There is widely accepted scientific consensus that man-made carbon dioxide (CO2) emissions - largely by the use of fossil energy sources - contribute towards global warming. Lonza as part of the global industrial community is engaged in selecting and implementing energy efficient solutions and has set up its Community Practice in Energy (CoPE) project in late 2008 with the aim of saving 10 % of the annual energy costs over the 2007 baseline. While the CoPE project as such has been closed, it sparked a great number of energy efficiency ideas and initiatives, smaller and larger projects, which are realized stepwise in the course Lonza's site energy efficiency improvement programs. A significant amount of energy consumed today is still bound up with the release of additional, fossil-based CO2; implementation of novel energy efficiency measures, paired with the substitution of fossil fuels by e.g. steam generated by non-fossil sources, has the direct benefit of reducing man-made CO2 emissions to the atmosphere and fight the risk of climate change. The Lonza CoPE project and its succeccor programs was and is thus an important tool for sustainable development, benefiting the environment, economy and society.

Lonza Group reports under the Carbon Disclosure Project reporting scheme CDP and maintains two widely used customer-supplier web-hosted platforms to exchange sustainability profiles and emissions data (Ecovadis and Ecodesk).


Energy Efficiency

Examples of sustainable environmental quality in recent years include our Singapore site, where projects launched in 2016 will save an estimated 1.69 million kilowatt hours per year in energy usage. Our site in Porrino, Spain, added a new, pressurized condensates tank that has increased the yield of steam generation, reducing energy usage by an estimated 1.6 million kilowatt hours per year and cutting CO2 emissions by 723 tons. Our Rockland, Maine, site has made a concerted effort over the years and has sustainably reduced overall energy usage by 5% per year. Energy cost savings have nearly doubled the investments made in energy efficient equipment.


Solar Power

Waldshut - On the grounds of our former inorganic production site in Germany, disused in 1993 and since turned and reshaped into a growing business park, Lonza designed and constructed a photovoltaic power station on the south slope of the former industrial site’s remediated landfill. An innovative construction design developed in conjunction with a mountain cable car manufacturer allowed maximizing the solar yield while observing the requirement, that the surface seal of the remediated landfill needs to remain absolutely intact. 

Completed in 2008 the "Lonza Solar Park" proved its production stability in the years of operation since; delivering around 800 to 900 Megawatt-hours of electricity per year and offsetting around 750 metric tons of fossil based scope-1 CO2e emissions, if produced at a coal-fired power plant.

Singapore - A 181 kilowatt peak photovoltaic project was realized on the other side of the world at the Singapore-Tuas plant, where part of the roof was covered with solar panels. It replaces around 100 metric tons of fossil based scope-1 CO2e emissions annually and delivers clean electricity supporting the administration and laboratory building since its start-up. In 2009 this project received the Solar Pioneer Award of the Singapore Economic Development Board as well as the Greenmark Gold Award for New Buildings of the Singapore Building Control Authority.
