Climate Change

The threat from global warming extends beyond rising sea levels. Warmer climates will lead more hot and humid environments, allowing mosquitos to spread diseases to warm climates. Countries with drier climates will suffer from forest fires of an even greater scale. Released by the World Economic Forum, The Global Risks Report 2021 evaluated critical topics relating to the economy, environment, technology, and public health. The Report assessed related impact and the likelihood of impact, and explained the future risks of stakeholders. The top seven global risks are all environmental. The first is extreme weather events, followed by climate action failure and then natural resource crisis. The ranking shows that climate change remains the topic of greatest concern to global experts and decision makers.

HIWIN is tackling climate challenges head on, employing a project-based approach to analyze risks and evaluate processes. We were able to identify risks in our process equipment and tap water system. We also recognized a growing number of natural disasters and decided to strengthen our climate resiliency to ensure we can recover as quickly as possible to minimize damages after climate disasters.

Our Climate Change Responding Journey

Targets relating to climate risks and opportunities focus on mitigation and adaptation measures. We have also laid down strategies to help us meet our short-, mid-, and long-term targets. In 2021, we decided to employ the TCFD framework to evaluate our climate risks and opportunity, formulating adaptation action plans based on our level of exposure and vulnerability matrix. We then identify significant risks and opportunities and conducted climate risks analyses for laws and regulations, markets, and production to evaluate potential financial impacts.

To ensure HIWIN is saving energy and reducing carbon emissions, we have commission an impartial third party each year to verify our compliance with ISO 14046:2018. In 2021, we disclosed our carbon emissions, carbon reductions from management measures, and related risks and opportunities in response to the CDP. To strengthen our green competitiveness, we remain dedicated to reducing GHG emissions and have set targets to minimize the impact from climate change.

Financial Impact from Climate Risks

Type Item Climate Risk Scenario Timeline Potential Financial Impact Measures/Action Plans
Transition Risks Policy & Regulations Rising GHG emissions costs
  1. In Taiwan, a new carbon pricing scheme was proposed. Once approved, the carbon pricing scheme will be levied on companies annually based on Scope 1 emissions (refrigerants, gas, diesel, etc.).
  2. HIWIN has established energy conservation targets to reduce carbon emission in compliance with national targets (for Scope 1 + Scope 2 emissions). The annual carbon reduction target is 1% less than the previous year, we estimate that we may exceed regulatory emissions levels by 2025 and possibly face penalties.

Energy Conservation, Carbon Reduction, and Green Living

Energy Conservation, Carbon Reduction, and Green Living advocating for limited energy consumption in the summer, water conservation, environmental education videos, environmental protection point collection event, and no plastic programs. In 2022, we expect participations rates to reach 80%.

Employees watching a video on environmental protection

A total of 152 employees and their families enjoyed Beautiful Formosa and The Midnight Sky together with HIWIN, pledging to take action and protect this land. 80% of employees that watched the videos felt that they learned more about Taiwan's incredible ecosystems; 95% of employees said that would start to pay more attention to environmental protection; and 45% of employees were inspired to join environmental protection campaigns (e.g. beach cleanups, ocean cleanups, tree planting, etc.)

Environmental Protection Point Collection Campaign

We encourage employees to practice green consumerism and learn more about environmental protection. To such ends, we launched an environmental protection point collection campaign that would introduce employees to green living and select eco-friendlier options. We hope the campaign can instill green consumerism into our employees' daily lives to further minimize the wasting of resources and mitigate environmental impacts. We launched the campaign in September 2021 and a total of 166 employees participated. We will continue to hold the environmental protection point collection campaign every year as we believe that it supports environmental protection and can also introduce employees to eco-friendly products, which makes it all the more meaningful.

Adopt-A-Tree Program

Trees can absorb carbon and are, therefore, recognized as our best allies against climate change. In 2016, HIWIN signed up for Yunlin Technology-based Industrial Park's Adopt-A-Tree Program. We now manage over 4,000 square meters of public facilities. In 2019, we also signed up for Taichung Industrial Parks' Adopt- A-Tree Program, adopting 54 street trees that HIWIN employees will care for, e.g., weeding, fertilizing, pest control, trimming, and overall maintenance.

No Plastic Program

Limiting plastic use is key to mitigating global warming, therefore, we must reduce our use of single-use plastics. In 2021, to support the Environmental Protection Administration's Marine Debris Action Plan, HIWIN banned the use of single-use plastics at HIWIN cafeterias. Employees are now required to prepare their own utensils and containers, which will help reduce 200,000 plastic bag waste. Using 1 plastic bag generates 0.057kg of carbon emissions. The reduction of 200,000 plastic bags reduces 114,000 metric tons of carbon emission each year. (EPA-Lowarbon Campaign Platform announced that 1 plastic bag generates 0.057kg in carbon emissions)

No Plastic Program

Advocating the No Plastic Program

GHG Inventory & Reduction

HIWIN has instituted policies, asking all production locations to inventory GHG emissions in compliance with EPA's guidelines and regulations, IPCC 2007's GWP, and the EPA's emission coefficient. The inventory has to be verified by a third party each year and the boundaries are to be defined by operating authorization.

We chose 2020 as the base year because we believe HIWIN's data from 2020 are more representative of our operations and more sound.

Carbon Reduction Milestones & Targets

According to outcomes from our GHG inventory, indirect Scope 2 emissions from purchased electricity accounts for 93.76% of total HIWIN emissions. To meet reduction targets, we have assembled a Management & Review Committee to track carbon reduction progress using emission intensity as the primary indicator. In the future, we will continue to roll out ISO 50001 energy management systems to help us conserve energy and maintain equipment, which can help further reduce carbon emissions from manufacturing processes.
