Free-rider problem
The incentive to benefit from a shared good, such as a stable climate, while leaving the cost of providing it to others.
Example
A country can gain from global emission cuts even if its own policies lag behind those of its neighbours.
The catch
Free-riding explains part of slow international progress, but reciprocity, co-benefits and domestic politics also shape national choices.

In more depth
Free-rider problem, explained.
The free-rider problem explains why climate cooperation leans so heavily on visibility. When every country can see what the others report, holding back becomes harder to hide and easier to criticise. The Paris Agreement is built on that logic. Each party publishes its own nationally determined contribution and reports progress under common rules. Trust can then grow without a central enforcer.
The same temptation appears inside companies, cities and shared buildings. Use the term to describe a structure of incentives. As an accusation against one actor it is weak, unless you can show that actor gaining from others' efforts while avoiding its own share. It sits close to the tragedy of the commons, which describes the shared resource being run down. Free-riding is the decision to let others pay for protecting it.
