Consider the following statements: 1. The Sustainable Development Goals were first proposed in 1972 by a global think tank called the 'Club of Rome'. 2. The Sustainable Development Goals have to be achieved by 2030. Which of the statements given above is/are correct?

1. Statement 1 is incorrect. The 'Club of Rome' published 'The Limits to Growth' in 1972, which discussed environmental limits, but the Sustainable Development Goals (SDGs) were formally adopted much later by the UN in 2015 as part of the 2030 Agenda. They were not proposed by the Club of Rome. 2. Statement 2 is correct. The Sustainable Development Goals (SDGs) are intended to be achieved by the target year 2030, as outlined in the UN's 'Agenda 2030 for Sustainable Development'.
