Towards a Green Party for Ecosocialism

Introduction

Capitalist domination of the world system poses existential threats to the world’s people, including the climate crisis and the threat of thermonuclear war . In this article, I consider the ideological role that ecosocialism can play in contributing to the viability of the Green Party US and its state affiliates. The Four Pillars are interpreted as a transitional ideological bridge between capitalism and socialism. I then consider the outcome of the recent German parliamentary (Bundestag) elections and the light this might shed on current issues facing the Green Party US.

Ecosocialism and the Four Pillars

The core of Green Party US ideology may be found in its Four Pillars and its Ten Key Values (10KV). The Four Pillars emerged in the early years of the Green movement, first in Germany. The Ten Key Values were developed later within the GPUS to add additional breath to the Four Pillars. Here I will focus on the Four Pillars, though the analysis remains largely unchanged by looking at the 10KV as well.

The Four Pillars are Peace, Ecology, Social Justice, and Democracy, each briefly described. 1

Consider the implications of these pillars and their relation to capitalism. We can have peace, justice, and so on, or we can have capitalism, but we cannot have both. Although the current system may be subject to incremental reform, these changes are precarious and always subject to reversal. The Four Pillars are effectively impossible to fully implement within the existing capitalist system.

Let’s look into this in somewhat greater detail.

Peace – The history of capitalism has been a centuries long history of colonial and neocolonial expansion, inter-imperialist rivalry, and war. This has meant both imperial subjugation of oppressed nations and inter-imperialist wars for the redivision of the world.
Ecology – Capitalism requires continuous growth to avoid its inherent tendency to economic instability and crisis. Only an economy based on human needs, not private profit, can overcome this.
Social Justice – Capitalism’s exploitative system depends on the economic subordination of the working and middle classes to maximize profit flow to the ruling class.
Democracy – Under capitalism, political democracy is subordinate to the needs of economic exploitation, Economic democracy is effectively non-existent.

The Four Pillars are what we might call transitional values. They raise ideals that are both necessary for the needs of millions, but their realization within the existing order is generally impossible to attain fully. This suggests that we could benefit from the addition of a fifth pillar – Ecosocialism.

Ecosocialism – The realization of peace, ecology, social justice, and democracy will only be obtained fully when we move beyond the constraints inherent to global capitalism.

The Four Pillars and the 10KV are unobtainable under capitalism. Ecosocialism provides a path to their realization.

What can we learn from the recent German Bundestag elections?

While there are many political, social, cultural, and historical differences between Germany and the US, there are also important parallels. It may therefore be instructive to look at the results of the February 2025 parliamentary elections in Germany to consider lessons for the Green Party US.

From this perspective, consider the decline of German Green Party electoral support between 2021 and 2025. In 2021, the Greens won about 14.7% of the popular vote in the Bundestag election, about 6.8 million votes nationwide. However, in 2025, the Green Party share fell to about 11.6%, or about 5.8 million popular votes.

Going into the details of this decline would require a separate article. Here, I want to address a more restricted question: where did the German Green voters go?

According to the American German Institute 2, Die Linke (a left socialist party) garnered about 700,000 votes from the Greens, from 2021 to 2025. Die Linke also gained about 290,000 new votes from nonvoters. That is, erstwhile Green voters moved left to support a socialist party that combines electoral work with community and workplace organizing. 3

These data are consistent with the view that many Green voters in Germany and elsewhere are open to an ecosocialist perspective. It is likely most of this shift represents support for Die Linke’s domestic social policies, as the Greens formed a governing coalition with the centrist Social Democrats and the pro-capitalist Free Democrats in 2021.

The Russia-Ukraine war was unlikely to have played a major role. Die Linke opposes the Russian invasion and supports sanctions against Russia but does not support German military aide to the Zelenskyy government. 5 In addition, the Putin-friendly Bundnis Sahra Wagenknecht split from Die Linke several months before the election yet failed to win sufficient votes to cross the 5% threshold required for Bundestag representation.

It seems clear that Green voters in Germany were open to a Green socialist alternative. Many stayed within the Green voter base, but a substantial number opted for Die Linke. The German election points toward the potential for an ecosocialist political pole within the US and elsewhere.

Looking forward

For many Greens,the essentials of Green politics are captured concisely by the expression “Neither left nor right, but forward”. This formulation and its variants is often attributed without apparent direct evidence 4 to Petra Kelly (1947-1992), a leading German Green.

While this view may capture something of Green values, it does not reflect the need to realize these values through the transition from capitalism to socialism. It is only from this left strategic perspective that Green values will be realized.

There is an additional reason to self-identify as (eco)socialist. It reinforces the perception that Green politics and practice go beyond environmentalism to address the entire range of issues created under capitalism, including racism, sexism, and imperialism, among others. In this regard, ecosocialism may help us attract and retain a new layer of young Green Party activists, volunteers, and candidates.

The Climate and Capitalism website 6 succinctly and starkly poses the alternatives: “Ecosocialism or barbarism.–There is no third way.”
