Tougher environmental standards and higher expectations for health and wellness are among the powerful global trends influencing our customers' growth and their focus on the sustainability of their products and operations. At Grace, we share this focus. Our focus on helping our customers meet these demands, and to meet them ourselves, is based on our view that prosperity and sustainability go hand in hand.
The value we deliver through customer-driven innovation increasingly is based on how we help our customers meet their sustainability goals. Grace products and technical services improve the efficiency of our customers' processes, reduce energy or water use, cut harmful emissions, conserve material inputs, and reduce waste. Our technologies enable our customers to make products that meet the toughest environmental standards or to reformulate products to address rising consumer and regulatory expectations for sustainability, human health, and safety. The products in our portfolio that address these sustainability endpoints accounted for approximately $1 billion or 38 percent of total revenue in 2018.
Grace also delivers value through operating excellence, continually tracking progress toward our goals of no one hurt, nothing out of place, and no harm from our products. The discipline of continually improving the efficiency and performance of our manufacturing and integrated supply chain is deeply embedded in our culture and annual operating plans.
At the heart of all we do around the world, are the people of Grace. We have a high-performance culture focused on creating value for our customers and investors. This commitment to value creation extends to our other stakeholders. We are active members of the communities where we operate and remain committed to the highest standards of integrity and respect for our stakeholders and for one another.
We invite you to explore these and other dimensions of our social responsibility beneath the broad umbrella of Sustainability.
