Sustainability, a term now commonly associated with global environmental and social responsibility, has evolved through various agreements over the decades. The journey began with a report known as the Brundtland Report, officially titled Our Common Future, released in 1987. Commissioned by the United Nations, this report laid the foundation for the modern understanding of sustainability. Led by former Norwegian Prime Minister Gro Harlem Brundtland, it defined sustainable development as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” The report was born out of growing concerns over environmental degradation, poverty, and inequality, marking a significant moment in recognizing the interconnectedness of these issues on a global scale.
The Brundtland Report was a response to the economic development strategies of the 1970s and early 1980s, which often prioritized industrial growth at the expense of the environment. Industrial pollution, deforestation, and the depletion of natural resources were rampant during this period. At the same time, the adverse impacts of climate change are becoming increasingly evident. The report played an important role in raising awareness that environmental sustainability and economic development should not be viewed as opposing forces but as two sides of the same coin. It highlighted the importance of adopting practices that preserve natural resources for future generations while promoting social equity.
The next major milestone following the Brundtland Report was the Earth Summit, held in Rio de Janeiro in 1992. Officially known as the United Nations Conference on Environment and Development (UNCED), this summit brought together world leaders to address pressing environmental challenges on a global stage. The summit’s outcome was the Rio Declaration on Environment and Development, which outlined 27 principles for achieving sustainable development. It also led to the establishment of two crucial treaties: the Convention on Biological Diversity and the United Nations Framework Convention on Climate Change (UNFCCC). The UNFCCC would later become a critical framework for future climate negotiations.
As the threats posed by climate change intensified, the international community reconvened under the UNFCCC for the Kyoto Protocol in 1997. This landmark agreement was the first to set legally binding targets for industrialized countries to reduce greenhouse gas emissions. While the Kyoto Protocol marked significant progress, it faced challenges in implementation, as some major polluters, such as the United States, opted not to ratify the agreement. Nonetheless, it was a key moment in recognizing the need for a global cooperative effort to tackle climate change.
Years later, after recognizing the limitations of the Kyoto Protocol and the urgency of the climate crisis, the world came together once again in 2015 for the Paris Agreement. This accord marked a new era in global climate policy by setting an ambitious target of limiting global temperature rise to well below 2°C above pre-industrial levels, with efforts to limit the increase to 1.5°C. Unlike the Kyoto Protocol, the Paris Agreement included commitments from both developed and developing countries, acknowledging the shared but differentiated responsibility in addressing climate change.

Alongside these agreements, the Conference of the Parties (COP) meetings under the UNFCCC have been instrumental in driving the sustainability agenda forward. These annual summits, held since 1995, bring together global leaders, policymakers, and activists to review progress, set new targets, and collaborate on solutions. Notable COPs include the 2015 COP21 in Paris, where the Paris Agreement was signed, and COP26 in Glasgow, which saw countries reaffirm their commitments to addressing climate change.
The path toward global sustainability has been shaped by a series of landmark agreements that reflect the growing recognition of the need to balance environmental protection with economic and social development. From the Brundtland Report to the Paris Agreement, each step in this journey underscores the importance of international cooperation in building a more sustainable future for all.
