Interface ESG Overview Our Climate Commitment Climate Take Back™ is our commitment to reversing global warming and creating a climate fit for life. We have set a goal to reduce our CO2 emissions across our company and supply chain by 2030 with a target validated by the Science Based Targets initiative. • Reduce absolute Scope 1 and 2 GHG emissions 50% by 2030 from a 2019 base year • Reduce absolute Scope 3 GHG emissions from purchased goods and services 50% and from business travel and employee commuting 30% by 2030 from a 2019 base year Every flooring product that we sell – carpet tile, LVT, and rubber sheets + tiles – is third-party verified Carbon Neutral across its full lifecycle. We introduced the world’s first carbon negative carpet tile, measured cradle-to-gate, with our CQuest™BioX backing. 25

Interface ESG Overview Significant Reductions in Environmental Impacts from Operations 96% 88% 48% 75%76% 92% Fewer greenhouse gas emissions* Less water used to make products* Of materials in the flooring products we sell are from recycled or bio-based sources Smaller cradle-to-gate product carbon footprint * Less waste sent to landfills* Renewable energy used at carpet and rubber manufacturing sites Learn more about our environmental impacts here. 26

Interface ESG Overview All Interface Flooring is Carbon Neutral or Carbon Negative All of the flooring products we sell - carpet tile, LVT and rubber - are carbon neutral across their full product life cycle through our third party verified Carbon Neutral Floors™ program. 27 Supporting Carbon Offset Programs Around the World To compensate for the full life cycle carbon emissions that we are unable to eliminate, we purchase carbon offsets. We source offsets only from projects that meet third-party verified carbon offset standards to assure that the carbon credits we use are real (have happened), additional (beyond business-as-usual activities), measurable and permanent. The types of projects that we support include: • Renewable energy projects from solar and wind power in Asia-Pacific, as well as forest projects for reestablishments of native forest, conservation, and the protection of biodiversity • Forest protection programs in Africa, alongside community fuel switching and water purification projects tackling carbon emissions while promoting human health and community empowerment • Reforestation projects in the Americas to keep carbon stored and sequestered in the soil and plants • We have sold 419 million sq meters of carbon neutral flooring globally since 2003 • We have retired 5.7 million metric tonnes of verified emission reduction credits since 2003

Interface ESG Overview The First Cradle-to-Gate Carbon Negative Carpet Tile 28 Our carpet tile materials are engineered to have a negative carbon footprint during the embodied carbon phase of the carbon life cycle. Guided by materials science, we’ve incorporated innovative new materials to our carpet tile: • Bio-based materials that would otherwise release unwanted carbon store it within our backings, preventing its release • Recycled content materials in our backings and face fiber Materials coupled with our improved manufacturing creates a product with a negative embodied carbon footprint. We do not control the operational carbon phase so we offset the impact of this phase by supporting projects such as reforestation and renewable energy.
