Energy Efficiency Movement
Insights

The Knowledge Hub helps organizations answer the practical “how” of energy efficiency: where to start, what solutions exist, how to build the case and how to overcome implementation barriers.

We curate reports, guidance, case studies, training and real-world solutions to help companies move faster from ambition to implementation. We don’t have all the answers, but we’re committed to identifying and sharing solutions for greater energy efficiency and faster emission reductions.

Here are our latest findings, available guidelines, and standards.

Guidelines

The Carbon Disclosure Project, Science-Based Targets, and the Greenhouse Gas Protocol frameworks provide essential guidance to align your goals with global sustainability standards.

GHG

The Greenhouse Gas Protocol

A globally recognized standard for measuring and managing greenhouse gas (GHG) emissions. It provides clarity on how organizations can measure and report their emissions, supporting sustainability efforts. GHG Protocol develops guidance to address specific sectors’ unique challenges.

SBT

Science Based Targets

An initiative that empowers companies to set ambitious, science-based emissions reduction targets. These targets provide a clearly defined pathway for companies to reduce greenhouse gas (GHG) emissions, aligning with climate science. It defines and promotes best practices in science-based target setting and offers resources, guidance, and independent assessment of companies’ targets based on strict criteria.
