Sanitation and wastewater treatment are key elements for global human health and aquatic biodiversity. Scenarios showed an improvement of sanitation but unimproved sanitation will not disappear before 2070. Wastewater treatment will also improve but not in all regions of the world.

This report presents cost-effective greenhouse gas emission reduction pathways for major emitting economies to keep global warming below 1.5 °C or well below 2 °C, as projected from least-cost scenarios of integrated assessment models in the IPCC AR6 scenario database.

This report presents a methodology aiming to identify the greenhouse gas emission reduction levels for 2040 and the corresponding greenhouse gas emission budgets for 2030–2050 necessary to achieve the Paris targets for maximum global temperature increases of 1.5 °C and well below 2 °C.

Access to modern, reliable and affordable energy in Africa could help address some of the social, economic, health and environmental challenges that come with the fast growing population. The continent is endowed with abundant fossil and renewable energy resources to meet the fast growing demand for energy.

Many countries have made a commitment to reduce their greenhouse gas emissions to net zero by or around 2050. If some sectors have residual emissions, these must be compensated for by removing CO2 from the air and storing it.

In 2019, the growth in global greenhouse gas (GHG) emissions (excluding those from land-use change) slowed down to 0.6%, reaching 51.7 gigatonnes of CO2 equivalent (GtCO2 eq. This revised growth rate is half of last year’s estimate of 1.1% and less than half of the average annual growth rate of 1.5% since 2005.

As negotiations continue on biodiversity action for the next decade, now is the critical moment to seize the opportunity for embedding a landscape perspective throughout the new UN Convention on Biological Diversity (CBD) post-2020 Global Biodiversity Framework (GBF).

Many measures to mitigate climate change (SDG 13) have an impact on achieving other Sustainable Development Goals (SDGs), often positive, but sometimes negative. This study shows how twenty promising climate mitigation measures affect the achievement of other SDGs for several world regions.

Global greenhouse gas (GHG) emissions have increased, on average, by 1.1% per year, from 2012 to 2019, which is a markedly lower growth rate than those seen in the first decade of this century (2.6%, on average).
