The figure shows that, today, industry (if one includes non- combusted) accounts for just over half of total global consumption, buildings account for just under 30%, and transportation accounts for about 21%.TheExecutiveSummary of thisBP report also includes the following statements: • In the Evolving Transition scenario [one of several scenarios examined by BP and the one selected for discussion ‘for ease of explanation’], world GDP more than doubles by 2040, driven by increasing prosperity in Water,Energy, andEnvironment–APrimer40
