Microsoft aims for carbon negative by 2030. Apple claims carbon neutrality across their entire business and supply chain by 2030. Google says they’ve been carbon neutral since 2007 and wants to run on 24/7 carbon-free energy by 2030.

These all sound impressive. They’re not directly comparable. The targets differ in scope, ambition, and how achievable they actually are. Here’s how to decode what these commitments actually mean.

The Terminology Matters

Carbon neutral means net zero emissions – you’re emitting carbon but offsetting an equivalent amount through credits or removal.

Carbon negative means removing more carbon than you emit. You’re net negative.

Net zero is similar to carbon neutral but usually implies actual emissions reduction rather than heavy reliance on offsets.

24/7 carbon-free energy means every hour of the day, your energy consumption matches with carbon-free generation. This is way harder than annual matching.

Companies use these terms semi-interchangeably, which creates confusion. The devil is absolutely in the details.

Scope 1, 2, and 3

This is critical for understanding what’s actually included:

Scope 1: Direct emissions from sources the company owns or controls (company vehicles, on-site fuel combustion).

Scope 2: Indirect emissions from purchased electricity, steam, heating, cooling.

Scope 3: All other indirect emissions in the value chain – suppliers, product use, employee commuting, business travel, waste, etc.

For tech companies, Scope 3 is usually 75-95% of total emissions. A commitment that excludes Scope 3 is missing most of the actual carbon impact.

Apple’s commitment includes Scope 3. That’s genuinely ambitious. A company claiming carbon neutrality for only Scope 1 and 2 is doing something much easier and less meaningful.

The Baseline Year Games

Net zero by 2030 sounds great. But from when? If you measured your baseline in a high-emissions year, you can show big reductions even while growing emissions in recent years.

Some companies picked 2019 as their baseline, conveniently before pandemic reductions. Others use earlier baselines when they were smaller.

The choice of baseline can make the math look a lot better or worse. Always check what year they’re measuring from and what’s changed since then.

Offsets vs. Actual Reduction

You can achieve “net zero” entirely through offsets while increasing your actual emissions. That’s technically meeting the target but arguably missing the point.

The best commitments show:

• Absolute emissions reduction over time
• Offsets as a decreasing percentage of the total
• Investment in carbon removal for genuinely unavoidable emissions

Microsoft’s carbon negative commitment includes removing all their historical emissions since founding. That’s ambitious. Most companies aren’t going nearly that far.

The Energy Matching Problem

Google’s 24/7 carbon-free energy goal is harder than it sounds. Many companies claim 100% renewable energy, but they’re doing annual matching – they buy enough renewable energy credits to match their total consumption, but they’re not necessarily using renewable energy at every moment.

If you’re running data centres at night when solar doesn’t work, you’re still drawing from the grid, which might be fossil fuels. Annual matching means you buy enough solar credits to offset that, but the actual electrons powering your servers at 2am might be from coal.

24/7 matching means having carbon-free power every hour. That requires either on-site generation, storage, or specific contracts with energy providers. It’s way more complex and expensive.

Google’s working on this. As of 2026, they’re around 70% of the way there in their best regions. It’s progress, but not done yet.

Supply Chain Challenges

Including Scope 3 means taking responsibility for your suppliers’ emissions. For a company like Apple, that’s hundreds of suppliers manufacturing components globally.

You can’t directly control their emissions. You can:

• Require carbon reporting from suppliers
• Prioritize lower-carbon suppliers in purchasing decisions
• Invest in helping suppliers reduce emissions
• Exit relationships with non-compliant suppliers

This is hard and expensive. Apple’s actually doing this work – they’ve invested in renewable energy projects for suppliers and set requirements.

Most companies talk about engaging suppliers but don’t show concrete results. Check for actual numbers on supplier emission reductions, not just pledges.

The Product Use Problem

For tech companies, product use is a huge part of Scope 3. Every iPhone, laptop, data centre server – they consume energy during use, usually for years.

You can design more energy-efficient products (good). You can estimate the carbon impact based on average grid mix where products are sold (reasonable). You can claim credit for renewables even though individual users are on the grid (questionable).

The accounting here gets fuzzy. Different companies measure this differently, making comparisons difficult.

Credibility Indicators

When evaluating a tech company’s net zero commitment, look for:

Third-party verification: Is anyone independent checking their math? The SBTi (Science Based Targets initiative) provides credible validation.

Interim targets: Commitments for 2050 are easy to make because nobody’s accountable. Look for 2025 or 2030 targets with actual checkpoints.

Transparent reporting: Annual sustainability reports with detailed emissions data, broken down by scope, with methodology explained.

Declining total emissions: Not just intensity (emissions per dollar revenue), but absolute emissions going down.

Offset quality disclosure: What types of offsets? What verification standards? Declining offset use over time?

The Cynical Take

Net zero commitments are marketing. They look good to investors and customers while requiring minimal near-term action.

2030 or 2050 targets won’t be achieved by current leadership. There’s no accountability. Companies can quietly revise targets later.

Most commitments are heavy on offsets and light on actual operational changes. It’s greenwashing with extra steps.

The Optimistic Take

Even imperfect commitments create accountability and drive investment in solutions. Public targets create pressure for progress.

Companies competing on sustainability push the whole industry forward. Tech giants investing in renewable energy and carbon removal create markets that help scale these solutions.

Imperfect action now beats perfect action never. The commitments are meaningful if they’re followed by genuine effort.

What Actually Matters

The specific target year matters less than the trajectory. Is the company actually reducing emissions year over year? Are they investing in solutions beyond offsets?

The scope matters. Scope 3 inclusion is the difference between genuine ambition and limited effort.

The transparency matters. Can you verify their claims? Are they showing their work?

Some tech companies are doing real work here. Others are making impressive-sounding commitments that fall apart under scrutiny.

The Bottom Line

Don’t just read the headline commitment. Check the details: what’s included, what baseline they’re using, how much is offsets versus reduction, what interim targets exist.

Net zero commitments can be genuinely ambitious climate action or essentially meaningless PR. The difference is in implementation, not the target year.

Most tech companies are somewhere in between – making real progress in some areas while relying heavily on offsets in others.

The key question: are emissions actually going down, or is the company just getting better at accounting tricks while their carbon impact grows?

For some companies, it’s the former. For too many, it’s the latter.
