The B1 SRES scenario has a future with economic growth, but with a strong focus on equity and sustainability. It has faster economic convergence, greater equity, and a stronger environmental protection than other scenarios. This future is characterized by:

• High levels of environmental awareness, and a global compact for sustainable development
• High investment in the efficiency of resource use leads to the rapid development and diffusion of clean technologies (i.e. clean energy, recycling, etc.)
• The development of strong welfare nets helps to prevents social exclusion, but may lead to lower economic efficiency due to large income redistribution and higher taxes on the basis of poverty.
• Similar to the A1B scenario, population peaks at 9 billion around 2050, declining to 7 billion by 2100, though the reasons for this decline are primarily social and environmental instead of economic as in A1B.
