginning of the industrial revolution in Germany. For the first time, Germany's fragmented states formed a customs union, which also included parts of today's Poland and the Czech Republic (the data set used for this article generally reflects the emissions from a country’s territory within the boundaries of the time).
The customs union covered an area with a total population of around 32 million, not even half of Germany's current population of around 82 million. Coal mining regions, such as the Rhine-Ruhr area and Saxony, became the first industrial hubs, and the population was growing because of new achievements in medical services and hygiene.
A large share of emissions (21.6%) still came from the agricultural sector. 62.5 percent came from energy use and just 1.4 percent from industrial processes. Despite a boom in rail travel (in the 19th century 50,000 kilometres of rail tracks were built in the German territory) the most common form of freight transport for short distances was horse-drawn carts while people generally used carriages or simply walked.
