Climate Protection and Decarbonisation

According to the terms of the Paris Agreement, the signatories commit to restricting global warming to “well below 2 °C”. Moreover, efforts are to be taken to keep warming to less than 1.5 °C in order to limit the negative effects of climate change. This translates to a reduction in greenhouse gas emissions that dwarfs all initiatives thus far. In light of this, Germany aims to become climate-neutral by 2050. The EU has adopted the same target.

Limiting global warming by transforming society

The challenge of climate change

The dangerous effects of climate change have the potential to shape the worldwide community more strongly than any other influence. The so-called 1.5- or 2-degree target is an important consensus. If this limit is exceeded, the probability is considered too high that climate change will become self-reinforcing and irreversible, among other things because permafrost will thaw and the salinity of the oceans will decrease. According to the World Biodiversity Council, between 50 and 700 million people could lose the basis for their livelihoods as a result of unchecked climate change. This would cause people to be expelled or flee from their homes and trigger military conflicts. Species of all kinds of plants and animals would be threatened with extinction – even more so than is the case today.

Measures against climate change

As of June 2020, 189 of 197 signatory parties (196 nations and the EU) had ratified the Paris Agreement. On 4 November 2020, the USA – second-largest emitter of CO2 in the world after China – have officially withdrawn from the agreement. However, under the new President-elect Joe Biden, they have announced to return to the Paris Agreement.

The agreement involves each state declaring what it intends to do to protect the climate. These nationally determined contributions (NDCs) comprise a broad range of highly specific measures. Nepal, for instance, intends to fight deforestation, while Chile has pledged to expand the use of solar and wind power. Whether or not the voluntary commitment approach of the Paris Agreement will take hold and eventually prove effective remains to be seen.

Every five years, the signatories to the Paris Agreement have to submit ambitious new targets to the United Nations. This means they will have to do this for the first time by the end of 2020. It is essential that this happens because even if the NDCs are met – which is questionable – they will not achieve the two-degree target as they stand. Initial impetus has been provided with the European Green Deal. However, additional systematic changes and incentives are needed – especially in the fields of energy, mobility and buildings – to achieve the targets which have been set. In September 2020, the EU Commission proposed increasing the target for reducing greenhouse gas emissions by 2030 (emissions and reduction) from 40 percent to at least 55 percent compared to 1990 levels.

The Paris Agreement also contains a commitment to help developing countries adapt to climate change. The industrialised nations have undertaken to provide public and private funding of 100 billion US dollars for this purpose each year from 2020 onward. Moreover, the financial markets are to be overhauled to align them with the climate goals. The German government’s Sustainable Finance Committee is working on ways in which this can be done. The German Council for Sustainable Development initiated the debate between 2017 and 2019 through the Hub for Sustainable Finance.

Germany’s climate targets

To meet the climate protection targets, it is essential that the energy sector, but also agriculture, industry, transport and the buildings sector, drive down their emissions significantly. Germany set out the scale of the necessary reductions with its Climate Protection Act in December 2019. This stipulates a decrease of at least 55 per cent in CO2 emissions by 2030; the target is broken down by sector. In transport, for example, emissions are to fall from 150 to 95 million tonnes of CO2 equivalents per year. Germany intends to be climate-neutral by 2050.


The major challenges include sufficient electricity use, expanding the grid, storing power, completing the phase-out of coal, bringing about a shift in mobility and agriculture, changing industrial production and its decarbonisation, and linking the heat, mobility and power supply sectors. As part of these efforts, the German government intends to establish hydrogen as a source of energy. The German Council for Sustainable Development (RNE) is calling for this to be implemented faster, more consistently and with greater international involvement than it has been to date. For the RNE, social aspects and fairness in distribution also play an important role in the transformation. The main philosophy behind the Council’s work is to view sustainability as part of a larger context – the energy transition is one component of a more general transformation. With this in mind, the RNE has great expectations of Germany’s presidency of the Council of the EU and calls on all European Member States to align the recovery from the crisis with the core principle of sustainability.
