Greenhouse Gas Emissions

With the challenges caused by global climate change, enterprises must reduce greenhouse gas emissions during operations to mitigate the negative impact on the climate. Wistron implements greenhouse gas inventory in accordance with ISO 14064-1 every year. We also appoint a third-party impartial inspection institution to conduct verification in order to rigorously monitor greenhouse gas emission sources and volume in all plants. In response to the requirements of the Science Based Targets initiative (SBTi), the evaluation plan for Scope 3 Greenhouse Gas Emissions was implemented. The aim was to include broader upstream and downstream indirect emissions into our own greenhouse gas reduction scope. We hope to utilize Wistron's influence and work towards the target of 1.5℃ of the Paris Agreement together with the world.
