Google reduces data center emissions, but supply chain continues to drive carbon footprint higher

illuminem summarises for you the essential news of the day. Read the full piece on ESG Today or enjoy below:

🗞️ Driving the news: Google has cut its data center carbon emissions by 12% in 2024 despite a 27% surge in electricity demand, thanks to record clean energy procurement and improved energy efficiency
• However, its overall carbon footprint grew as supply chain (Scope 3) emissions rose over 20%, driven by fossil-fuel-heavy manufacturing in supplier regions, according to its 2025 Environmental Report
• Google reaffirmed its ambitious 2030 goals — net-zero emissions across its value chain and 24/7 carbon-free energy (CFE) — but warned of growing challenges

🔭 The context: Google (see sustainability performance) was among the first major tech firms to commit to full hourly CFE matching, setting a high benchmark for climate action in the digital sector
• Rapid advances in AI and increasing cloud usage have driven electricity demand higher, pressuring companies to decarbonize faster
• Scope 3 emissions, which include supplier operations, are proving hardest to tackle due to regional disparities in clean energy availability and entrenched fossil fuel use

🌍 Why it matters for the planet: The findings highlight the dual challenge of scaling digital infrastructure sustainably while addressing upstream emissions in global supply chains
• Google’s progress underscores the potential of clean power procurement and efficiency gains but also signals that without systemic change in industrial regions, corporate climate targets may remain out of reach
• The report calls attention to the need for broader collaboration with suppliers, investors, and governments to decarbonize critical technology supply chains

⏭️ What's next: Google plans to accelerate supplier engagement through tools like its Energy Assessment Tool and Clean Energy Addendum, which asks suppliers to source 100% clean electricity by 2029
• The company is also investing in renewable projects in Asia-Pacific supply hubs, including a 1 GW initiative in Taiwan
• Continued deployment of advanced clean technologies, coupled with advocacy for enabling policies, will be key to aligning with its 2030 “climate moonshots”

💬 One quote: “We now have a better understanding of what it takes to get further down the path toward our climate moonshots — including what’s actually possible in different parts of the world,” — Kate Brandt, Google Chief Sustainability Officer

📈 One stat: Scope 3 emissions accounted for 73% of Google’s total carbon footprint in 2024, standing 25% above 2019 levels despite operational progress
