The world needs to transform the way it operates in order to meet its climate change objectives. This implies fundamental changes across all sectors, from energy production and consumption, to agricultural systems. These changes are necessary, but must be implemented without imposing undue burden on populations. Transparency can help gather and analyze the data and information needed to plan, design and evaluate policies and actions so that they can achieve transformational change and a just transition to a low-carbon economy that leaves no one behind.
