Invisible Emissions – A forecast of tech supply chain emissions and electricity consumption.
The tech supply chain is a fast-growing but hidden source of carbon emissions. Consumer electronics suppliers account for more than three-quarters of the electronics industry’s total emissions. Greenpeace East Asia analyzed electricity consumption, carbon emissions and climate pledges of the biggest electronics suppliers in East Asia and forecast their emissions through 2030.
A forecast of tech supply chain emissions and electricity consumption
Consumer electronics suppliers, including semiconductor manufacturers, display manufacturers and final assemblers, account for more than three-quarters of the electronics industry’s total emissions. East Asia is home to key semiconductor manufacturers, and also has a significant number of display manufacturing and final assembly companies. Among all three industries, semiconductor manufacturing often requires higher electricity consumption.
The semiconductor industry is on track to overshoot the 1.5°C heating limit by more than double, even if companies meet their existing climate commitments.

Taiwan’s semiconductor manufacturing industry is likely to emit 22 million metric tons of CO₂e in 2027, higher than Alaska’s total emissions in 2020. TSMC is the largest semiconductor manufacturer in Taiwan and a major contributor to the industry’s emissions.
TSMC – Climate risk and action taken by the company
The climate crisis is causing more droughts, floods, and storms. TSMC’s infrastructure is at risk from climate change, especially in Tainan where flooding is likely because the land is below sea level. TSMC has pledged to achieve net zero emissions and 100% renewable energy by 2050. However, in 2021, only 9% of TSMC’s energy was renewable. To address this, TSMC plans to spend 6.8 billion TWD on purchasing renewable energy through RECs and PPAs. Despite being a leader in the industry, TSMC’s efforts to move towards renewable energy are not enough given the company’s large electricity demand.

Principles to follow for renewable energy procurement
Source renewables that have clear ownership of environmental attributes.
Procure renewable energy locally.
Prioritize newly commissioned renewable energy projects and set a commissioning date limit for old plants when doing procurement.
Adopt sourcing methods that can help increase new renewable energy installed capacity.
Therefore, recommend corporations to prioritize green electricity trading, onsite generation and equity investment, instead of unbundled Renewable Energy Certificates (RECs).
Emissions from the global semiconductor industry are skyrocketing.
Based on projected market size and existing climate commitments from semiconductor manufacturers, the semiconductor manufacturing industry is on track to consume 237 terawatt hours (TWh) of electricity globally in 2030, close to Australia’s 2021 electricity consumption.
The industry is projected to emit 86 million metric tons of carbon dioxide equivalent (CO₂e) in 2030, more than Portugal’s total emissions in 2021.
Zero semiconductor manufacturers, display manufacturers, or final assembly companies included in the study have issued climate commitments that are in line with limiting global warming within 1.5 degrees Celsius.
Electricity consumption by TSMC, Taiwan’s semiconductor manufacturing giant, is on track to grow 267% by 2030, the biggest increase of all semiconductor manufacturers in East Asia.
By 2030, TSMC is on track to consume as much electricity as roughly one-fourth of Taiwan’s population.
In 2021, renewable energy comprised only 9% of TSMC’s total energy usage, far lower than renewable energy usage rates of the chipmaker’s biggest rivals.
Electricity consumption from Taiwan’s semiconductor manufacturing industry as a whole is on track to increase 236% between 2021 and 2030. By 2030, semiconductor manufacturers in Taiwan will consume twice as much electricity as did New Zealand in 2021, according to the forecast. The increase is due in large part to TSMC’s growing electricity consumption. By 2030, about 82% of Taiwan semiconductor manufacturing electricity’s consumption is projected to come from TSMC.
Besides TSMC, only two other companies studied, Luxshare Precision and SK Hynix, are projected to see electricity consumption growth by 2030 that exceeds 200%. Between 2021 and 2030, Luxshare Precision and SK Hynix’s electricity consumption is forecast to increase 270%, and 227%, respectively.
By 2030, Samsung Electronics’ semiconductor manufacturing emissions will exceed those of any tech suppliers studied, at 32 million metric tons of CO₂e per year.
Samsung Electronics is South Korea’s largest semiconductor manufacturer. The company’s electricity consumption from semiconductor manufacturing is projected to reach 55 TWh by 2030, higher than Singapore’s national electricity consumption in 2020. However, Samsung has been slow to transition to renewable energy in South Korea.
In 2022 nearly 75% of Samsung Electronics’ electricity consumption took place in South Korea. However, Samsung has not issued a 2030 climate commitment for its operations inside South Korea.
Emissions from South Korea’s semiconductor manufacturing industry are projected to rise through 2029 due in large part to Samsung Electronics’ continued emissions growth.
South Korea’s semiconductor manufacturing industry is projected to consume 71 TWh of electricity by 2030, a 145% increase from 2021.
Emissions from Samsung Electronics, Samsung Display, and Luxshare Precision are on track to increase through 2030, long after emissions from other companies peak.
Emissions from Samsung Electronics, Samsung Display and Luxshare Precisions are not likely to peak before 2030 because all three companies lack 2030 targets.
It is essential that tech companies issue climate targets that are effective by 2030 to ensure that their emissions peak in line with a 1.5 degree Celsius heating limit.
Renewable Energy Certificates (RECs) accounted for 84% of all renewable energy sourced by the semiconductor manufacturing industry in 2021.
RECs are financial instruments that represent existing renewable energy projects. The purchase of RECs does not add any new renewable energy to the grid. For this reason, RECs are one of the least impactful forms of renewable energy procurement.
Instead of purchasing RECs, semiconductor manufacturers should purchase renewable energy with addictionality through Power Purchase Agreements (PPAs), onsite generation and investment.
In Taiwan, for example, large electricity consumers like TSMC have bought up the majority of existing RECs instead of constructing their own renewable energy infrastructure. TSMC dominates Taiwan’s electricity market and should pursue carbon neutrality by building onsite solar and investing in renewable energy power stations, rather than through the purchase of RECs.
Business as usual: The company fails to take actions to meet its climate commitments
Commitments delivered: The company’s existing commitments are fully delivered
1.5-degree aligned: The company’s commitments and actions are consistent with 1.5 degrees
