This paper proposes an objective way of estimating and allocating “differentiated” responsibilities for carbon emissions across countries. These responsibilities translate into specific obligations and incentives for future emission reductions and support for adaptation, mitigation, and development.

This briefing looks at what the 1.5°C limit means in terms of adaptation and loss and damage for the most vulnerable countries and regions. It finds that slowing down warming is critical to buy us time to adapt and also to avoid irreversible loss and damage.

This paper offers an updated and comprehensive review of recent studies on the impact of climate change, particularly global warming, on poverty and inequality, paying special attention to data sources as well as empirical methods.

Despite government promises, warming projections have not improved since Glasgow two years ago, amid worsening climate impacts. In a year where every continent experienced record-breaking heat, wildfires, tropical cyclones or some other extreme events, there has been no discernable shift in action.

Reducing black carbon emissions will help in avoiding climate tipping points, building resilience and delivering clean air. This policy brief outlines the latest science on black carbon, examples of cost effective solutions, and recommendations for policymakers, funders and governments.

The Earth is on track to reach 3°C of warming by the end of the century under current policies – twice the amount of the Paris Agreement’s most ambitious target – this new report from UNEP reveals.

The State of the Cryosphere 2023 – Two Degrees is Too High report shows that all of the Earth’s frozen parts will experience irreversible damage at 2°C of global warming, with disastrous consequences for millions of people, societies, and nature.

Countries are planning to produce around 110 per cent more fossil fuels in 2030 than would be consistent with limiting warming to 1.5 degrees Celsius, according to this new report by the United Nations Environment Programme (UNEP).

India is expected to meet its 2030 target to have half of its electricity capacity be non-fossil well before the end of the decade, according to this IEA’s new World Energy Outlook 2023.
