Globalisation

Globalisation refers to the growing connectedness and interdependence of world cultures and economies. Technology and trade have driven this across several major waves, from the Silk Road’s early exchange of goods and ideas, to the maritime trade routes of the Age of Exploration, to the spread of revolutionary political ideals in the Age of Revolution. In the Information Age, advances in computing and communications accelerated globalisation to an unprecedented level, making economies deeply interlinked and allowing events in one region to ripple across the world.

Over the past century, national economies have become deeply integrated into a global system, with world trade expanding more than fortyfold since 1913. This growth has come in two major waves: an early 19th‑century surge driven by intra‑European trade that collapsed in the interwar period, and a post‑WWII wave enabled by new technologies like aviation and modern communications. As transaction costs fell, trade shifted from exchanging different goods between countries to exchanging similar goods within the same industries, reflecting a more complex and interconnected global economy.

Traditional measures like trade or investment flows miss how globalisation has changed. Today it is increasingly shaped by global value chains and the rapid rise of digitally delivered services, even as governments turn inward over security and supply‑chain concerns. This shift has made trade more politically contested and more concentrated among geopolitical partners.

Globalisation has generally been shown and understood to increase standards of living, but the negative impacts of globalisation on local or emerging economies and individual works is now being brought more to the forefront. For example, workers in the Global North must compete with lower-cost market jobs, while working conditions in the Global South can be deplorable and lead to an increase in child labour.

Globalisation has historically driven higher emissions because rising incomes and economic growth were tightly linked to greater fossil‑fuel use. That relationship is now weakening, and breaking it entirely is essential if the world is to eliminate poverty without accelerating climate change. Innovation spreads globally through trade and knowledge exchange, and past successes like the global phase‑out of CFCs show that shared technological progress can solve environmental problems without reducing quality of life.

Closer global ties are also critical for a rapid and fair transition to clean energy. Trade lowers the cost of renewables and enables countries to access the minerals and technologies they cannot produce themselves. Migration helps fill labour shortages in rich countries that need workers to build zero‑carbon infrastructure, and global capital markets are needed to finance clean‑energy investment in developing countries. Transport emissions from globalisation are relatively small, so cutting trade or travel would bring little climate benefit at very high cost. A sustainable future depends on deeper global cooperation, not retreating from it. (5)

Rolling back globalisation would be costly and reverse many of its gains, so the priority is to manage it better rather than retreat. That means stable global trade rules, domestic policies that share benefits more fairly, strong labour and social protections, and international institutions that help resolve tensions and support cooperation.

Humans evolved both a strong tendency to create many distinct cultures and an equally strong ability to cooperate in very large groups. This helps explain why global cultural symbols spread easily today, even as people worry about homogenisation. A single global culture is possible in theory, but resource pressures, rapid migration, and social fragmentation make full unification unlikely, and shared culture may instead become a tool for holding diverse societies together.
