保护我们的水资源
有效利用水资源
滨松光子学设定了“支持到 2030 财年，每个销售单位的用水量比 2020 财年减少 10%”的中长期目标，以及“支持每个销售单位的用水量与上年相比减少 1%”的短期目标。
2023 财年的结果（非合并）：
・比 2020 财年减少 22.4%
・与上年相比增长 1.3%
中期和长期目标已实现，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，致力于减少水资源的使用，并对所使用的水进行回收利用。我们在内部开展节水活动。我们在总公司工厂引入了系统，以便从回收利用的水中获取在纯水制造中的一半用水量。如今，我们每年回收 200,000 m3 的水。

备注：CDP 水使用的“第三方水源”一词适用于“自来水”和“工业水”的总量，CDP 水使用的“地下水（可再生）”适用于“井水”。
备注：CDP 水使用的“河流排放”适用于“地表淡水”和“地下水”总量，而 CDP 水使用的“第三方目的地”适用于“公共下水道”。
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，我们立即承诺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
滨松光子学株式会社使用水风险评估工具“WRI Aqueduct”来评估日本和海外所有生产基地的水风险。截至 2024 年 1 月，我们确认所有国内生产场所均无重大水资源风险。
除“WRI Aqueduct”外，我们还使用当地危险地图测量风险，如“滨松市灾害预防地图”和“茨城数字地图”。因此，我们认识到，如果 Tenryu River 发生洪水，新贝工厂将会淹没。因此，在新贝工厂 2 号新楼，我们正在采取防洪措施，如安装防水墙和浮力掀起式防水板。
此外，自 2016 年以来，滨松光子学一直参与 CDP 水安全，我们报告了我们的水风险和应对措施。
对补充地下水和保护森林的贡献
• 补充地下水和保护森林
为了保护其本国地区的地下水，滨松光子学株式会社和地区地下水响应委员会共同主办了定期的地下水补充和森林保护活动。我们作为理事会成员参与这些活动，该委员会由磐田市环境保护促进委员会和周边地区的地下水使用者组成。这些努力的目的是通过种植健康的森林，维持地下水的补充水平，为子孙后代保护丰富的水资源。2023 年，我们参加了由地区地下水响应委员会赞助的旨在补充地下水的当地森林稀疏化活动。
• 植树造林，防范潮汐
作为保护生物多样性和为该地区做出贡献活动的一部分，我们参与了“~KALA 项目”。“~KALA 项目”是一个在海堤内陆侧种植树木保护站的项目，旨在减轻海啸造成的损害。这项工作是作为由静冈县政府领导的滨松地区海堤计划的一部分发起的。自 2017 年以来，我们每年参加一次或两次活动，如种植树木和割草。
