保护水资源
有效利用水资源
我们的中长期目标是，到 2030 财年单位销售额用水量较 2020 财年减少 10 %。
我们还致力于实现一项短期目标，即单位销售额用水量较上年减少 1 %。
2024 财年的结果（非合并）：
・较 2020 财年减少 12.0 %
・较上一年增长 13.3 %。
中期和长期目标均已实现，但短期目标尚未实现。
*计算范围：滨松光子学株式会社
我们认识到水资源的重要性，正在致力于减少用水量和使用再生水。在总公司工厂，用于生产纯水的水资源有一半由再生水供应，这使我们每年能够重复使用约 200,000 立方米的水资源。

*计算范围：滨松集团、国内合并子公司及海外合并子公司（截至 2023 财年，仅纳入制造场所。自 2024 财年起，非制造场所亦纳入计算。）
备注：本表中“自来水”和“工业用水”的总和对应 CDP 使用的“第三方水源”；本表中“井水”对应 CDP 使用的“地下水（可再生）”。
备注：本表中“河道排水”对应 CDP 使用的“地表淡水”和“地下水”的总和；“公共污水”对应 CDP 使用的“第三方目的地”。
滨松光子学株式会社根据日本法律及其自身标准，监控其所有工厂和研究设施的进水量和废水量。每个月，第三方分析组织都会进行废水分析，在最终排放口前面检测废水。如果发现异常值，我们立即努力确定原因并采取适当措施，严格遵守环境法律法规。
水风险评估和对策
滨松集团使用水风险评估工具“WRI Aqueduct”来评估日本和海外所有制造场所的水风险。截至 2025 年 1 月，我们确认所有国内场所均无重大水风险。
同时，中国的一处制造场所（北京滨松光子技术股份有限公司）的水风险较高。因此，我们对该场所用水情况进行了分析走访，并采取有效措施减少取水量。我们定期进行风险评估。
存在水风险的场所*：北京滨松光子技术股份有限公司（中国）
| 取水量 (1,000 立方米) | 废水 (1,000 立方米) | 用水量 (1,000 平方米) | |
|---|---|---|---|
| 2022 财年 | 34.1 | 18.7 | 15.4 |
| 2023 财年 | 34.2 | 18.0 | 16.2 |
| 2024 财年 | 39.2 | 22.5 | 16.7 |
*我们在此定义的水风险场所是经 WRI Aqueduct 评估“基线水压力”值为“高 (40-80 %)”或以上等级，且/或其“基线水资源枯竭”值为“高 (50-75 %)”或以上等级的场所。
除“WRI Aqueduct”外，我们还使用当地危险地图评估水风险，如“滨松市灾害预防地图”和“茨城数字地图”。
这些地图显示，位于天龙川附近的新贝工厂面临洪水威胁。作为应对措施，新贝工厂 2 号厂房安装了防水墙和浮力翻转防水板，减轻洪水损害。
此外，自 2016 年以来，滨松集团一直参与 CDP 水安全项目，报告我们集团的水风险及其应对措施。
对于地下水补给和森林保护的贡献
•地下水补给和森林保护
为了保护我们地区的地下水，滨松集团作为由磐田市环境保护促进委员会和当地地下水用户组成的委员会成员，参与了地下水补给和森林保护项目。这些项目的活动有助于为子孙后代维持地下水补给水平。2023 财年，我们参与了由该委员会发起的森林抚育间伐项目。
• 植树造林，防范潮汐
作为生物多样性保护和回馈当地社区的其他活动，滨松集团加入了静冈县政府主导的“滨松地区海堤计划”项下的“~KALA 海堤植树项目”。该项目旨在通过在海堤内陆一侧植树来减轻海啸造成的损害。自 2017 年以来，我们每年参加一次或两次活动，如植树和割草。
