Rich countries' larger contribution to environmental damage means that they must shoulder greater responsibility for fixing the problem. That means changing the way they produce and consume energy - reducing subsidies, ensuring appropriate pricing, and adequately taxing environmentally damaging products.
富国对环境造成的更大程度的破坏意味着它们在解决环境问题时必须担负更多的责任。也就是说改变它们生产和消费能源的方式-减少补贴，确保合理定价及对于破坏环境的产品征收足够的税。
