Top 10 most sustainable software

1. Adobe


Net Zero by 2025.

– Committed to 100% of energy from renewable sources by 2035

 – More than 70% of our employees work in LEED-certified offices

– With our transition from a physical supply chain to a fully digital one, we’ve reduced the environmental impact of our products, including waste, by more than 95%. 

Adobe comes out ahead of the likes of Microsoft and Google because its climate commitments go well above and beyond considering the size of its company compared to others.

Adobe also shows great diversity in its actions, from net zero, to renewable energy, to supply chain. We’re impressed with where it is now, but also its ambition for the future.

Impressive commitments in every area

Adobe is truly one of the world’s leading companies when it comes to ESG, environmental impact, sustainability and overall CSR.

It’s not the only software company in the design and visual multi-media software category, with other impressive performers including Canva, as well as hardware organizations such as Sony.

Aiming to be net zero by 2025, Adobe is also committed to 100% of its energy to come from renewables by 2035, and has a wide range of commitments to reducing the impact of its environmental products.

2. Microsoft


– By 2030, we’ll be carbon negative, and by 2050, we’ll remove our historical emissions since our founding in 1975.

– By 2030, we’ll be replenishing more water than we use.

– By 2030, we’ll be zero waste across our direct waste footprint.

– We’ll protect more land than we use by 2025 and build a Planetary Computer.

Microsoft scores highly across all categories, especially their dramatic ambition to remove all their historical emissions by 2050, making them net positive throughout their history.

They’re also focused on water, waste and land.

3. Google (Alphabet)


– We’re decarbonizing our energy consumption so that by 2030, we’ll operate on carbon-free energy, everywhere, 24/7.

– Maximize the reuse of finite resources across our operations, products, and supply chains and enable others to do the same.

– We’ll replenish 120% of the water we consume by 2030, and we’re actively supporting water security and ecosystems where we operate.

– In 2007, became first major company in history to be carbon neutral.

Google is leading the charge when it comes to water and energy consumption.

They’ve also invested over 150 million in renewable energy, and made the largest corporate purchase of renewable energy in history.

4. Salesforce


– Accelerating the world’s largest businesses to net zero, sequestering 100 gigatons of carbon through conserving.

– Growing 1 trillion trees, protecting our oceans, and energizing the ecopreneur revolution.

– Salesforce has net zero residual emissions today. Our mission extends beyond our own operations to help the world’s largest businesses accelerate to net zero.

Driven by its six steps, Salesforce has a clear and tangible plan to tackle environmental issues. As one of the leading CRM platforms, it holds significant influence in the software space. Its six factors relate to both its own services and beyond.

Here are Salesforce’s six sustainability steps:

5. Dropbox


By 2030, Dropbox will:

– Achieve carbon neutrality in Scope 1 and Scope 2 emissions and in Scope 3 business-travel emissions

– Use 100% renewable energy for operations

– Fund organizations working for climate action

Dropbox’s attitude towards sustainability can be summed up by this quote from founder Drew Houston:

We have a responsibility to create a more sustainable and equitable world. The mission at Dropbox is to design a more enlightened way of working—and we’re committed to achieving our sustainability goals, investing in social-good initiatives, and being a force for positive change.

Dew Houston, co-founder and CEO Dropbox

6. Facebook (Meta)


– In 2021, we announced our goal to expand our net zero goal to include our value chain in 2030.

– Our climate program is aligned with the Science Based Targets initiative (SBTi) and guided by the latest science on what is necessary to transition to a zero-carbon future. We will continue to reduce our Scope 1 and Scope 2 emissions in line with climate science by increasing the efficiency of our operations and maintaining 100% renewable energy. 

– In 2020, we achieved net zero GHG emissions in our direct operations (Scopes 1 and 2) by reducing our emissions by 94% compared to 2017 levels.

Facebook is somewhat uniquely placed to tackle climate change, but not necessarily in the way they operate.

Facebook’s biggest impact is in tackling climate misinformation, and helping to educate the world. The ripple effect of that is impossible to quantify.

Here’s their statement on climate misinformation:

Software Sustainability Index 2023: Our conclusion

Sustainability and net zero goals are being pursued ever more aggressively by software companies around the world.

Their ability to act on their policies will affect the progress we’re all able to make in the fight against climate change.

Sustainability and ESG policies also affect:

  • Consumer buying decisions
  • Ability to attract and retain top talent
  • A mandate from the wider community
  • A trend to put pressure on other organizations, to tackle climate issues together.

With more and more companies achieving net zero, turning to renewables and creating more sustainable supply chains, software organizations will continue to influence the future of our planet.

We hope you enjoyed our Top 100 software sustainability index.
