TSMC says information and communication technology products built on its chips saved the world more than 180 billion kWh of electricity and cut close to 89 million metric tons of carbon emissions in 2025, citing an ITRI estimate. The company has also aligned with SBTi absolute emission-reduction targets and set a 2030 goal of saving nearly 7 kWh globally for every 1 kWh it consumes making semiconductors.
How much energy and carbon did TSMC chip-powered products save last year?
Information and communication technology products using TSMC chips saved the world more than 180 billion kWh of electricity in 2025CITE:E1. The same products cut carbon emissions by nearly 89 million metric tons over the same periodCITE:E2. TSMC Chairman C.C. Wei cited an estimate from the Industrial Technology Research Institute (ITRI) covering six major smart application fields to support these figuresCITE:E9.
| Metric | Value | Period |
|---|
| Electricity saved by ICT products using TSMC chips | Over 180 billion kWh | 2025 |
| Carbon emissions avoided | Nearly 89 million metric tons | 2025 |
| Global electricity savings per 1 kWh TSMC consumes | Nearly 7 kWh | Target by 2030 |
What is TSMC's emission-reduction target for 2030 and beyond?
TSMC has set a goal that by 2030, each kilowatt-hour of electricity it uses to produce semiconductor products will save the world nearly 7 kWhCITE:E3. TSMC restated this same 2030 electricity-savings ratio separatelyCITE:E10. This year, TSMC aligned its roadmap with the Science Based Targets initiative (SBTi) absolute emission-reduction targets to advance its net-zero pathwayCITE:E7.
How has sustainability become part of TSMC's core strategy?
TSMC Chairman C.C. Wei said the company is increasing its allocation of profit-distribution resources toward sustainabilityCITE:E4. Wei made the statement as TSMC released its fiscal year 114 (2025) sustainability reportCITE:E8. Wei said the company is investing across generations in ESG initiatives and working with stakeholders to drive shared benefit for societyCITE:E4. Wei added that for TSMC, sustainability is an expression of operational resilience, competitiveness, and long-term value, and that realizing this vision depends on every TSMC employee applying technology, expertise, and passion to bring positive changeCITE:E11.
What power challenges and opportunities does TSMC face in the AI era?
Wei said electricity drives token output, and tokens create intelligence, which brings enormous opportunity alongside a steep low-carbon transition challengeCITE:E5. Separately, the International Court of Justice issued a milestone advisory opinion establishing that countries have legal obligations to address climate change, marking the first time climate responsibility has formally escalated to legal responsibilityCITE:E6.
What this means
TSMC's 2025 figures describe two different things: downstream savings its chips already deliver to the products that use themCITE:E1CITE:E2CITE:E9, and a forward-looking 2030 ratio target plus SBTi alignment for TSMC's own production footprintCITE:E3CITE:E7CITE:E10. Wei's framing ties both to the same pressure point — AI-driven token output raises electricity demand even as the ICJ has just formalized governments' legal duty to act on climate changeCITE:E5CITE:E6, which is the backdrop against which TSMC frames sustainability as resilience, competitiveness, and long-term valueCITE:E11.

The two numbers TSMC leads with — 180 billion kWh saved and 89 million tons of carbon avoided — measure what happens downstream, in products that use its chips, not TSMC's own factory footprint. Its own commitments sit on a separate track: aligning with SBTi absolute reduction targets this year and a 2030 goal of returning nearly 7 kWh globally for every 1 kWh it consumes to make chips. Those are different accounting boundaries, and conflating them would overstate how much of the 2025 result is TSMC's own emissions reduction versus product-efficiency spillover. The indicator worth watching next is whether TSMC's future sustainability reports disclose actual progress against the SBTi absolute targets themselves, rather than repeating the downstream product-savings estimate — that is the number that will show whether the 2030 ratio goal is on track.
