"Our experience of working together with Four Elements and the outcome of the project markedly exceeded our expectations. The company demonstrated high professional expertise in conducting Life Cycle Assessment and was receptive to addressing all the concerns while following the best industry practices to the letter; it went "above and beyond" to compare the obtained results with the published information on the similarly functioning products. The project was completed on schedule and on budget. The completed LCA was peer reviewed with only minor modifications. We will collaborate with Four Elements again.”
"We have been working with Annie Landfield Greig since the late 1990’s, when we first started doing LCA. Since then, she has also carried out our Corporate Greenhouse Gas Inventory, product carbon footprints, and LCAs for the Environmental Product Declarations of many of our product lines. Four Elements demonstrates competency in Life Cycle Management projects of every scope and size, and has consistently produced on-time and within-budget deliverables."
“I have been associated with Four Elements in LCA-related workshops, expert panels, and other LCA activities for almost 15 years. Over that time, Annie Landfield Greig has demonstrated her expertise and the ability to perform LCA-related tasks in a timely and effective manner. Four Elements has participated in workshops convened by EPA, has worked as a consultant to NIST on the BEES and BIRDS tools, and is closely associated with the American Center for Life Cycle Assessment (ACLCA), among other high profile undertakings.”
"We employed Four Elements to conduct a critical review of an internally developed LCA tool. It was a true pleasure to work with Annie Landfield Greig. Her thorough assessment of the tool and her subsequent guidance led to significant improvements and simplifications of the tool – and we're still using it."
"Four Elements worked with our organization on Life Cycle Analysis (LCA) about four years ago. During this time, Four Elements provided us with experienced and insightful service in our initial work on LCA of our products. The detailed effort helped us to interpret and understand the relevance of LCI/ LCA to our business."
“If you're looking to perform an LCA the right way - accurate, thorough, and fitting - contact Annie Greig. If you'd prefer to slide through just to get the LCA over with, don't. Annie is both experienced and practical. A thoroughbred in the LCA arena. Mannington Mills has worked with Annie going back to 2007 when she established much of our first set of Life Cycle Assessments. Along with creating the LCAs, Anne’s experience and guidance also helped us appreciate the insight that an LCA can provide. Our experience with Anne has always been positive. She is flexible, knowledgeable and responsive.”
"Annie Landfield Grieg has provided life cycle modeling skills for many bio-based product studies for Omni Tech which have successfully passed external peer reviews. She has also been efficient in entering newly modeled data into international databases and knows how to find datasets for a multitude of modeling inputs. Her clear writing and analytical skills contributed to performing successful comparisons which were accepted by international experts. She is also knowledgeable in several life cycle impact models."
