Reduction of CO2 emissions

Tamron is reducing CO2 emissions in its business to realize a decarbonized society. In July 2020, Tamron reviewed its basic unit targets up to now, changed it to a target of reducing CO2 absolute amount by 30% in 2030 by 30% compared to 2015. For the achievement the goal, we also set single year target of 2% reduction in 2020 by backcasting that goal.

Breakdown of CO2 emissions

CO2 accounts for most of the greenhouse gases released by Tamron. As regards the sources of CO2 emissions(excluding distribution and logistics), electricity usage accounts for 98%, followed by heavy oil at 1%. Given this mix, our energy saving activities focus on


Change in CO2 emissions

CO2 emissions have remained largely flat since FY2014. In FY2019, CO2 emissions fell by around 0.56% compared with FY2018 by volume, marking an improvement. On a per-site basis, emissions decreased 4.1% domestically, while operation improvement of air conditioner and solar power generation helped Tamron Optical (Foshan) in China achieve a 2.1% reduction. On the other hand, emissions rose 4.0% at our plant in Vietnam, which has seen an increase in manufacturing models.
In FY2020, we will make reductions through equipment replacements and process improvements at each site, and work on comprehensive energy measures taking into account the external purchasing of renewable energies.


Ascertaining CO2 emissions in the supply chain (Scope3)

In order to realize a low-carbon society, not only activities within Tamron but also efforts throughout the supply chain including upstream and downstream are important. To promote our efforts, we have grasped indirect greenhouse gases (Scope 3) related to business activities in the supply chain.

Ascertaining CO2 Emissions in the Supply Chain (FY2019)

Initiatives to Reduce CO2 emissions

In FY2019, we used simplified electric power measurement devices to identify surplus power not only in Japan but also Tamron Optical (Foshan) in China . When possible, we implemented reduction measures such as operational improvements and confirmed the effects. Solar power generating systems have been installed at Tamron Optical (Foshan) in China and Tamron Europe (Germany). FY2019 generating capacity was 311,000 kWh at Tamron Optical (Foshan), representing a reduction effect of 171 tons of CO2. At Tamron Europe, 67,000 kWh were generated with a reduction effect of 47 tons of CO2. In addition, at the head office, which was constantly switching to LED, the reduction effect was 16t.

The third Friday of every month has been designated as No My Car Day, and certain days in the summer and winter are designated as Eco Life Days (an initiative launched by Saitama Prefectural Government). In FY2019, Tamron's ongoing Eco Life Days activities were recognized by Saitama Prefecture with the receipt of a letter of appreciation. CO2 emissions were reduced by 12.4t-CO2 through these efforts in 2019.
