减少碳排放和气候变化
全球变暖应对措施的长期愿景
近年来，极端天气（干旱、热浪、大雨等）等气候变化造成的问题，以及传统上认为每 50 年发生一次的自然灾害越来越多，对世界许多地区造成了严重影响。除了加强业务连续性外，公司还需要在缓解和适应方面针对气候变化采取措施。在 2020 年 3 月，我们制订了全球变暖应对措施的长期愿景，并且正在努力减少我们的业务活动产生的温室气体排放（范围 1 和 2*）。
在受审查的财年中，与 2006 年 3 月 31 日结束的财年相比，CO2 排放量减少了 13.9%，实现了至少 10% 的目标，这主要得益于引入了可再生能源。除能源衍生的 CO2排放外，自 2006 财年以来，我们一直致力于通过引入燃烧和等离子体减排设备，来减少 PFC、SF6 与其他导致全球变暖的半导体制造气体的排放。
能源使用和碳排放趋势
我们正在开展节能活动，以实现中期目标，即"第 84 个财年（截至 2031 年 9 月 30 日）与第 74 个财年（截至 2021 年 9 月 30 日）相比，将单位能耗至少降低 10%。
在本财年，我们通过采取建筑节能措施和积极引进符合“领跑者计划”的设备，使单位生产能耗率比第 74 个财年降低了 16.4%，从而实现了至少 10% 的目标。
我们将继续推进节能和防止全球变暖活动。

可再生能源
滨松光子学株式会社正在努力通过推进太阳能和风能等可再生能源的实施来减少碳排放。在丰冈工厂，我们与太阳能公司合作，在 10 号楼的墙壁和屋顶上安装了太阳能发电设备 (250 kW)。在中央研究所的经营场所，我们将太阳能发电与小型风力发电相结合，为室外照明提供混合解决方案。截至 2022 年 10 月，我们累计实施了共 1,123 kW 的可再生能源。
2018 年 10 月，我们开始购买日本中部电力公司的“无二氧化碳电力”，扩大了可再生能源的引入。

对碳氟化合物排放控制法案的响应
修订后的碳氟化合物回收和销毁法于 2015 年 4 月颁布，旨在防止温室气体替代品泄漏导致的全球变暖。
我们通过为每个相关设备分配控制编号以及使用数据库管理该设备信息和检查记录， 来促进遵守此法律。我们对相关设备进行适当的简单检查和定期检查。当发现异常时，将尽快对设备进行维护和维修。我们使用数据库来保存检查历史记录等。根据数据库计算每个财年的泄漏量，并确认其低于 1,000 吨 CO2。
在处置相关设备时，我们遵守规定，要求从碳氟化合物回收操作员处收集并保存证书。
在每个事业部和业务场所，我们开展涵盖法律法规的教育活动，并为管理员提供内部管理方法。

减少温室气体排放
半导体制造中使用的 HFC、PFC、SF6 和 NF3 等温室气体具有很大的全球变暖潜力 (GWP)。我们正在努力通过安装、拆卸设备和优化流程来减少排放。
< 中长期目标 >
在 2030 财年，非能源温室气体排放量比 2013 财年减少 44%。
< 短期目标 >
在 2024 财年，非能源温室气体排放量比 2013 财年减少 28.5%。
