Dr. Erik Lindqvist, PhD

Environmental scientist translating ecological data into actionable carbon and sustainability metrics for researchers and the public.

Dr. Erik Lindqvist is a Stockholm-based environmental scientist whose work centres on quantifying the ecological costs of human activity, from household energy consumption to large-scale industrial land use. At IVL Swedish Environmental Research Institute, he leads a programme that develops standardised methodologies for carbon accounting and ecosystem services valuation, with results cited in Swedish national climate policy briefings and several EU-funded Horizon Europe projects. His doctoral research at Stockholm University produced a widely referenced framework for attributing greenhouse gas emissions across complex supply chains, a method now embedded in tools used by Nordic municipal authorities.

Over fourteen years Lindqvist has become recognised for bridging rigorous academic ecology with practical decision-support. He contributed to Sweden's first nationally harmonised biodiversity impact database and has advised companies such as Vattenfall and Ericsson on aligning their sustainability disclosures with Science Based Targets initiative (SBTi) criteria. At the Stockholm Resilience Centre he collaborated on planetary boundaries research, applying quantitative tipping-point models to regional land and water systems. This combination of field ecology and computational modelling gives his work an unusually concrete empirical grounding.

On OnlyCalculators, Lindqvist authors and reviews tools covering ecology, carbon and energy footprint, and sustainability metrics. Each calculator he stewards draws directly on peer-reviewed emission factors, authoritative datasets, including IPCC AR6 values, the Ecoinvent life cycle inventory database, and IEA energy statistics, and is cross-checked against the underlying literature before publication. He is particularly focused on making the assumptions behind each calculation visible to users, so that a student estimating a semester's carbon footprint and a procurement analyst sizing a supplier's Scope 3 emissions are both working from the same defensible numbers.
