Illuminem does this through three pillars. On the one hand, there are articles, newsletters and contributions from over 2,000 experts around the globe from 500 curated sources. On the other hand, there is a Sustainability Data Hub that contains information on the sustainability of thousands of companies. Most recently, Illumnem sells its own sustainability solutions.
The platform has 700,000 active users – including 7,000 executives – and 20,000 newsletter subscribers. There are a total of three newsletters, all of which are published weekly in English.

The “Trellis Briefing” is one of the largest and best greentech newsletters in the world. The company behind the newsletter is Trellis (formerly GreenBiz). As an organization, it helps individuals and companies to work together to find better solutions to the challenges of the climate crisis.
To this end, Trellis regularly organizes conferences to promote professional exchange and expand networks between politics, business and scientists.
Trellis’ Greentech newsletter also supports the goal of knowledge transfer and networking. Over 50,000 subscribers – including executives from Google, Disney, Starbucks and Toyota – read the newsletter, which is primarily written by Richard Martin, Heather Clancy and Jim Giles.

The Greentech newsletter is ideal for a quick news overview with the latest events in the USA.
What’s special: Canary Media is an independent news portal that is financed exclusively through donations and reports on clean energy and solutions to tackle the climate crisis. By structuring it into individual areas, anyone interested – whether a journalist, politician or investor – can find the right news from the right area.

5. Bloomberg Green Daily
Bloomberg has been one of the most important and influential media houses in the financial and news sectors for decades. With the “Bloomberg Green Daily”, the editorial team has created a greentech newsletter. The climate journalists publish articles, analyzes and research. In the daily Greentech newsletter they provide insights into the consequences of global warming, present new technologies and introduce sustainable investments and companies.
In contrast to other Greentech newsletters, you need time to read: In addition to a detailed top story of the day, you get two further detailed analyses. In between there are short news headlines and additional Bloomberg articles. The reading time is between 10 and 15 minutes per issue. You get high-quality journalism that can’t just be skimmed quickly.
- Rhythm: Almost every day (except Sundays and public holidays)
- Format: Detailed analyses
- Language: English
6. The Spark
The sixth and last of the best greentech newsletters comes from the renowned knowledge magazine “MIT Technology Review”. Accordingly, “The Spark” is not an easy read, but rather, with its scientific contributions and in-depth specialist articles, it is aimed at interested specialist audiences who are looking for in-depth tech analyses. The newsletter aims to introduce technologies that can combat climate change.
Once a week on Wednesday mornings, MIT’s specialist journalists and scientists take up a current topic, a new study or research results, analyze them and arrange them in an overarching context. The contributions always come from the greentech spectrum but only ever reveal one storyline. That’s why “The Spark” is rather unsuitable for the daily thirst for knowledge and news updates.
- Rhythm: Weekly (every Wednesday)
- Format: Detailed analyses
- Language: English
How do you find the best greentech newsletter for you?
Greentech covers many topics – from new, sustainable technologies to drive models for cars to solar and wind energy solutions. Since the range is very large, we recommend that you subscribe to several newsletters so that you can find out which is the best greentech newsletter for you.
Depending on how much time you want to spend on newsletters and how you want your information to be served, there are different Greentech newsletters for you. To start with there would be a combination of UPDATE (your daily, German-language greentech update with news and a large analysis) and Canary Media Daily (daily, English-language news overview) and “The Spark“ (weekly, English-language analysis) makes sense.
How do the best greentech newsletters help you live more sustainably and discover future technologies early on?
Sustainability and digitalization are two of the central buzzwords of our society – this applies to everyday life as well as to business. A study of 1,695 German companies published in June 2025 by the Federal Environment Agency and the Federal Network Agency showed that over 75 percent of all German companies consider both topics to be “important” or “somewhat important”.
Particularly interesting: There is no representative of large companies who has classified sustainability as “unimportant”. When it comes to digitalization, less than ten percent find it “rather unimportant” or “unimportant”. The good thing: We can learn from the strategies of the largest and most important companies in Germany. They rely on greentech in order to remain competitive in the future.
That’s why it’s crucial for you to keep up to date with Greentech newsletters. Anyone who gets involved with sustainable technologies at an early stage can acquire knowledge that will become essential for their own career.
