The global energy system faces deep uncertainty in the near, medium, and long terms. Amidst war in Europe, the urgent need to reduce greenhouse gas emissions, and many other factors, long-term energy outlooks offer one lens through which to assess the wide range of potential futures for global energy, emissions, and even geopolitics.

Because these projections vary widely and depend on varying underlying assumptions and methodologies, they are difficult to compare on an apples-to-apples basis. In this report, we apply a detailed harmonization process to compare 19 scenarios across seven energy outlooks published in 2021. Taken together, these scenarios offer a broad scope of potential changes to the energy system as envisioned by some of its most knowledgeable organizations. Table 1 shows the historical datasets, outlooks, and scenarios examined here.
